existing Subject Wells on such Lease (subject to increases or reductions proportionate to the Enduro Texas’s contributing interest of the Lease in relation to each spacing unit of any such future Subject Well); and (ii) the merger whereby Enduro Texas merged with and into the Trust (the “Trust Merger”) was sufficient to cause all of the rights of Enduro Texas in the Net Profits Interest to vest in the Trust as successor to Enduro Texas. From and after the Trust Merger, the Trust’s net revenue interest with respect to each Subject Interest was, at the date of the Conveyance, no less than the net revenue interest set forth in the Conveyance and its working interest with respect to each Subject Interest was, at the date of the Conveyance, no greater than the working interest set forth in the Conveyance (except for circumstances which resulted in a proportionate increase in the Trust’s corresponding net revenue interest for such Subject Interests).

All contracts, agreements or underlying leases, which comprise a portion of the Subject Interests and which individually or in the aggregate are material to the Subject Interests, are in full force and effect, Enduro Operating has paid all rents and other charges to the extent due and payable thereunder, is not in default under any of such underlying contracts, agreements or leases, has received no notice of default from any other party thereto and knows of no material default by any other party thereto. The working interests in oil, gas and mineral leases or mineral interests that constitute a portion of the Subject Interests held by Enduro Operating reflect in all material respects the right of Enduro Operating to explore or receive production from such Subject Interests and the care taken by Enduro Operating with respect to acquiring or otherwise procuring such leases or mineral interests was generally consistent with standard industry practices for acquiring or procuring leases and interests therein to explore such for hydrocarbons.

or in the aggregate, a Material Adverse Effect; Enduro Operating has fulfilled and performed all its material obligations with respect to such rights-of-way, and no event has occurred that allows, or after notice or lapse of time would allow, revocation or termination thereof or would result in any impairment of the rights of Enduro Operating with respect to such rights-of-way, except for such revocations, terminations and impairments that could not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect; and none of such rights-of-way contains any restriction that is materially burdensome to Enduro Operating.

(cc) Permits. The Company and each of its subsidiaries have such permits, licenses, patents, franchises, certificates of need and other approvals, consents or authorizations of governmental or regulatory authorities (“Permits”) as are necessary under applicable law to own their properties and conduct their businesses in the manner described in the Registration Statement, the Pricing Disclosure Package and the Prospectus, except for any of the foregoing that could not, in the aggregate, reasonably be expected to have a Material Adverse Effect; each of the Company and its subsidiaries has fulfilled and performed all of its obligations with respect to the Permits, and no event has occurred that allows, or after notice or lapse of time would allow, revocation or termination thereof or results in any other impairment of the rights of the holder or any such Permits, except for any of the foregoing that could not reasonably be expected to have a Material Adverse Effect.

(ee) Certain Relationships and Related Transactions. Except as set forth in the Pricing Disclosure Package and the Prospectus, there are no transactions with “affiliates” (as defined in Rule 405 promulgated under the Securities Act) of the Company or any member of the Company (whether or not an affiliate) that are required by the Securities Act to be disclosed in the Registration Statement, the Pricing Disclosure Package or the Prospectus.

3. Purchase of the Units by the Underwriters. On the basis of the representations, warranties and covenants contained in, and subject to the terms and conditions of, this Agreement, the Company agrees to sell the Firm Units to the several Underwriters, and each of the Underwriters, severally and not jointly, agrees to purchase the number of Firm Units set forth opposite that Underwriter’s name in Schedule 1 hereto. The respective purchase obligations of the Underwriters with respect to the Firm Units shall be rounded among the Underwriters to avoid fractional units, as the Representatives may determine.

Such option is exercisable in the event that the Underwriters sell more than the number of Firm Units in the offering and as set forth in Section 5 hereof. Each Underwriter agrees, severally and not jointly, to purchase the number of Option Units (subject to such adjustments to eliminate fractional units as the Representatives may determine) that bears the same proportion to the total number of Option Units to be sold on such Delivery Date as the number of Firm Units set forth in Schedule 1 hereto opposite the name of such Underwriter bears to the total number Firm Units.

The purchase price payable by the Underwriters for both the Firm Units and any Option Units purchased by the Underwriters shall be $13.296 per unit less an amount equal to any distributions declared by the Trust and payable on each Firm Unit but not on each Option Unit.

The Company is not obligated to deliver any of the Firm Units or Option Units to be delivered on the applicable Delivery Date, except upon payment for all such Trust Units to be purchased on such Delivery Date as provided herein.

4. Offering of Units by the Underwriters. Upon authorization by the Representatives of the release of the Firm Units, the several Underwriters propose to offer the Firm Units for sale upon the terms and conditions to be set forth in the Prospectus.

Delivery of and payment for the Firm Units shall be made at 10:00 A.M., New York City time, on the third full business day following the date of this Agreement or at such other date or place as shall be determined by agreement between the Representatives and the Trust. This date and time are sometimes referred to as the “Initial Delivery Date.” Delivery of the Firm Units shall be made to the Representatives for the account of each Underwriter against payment by the several Underwriters through the Representatives and of the respective aggregate purchase prices of the Firm Units being sold by the Company to or upon the order of the Company of the purchase price by wire transfer in immediately available funds to the accounts specified by the Company. Time shall be of the essence, and delivery at the time and place specified pursuant to this Agreement is a further condition of the obligation of each Underwriter hereunder. The Company shall deliver the Firm Units through the facilities of DTC unless the Representatives shall otherwise instruct.

The option granted in Section 3 will expire 30 days after the date of this Agreement and may be exercised in whole or from time to time in part by written notice being given to the Company by the Representatives; provided that if such date falls on a day that is not a business day, the option granted in Section 3 will expire on the next succeeding business day. Such notice shall set forth the aggregate number of Option Units as to which the option is being exercised, the names in which the Option Units are to be registered, the denominations in which the Option Units are to be issued and the date and time, as determined by the Representatives, when the Option Units are to be delivered; provided, however, that this date and time shall not be earlier than the Initial Delivery Date nor earlier than the second business day after the date on which the option shall have been exercised nor later than the fifth business day after the date on which the option shall have been exercised. Each date and time any Option Units are delivered is sometimes referred to as an “Option Units Delivery Date,” and the Initial Delivery Date and any Option Units Delivery Date are sometimes each referred to as a “Delivery Date.”

Delivery of the Option Units by the Company and payment for the Option Units by the several Underwriters through the Representatives shall be made at 10:00 A.M., New York City time, on the date specified in the corresponding notice described in the preceding paragraph

or at such other date or place as shall be determined by agreement between the Representatives and the Company. On the Option Units Delivery Date, the Company shall deliver or cause to be delivered the Option Units to the Representatives for the account of each Underwriter against payment by the several Underwriters through the Representatives and of the respective aggregate purchase prices of the Option Units being sold by the Company to or upon the order of the Company of the purchase price by wire transfer in immediately available funds to the accounts specified by the Company. Time shall be of the essence, and delivery at the time and place specified pursuant to this Agreement is a further condition of the obligation of each Underwriter hereunder.

(a) The Company and the Trust each hereby agrees to indemnify and hold harmless each Underwriter, its directors, officers, employees, agents and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and any “affiliate” (within the meaning of Rule 405 under the Securities Act) of such Underwriter participating in the offering of the Units, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Units), to which that Underwriter, affiliate, director, officer, employee, agent or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in (A) any Preliminary Prospectus, the Registration Statement, the Prospectus or in any amendment or supplement thereto, (B) any Issuer Free Writing Prospectus or in any amendment or supplement thereto, (C) any “issuer information” (as defined in Rule 433 under the Securities Act) in any “free writing prospectus” (as defined in Rule 405 under the Securities Act) used or referred to by such Underwriter with the prior consent of the Trust and the Company (any such issuer information with respect to whose use the Trust and the Company has given its consent, “Permitted Issuer Information”), (D) any materials or information provided to investors by, or with the approval of, the Trust and the Company in connection with the marketing of the offering of the Units, including any “road show” (as defined in Rule 433 under the Securities Act) not constituting an Issuer Free Writing Prospectus (“Marketing Materials”) or (E) any Blue Sky application or other document prepared or executed by the Company or the Trust (or based upon any written information furnished by the Company or the Trust for use therein) specifically for the purpose of qualifying any or all of the Units under the securities laws of any state or other jurisdiction (any such application, document or information being hereinafter called a “Blue Sky Application”) or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Permitted Issuer Information, any Marketing Materials or any Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein (except in the case of the Registration Statement, in light of the circumstances under which they were made) not misleading, and shall reimburse each Underwriter and each such affiliate, director, officer, employee, agent or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Underwriter, affiliate, director, officer, employee, agent or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that neither the Company nor the Trust shall be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any such amendment or supplement thereto or in any Permitted Issuer Information, any Marketing Materials or any Blue Sky Application, in reliance upon and in conformity with written information concerning such Underwriter furnished to the Company or the Trust through the Representatives by or on behalf of any Underwriter specifically for inclusion therein, which information consists solely of the information specified in Section 10(f). The foregoing indemnity agreement is in addition to any liability which the Company or the Trust may otherwise have to any Underwriter or to any affiliate, director, officer, employee, agent or controlling person of that Underwriter.

(b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Trust, the Company, their respective trustees, directors, officers and employees, and each person, if any, who controls the Trust or the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Trust, the Company or any such trustee, director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Marketing Materials or Blue Sky Application, or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Marketing Materials or Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein (except in the case of the Registration Statement, in light of the circumstances under which they were made) not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Underwriter furnished to the Company or the Trust through the Representatives by or on behalf of that Underwriter specifically for inclusion therein, which information is limited to the information set forth in Section 10(f). The foregoing indemnity agreement is in addition to any liability that any Underwriter may otherwise have to the Trust, the Company or any such trustee, director, officer, employee or controlling person.

(c) Promptly after receipt by an indemnified party under this Section 10 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 10, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 10 except to the extent it has been materially prejudiced (through the forfeiture of substantive rights and defenses) by such failure and, provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 10. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 10 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation;

provided, however, that the indemnified party shall have the right to employ counsel to represent jointly the indemnified party and those other indemnified parties and their respective trustees, directors, officers, employees, agents and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought under this Section 10 if (i) the indemnified party and the indemnifying party shall have so mutually agreed; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party and its trustees, directors, officers, employees, agents and controlling persons shall have reasonably concluded that there may be legal defenses available to them that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnified parties or their respective trustees, directors, officers, employees, agents or controlling persons, on the one hand, and the indemnifying party, on the other hand, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the indemnifying party. No indemnifying party shall (x) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and 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, or (y) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d) Notwithstanding the foregoing, the Trust shall not be obligated to make any payments to an indemnified party under this Section 10 until the earlier to occur of the following: (a) 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.

(e) If the indemnification provided for in this Section 10 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 10(a) or 10(b), or in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect

thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company and the Trust, on the one hand, and the Underwriters, on the other, from the offering of the Units or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Trust, on the one hand, and the Underwriters, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, 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, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Units purchased under this Agreement (before deducting expenses) received by the Company, as set forth in the table on the cover page of the Prospectus, on the one hand, and the total underwriting discounts and commissions received by the Underwriters with respect to the Units purchased under this Agreement, as set forth in the table on the cover page of the Prospectus, on the other hand. The relative fault shall be determined by reference to whether the 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 Trust, the Company or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Trust, the Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 10(e) were to be 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 into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 10(e) shall be deemed to include, for purposes of this Section 10(e), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 10(e), in no event shall an Underwriter be required to contribute any amount in excess of the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Units 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 as provided in this Section 10(e) are several in proportion to their respective underwriting obligations and not joint.

(f) The Underwriters severally confirm and the Trust and the Company acknowledge and agree that (i) the second paragraph under “Commissions and Expenses” and (ii) paragraphs under “Stabilization, Short Positions and Penalty Bids,” each under the caption “Underwriting” in the most recent Preliminary Prospectus and Prospectus are correct and constitute the only information concerning such Underwriters furnished in writing to the Company by or on behalf of the Underwriters specifically for inclusion in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Marketing Materials.

11. Defaulting Underwriters.

(a) If, on any Delivery Date, any Underwriter defaults in its obligations to purchase the Units that it has agreed to purchase under this Agreement, the remaining non-defaulting Underwriters may in their discretion arrange for the purchase of such Units by the non-defaulting Underwriters or other persons satisfactory to the Trust and 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 Units, then the Trust and 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 Units on such terms. In the event that within the respective prescribed periods, the non-defaulting Underwriters notify the Trust and the Company that they have so arranged for the purchase of such Units, or the Trust and the Company notifies the non-defaulting Underwriters that they have so arranged for the purchase of such Units, either the non-defaulting Underwriters or the Company may postpone such Delivery Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Trust, counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement, and the Trust and the Company agree to promptly prepare any amendment or supplement to the Registration Statement, the Prospectus or in any such other document or arrangement that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 hereto that, pursuant to this Section 11, purchases Units that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Units of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Trust and the Company as provided in paragraph (a) above, the total number of Units that remains unpurchased does not exceed one-eleventh of the total number of all the Units, then the Trust and the Company shall have the right to require each non-defaulting Underwriter to purchase the total number of Units that such Underwriter agreed to purchase hereunder plus such Underwriter’s pro rata share (based on the total number of Units that such Underwriter agreed to purchase hereunder) of the Units of such defaulting Underwriter or Underwriters for which such arrangements have not been made; provided that the non-defaulting Underwriters shall not be obligated to purchase more than 110% of the total number of Units that it agreed to purchase on such Delivery Date pursuant to the terms of Section 3.

(c) If, after giving effect to any arrangements for the purchase of the Units of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Trust and the Company as provided in paragraph (a) above, the total number of shares of Units that remains unpurchased exceeds one-eleventh of the total number of Units, or if the Trust and the Company shall not exercise the right described in paragraph (b) above,

then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters or the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 11 shall be without liability on the part of the Trust or the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Sections 8 and 13 and except that the provisions of Section 10 shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company or any non-defaulting Underwriter for damages caused by its default.

12. Termination. The obligations of the Underwriters hereunder may be terminated by the Representatives by notice given to and received by the Company and the Trust prior to delivery of and payment for the Firm Units if, prior to that time, any of the events described in Sections 9(p) and 9(q) shall have occurred or if the Underwriters shall decline to purchase the Units for any reason permitted under this Agreement.

13. Reimbursement of Underwriters’ Expenses. If (a) the Company shall fail to tender the Units for delivery to the Underwriters for any reason, or (b) the Underwriters shall decline to purchase the Units for any reason permitted under this Agreement, the Company will reimburse the Underwriters for all reasonable out-of-pocket expenses (including fees and disbursements of counsel for the Underwriters) incurred by the Underwriters in connection with this Agreement and the proposed purchase of the Units, and upon demand the Company shall pay the full amount thereof to the Representatives. If this Agreement is terminated pursuant to Section 11 by reason of the default of one or more Underwriters, the Company shall not be obligated to reimburse any defaulting Underwriter on account of those expenses.

14. Research Analyst Independence. Each of the Company and the Trust acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company, the Trust and/or the offering that differ from the views of their respective investment banking divisions. Each of the Company and the Trust hereby waives and releases, to the fullest extent permitted by law, any claims that the Company or the Trust, as the case may be, may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company or the Trust by such Underwriters’ investment banking divisions. Each of the Company and the Trust acknowledges that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.

15. No Fiduciary Duty. The Company and the Trust each acknowledges and agrees that in connection with this offering and sale of the Units or any other services the Underwriters may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters: (a) no fiduciary or agency relationship between the Company, the Trust and any other person, on the one hand, and the Underwriters, on the other, exists; (b) the Underwriters are not acting as advisors, expert or otherwise, to either the Company or the Trust, including, without limitation, with respect to the determination of the public offering price of the Units, and such relationship between the Company and the Trust, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arms-length negotiations; (c) any duties and obligations that the Underwriters may have to the Company or the Trust shall be limited to those duties and obligations specifically stated herein; and (d) the Underwriters and their respective affiliates may have interests that differ from those of the Company and the Trust. The Company and the Trust each hereby waives any claims that the Company or the Trust may have against the Underwriters with respect to any breach of fiduciary duty in connection with this offering.

16. Notices, etc. All statements, requests, notices and agreements hereunder shall be in writing, and:

(a) if to the Underwriters, shall be delivered or sent by mail or facsimile transmission to Barclays Capital Inc., 745 Seventh Avenue, New York, New York 10019, Attention: Syndicate Registration (Fax: 646-834-8133)), with a copy, in the case of any notice pursuant to Section 10(c), to the Director of Litigation, Office of the General Counsel, Barclays Capital Inc., 200 Park Avenue, New York, New York 10166;

This Agreement and the terms and provisions hereof are for the sole benefit of only those persons, except that (a) the representations, warranties, indemnities and agreements of the Company and the Trust contained in this Agreement shall also be deemed to be for the benefit of the directors, officers, employees and agents of the Underwriters and each person or persons, if any, who control any Underwriter within the meaning of Section 15 of the Securities Act, (b) the representations and warranties of the Company contained in this Agreement, including those set forth in Section 1 hereof, shall also be deemed to be for the benefit of the Trustee, and (c) the indemnity agreement of the Underwriters contained in Section 10(c) of this Agreement shall be

deemed to be for the benefit of the trustees of the Trust, the directors of the Company or the Trust, the officers of the Company or the Trustee who have signed the Registration Statement and any person controlling the Company or the Trust within the meaning of Section 15 of the Securities Act. Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in this Section 17, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. Nothing in this Agreement shall affect or modify in any respect the provisions of Section 6 of the Registration Rights Agreement dated as of November 8, 2011 between the Company and the Trust.

18. Survival. The respective indemnities, representations, warranties and agreements of the Company, the Trust and the Underwriters contained in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall survive the delivery of and payment for the Units and shall remain in full force and effect, regardless of any investigation made by or on behalf of any of them or any person controlling any of them.

19. Definition of the Terms “Business Day”, “Affiliate” and “Subsidiary”. For purposes of this Agreement, (a) “business day” means each Monday, Tuesday, Wednesday, Thursday or Friday that is not a day on which banking institutions in New York are generally authorized or obligated by law or executive order to close and (b) “affiliate” and “subsidiary” shall have the meanings set forth in Rule 405 under the Securities Act.

FORM OF LOCK-UP LETTER AGREEMENT

BARCLAYS CAPITAL INC.

As Representative of the several

Underwriters named in Schedule 1,

c/o Barclays Capital Inc.

200 Park Avenue

New York, New York 10166

Ladies and Gentlemen:

The undersigned understands that you and certain other firms (the “Underwriters”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) providing for the purchase by the Underwriters of trust units (the “Units”) of beneficial interest of Enduro Royalty Trust, a Delaware Statutory Trust (the “Trust”), and that the Underwriters propose to reoffer the Units to the public (the “Offering”).

In consideration of the execution of the Underwriting Agreement by the Underwriters, and for other good and valuable consideration, the undersigned hereby irrevocably agrees that, without the prior written consent of Barclays Capital Inc., on behalf of the Underwriters, the undersigned will not, directly or indirectly, (1) offer for sale, sell, pledge or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any Units (including, without limitation, Units that may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and Units that may be issued upon exercise of any options or warrants) or securities convertible into or exercisable or exchangeable for Units, (2) enter into any swap or other derivative transaction that transfers to another, in whole or in part, any of the economic consequences of ownership of Units, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Units or other securities, in cash or otherwise, (3) make any demand for or exercise any right or file or cause to be filed a registration statement, including any amendments thereto, with respect to the registration of any Units or securities convertible, exercisable or exchangeable into Units or any other securities of the Trust or (4) publicly disclose the intention to do any of the foregoing, for a period commencing on the date hereof and ending on the 60th day after the date of the Prospectus relating to the Offering (such 60-day period, the “Lock-Up Period”).

Notwithstanding the foregoing, if (1) during the last 17 days of the Lock-Up Period, the Trust issues an earnings release or material news or a material event relating to the Trust occurs or (2) prior to the expiration of the Lock-Up Period, the Trust announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period, then the restrictions imposed by this Lock-Up Letter Agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the announcement of the material news or the occurrence of the material event, unless such extension is waived by Barclays Capital Inc. in writing.

In furtherance of the foregoing, the Trust and its transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Letter Agreement.

It is understood that, if the Trust notifies the Underwriters that it does not intend to proceed with the Offering, 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 Units, the undersigned will be released from its obligations under this Lock-Up Letter Agreement.

The undersigned understands that the Company and the Underwriters will proceed with the Offering in reliance on this Lock-Up Letter Agreement.

Whether or not the Offering actually occurs depends on a number of factors, including market conditions. Any Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation among the Trust, Enduro Resource Partners LLC and the Underwriters.

[Signature page follows]

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Letter Agreement and that, upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof. Any obligations of the undersigned shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned.

FORM OF OPINION OF LATHAM & WATKINS LLP

1. The Company is a limited liability company duly formed under the laws of the State of Delaware with limited liability company power and authority to own its properties and to conduct its business as described in the Registration Statement, the Pricing Disclosure Package and the Prospectus. With your consent, based solely on certificates from public officials, we confirm that the Company is validly existing and in good standing under the laws of the State of Delaware.

2. The Company has limited liability company power and authority to enter into the Underwriting Agreement. The execution, delivery and performance of the Underwriting Agreement has been duly authorized by all necessary limited liability company action of the Company; and the Underwriting Agreement has been duly executed and delivered by the Company.

3. The execution and delivery of the Underwriting Agreement, the performance of the obligations contemplated by the Underwriting Agreement and the sale of the Units by the Company do not on the date hereof:

violate the Organizational Documents of the Company;

ii.

result in the breach of or a default under any of the Specified Agreements set forth in Schedule 5 to this Agreement;

iii.

violate any federal or Texas statute, rule or regulation applicable to the Company or the Trust;

iv.

result in the creation of any security interest in, or lien upon any property (including, without limitation, the Subject Interests) or assets of the Trust under any of the Specified Agreements; or

require any consents, approvals, or authorizations to be obtained by the Company or the Trust from, or any registrations, declarations or filings to be made by the Company or the Trust with, any governmental authority under any federal or Texas statute, rule or regulation applicable to the Company or the Trust or under the Delaware LLC Act, on or prior to the date hereof that have not been obtained or made.

4. The Registration Statement has become effective under the Act. To the best of our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued under the Act and no proceedings therefor have been initiated or threatened by the Commission. The most recent Preliminary Prospectus has been filed in accordance with Rule 424(b) under the Act and the Prospectus has been filed in accordance with Rule 424(b) and 430B under the Act.

B-1A-1

5. The Registration Statement, on the latest Effective Date, and the Prospectus, as of its date and the date hereof, each appeared on their face to be appropriately responsive in all material respects to the requirements of the Act; it being understood, however, that we express no view with respect to Regulation S-T or oil and gas reserves data or reports, financial statements, schedules, or other financial data, included in or omitted from, the Registration Statement or the Prospectus. For purposes of this paragraph, we have assumed that the statements made in the Registration Statement and the Prospectus are correct and complete.

6. The statements in the Registration Statement, Preliminary Prospectus and the Prospectus under the captions “Summary,” “The Trust,” “Description of the Trust Agreement,” and “Description of the Trust Units,” insofar as they purport to constitute a summary of the terms of the Trust Units, and under the captions “Summary,” “The Trust,” “Description of the Trust Agreement,” and “Description of the Trust Units,” insofar as they purport to describe or summarize certain provisions of the documents or Texas or U.S. federal laws referred to therein, are accurate descriptions or summaries in all material respects. The statements in the Trust’s Annual Report on Form 10-K for the year ended December 31, 2012 under the caption “Part 1. Item 1. Business–Computation of Net Profits–Net Profits Interest,” insofar as it purports to describe or summarize certain provisions of the documents or Texas or U.S. federal laws referred to therein, is an accurate description or summary in all material respects.

7. The Company is not, and immediately after giving effect to the sale of the Units in accordance with the Underwriting Agreement and the application of the proceeds as described in the Prospectus under the caption “Use of Proceeds,” will not be required to be, registered as an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

8. The Conveyance was in a form legally sufficient to convey all right, title and interest of Enduro Operating LLC in and to the Net Profits Interest to the grantee thereunder and complied with the recording acts of the State of Texas; the recording of the Conveyance and the Conveyance Supplement in the appropriate real property records in each county in the State of Texas where the Subject Interests (as defined in the Conveyance) are located caused the Net Profits Interest to constitute a fully conveyed and vested real property interest and is sufficient to provide the grantee thereunder the protections afforded under the recording acts of the State of Texas against purchasers or creditors of Enduro Operating LLC or Enduro Texas LLC subsequently acquiring interests in the Subject Interests, and such purchasers and creditors of Enduro Operating LLC and Enduro Texas LLC have been deemed to purchase with notice of, and subject to, such Net Profits Interest.

9. Upon indication by book entry that the Units listed on Schedule 1 to the Underwriting Agreement have been credited to a securities account maintained by the several Underwriters at The Depository Trust Company (“DTC”) and payment therefor in accordance with the Underwriting Agreement, the several Underwriters will acquire a security entitlement with respect to such Units and, under the New York UCC, an action based on an adverse claim to the Units, whether framed in conversion, replevin, constructive trust, equitable lien or other theory may not be asserted against the several Underwriters.

B-1A-2

Such counsel shall state that they have reviewed the Registration Statement, the Pricing Disclosure Package and the Prospectus and have participated in conferences with officers and other representatives of the Company and the Trust, the independent registered public accounting firm of the Trust and the Company and representatives of the Underwriters, at which the contents of the Registration Statement, the Pricing Disclosure Package and the Prospectus and related matters were discussed, and although such counsel has not independently verified, is not passing upon, and is not assuming any responsibility for the accuracy, completeness or fairness of the statements contained in, the Registration Statement, the Pricing Disclosure Package and the Prospectus (except to the extent specified in the foregoing opinions), based on the foregoing, no facts have come to such counsel’s attention that lead such counsel to believe that:

(a) the Registration Statement, at the latest Effective Date, 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;

(b) the Pricing Disclosure Package, as of the Applicable Time, contained 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

(c) the Prospectus, as of its date or as of the Closing Date or the Additional Closing Date, contained or contains 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 such counsel expresses no statement or belief with respect to (a) the financial statements and related schedules, including the notes thereto and the independent public accounting firm’s report thereon, (b) the oil and gas reserve data or (c) other financial data contained therein or omitted therefrom.

In rendering such opinion, such counsel may state that its opinion is limited to matters governed by the federal laws of the United States of America, the laws of the State of New York, the State of Texas and the State of Delaware and that such counsel is not admitted in the State of Delaware.

EXHIBIT B-1B

FORM OF TAX OPINION OF LATHAM & WATKINS LLP

Based on such facts and subject to the qualifications, assumptions and limitations set forth in the opinion and in the Registration Statement, the Pricing Disclosure Package and the Prospectus, our opinion that is filed as an exhibit to the Current Report on Form 8-K to be filed on the Initial Delivery Date is confirmed, and the Underwriters may rely upon such opinion as if it were addressed to them.

B-1B-1

EXHIBIT B-2

FORM OF OPINION OF GORDON, ARATA, MCCOLLAM, DUPLANTIS & EAGAN, LLC

1. Assuming that neither the Trust nor the Trustee is otherwise transacting business in, or qualified to do business in, Louisiana, (a) the Trustee is not required to qualify with the Louisiana Secretary of State to transact business, or to appoint an agent for service of process, in the State of Louisiana solely as a result of the activities of the Trustee authorized pursuant to the Amended Trust Agreement, (b) the activities of the Trustee will not require the appointment of an ancillary trustee in the State of Louisiana and (c) the Trust is not required to qualify with the Louisiana Secretary of State to transact business in the State of Louisiana, or to appoint an agent for service of process in the State of Louisiana, solely as a result of the conveyance of the Net Profits Interest under the Conveyance and the Conveyance Supplement.

2. The Conveyance, as amended and supplemented by the Conveyance Supplement, constitutes a valid and binding agreement of Enduro Operating under the laws of State of Louisiana, enforceable against Enduro Operating in accordance with its terms. The Conveyance and the Conveyance Supplement were, as of the date of the Conveyance Supplement, collectively adequate and sufficient under the laws of the State of Louisiana to transfer, in favor of the Trustee, title to that portion of the Net Profits Interest constituting immovable property that is located in the State of Louisiana and is accurately and specifically described therein as being conveyed thereby. Each of the Conveyance and the Conveyance Supplement was, as of the date of the Conveyance Supplement, in sufficient form for filing for registry in the conveyance records of each Louisiana parish where any portion of any Lease is located and, for purposes of Louisiana’s law of registry, shall have effect against third persons from the time it was filed for registry in such conveyance records.

3. Under article 171 of the Louisiana Mineral Code, “[a] co-owner of the lessee’s interest in a mineral lease may create a dependent right such as an overriding royalty, production payment, net profits interest, or other non-operating interest out of his undivided interest without the consent of his co-owner” and “may also transfer all or part of his undivided interest.” Article 16 of the Louisiana Mineral Code provides that the mineral rights that may be created by the landowner include the mineral lease and are real rights, and article 17 of the Louisiana Mineral Code provides that a mineral right is an incorporeal immovable. Further, in an opinion decided before the Louisiana Mineral Code was enacted in 1974, the federal Fifth Circuit held that a net profits interest in a Louisiana mineral lease was a royalty interest subject to Louisiana’s severance tax. See Louisiana Land & Expl. Co. v. Donnelly, 394 F.2d 273 (5th Cir. 1968). Based on the foregoing, it is reasonable to conclude that a Louisiana court would classify the portion of the Net Profits Interest affecting Leases located in the State of Louisiana as a real right and an incorporeal immovable under Louisiana law.

4. A beneficial owner of a Unit of the Trust will not, solely by virtue of said ownership, be subject to personal liability under the laws of the State of Louisiana for any activities of the Trustee that are both authorized under the Amended Trust Agreement and described in the Registration Statement, the Preliminary Prospectus and the Prospectus.

B-2-1

In rendering such opinion, such counsel may (i) rely in respect of matters of fact upon certificates of officers and other employees of the Company and the Trustee and upon information obtained from public officials, (ii) assume that all documents submitted to them as originals are authentic, that all copies submitted to them conform to the originals thereof, and that the signatures on all documents examined by them are genuine, (iii) state that their opinion is limited to the laws of the State of Louisiana and (iv) 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 tax statutes to which the Company or the Trust may be subject.

EXHIBIT B-3

FORM OF OPINION OF HINKLE, HENSLEY, SHANOR & MARTIN, L.L.P.

1. Neither the Trust nor the Trustee is required to qualify to transact business or appoint an agent for service of process in the State of New Mexico as a result of the ownership, operation or activities of the Trust or the Trustee with respect to the Trust (as all such activities are described in the Registration Statement, the Pricing Disclosure Package and the Prospectus), and such activities of the Trustee pursuant to the Trust Agreement will not require the appointment of an ancillary trustee in the State of New Mexico.

2. The Conveyance, as amended by the Conveyance Supplement, constitutes a valid and binding agreement of Enduro Operating and the Trust under the laws of the State of New Mexico, enforceable against Enduro Operating and the Trust in accordance with its terms, subject to applicable 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); the Conveyance and the Conveyance Supplement are adequate and sufficient under the laws of the State of New Mexico to transfer title to the Net Profits Interest to the Trust and each complies with the laws of the State of New Mexico relating to recording and filing laws and regulations; the recording of the Conveyance and the Conveyance Supplement in the appropriate real property records in each county in the State of New Mexico where the Subject Interests (as defined in the Conveyance) are located has caused the Conveyance and the Conveyance Supplement to constitute a fully conveyed and vested real property interest and is sufficient to provide the Trust the protections afforded under the recordation laws of the State of New Mexico against purchasers or creditors of Enduro Operating or the Trust subsequently acquiring interests in the Subject Interests, and such purchasers and creditors of Enduro Operating and the Trust will be deemed to purchase with notice of, and subject to, such Net Profits Interest.

3. A beneficial owner of a Unit of the Trust will not be subject to personal liability under the laws of the State of New Mexico solely by virtue of said ownership.

4. Under the Bankruptcy Code, the character of a debtor’s property is determined by applicable non-bankruptcy law. Therefore, in the event Enduro Operating or the Trust becomes a debtor in a proceeding under the Bankruptcy Code, a bankruptcy court should find that the interests conveyed in the Conveyance (a) constitute real property interests under New Mexico law rather than contractual rights to receive payment, and (b) are not property of Enduro Operating’s or the Trust’s bankruptcy estate and Enduro Operating or the Trust, as a debtor in possession, or its trustee in bankruptcy, would not be able to reject the Conveyance as an executory contract.

In rendering such opinion, such counsel may (i) rely in respect of matters of fact upon certificates of officers and other employees of the Company and the Trustee and upon information obtained from public officials, (ii) assume that all documents submitted to them as originals are authentic, that all copies submitted to them conform to the originals thereof, and that the signatures on all documents examined by them are genuine, (iii) state that their opinion is limited to the laws of the State of New Mexico and (iv) 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 tax statutes to which the Company or the Trust may be subject.
