Certain terms used in this Agreement are defined in Section 16 hereof.

The Company and the Trust understand that the Underwriters propose to make a public offering of the Securities as soon as the Representatives deem advisable after this Agreement has been executed and delivered. It is understood and agreed by all parties hereto that the Company has caused the formation of the Trust and will convey, or cause to be conveyed, to the Trust, at or prior to the Closing, a net profits interest (the “Net Profits Interest”) entitling the Trust to receive 80% of the net profits from the sale of production of oil and natural gas attributable to the Company’s interest in certain oil and natural gas properties located in the Permian Basin in Texas, in exchange for [·] Trust Units.

Promptly after the execution and delivery of this Agreement, the Trust will prepare and file with the Commission a prospectus dated the date of this Agreement in accordance with the provisions of Rule 430A and Rule 424(b) and the Company has previously advised you of all information (financial and other) that will be set forth therein. Such prospectus, in the form first furnished to the Underwriters for use in connection with the offering of the Securities (whether to meet the request of purchasers pursuant to Rule 173(d) or otherwise) is herein called the “Prospectus.”

It is understood and agreed to by all parties hereto that the following transactions have occurred or will occur on or before the Closing Date (as hereinafter defined):

(a) Pursuant to a Conveyance of Net Profits Interest by and among the Company and the Trust dated as of the Closing Date (the “Conveyance”), the Company will convey to the Trust the Net Profits Interest in exchange for which [·] Trust Units will be issued to the Company.

(b) The public offering of the Initial Securities contemplated hereby will be consummated.

(c) The Trust Agreement of the Trust, by and among the Company, Simmons Bank, as trustee (the “Trustee”), and Wilmington Trust, National Association, as Delaware trustee (the “Delaware Trustee”) (the “Organizational Trust Agreement”), shall be amended and restated (as so amended and restated, the “Trust Agreement”).

(d) The Company and the Trust will enter into a registration rights agreement granting registration rights to the Company with respect to the Trust Units it will own after the completion of the offering of the Securities (the “Registration Rights Agreement”).

The transactions described above are referred to, collectively as, the “Transactions.” The “Transaction Documents” shall mean the Conveyance and the Registration Rights Agreement. The “Organizational Documents” shall mean the Organizational Trust Agreement, the Trust Agreement, the Certificate of Trust of the Trust, the Certificate of Formation of the Company and the Limited Liability Company Agreement of the Company, in each case as amended to date. The “Operative Agreements” shall mean the Transaction Documents, the Organizational Trust Agreement and the Trust Agreement.

SECTION 1. Representations and Warranties.

(a) Representations and Warranties by the Trust and the Company. Each of the Trust and the Company represents and warrants to each Underwriter as of the date hereof, as of the Applicable Time, and agrees with each Underwriter, as follows:

(1) Compliance with Registration Requirements. The Securities have been duly registered under the 1933 Act pursuant to the Registration Statement. Each of the Initial Registration Statement and any post-effective amendments thereto have been declared effective under the 1933 Act and any Rule 462(b) Registration Statement has become effective under the 1933 Act or, not later than 8:00 a.m. (New York City time) on the business day immediately after the date of this Agreement, will become effective under the 1933 Act, and no stop order suspending the effectiveness of the Initial Registration Statement or any Rule 462(b) Registration Statement has been issued under the 1933 Act and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Trust or the Company, are contemplated by the Commission, and any request on the part of the Commission for additional information has been complied with. The Initial Registration Statement was initially filed with the Commission on [·], 2018.

(2) Registration Statement, Prospectus and Disclosure at Time of Sale. At the respective times that the Initial Registration Statement, any Rule 462(b) Registration Statement and any amendments to any of the foregoing were declared or became effective, as the case may be, and at the Closing Date (and, if any Option Securities are purchased, at the applicable Option Closing Date), the Initial Registration Statement, any Rule 462(b) Registration Statement and any amendments to any of the foregoing complied and will comply in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations and did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

At the respective times the Prospectus or any amendment or supplement thereto was filed pursuant to Rule 424(b), at the Closing Date (and, if any Option Securities are purchased, at the applicable Option Closing Date), and at any time when a prospectus is required (or, but for the provisions of Rule 172, would be required) by applicable law to be delivered in connection with sales of Securities (whether to meet the requests of purchasers pursuant to Rule 173(d) or otherwise), neither the Prospectus nor any amendments or supplements thereto included or will include an untrue statement of a material fact or omitted or will omit 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.

2

As of the Applicable Time (except in the case of clause (y) below), neither (w) any Issuer General Use Free Writing Prospectuses, if any, issued at or prior to the Applicable Time, the Pre-Pricing Prospectus as of the Applicable Time and the information, if any, included on Exhibit H hereto, all considered together (collectively, the “General Disclosure Package”), nor (x) any individual Issuer Limited Use Free Writing Prospectus, when considered together with the General Disclosure Package, nor (y) any Issuer General Use Free Writing Prospectus issued subsequent to the Applicable Time, when considered together with the General Disclosure Package, included or will include an untrue statement of a material fact or omitted or will omit 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.

Each preliminary prospectus and the Prospectus and any amendments or supplements to any of the foregoing filed as part of the Registration Statement or any amendment thereto, or filed pursuant to Rule 424 under the 1933 Act, or delivered to the Underwriters for use in connection with the offering of the Securities, complied when so filed or when so delivered, as the case may be, in all material respects with the 1933 Act and the 1933 Act Regulations.

The representations and warranties in the preceding paragraphs of this Section 1(a)(2) do not apply to statements in or omissions from the Registration Statement, any preliminary prospectus, the Prospectus or any Issuer Free Writing Prospectus or any amendment or supplement to any the foregoing made in reliance upon and in conformity with written information furnished to the Trust or the Company by any Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by the Underwriters as aforesaid consists of the information described as such in Section 7(b) hereof.

At the respective times that the Initial Registration Statement, any Rule 462(b) Registration Statement or any amendment to any of the foregoing were filed and at the date hereof, the Trust was not and is not an “ineligible issuer” as defined in Rule 405, in each case without taking into account any determination made by the Commission pursuant to paragraph (2) of the definition of such term in Rule 405; and, without limitation to the foregoing, the Trust has at all relevant times met, meets and will at all relevant times meet the requirements of Rule 164 for the use of a free writing prospectus (as defined in Rule 405) in connection with the offering contemplated hereby.

The copies of the Initial Registration Statement and any Rule 462(b) Registration Statement and any amendments to any of the foregoing and the copies of each preliminary prospectus, each Issuer Free Writing Prospectus that is required to be filed with the Commission pursuant to Rule 433 and the Prospectus and any amendments or supplements to any of the foregoing, that have been or subsequently are delivered to the Underwriters in connection with the offering of the Securities (whether to meet the request of purchasers pursuant to Rule 173(d) or otherwise) were and will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T. For purposes of this Agreement, references to the “delivery” or “furnishing” of any of the foregoing documents to the Underwriters, and any similar terms, include, without limitation, electronic delivery.

The Company and the Trust have made available a “bona fide electronic road show” (as defined in Rule 433(h)) in compliance with Rule 433(d)(8)(ii) such that no filing with the Commission of any “road show” (as defined in Rule 433(h)) is required in connection with the offering of the Securities.

Each Issuer Free Writing Prospectus (if any), as of its issue date and at all subsequent times through the completion of the public offering and sale of the Securities, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement, any preliminary prospectus or the Prospectus that has not been superseded or modified.

The Company and the Trust have filed publicly on EDGAR at least 15 calendar days prior to any “road show” (as defined in Rule 433 under the Securities Act), any confidentially submitted registration statement and registration statement amendments relating to the offer and sale of the Trust Units.

(3) Emerging Growth Company. From the time of initial confidential submission of the Registration Statement to the Commission (or, if earlier, the first date on which the Trust engaged directly or through any person authorized to act on its behalf in any Testing-the-Waters Communication) through the date hereof, the Trust has been and is an “emerging growth company,” as defined in Section 2(a) of the 1933 Act (an “Emerging Growth Company”).

(4) Testing-the-Waters Materials. Neither the Company nor the Trust (i) has engaged in any Testing-the-Waters Communications other than Testing-the-Waters Communications with the consent of the Representatives with entities that are qualified institutional buyers within the meaning of Rule 144A under the 1933 Act or institutions that are accredited investors within the meaning of Rule 501 under the 1933 Act and (ii) has authorized anyone other than the Representatives to engage in Testing-the-Waters Communications. Each of the Company and the Trust reconfirms that the Representatives have been authorized to act on their behalf in undertaking Testing-the-Waters Communications. Neither the Company nor the Trust has distributed or approved for distribution any Written Testing-the-Waters Communications other than those listed on Exhibit J hereto. Any individual Written Testing-the-Waters Communication does not conflict with the information contained in the Registration Statement or the General Disclosure Package, complied in all material respects with the 1933 Act, and when taken together with the General Disclosure Package as of the Applicable Time, did not, and as of the Closing Date and as of any Option Closing Date, as the case may be, will not, contain any untrue statement of a material fact or omit 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.

(5) The Transactions. The Transactions have been or will be consummated, as the case may be, on or prior to the respective times contemplated by the preamble of this Agreement (or such earlier times as may be contemplated by the Pre-Pricing Prospectus or the Prospectus) on the terms contemplated by this Agreement, the Pre-Pricing Prospectus and the Prospectus.

(6) Independent Accountants. The accountants who certified the financial statements of the Trust (including the related notes thereto) included in the Registration Statement, the General Disclosure Package and the Prospectus are and were during the periods covered by such financial statements, independent public accountants with respect to the Trust as required by the 1933 Act, the 1933 Act Regulations and the PCAOB.

(7) Formation, Due Qualification and Authority of the Trust. The Trust has been duly formed and is validly existing and in good standing as a statutory trust under the Delaware Statutory Trust Act and all filings required under the laws of the State of Delaware with respect to the formation and valid existence of the Trust as a statutory trust have been made. The Trust is duly registered and qualified to do business and is in good standing in each jurisdiction or place where the nature of its properties or the conduct of its business requires such registration or qualification, except where the failure to be so registered or qualified or in good standing would not, in the aggregate, reasonably be expected to (i) have a material adverse effect on the condition (financial or otherwise), results of operations, properties, business or prospects of the Trust or the Underlying Properties (as defined in the Registration Statement, the Pre-Pricing Prospectus and the Prospectus) (a “Material Adverse Effect”), (ii) materially impair the ability of the Trust to consummate the transactions contemplated by this Agreement or any other transactions provided for in this Agreement or the Operative Agreements or (iii) subject the unitholders of the Trust to any material liability or disability. The Trust has full right, power and authority necessary to own or hold its properties and to conduct the businesses in which it is engaged as described in the Registration Statement, the Pre-Pricing Prospectus and the Prospectus. The Trust does not own or control, directly or indirectly, any corporation, association or other entity.

(8) Outstanding Trust Units. At the Closing Date, after giving effect to the Transactions, the Trust will have outstanding [·] Trust Units; such Trust Units and the beneficial interests in the Trust represented thereby will be duly authorized and validly issued in accordance with the Trust Agreement, and will be fully paid and nonassessable and free from any preemptive or similar rights.

4

(9) Enforceability of Operative Agreements. Each of the Operative Agreements to which the Trust is a party has been or at the Closing will be duly authorized, executed and delivered by the Trust, and is a valid and legally binding agreement of the Trust, enforceable against it in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

(10) Authorization of Agreement. This Agreement has been duly authorized and validly executed and delivered by the Trust.

(11) Authorization of Securities. The Trust has all requisite power and authority to execute and deliver this Agreement and to perform its obligations hereunder. The Trust has all requisite power and authority to issue, sell and deliver the Trust Units to the Company in accordance with and upon the terms and conditions set forth in the Trust Agreement, the Registration Statement, the Pre-Pricing Prospectus and the Prospectus. At the Closing Date and each Option Closing Date, as applicable, all trust action required to be taken by the Trust, the Company, the Trustee or the Delaware Trustee for the authorization, issuance, sale and delivery of the Trust Units, the execution and delivery of the Operative Agreements to which the Trust is a party and the consummation by the Trust of the transactions contemplated by this Agreement and the Operative Agreements to which the Trust is a party shall have been validly taken by the Trust. The holders of the Trust Units, upon the issuance thereof, will be entitled to the benefits of the Trust Agreement.

(12) Description of Securities. The Trust Units conform in all material respects to the descriptions thereof contained in the Registration Statement, the General Disclosure Package and the Prospectus.

(13) Absence of Defaults and Conflicts. The Trust is not, and upon the consummation of the Transactions will not be, in violation of the Trust Agreement or in default in the performance or observance of any obligation, agreement, covenant or condition contained in the Organizational Trust Agreement, the Trust Agreement and the Certificate of the Trust (together, the “Trust Documents”). The execution, delivery and performance of this Agreement and the consummation of the transactions contemplated herein and in the Registration Statement, the General Disclosure Package and the Prospectus (including the issuance and sale of the Securities and the use of the net proceeds from the sale of the Securities as described in the Pre-Pricing Prospectus and the Prospectus under the caption “Use of Proceeds”) and compliance by the Trust with its obligations under this Agreement do not and will not, whether with or without the giving of notice or passage of time or both, (A) conflict with or constitute a breach of, or default under any Trust Documents, (B) conflict with, constitute a breach or violation of, or a default (or an event which, with notice or lapse of time or both, would constitute such a default) under any indenture, mortgage, deed of trust, loan agreement, lease or other agreement or instrument to which the Trust is a party or by which any of its properties may be bound, (C) violate any statute, law, regulation, ruling or any order, judgment, decree or injunction of any court or governmental agency or body applicable to the Trust or its properties in a proceeding to which it or its properties is a party or is bound, or (D) result in the creation or imposition of a Lien upon any property or assets of the Trust, except with respect to (B) through (D) for such conflicts, breaches, defaults or Liens that would not, individually or in the aggregate, result in a Material Adverse Effect or materially impair the ability of the Trust to consummate the Transactions or any other transactions provided for in this Agreement or the Transaction Documents.

(14) Absence of Proceedings. There is no action, suit, proceeding, inquiry or investigation before or brought by any court or governmental agency or body, domestic or foreign, now pending, or, to the knowledge of the Trust or the Company, threatened, against or affecting the Trust or the business or assets of the Trust which is required to be disclosed in the Registration Statement, the Pre-Pricing Prospectus or the Prospectus (other than as disclosed therein), or which would reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect or to materially impair the ability of the Trust to consummate the transactions contemplated in this Agreement or the Transaction

5

Documents to which the Trust is a party; the aggregate of all pending legal or governmental proceedings to which the Trust is a party or of which any of their respective property or assets is the subject which are not described in the Registration Statement, the Pre-Pricing Prospectus and the Prospectus, including ordinary routine litigation incidental to the business, would not reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect.

(15) Accuracy of Descriptions and Exhibits. The information in the Pre-Pricing Prospectus and the Prospectus under the captions “Pro Forma and Projected Cash Available for Distribution by the Trust,” “The Underlying Properties,” “Computation of Net Profits,” “Description of the Trust Agreement,” “Description of the Trust Units,” “Certain Relationships and Related Party Transactions,” “Trust Units Eligible for Future Sale,” “Federal Income Tax Considerations,” “State Tax Considerations” and “Certain ERISA Considerations,” and the information in the Registration Statement under Items 14 and 15, in each case to the extent that it constitutes matters of law, summaries of legal matters, summaries of provisions of the Organizational Documents or any other instruments or agreements, summaries of legal proceedings, or legal conclusions, is correct in all material respects; and there are no franchises, contracts, indentures, mortgages, deeds of trust, loan or credit agreements, bonds, notes, debentures, evidences of indebtedness, leases or other instruments, agreements or documents required to be described or referred to in the Registration Statement, the Pre-Pricing Prospectus or the Prospectus or to be filed as exhibits to the Registration Statement which have not been so described and filed as required.

(16) No Changes Since Trust Formation. Since the date the Trust was formed through the date hereof, and except as may otherwise be disclosed in the Registration Statement, the most recent Pre-Pricing Prospectus or the Prospectus, the Trust has not (i) issued or granted any Trust Units or securities exchangeable for or convertible into Trust Units incurred in the ordinary course of business and except for this Agreement and the Operative Agreements, (ii) entered into any transaction not in the ordinary course of business or (iii) made any distribution on its equity interests.

(17) Authorization and Qualification of Trustee. The Trustee is a state banking association duly authorized and empowered to act as trustee of the Trust pursuant to the Organizational Trust Agreement and the Trust Agreement.

(18) Authorization and Qualification of Delaware Trustee. The Delaware Trustee is a national banking association duly authorized and empowered to act as the Delaware trustee of the Trust pursuant to the Organizational Trust Agreement and the Trust Agreement.

(19) No Consent Needed for Trustee Action. No consent, approval, authorization or filing is required under any law, rule or regulation of the State of Texas or of the United States of America, in order to permit the Trustee to act as trustee of the Trust.

(20) Absence of Further Requirements. (A) No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court or governmental authority or agency, domestic or foreign, having jurisdiction over the Trust or its properties, (B) no authorization, approval, vote or consent of any holder of capital stock or other securities of the Trust, (C) no authorization, approval, waiver or consent of the Trustee under any Trust Documents, and (D) no authorization, approval, vote or consent of any other person or entity under any agreement to which this Trust is a party, is necessary or required for the authorization, execution, delivery or performance by the Trust of this Agreement, for the offering of the Securities as contemplated by this Agreement, for the issuance by the Trust of the Securities, and the sale or delivery of the Securities to be sold by the Company pursuant to this Agreement, or for the consummation of any of the other transactions contemplated by this Agreement, in each case on the terms contemplated by the Registration Statement, the General Disclosure Package and the Prospectus, except (1) for such consents that have been obtained under the 1933 Act, the 1933 Act Regulations and filings required under the 1934 Act and 1934 Act Regulations and except that no representation is made as to such as may be required under state or foreign securities laws, (ii) for such consents that have been, or prior to the Closing Date will be, obtained or made, and (iii) for such consents that, if not obtained, have not had and would not reasonably be expected to materially impair the ability

6

of the Trust or the Company to consummate the Transactions or any other transactions provided for in this Agreement or the Transaction Documents to which it is a party.

(21) Investment Company Act. The Trust is not, and after giving effect to the offer and sale of the Securities and the application of the net proceeds as described in the General Disclosure Package and the Prospectus under the caption “Use Of Proceeds,” will not be, an “investment company” as defined in the 1940 Act, and the rules and regulations of the Commission thereunder.

(22) Absence of Registration Rights. The Trust is not a party to any registration rights agreements, co-sale agreements, tag-along agreements or other similar agreements. The Registration Rights Agreement to be entered into in connection with the transactions contemplated by this Agreement does not provide any rights in connection with this offering, and there are no persons with registration rights or other similar rights to have any securities (debt or equity) registered pursuant to the Registration Statement or included in the offering contemplated by this Agreement or otherwise registered by the Trust under the 1933 Act, and there are no persons with co-sale rights, tag-along rights or other similar rights to have any securities (debt or equity) included in the offering contemplated by this Agreement.

(23) NYSE. The outstanding Trust Units and the Securities being sold hereunder by the Company have been approved for listing, subject only to official notice of issuance, on the NYSE.

(24) Tax Returns. The Trust has filed all foreign, federal, state and local tax returns that are required to be filed or have obtained extensions thereof, except where the failure so to file would not, individually or in the aggregate, result in a Material Adverse Effect, and subject to permitted extensions, have paid all taxes (including, without limitation, any estimated taxes) required to be paid and any other assessment, fine or penalty, to the extent that any of the foregoing is due and payable, except for any such tax, assessment, fine or penalty that is currently being contested in good faith by appropriate actions and except for such taxes, assessments, fines or penalties the nonpayment of which would not, individually or in the aggregate, result in a Material Adverse Effect.

(25) Accounting and Disclosure Controls. The Trust maintains and has established and maintained effective “internal control over financial reporting” (as defined in Rule 13a-15 of the 1934 Act Regulations). The Trust maintains a system of internal accounting controls sufficient to provide reasonable assurance that (A) transactions are executed in accordance with the general or specific authorizations of management or the Trustee, as applicable; (B) transactions are recorded as necessary to permit preparation of financial statements in conformity with a modified cash basis of accounting and to maintain asset accountability; (C) access to assets is permitted only in accordance with the general or specific authorization of management or the Trustee, as applicable; and (D) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. Except as described in the Registration Statement, the General Disclosure Package and the Prospectus, there has not been (1) any material weakness (as defined in Rule 1-02 of Regulation S-X of the Commission) in the Trust’s internal control over financial reporting (whether or not remediated), or (2) any fraud, whether or not material, involving management, the Trustee or other employees who have a role in the Trust’s internal control over financial reporting and, since the end of the Trust’s most recent fiscal year for which audited financial statements are included in the Registration Statement, the General Disclosure Package and the Prospectus, there has been no change in the Trust’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Trust’s internal control over financial reporting.

The Trust’s independent public accountants have been advised of all material weaknesses, if any, and significant deficiencies (as defined in Rule 1-02 of Regulation S-X of the Commission), if any, in the Trust’s internal control over financial reporting and of all fraud, if any, whether or not material, involving management, the Trustee or other employees who have a role in the Trust’s internal controls and financial reports, in each case that occurred or existed, or was first detected.

(26) Compliance with the Sarbanes-Oxley Act. The Trust has taken all necessary action to ensure that, upon and at all times after the filing of the Registration Statement, the Trust will be in

7

compliance in all material respects with all applicable and effective provisions of the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in connection therewith and the rules of The New York Stock Exchange that are effective and applicable to the Trust.

(27) Pending Proceedings and Examinations; Comment Letters. The Registration Statement is not the subject of a pending proceeding or examination under Section 8(d) or 8(e) of the 1933 Act, and the Trust is not the subject of a pending proceeding under Section 8A of the 1933 Act. The Trust has provided the Representatives with true, complete and correct copies of any written comments received from the Commission by the Trust or its legal counsel or accountants, and of any transcripts made by the Trust, its legal counsel or accountants of any oral comments received from the Commission, with respect to the Registration Statement, any preliminary prospectus, the Prospectus, any Issuer Free Writing Prospectus or any amendments or supplements to any of the foregoing and of all written responses thereto, and no such comments remain unresolved.

(28) Absence of Manipulation. The Trust has not taken and will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in the stabilization or manipulation of the price of any security of the Trust in connection with the offering of the Securities.

(29) No Unlawful Payments. Neither the Trust, nor to the knowledge of the Trust or the Company, any agent, employee, trustee or affiliate or other person associated with or acting on behalf of the Trust is aware of or has taken any action, directly or indirectly, that has resulted or would result in (i) the use of any funds for any unlawful contribution, gift, entertainment or other unlawful expense relating to political activity; (ii) the making or taking of an act in furtherance of an offer, promise or authorization of any direct or indirect unlawful payment or benefit to any foreign or domestic government or regulatory official or employee, including of any government-owned or controlled entity or of a public international organization, or any person acting in an official capacity for or on behalf of any of the foregoing, or any political party or party official or candidate for political office; (iii) a violation by any such person of any provision of the Foreign Corrupt Practices Act of 1977, as amended, or any applicable law or regulation implementing the OECD Convention on Combating Bribery of Foreign Public Officials in International Business Transactions, or committed an offence under the Bribery Act 2010 of the United Kingdom, or any other applicable anti-bribery or anti-corruption laws; or (iv) the making, offering, requesting or taking of, or the agreement to take, an act in furtherance of any unlawful bribe or other unlawful benefit, including, without limitation, any rebate, payoff, influence payment, kickback or other unlawful or improper payment or benefit.

(30) Compliance with Money Laundering Laws. The operations of the Trust are and have been conducted at all times in compliance with applicable financial recordkeeping and reporting requirements, including those of the Currency and Foreign Transactions Reporting Act of 1970, as amended, the applicable money laundering statutes of all applicable jurisdictions, the rules and regulations thereunder and any related or similar rules, regulations or guidelines issued, administered or enforced by any governmental or regulatory agency (collectively, the “Anti-Money Laundering Laws”) and no action, suit or proceeding by or before any court or governmental or regulatory agency, authority or body or any arbitrator involving the Trust with respect to the Anti-Money Laundering Laws is pending or, to the knowledge of the Trust or the Company, threatened.

(31) No Conflicts with Sanction Laws. Neither the Trust, nor to the knowledge of the Trust or the Company, any agent, employee, trustee or affiliate or other person associated with or acting on behalf of the Trust is currently the subject or the target of any sanctions administered or enforced by the U.S. Government, (including, without limitation, OFAC or the U.S. Department of State and including, without limitation, the designation as a “specially designated national” or “blocked person”), the UNSC, the European Union, Her Majesty’s Treasury (“HMT”), or other relevant sanctions authority (collectively, “Sanctions”), nor is the Trust organized or resident in a country or territory that is the subject or the target of Sanctions, including, without limitation, Cuba, Burma (Myanmar), Iran, North Korea, Sudan and Syria (each, a “Sanctioned Country”); and neither the Trust nor the Company will directly or indirectly use any of the proceeds of the offering, or lend, contribute or otherwise make available such proceeds to any

(38) No Material Changes. Except as disclosed in the Registration Statement, the Pre-Pricing Prospectus and the Prospectus (or any amendment or supplement thereto), since the respective dates as of which information is given in the Registration Statement, the Pre-Pricing Prospectus and the Prospectus, (i) the Company has not incurred any material liabilities or obligations, indirect, direct or contingent, or entered into any transaction that is not in the ordinary course of business, (ii) neither the Company nor the Underlying Properties has sustained any material loss or interference with its business or properties from fire, flood, windstorm, accident or other calamity, whether or not covered by insurance, (iii) the Company is not in default under the terms of any class of membership interest of the Company or any outstanding debt obligations, (iv) there has not been any material change in the indebtedness of the Company (other than in the ordinary course of business) and (v) there has not been any material adverse change, or any development involving or that had or will have a Material Adverse Effect, in the condition (financial or otherwise), business, properties, prospects, net worth or result of operations of the Company or the Underlying Properties.

(41) Related Party Transactions. There are no business relationships or related party transactions involving the Company or any of its subsidiaries or, to the knowledge of the Company, any other person that are required to be described in the Pre-Pricing Prospectus or the Prospectus that have not been described as required.

(47) Solvency. Immediately after the Closing Date, the Company (after giving effect to the Conveyance and the other transactions contemplated hereby) will be Solvent.

The Company has not sold any securities that would be integrated with the offering of the Units contemplated by this Agreement pursuant to the Securities Act or the interpretations thereof by the Commission.

SECTION 2. Sale and Delivery to Underwriters; Closing.

(a) Initial Securities. On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company agrees to sell to the Underwriters, severally and not jointly, [·] Initial Securities, and each Underwriter, severally and not jointly, agrees to purchase the respective number of Initial Securities set forth opposite its name in Exhibit A hereto plus any additional number of Initial Securities which such Underwriter may become obligated to purchase pursuant to the provisions of Section 11 hereof, subject to such adjustments among the Underwriters as the Representatives in their sole discretion shall make to eliminate any sales or purchases of fractional Securities, in each case at a price of $[·] per Trust Unit (the “Purchase Price”).

(b) Option Securities. In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company hereby grants an option to the Underwriters, severally and not jointly, to purchase up to [·] Option Securities at a price per Trust Unit equal to the Purchase Price referred to in Section 2(a) above; provided that the price per Trust Unit for any Option Securities shall be reduced by an amount per Trust Unit equal to any dividends or distributions declared, paid or payable by the Trust on the Initial Securities but not payable on such Option Securities. The option hereby granted will expire at 11:59 P.M. (New York City time) on the 30th day after the date hereof and may be exercised in whole or in part from time to time only for the purpose of covering over-allotments which may be made in connection with the offering and distribution of the Initial Securities upon notice by the Representatives to the Trust and the Company setting forth the number of Option Securities as to which the several Underwriters are then exercising the option and the time and date of payment and delivery for such Option Securities. Any such time and date of delivery (an “Option Closing Date”) shall be determined by the Representatives, but shall not be later than seven full business days after the exercise of said option (unless postponed in accordance with the provisions of Section 11), nor in any event prior to the Closing Date. If the

20

option is exercised as to all or any portion of the Option Securities, the Company will sell to the Underwriters all of the total number of Option Securities then being purchased, and each of the Underwriters, acting severally and not jointly, will purchase that proportion of the total number of Option Securities then being purchased which the number of Initial Securities set forth in Exhibit A opposite the name of such Underwriter, plus any additional number of Initial Securities which such Underwriter may become obligated to purchase pursuant to the provisions of Section 11 hereof, bears to the total number of Initial Securities, subject in each case to such adjustments as the Representatives in their discretion shall make to eliminate any sales or purchases of fractional units.

(c) Payment. Payment of the purchase price for, and delivery of, the Initial Securities shall be made at the offices of Vinson & Elkins L.L.P., 1001 Fannin St., Suite 2500, Houston, Texas 77002, or at such other place as shall be agreed upon by the Representatives, the Trust and the Company, at 9:00 A.M. (New York City time) on [·], 2018 (unless postponed in accordance with the provisions of Section 11), or such other time not later than five business days after such date as shall be agreed upon by the Representatives and the Company (such time and date of payment and delivery being herein called “Closing Date”).

In addition, in the event that any or all of the Option Securities are purchased by the Underwriters, payment of the purchase price for, and delivery of, such Option Securities shall be made at the above-mentioned offices at 9:00 A.M. (New York City time), or at such other place as shall be agreed upon by the Representatives and the Company, on each Option Closing Date as specified in the notice from the Representatives to the Company.

Payment shall be made to the Company by wire transfer of immediately available funds to a single bank account designated by the Company, in each case against delivery to the Representatives for the respective accounts of the Underwriters of the Securities to be purchased by them. It is understood that each Underwriter has authorized the Representatives, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Initial Securities and the Option Securities, if any, which it has agreed to purchase. Wells Fargo, individually and not as Representative of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Initial Securities or the Option Securities, if any, to be purchased by any Underwriter whose funds have not been received by the Closing Date or the relevant Option Closing Date, as the case may be, but such payment shall not relieve such Underwriter from its obligations hereunder.

(d) Delivery of Securities. Delivery of the Initial Securities and any Option Securities shall be made through the facilities of DTC unless the Representatives shall otherwise instruct.

SECTION 3. Covenants of the Trust and the Company. Each of the Trust and the Company, as applicable, covenants with each Underwriter as follows:

(a) Compliance with Securities Regulations and Commission Requests. The Company and the Trust, subject to Section 3(b), will comply with the requirements of Rule 430A and Rule 433 and will notify the Representatives immediately, and confirm the notice in writing, (i) when the Initial Registration Statement, any Rule 462(b) Registration Statement or any post-effective amendment to the Registration Statement shall be declared or become effective, or when any preliminary prospectus, the Prospectus, any Issuer Free Writing Prospectus or any Written Testing-the-Waters Communication or any amendment or supplement to any of the foregoing shall have been filed or distributed, (ii) of the receipt of any comments from the Commission (and shall promptly furnish the Representatives with a copy of any comment letters and shall furnish the Representatives with copies of any written responses thereto a reasonable amount of time prior to the proposed filing thereof with the Commission and will not file any such response to which the Representatives or counsel for the Underwriters shall reasonably object), (iii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to any preliminary prospectus or the Prospectus, or any Issuer Free Writing Prospectus or for additional information, including, but not limited to, any request for information concerning any Testing-the-Waters Communication, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of any preliminary prospectus, the Prospectus or any Issuer Free Writing Prospectus or any Written Testing-the-Waters Communication or any amendment or supplement to any of the foregoing, or any notice from the Commission objecting to the use of the form of the Registration Statement or any post-effective amendment thereto, or of the suspension of the qualification of the Securities for offering or sale in any jurisdiction or of the loss or suspension of any

21

exemption from any such qualification, or of the initiation or threatening of any proceedings for any of such purposes, or of any examination pursuant to Section 8(e) of the 1933 Act concerning the Registration Statement and (v) if the Trust becomes the subject of a proceeding under Section 8A of the 1933 Act in connection with the offering of the Securities prior to the Closing Date or any Option Closing Date. The Company and the Trust will make every reasonable effort to prevent the issuance of any stop order and the suspension or loss of any qualification of the Securities for offering or sale and any loss or suspension of any exemption from any such qualification, and if any such stop order is issued, or any such suspension or loss occurs, to obtain the lifting thereof at the earliest possible moment.

(b) Filing of Amendments. The Company and the Trust will give the Representatives notice of their intention to file or prepare any amendment to the Registration Statement, any Rule 462(b) Registration Statement or any Issuer Free Writing Prospectus or any Written Testing-the-Waters Communication or any amendment, supplement or revision to any preliminary prospectus, the Prospectus, or any Issuer Free Writing Prospectus or any Written Testing-the-Waters Communication, whether pursuant to the 1933 Act or otherwise, and the Company will furnish the Representatives with copies of any such documents within a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which the Representatives or counsel for the Underwriters shall reasonably object. The Trust will give the Representatives notice of its intention to make any filing pursuant to the 1934 Act or the 1934 Act Regulations from the Applicable Time through the Closing Time.

(c) Delivery of Registration Statements. The Company and the Trust have furnished or will deliver to the Representatives and counsel for the Underwriters, without charge, copies of the Initial Registration Statement and any Rule 462(b) Registration Statement and of each amendment thereto (including exhibits filed therewith) and copies of all consents and certificates of experts.

(d) Delivery of Prospectuses. The Company and the Trust have delivered to each Underwriter, without charge, as many copies of each preliminary prospectus and any amendments or supplements thereto as such Underwriter reasonably requested, and each of the Company and the Trust hereby consents to the use of such copies for purposes permitted by the 1933 Act. The Company and the Trust will furnish to each Underwriter, without charge, during the period when the Prospectus is required (or, but for the provisions of Rule 172, would be required) to be delivered by applicable law, such number of copies of the Pre-Pricing Prospectus, the Prospectus and any Issuer Free Writing Prospectus and any amendments or supplements to any of the foregoing as such Underwriter may reasonably request.

(e) Continued Compliance with Securities Laws. The Company and the Trust will comply with the 1933 Act and the 1933 Act Regulations so as to permit the completion of the distribution of the Securities as contemplated by this Agreement, the General Disclosure Package and the Prospectus. If at any time when a prospectus is required (or, but for the provisions of Rule 172, would be required) by the applicable law to be delivered in connection with sales of the Securities, any event shall occur or condition shall exist as a result of which it is necessary, in the judgment of the Trust, the Company or the Representatives, to amend the Registration Statement or amend or supplement the General Disclosure Package or the Prospectus so that the Registration Statement, the General Disclosure Package or the Prospectus, as the case may be, will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made or then prevailing, not misleading or to comply with the requirements of the 1933 Act and the 1933 Act Regulations, the Company and the Trust will promptly notify the Representatives of such event or condition and of its intention to file such amendment or supplement and will promptly prepare and file with the Commission, subject to Section 3(b) hereof, such amendment or supplement as may be necessary to correct such untrue statement or omission or to comply with such requirements, and, in the case of an amendment or post-effective amendment to the Registration Statement, each of the Company and the Trust will use its best efforts to have such amendment declared or become effective as soon as practicable, and the Company and the Trust will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request. If at any time an Issuer Free Writing Prospectus conflicts with the information contained in the Registration Statement or if an event shall occur or condition shall exist as a result of which it is necessary, in the judgment of the Trust, the Company or the Representatives, to amend or supplement such Issuer Free Writing Prospectus so that it will not include an

22

untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made or then prevailing, not misleading, or if it is necessary to amend or supplement such Issuer Free Writing Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company and the Trust will promptly notify the Representatives of such event or condition and of its intention to file such amendment or supplement and will promptly prepare and, if required by the 1933 Act or the 1933 Act Regulations, file with the Commission, subject to Section 3(b) hereof, such amendment or supplement as may be necessary to eliminate or correct such conflict, untrue statement or omission or to comply with such requirements, and the Company and the Trust will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request.

(f) Blue Sky and Other Qualifications. Each of the Company and the Trust will use its best efforts, in cooperation with the Underwriters, to qualify the Securities for offering and sale, or to obtain an exemption for the Securities to be offered and sold, under the applicable securities laws of such states and other jurisdictions (domestic or foreign) as the Representatives may reasonably designate and to maintain such qualifications and exemptions in effect for so long as required for the distribution of the Securities (; provided, however, that the Company and the Trust shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject. In each jurisdiction in which the Securities have been so qualified or exempt, the Company and the Trust will file such statements and reports as may be required by the laws of such jurisdiction to continue such qualification or exemption, as the case may be, in effect for so long as required for the distribution of the Securities.

(g) Rule 158. The Trust will timely file such reports pursuant to the 1934 Act as are necessary in order to make generally available to its securityholders as soon as practicable an earnings statement (which need not be audited) for the purposes of, and to provide to the Underwriters the benefits contemplated by, the last paragraph of Section 11(a) of the 1933 Act.

(h) Use of Proceeds. The Company will use the net proceeds received by it from the sale of the Securities in the manner specified in the Pre-Pricing Prospectus and the Prospectus under “Use of Proceeds.”

(i) issue, 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 any Trust Units or any securities convertible into or exercisable or exchangeable for Trust Units or other capital stock;

(ii) file or cause the filing of any registration statement under the 1933 Act with respect to any Trust Units or other capital stock or any securities convertible into or exercisable or exchangeable for any Trust Units or other capital stock (other than any Rule 462(b) Registration Statement filed to register Securities to be sold to the Underwriters pursuant to this Agreement); or

(iii) enter into any swap or other agreement, arrangement, hedge or transaction that transfers to another, in whole or in part, directly or indirectly, any of the economic consequences of ownership of any Trust Units or other capital stock or any securities convertible into or exercisable or exchangeable for any Trust Units or other capital stock,

23

whether any transaction described in clause (i) or (iii) above is to be settled by delivery of Trust Units, other capital stock, other securities, in cash or otherwise, or publicly announce any intention to do any of the foregoing.

Notwithstanding the provisions set forth in the immediately preceding paragraph, the following may occur, without the prior written consent of Wells Fargo, Goldman Sachs & Co. LLC and UBS Securities LLC:

SECTION 7. Indemnification.

(a) Indemnification by the Company. The Company and the Trust (but as to the Trust, solely from the assets of the Trust and without liability or obligation of the Trustee or any Trust Unitholder) each hereby agrees to indemnify and hold harmless each Underwriter, its affiliates, and its and their officers, directors, employees, partners and members and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading, or arising out of any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus, any Issuer Free Writing Prospectus, any Written Testing-the-Waters Communication, the General Disclosure Package or the Prospectus (or any amendment or supplement to any of the foregoing), or in any “issuer information” (as defined in Rule 433), or in any “road show” (as defined in Rule 433) that does not constitute an Issuer Free Writing Prospectus, or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any

29

governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 7(d) below) any such settlement is effected with the written consent of the Company and the Trust; and

(iii) against any and all expense whatsoever, as incurred (including the reasonable fees and disbursements of counsel), reasonably incurred in investigating, preparing for or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above,

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company or the Trust by any Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto), or in any preliminary prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or in any amendment or supplement to any of the foregoing), it being understood and agreed that the only such information furnished by the Underwriters as aforesaid consists of the information described as such in Section 7(b) hereof.

(b) Indemnification by the Underwriters. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Trust, its trustees, the Company, its directors, officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section 7, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), or in any preliminary prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement to any of the foregoing), in reliance upon and in conformity with written information furnished to the Company or the Trust by such Underwriter through the Representatives expressly for use therein. The Trust and the Company each hereby acknowledges and agrees that the information furnished to the Trust and the Company by the Underwriters through the Representatives expressly for use in the Registration Statement (or any amendment thereto), or in any preliminary prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement to any of the foregoing), consists exclusively of the following information appearing under the caption “Underwriting” in the Pre-Pricing Prospectus and the Prospectus: (i) the information regarding the concession and reallowance appearing in the first paragraph under the caption “Underwriting—Discounts” and (ii) the information regarding stabilization, syndicate covering transactions and penalty bids appearing under the caption “Underwriting—Stabilization” (but only insofar as such information concerns the Underwriters).

(c) Actions Against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder. Counsel to the indemnified parties shall be selected as follows: counsel to the Underwriters and the other indemnified parties referred to in Section 7(a) above shall be selected by Wells Fargo, counsel to the Trust, its trustees and other representatives and persons acting on the Trust’s behalf shall be selected by the Trustee, and counsel to the Company, its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying party be liable for the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for the Underwriters and the other indemnified parties referred to in Section 7(a) above, and the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for the Trust, its trustees and other representatives and persons acting on the Trust’s behalf or for the Company, its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, in each case in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No

30

indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 7 or Section 8 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Settlement Without Consent if Failure to Reimburse. 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 this Section 7, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 7(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

(e) Certain Conditions with Respect to Indemnification by the Trust. Notwithstanding the foregoing, the Trust shall not be obligated to make any payments to an indemnified party under this Section 7 until the earliest to occur of the following: (i) with respect to a final, nonappealable judgment of a court of competent jurisdiction or a settlement agreement, the Company has not paid such indemnified party the amount owed within 30 days of the due date under such judgment or settlement, (ii) with respect to expenses, the Company has not paid such indemnified party the amount owed within 30 days of submission by the indemnified party for reimbursement of such expenses or (iii) the Company shall become the subject of any bankruptcy or insolvency proceedings or publicly declares its inability to pay its debts as they become due.

(f) Other Agreements with Respect to Indemnification and Contribution. The provisions of this Section 7 and in Section 8 hereof shall not affect any agreements among the Company and the Trust with respect to indemnification of each other or contribution between themselves.

SECTION 8. Contribution. If the indemnification provided for in Section 7 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party under Section 7(a) or 7(b) in respect of any losses, liabilities, claims, damages or expenses, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Trust, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Agreement 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) above but also the relative fault of the Company and the Trust, on the one hand, and of the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company and the Trust, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of the Securities as set forth on such cover.

The relative fault of the Company and the Trust on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Trust on the one hand or by the Underwriters on the other hand and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

31

The Trust, the Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 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 which does not take account of the equitable considerations referred to above in this Section 8. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 8 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing for or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any 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 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

The Underwriters’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the number of Initial Securities set forth opposite their respective names in Exhibit A hereto and not joint.

For purposes of this Section 8, each affiliate of any Underwriter, each officer, director, employee, partner and member of any Underwriter or any such affiliate, and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each trustee of the Trust, director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company or the Trust, as applicable. The Underwriters’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the number of Initial Securities set forth opposite their respective names in Exhibit A hereto and not joint.

SECTION 9. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates signed by any officer of the Company or any of its subsidiaries (whether signed on behalf of such officer, the Company or such subsidiary) or signed by or on behalf of the Trust and delivered to the Representatives or counsel to the Underwriters, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, any officer, director, employee, partner, member or agent of any Underwriter or any person controlling any Underwriter, or by or on behalf of the Company, any officer, director or employee of the Company or any person controlling the Company, or signed by or on behalf of the Trust and shall survive delivery of and payment for the Securities.

SECTION 10. Termination of Agreement.

(a) Termination; General. The Representatives may terminate this Agreement, by notice to the Company and the Trust, at any time on or prior to Closing Date (and, if any Option Securities are to be purchased on an Option Closing Date which occurs after the Closing Date, the Representatives may terminate the obligations of the several Underwriters to purchase such Option Securities, by notice to the Company and the Trust at any time on or prior to such Option Closing Date) (i) if there has been, at any time on or after the date of this Agreement or since the respective dates as of which information is given in the General Disclosure Package or the Prospectus (in each case exclusive of any amendments or supplements thereto subsequent to the date of this Agreement), any material adverse change or any development that would be reasonably expected to result in a material adverse change in the condition (financial or other), results of operations, business, properties, the Underlying Properties, management or prospects of either the Trust or the Company and its subsidiaries taken as a whole, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any declaration of a national emergency or war by the United States, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions (including, without limitation, as a result of terrorist activities), in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if

32

(A) trading in any securities of the Company has been suspended or materially limited by the Commission or the NYSE, or (B) trading generally on the NYSE, the Nasdaq Global Select Market, the Nasdaq Global Market, the NYSE Amex, the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade has been suspended or limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by order of the Commission, FINRA or any other governmental authority, or (C) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or in Europe, or (iv) if a banking moratorium has been declared by either Federal or New York authorities or (v) if there shall have occurred, at any time on or after the date of this Agreement, any downgrading in the rating of any debt securities of or guaranteed by the Company by any “nationally recognized statistical rating organization” (as defined in Section 3(a)(62) of the 1934 Act) or any public announcement that any such organization has placed its rating on the Company or any such debt securities under surveillance or review or on a so-called “watch list” (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating) or any announcement by any such organization that the Company or any such debt securities has been placed on negative outlook.

(b) Liabilities. If this Agreement is terminated pursuant to this Section 10, such termination shall be without liability of any party to any other party except as provided in Section 5 hereof and except that Sections 1, 7, 8, 9, 12, 13, 14, 15, 16, 18, 19, 20 and 21 hereof shall survive such termination and remain in full force and effect.

SECTION 11. Default by One or More of the Underwriters or the Company.

(a) If one or more of the Underwriters shall fail at the Closing Date or an Option Closing Date to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(1) if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount of such Defaulted Securities in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters; or

(2) if the number of Defaulted Securities exceeds 10% of the number of Securities to be purchased on such date, this Agreement or, with respect to any Option Closing Date which occurs after the Closing Date, the obligation of the Underwriters to purchase and of the Company to sell the Option Securities that were to have been purchased and sold on such Option Closing Date, shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section 11(a) shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement or, in the case of an Option Closing Date which is after the Closing Date, which does not result in a termination of the obligations of the Underwriters to purchase and the Company to sell the relevant Option Securities, as the case may be, the Representatives shall have the right to postpone the Closing Date or the relevant Option Closing Date, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the General Disclosure Package or Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 11.

(b) If the Company fails at the Closing Date or an Option Closing Date to deliver and sell the Securities which it is obligated to deliver and sell under this Agreement by reason other than default by one or more of the Underwriters, the Representatives shall have the right, at their option, by notice from the Representatives to the Company, either (i) if such failure occurs prior to the Closing Date, to terminate this Agreement or, with respect to any Option Closing Date which occurs after the Closing Date, to terminate the obligation of the Underwriters to

33

purchase and of the Company to sell the Option Securities that were to have been purchased and sold on such Option Closing Date or (ii) to purchase the Securities which the Company has agreed to sell and deliver on such date in accordance with the terms hereof.

No action taken pursuant to this Section 11(b) shall relieve the Company from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement or, in the case of an Option Closing Date which is after the Closing Date, which does not result in a termination of the obligation of the Underwriters to purchase and the Company to sell the relevant Option Securities, as the case may be, the Representatives shall have the right to postpone the Closing Date or the relevant Option Closing Date, as the case may be, for a period not exceeding seven days in order to effect any required changes to the Registration Statement, the General Disclosure Package or the Prospectus or in any other documents or arrangements.

As Representatives of the several Underwriters

c/o Wells Fargo Securities, LLC

375 Park Avenue

Ladies and Gentlemen:

This agreement is being delivered to you in connection with the proposed Underwriting Agreement (the “Underwriting Agreement”) among PermRock Royalty Trust, a statutory trust organized under the laws of Delaware (the “Trust”), Boaz Energy II, LLC, a Delaware limited liability company (the “Company”), Wells Fargo Securities, LLC (“Wells Fargo”), Goldman Sachs & Co. LLC (“Goldman”) and UBS Securities LLC (“UBS”, and collectively with Wells Fargo and Goldman, the “Representatives”), as representatives of a group of underwriters (the “Underwriters”) and the other parties thereto (if any), relating to a proposed underwritten public offering of trust units of beneficial interest (“Trust Units”) of the Trust by the Company.

In order to induce you and the other Underwriters to enter into the Underwriting Agreement, and in light of the benefits that the offering of the Trust Units will confer upon the undersigned in its capacity as a securityholder and/or an officer or director of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned agrees with each Underwriter that, during the period beginning on and including the date of the Underwriting Agreement through and including the date that is the 180th day after the date of the Underwriting Agreement (such period, the “Lock-Up Period”), the undersigned will not, without the prior written consent of the Representatives, directly or indirectly:

(i) 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 any Trust Units or other capital stock or any securities convertible into or exercisable or exchangeable for Trust Units or other capital stock, whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition, or

(ii) enter into any swap or other agreement, arrangement or transaction that transfers to another, in whole or in part, directly or indirectly, any of the economic consequence of ownership of any Trust Units or other capital stock or any securities convertible into or exercisable or exchangeable for any Trust Units or other capital stock,

whether any transaction described in clause (i) or (ii) above is to be settled by delivery of Trust Units, other capital stock, other securities, in cash or otherwise, or publicly announce any intention to do any of the foregoing.

D-1

Notwithstanding the provisions set forth in the immediately preceding paragraph, the undersigned may, without the prior written consent of the Representatives, transfer any Trust Units or other capital stock or any securities convertible into or exchangeable or exercisable for Trust Units or other capital stock:

(1) if the undersigned is a natural person, as a bona fide gift or gifts or by will, by intestate succession or pursuant to a so-called “living trust” or other revocable trust established to provide for the disposition of property on the undersigned’s death, in each case to any member of the immediate family (as defined below) of the undersigned or to a trust the beneficiaries of which are exclusively the undersigned or members of the undersigned’s immediate family, or as a bona fide gift or gifts to a charity or educational institution, and

(2) if the undersigned is a partnership or a limited liability company, to a partner or member, as the case may be, of such partnership or limited liability company if, in any such case, such transfer is not for value.

provided, however, that in the case of any transfer described in clause (1) or (2) above, it shall be a condition to the transfer that (A) the transferee executes and delivers to the Representatives acting on behalf of the Underwriters, not later than one business day prior to such transfer, a written agreement, in substantially the form of this agreement (it being understood that any references to “immediate family” in the agreement executed by such transferee shall expressly refer only to the immediate family of the undersigned and not to the immediate family of the transferee) and otherwise satisfactory in form and substance to the Representatives, (B) in the case of a transfer pursuant to clause (1) above, if the undersigned is required to file a report under Section 16(a) of the Securities Exchange Act of 1934, as amended (the “1934 Act”), reporting a reduction in beneficial ownership of Trust Units or any securities convertible into or exercisable or exchangeable for Trust Units by the undersigned during the Lock-Up Period, the undersigned shall include a statement in such report to the effect that such transfer is not a transfer for value and that such transfer is being made as a gift, by will or intestate succession or pursuant to a so-called “living trust” or other revocable trust established to provide for the disposition of property on the undersigned’s death, as the case may be, (C) in the case of a transfer pursuant to clause (2) above, no filing under Section 16(a) of the 1934 Act reporting a reduction in beneficial ownership of Trust Units or other capital stock or any securities convertible into or exercisable or exchangeable for Trust Units or other capital stock shall be required to be made during the Lock-Up Period and (D) in the case of a transfer pursuant to clause (1) or (2) above, no voluntary filing with the Securities and Exchange Commission or other public report, filing or announcement shall be made in respect of such transfer during this Lock-Up Period. For purposes of this paragraph, “immediate family” shall mean any relationship by blood, marriage or adoption not more remote than the first cousin.

Prior to engaging in any transaction or taking any other action that is subject to the restrictions imposed by clauses (i) and (ii) above at any time during the Lock-Up Period, the undersigned will give notice thereof to the Company and the Trust and will not consummate such transaction or take any such action unless it has received written confirmation from the Company and the Trust that the Lock-Up Period has expired.

The undersigned further agrees that (i) it will not, during the Lock-Up Period, make any demand for or exercise any right with respect to the registration under the Securities Act of 1933, as amended (the “1933 Act”), of any Trust Units or other capital stock or any securities convertible into or exercisable or exchangeable for Trust Units or other capital stock, and (ii) the Trust may, with respect to any Trust Units or other capital stock or any securities convertible into or exercisable or exchangeable for Trust Units or other capital stock owned or held (of record or beneficially) by the undersigned, cause the transfer agent or other registrar to enter stop transfer instructions and implement stop transfer procedures with respect to such securities during the Lock-Up Period.

The undersigned hereby waives any and all notice requirements and rights with respect to the registration of any securities pursuant to any agreement, instrument, understanding or otherwise, including any registration rights agreement or similar agreement, to which the undersigned is a party or under which the undersigned is entitled to any right or benefit and any tag-along rights, co-sale rights or other rights to have any securities (debt or equity) included in the offering contemplated by this agreement or sold in connection with the sale of Securities pursuant to the Underwriting Agreement, provided that such waiver shall apply only to the public offering of Trust Units pursuant to the Underwriting Agreement and each registration statement filed under the 1933 Act in connection therewith.

D-2

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this agreement and that this agreement has been duly authorized (if applicable), executed and delivered by the undersigned and is a valid and binding agreement of the undersigned. This agreement and all authority herein conferred are irrevocable and shall survive the death or incapacity of the undersigned (if a natural person) and shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned.

If the Underwriting Agreement is not executed by the parties thereto prior to [ · ], [ · ], or if the Underwriting Agreement shall be terminated prior to the delivery of the Securities thereunder, this agreement shall automatically terminate and become null and void.

The undersigned acknowledges and agrees that whether or not any public offering of Trust Units actually occurs depends on a number of factors, including market conditions.

THE AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
