As Representatives of the several
Underwriters named in Schedule 1 attached hereto,

Ladies and Gentlemen:

Enduro Resource Partners LLC, a Delaware limited liability company (the “Company”), proposes to sell an aggregate of 13,200,000 trust units (the “Firm Units”) of beneficial interest (the “Trust Units”) of Enduro Royalty Trust, a statutory trust formed under the laws of Delaware (the “Trust”). In addition, the Company proposes to grant the underwriters (the “Underwriters”) named in Schedule 1 attached to this agreement (this “Agreement”) an option to purchase up to an additional 1,980,000 Trust Units on the terms set forth in Section 3 (the “Option Units”). The Firm Units and the Option Units, if purchased, are hereinafter collectively called the “Units.” This is to confirm the agreement concerning the purchase of the Units from the Company by the Underwriters. Barclays Capital Inc., Citigroup Global Markets Inc., Xxxxxxx, Xxxxx & Co., RBC Capital Markets, LLC and Xxxxx Fargo Securities, LLC are acting as the representatives of the several Underwriters and in such capacity are referred to in this Agreement as the “Representatives.”

The entire number of Firm Units are divided into two tranches. The first tranche consists of 6,732,000 Firm Units (the “Exchange Units”), which will be purchased from the Company by the Underwriters designated as purchasers of Exchange Units as set out in Schedule 1 (the “Exchange Underwriters”). The second tranche consists of 6,468,000 Firm Units (the “Non-Exchange Units”), which will be purchased from the Company by the Underwriters designated as purchasers of Non-Exchange Units as set out on Schedule 1 (the “Non-Exchange Underwriters”). The second tranche also includes the Directed Trust Units, as defined below. For the avoidance of doubt, the Option Units are not divided into tranches.

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 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 Texas, New Mexico and Louisiana after deduction of all royalties and other burdens on production thereon in exchange for 33,000,000 Trust Units.

It is further 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 an Agreement and Plan of Merger to be dated the Closing Date (the “Double Survivor Merger Agreement”), between Enduro Texas LLC (“Enduro Texas” or the “Grantee”), a Texas limited liability company, and Enduro Operating LLC (“Enduro Operating” or the “Grantor”), a Texas limited liability company, a merger (the “Double Survivor Merger”) will occur effective as of the Closing Date pursuant to which (i) the Net Profits Interest will be allocated to and vested in the Grantee and (ii) the other assets and liabilities of the Grantor will be retained by it. In connection with and by way of the Double Survivor Merger, the Grantor will execute and deliver on the Closing Date a conveyance of the Net Profits Interest (the “Conveyance”) in favor of the Grantee effective as of July 1, 2011.

(b) Immediately following the Double Survivor Merger, pursuant to an Agreement and Plan of Merger to be dated the Closing Date (the “Trust Merger Agreement”), between the Grantee and the Trust, the Grantee will merge with and into the Trust (the “Trust Merger” and, together with the Double Survivor Merger, the “Mergers”) effective as of the Closing Date, with the Trust surviving the Merger, pursuant to which, among other things, the Trustee, acting as trustee of the Trust will be deemed to be the “Grantee” under the Conveyance. In connection with and by way of the Merger, the Grantor, the Grantee and the Trust will enter into a supplement to the Conveyance (the “Conveyance Supplement”).

(d) The Trust Agreement of the Trust by and among the Company, The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), and Wilmington Trust Company, as Delaware trustee (the “Delaware Trustee”) (the “Organizational Trust Agreement”), will be amended and restated (as so amended and restated, the “Trust Agreement”).

(e) 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 completion of the offering of the Units (the “Registration Rights Agreement”).

The transactions contemplated above are referred to herein as the “Transactions.” The “Transaction Documents” shall mean the Double Survivor Merger Agreement, the Conveyance, the Trust Merger Agreement, the Conveyance Supplement and the Registration Rights Agreement.

The “Organizational Documents” shall mean the Organizational Trust Agreement, the Trust Agreement, the Certificate of Trust of the Trust and the Certificate of Formation and the Limited Liability Company Agreement of each of the Company, the Grantor and the Grantee, in each case as amended to date.

The “Operative Agreements” shall mean the Transaction Documents, the Organizational Trust Agreement and the Trust Agreement.

It is further understood and agreed to by all parties hereto that approximately 660,000 of the Firm Units (the “Directed Trust Units”) will initially be reserved by the several Underwriters for offer and sale upon the terms and conditions to be set forth in the most recent Preliminary Prospectus (as defined in Section 1) and in accordance with the rules and regulations of the Financial Industry Regulatory Authority, Inc. (“FINRA”) to employees of the Company and its subsidiaries and persons having business relationships with the Company and its subsidiaries who have heretofore delivered to Barclays Capital Inc. offers or indications of interest to purchase Firm Units in form satisfactory to Barclays Capital Inc. (such program, the “Directed Unit Program”) and that any allocation of such Firm Units among such persons will be made in accordance with timely directions received by Barclays Capital Inc. from the Company; provided that under no circumstances will Barclays Capital Inc. or any Underwriter be liable to the Trust or the Company or to any such person for any action taken or omitted in good faith in connection with such Directed Unit Program. It is further understood that any Directed Trust Units not affirmatively reconfirmed for purchase by any participant in the Directed Unit Program by 8:00 A.M., New York City time, on the first business day following the date hereof or otherwise not purchased by such persons will be offered by the Underwriters to the public upon the terms and conditions set forth in the Prospectus (as defined in Section 1).

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.

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 Exchange Units to the Exchange Underwriters, and each of the Exchange Underwriters, severally and not jointly, agrees to purchase the number of Exchange Units set forth opposite that Exchange Underwriter’s name in Schedule 1 hereto. The Company shall be permitted to assign the rights (but not its obligations) with respect to the sale of the Exchange Units to a “qualified intermediary” (as defined in Treasury Regulation 1.1031(k)-1(g)(4)).

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.

10. Indemnification and Contribution.

(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 (in the case of any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or any amendment or supplement thereto or in any Permitted Issuer Information, Marketing Materials or any Blue Sky Application, 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 (in the case of any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or any amendment or supplement thereto or in any Permitted Issuer Information, Marketing Materials or Blue Sky Application, 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), 10(b), or 10(g) 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.

(g) The Trust and the Company shall indemnify and hold harmless Barclays Capital Inc. (including its affiliates, directors, officers, employees and agents) and each person, if any, who controls Barclays Capital Inc. within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (“Barclays Entities”), from and against any loss, claim, damage or liability or any action in respect thereof to which any of the Barclays Entities may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action (i) arises out of, or is based upon, any untrue statement or alleged untrue statement of a material fact contained in any material prepared by or with the approval of the Trust or the Company for distribution to Directed Unit Participants in connection with the Directed Unit Program or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) arises out of, or is based upon, the failure of the Directed Unit Participant to pay for and accept delivery of Directed Trust Units that the Directed Unit Participant agreed to purchase or (iii) is otherwise related to the Directed Unit Program; provided that neither the Trust nor the Company shall be liable under this clause (iii) for any loss, claim, damage, liability or action that is determined in a final judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the Barclays Entities. The Company shall reimburse the Barclays Entities promptly upon demand for any legal or other expenses reasonably incurred by them in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred.

As Representative of the several
Underwriters named in Schedule 1,
c/o Barclays Capital Inc.
000 Xxxx Xxxxxx
Xxx Xxxx, Xxx Xxxx 00000

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 180th day after the date of the Prospectus relating to the Offering (such 180-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.

With your consent, based solely on certificates from public officials, we confirm that Enduro Operating LLC is validly existing and in good standing under the laws of the State of Texas.

3. Enduro Texas LLC is a limited liability company duly formed under the laws of the State of Texas with limited liability company power and authority to own its properties, including the Net Profits Interest, and to convey all right, title and interest in the Net Profits Interest to the Trust as contemplated in the Trust Merger Agreement. With your consent, based solely on certificates from public officials, we confirm that Enduro Texas LLC is validly existing and in good standing under the laws of the State of Texas.

4. The Company has limited liability company power and authority to enter into the Underwriting Agreement, the Registration Rights Agreement and the Amended and Restated Trust Agreement. The execution, delivery and performance of the Underwriting Agreement, the Registration Rights Agreement and the Amended and Restated Trust Agreement have been duly authorized by all necessary limited liability company action of the Company; and each of the Underwriting Agreement, the Registration Rights Agreement and the Amended and Restated Trust Agreement has been duly executed and delivered by the Company.

5. Enduro Operating LLC has limited liability company power and authority to enter into the Double Survivor Merger Agreement, the Conveyance and the Conveyance Supplement. The execution, delivery and performance of the Double Survivor Merger Agreement, the Conveyance and the Conveyance Supplement have been duly authorized by all necessary limited liability company action of Enduro Operating LLC; the Double Survivor Merger Agreement, the Conveyance and the Conveyance Supplement have been duly executed and delivered by Enduro Operating LLC; and the Double Survivor Merger Agreement, the Conveyance and the Conveyance Supplement are legally valid and binding agreements of Enduro Operating LLC, enforceable against it in accordance with their

B-1A-1

respective terms.

6. Enduro Texas LLC has limited liability company power and authority to enter into the Double Survivor Merger Agreement, the Conveyance, the Conveyance Supplement and the Trust Merger Agreement. The execution, delivery and performance of the Double Survivor Merger Agreement, the Conveyance, the Conveyance Supplement and the Trust Merger Agreement have been duly authorized by all necessary limited liability company action of Enduro Texas LLC; the Double Survivor Merger Agreement, the Conveyance, the Conveyance Supplement and the Trust Merger Agreement have been duly executed and delivered by Enduro Texas LLC; and the Double Survivor Merger Agreement, the Conveyance, the Conveyance Supplement and the Trust Merger Agreement are the legally valid and binding agreements of Enduro Texas LLC, enforceable against it in accordance with their respective terms.

7. The execution and delivery of the Underwriting Agreement and the Registration Rights Agreement, and the execution, delivery and performance of the Double Survivor Merger Agreement, the Conveyance, the Trust Merger Agreement, the Conveyance Supplement and the Amended and Restated Trust Agreement by the parties thereto, and the issuance of the Units by the Trust and the sale of the Units by the Company do not on the date hereof:

	i.		violate the Organizational Documents of the Company, Enduro Operating LLC or Enduro Texas LLC;

	ii.		result in the breach of or a default under any of the Specified Agreements set forth in Schedule 6 to this Agreement;

	iii.		violate any federal or Texas statute, rule or regulation applicable to the Company, Enduro Operating LLC, Enduro Texas LLC 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

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

8. 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

B-1A-2

accordance with Rule 424(b) and 430A under the Act.

9. The Registration Statement at __, 2011, including the information deemed to be a part thereof pursuant to Rule 430A under the Act, and the Prospectus, as of its date and as of the date hereof, each appeared on their face to be appropriately responsive in all material respects to the applicable form requirements for registration statements on Form S-1 under the Act and the rules and regulations of the Commission thereunder; 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.

10. The statements in the Registration Statement, Preliminary Prospectus and the Prospectus under the captions “Prospectus Summary,” “The Trust,” “Description of Trust Agreement,” and “Description of Trust Units,” insofar as they purport to constitute a summary of the terms of the Trust Units, and under the captions “Prospectus Summary,” “The Trust,” “The Underlying Properties — Environmental Matters and Regulation,” “Information About Enduro Resource Partners LLC (Enduro Sponsor) — Description of the Enduro Sponsor Limited Liability Company Agreement,” “Computation of Net Proceeds,” “Description of Trust Agreement,” “Description of Trust Units,” and “ERISA Considerations,” 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.

11. Neither the Trust nor the Company is, 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,” neither the Trust nor the Company will be required to be, registered as an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

12. To the best of our knowledge, neither the Trust nor the Company is a party to any agreement that would require the inclusion in the Registration Statement of Trust Units owned by any person or entity other than the Company.

13. The Double Survivor Merger became effective under the Texas Business Organizations Code (the “TBOC”) at the effective time set forth in the DS Certificate of Merger. Under Section 10.008 of the TBOC, pursuant to the Double Survivor Merger Agreement and the Conveyance, upon the effectiveness of the Double Survivor Merger, all rights, title and interest to the Net Profits Interests were allocated to and vested in Enduro Texas LLC as a survivor of the Double Survivor Merger, without reversion or impairment, any further act or deed or any transfer or assignment having occurred, but subject to any existing liens or other encumbrances thereon.

14. The Trust Merger became effective under the TBOC at the effective time set forth in the Trust Certificate of Merger. Under Section 10.008 of the TBOC, as provided in the Trust Merger Agreement and upon the effectiveness of the Trust Merger, all rights, title and

B-1A-3

interest to all of the real estate and other property and the liability and obligations of Enduro Texas LLC were allocated to and vested in the Trust, without reversion or impairment, any further act or deed or any transfer or assignment having occurred, but subject to any existing liens or other encumbrances thereon.

15. The Conveyance is 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 complies 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 will cause 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, following the filing of the Conveyance and the Conveyance Supplement in each county in the State of Texas where the Subject Interests are located, such purchasers and creditors of Enduro Operating LLC and Enduro Texas LLC will be deemed to purchase with notice of, and subject to, such Net Profits Interest.

16. 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.

Such counsel shall state that they have reviewed the Registration Statement, the most recent Preliminary Prospectus 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 most recent Preliminary Prospectus 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 most recent Preliminary Prospectus 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 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,

B-1A-4

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.

B-1A-5

EXHIBIT B-1B

FORM OF TAX OPINION OF XXXXXX & XXXXXXX LLP

Based on such facts and subject to the qualifications, assumptions and limitations set forth in the opinion and in the Registration Statement, the most recent Preliminary Prospectus and the Prospectus, our opinion that is filed as Exhibit 8.1 to the Registration Statement 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 XXXXXX, ARATA, MCCOLLAM, XXXXXXXXX & XXXXX, LLC

1. Each of Enduro Management and Enduro Operating is duly registered or qualified, and in good standing, with the Louisiana Secretary of State to do business in the State of Louisiana.

2. 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.

3. 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 are 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 is 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 is filed for registry in such conveyance records.

4. 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. x. Xxxxxxxx, 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.

5. 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

B-2-1

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.

6. No consent of any Louisiana court, governmental agency or body having jurisdiction over and with respect to the Trustee, the Company or their respective properties is required in connection with (i) the issuance of the Trust Units by the Trust and sale of the Trust Units by the Company as described in the Registration Statement, the most recent Preliminary Prospectus and the Prospectus, (ii) the execution, delivery and performance of the Underwriting Agreement and the Operative Agreements by the parties thereto or (iii) the consummation of the Transactions and any other transactions contemplated in the Underwriting Agreement and the Operative Agreements, except (A) for consents required under applicable state securities or “Blue Sky” laws, (B) for such consents that have been, or prior to the Initial Delivery Date will be, obtained or made, (C) for such consents that, if not obtained, would not reasonably be expected to materially impair the ability of the Trustee or the Company to consummate the Transactions or any other transactions provided for in the Underwriting Agreement or the Transaction Documents, (D) except as described in the Registration Statement, the most recent Preliminary Prospectus and the Prospectus and (E) except for the payment of applicable filing fees and costs in connection with any filings referenced in paragraph 3 above.

7. None of (i) the issuance of the Trust Units by the Trust and sale of the Trust Units by the Company as described in the Registration Statement, the Preliminary Prospectus and the Prospectus, (ii) the execution, delivery and performance of any Operative Agreement by the parties thereto or (iii) the consummation of the Transactions and any other transactions contemplated in the Subject Agreements violates or will violate any Louisiana law normally applicable to transactions of the type contemplated by the Underwriting Agreement and Conveyance (without consideration of any applicable state securities or “Blue Sky” laws) or, to our knowledge, violates or will violate any order, judgment, decree or injunction of any Louisiana court or governmental agency or body directed to the Trust or the Company or any of their respective properties or assets in a proceeding to which any of them or their respective properties or assets is a party or is bound, which violations would reasonably be expected to, individually or in the aggregate, materially impair the ability of the Trust or the Company to consummate the Transactions.

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.

FORM OF OPINION OF HINKLE, HENSLEY, XXXXXX & XXXXXX, L.L.P.

1. Enduro Operating LLC is duly registered or qualified to do business and is in good standing as a foreign limited liability company in the State of New Mexico.

2. 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 most recent Preliminary Prospectus 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.

3. The Conveyance, as amended by the Conveyance Supplement, constitutes a valid and binding agreement of the Grantor (once executed by the Grantor and delivered by the Grantor to Enduro Texas) and the Trust (once executed by Enduro Texas and delivered by Enduro Texas to the Trust)under the laws of the State of New Mexico, enforceable against the Grantor 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 will cause 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 the Grantor or Enduro Texas subsequently acquiring interests in the Subject Interests, and such purchasers and creditors of the Grantor and Enduro Texas will be deemed to purchase with notice of, and subject to, such Net Profits Interest.

4. 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.

5. No consent of or with any New Mexico court, governmental agency or body having jurisdiction over the Trust, the Grantor or their respective properties is required in connection with (i) the issuance of the Trust Units by the Trust and sale of the Trust Units by the Company as described in the Registration Statement, the most recent Preliminary Prospectus and the Prospectus, (ii) the execution, delivery and performance of the Agreement and the Operative Agreements by the parties thereto and (iii) the consummation of the Transactions and any other transactions contemplated by the Agreement and the Operative Agreements, except (A) for consents required under applicable state securities or “Blue Sky” laws in connection with the purchase and distribution of the Units by the Underwriters, (B) for such consents that have been, or prior to the Initial Delivery Date will be, obtained or made, (C) for such consents that, if not

B-3-1

obtained, would not reasonably be expected to materially impair the ability of the Trust or the Grantor to consummate the Transactions or any other transactions provided for in this Agreement or the Transaction Documents and (D) except as described in the Registration Statement.

6. None of (i) the issuance of the Trust Units by the Trust and sale of the Trust Units by the Company as described in the Registration Statement, Preliminary Prospectus and the Prospectus, (ii) the execution, delivery and performance of the Agreement and the Operative Agreements by the parties thereto or (iii) the consummation of the Transactions and any other transactions contemplated by the Agreement and the Operative Agreements, violates or will violate any New Mexico statute, law or regulation or any order, judgment, decree or injunction known to such counsel of any New Mexico court or governmental agency or body directed to the Trust or the Company or any of their respective properties or assets in a proceeding to which any of them or their respective properties or assets is a party or is bound.

7. Under the Bankruptcy Code, the character of a debtor’s property is determined by applicable non-bankruptcy law. Therefore, in the event the Grantor or Enduro Texas 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 the Grantor’s or Enduro Texas’s bankruptcy estate and the Grantor or Enduro Texas, as a debtor in possession, or its trustee in bankruptcy, would not be able to reject the Conveyance as an executory contract.

8. The Double Survivor Merger and the Trust Merger became effective under New Mexico law prior to the Initial Delivery Date. The Double Survivor Merger is sufficient under the laws of the State of New Mexico to vest in Enduro Texas the Net Profits Interest. The Trust Merger is sufficient under the laws of the State of New Mexico to vest in the Trust as successor to Enduro Texas all of the rights of Enduro Texas in the Net Profits Interest.

9. The Certificates of Merger for the Double Survivor Merger and the Trust Merger are in a form legally sufficient for recordation in the appropriate public offices of the State of New Mexico, to the extent such recordation is required, and, upon proper recordation of any such Certificates of Merger in the appropriate records of the applicable counties of the State of New Mexico, will constitute notice to all third parties under the recordation statutes of the State of Texas concerning record title to the Net Profits Interest vested by operation of law pursuant to the Double Survivor Merger and the Trust Merger; and the offices of the County Clerk for each county in which the Subject Interests are located are the appropriate public offices in the State of New Mexico for the recordation of such Certificates of Merger.

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.
