Genesis Energy, L.P., a Delaware limited partnership (the “Partnership”), and Genesis Energy Finance Corporation, a Delaware corporation (“Finance Corp.” and, together with the Partnership, the “Issuers”), propose to issue and sell to the several underwriters named in Schedule A hereto (the “Underwriters”), acting severally and not jointly, the respective amounts set forth in such Schedule A of $600,000,000 aggregate principal amount of the Partnership’s 8.000% Senior Notes due 2033 (the “Notes”). Wells Fargo Securities, LLC has agreed to act as the representative of the several Underwriters (the “Representative”) in connection with the offering and sale of the Notes and the Guarantees (as defined below), which are collectively referred to herein as the “Securities.”

The Securities will be issued pursuant to an indenture, dated as of May 21, 2015 (the “Base Indenture”), among the Issuers, certain subsidiaries of the Partnership named therein as guarantors and U.S. Bank, National Association, a national banking association and the original trustee under such indenture (the “Original Trustee”), as amended by the Agreement of Resignation, Appointment and Acceptance, dated September 30, 2020 (the “Trustee Replacement Agreement”) pursuant to which the Original Trustee resigned as trustee thereunder and Regions Bank, an Alabama banking corporation, became the successor trustee thereunder (the “Trustee”), and as further amended and supplemented by the Twenty-Second Supplemental Indenture, to be dated as of December 19, 2024 (the “Supplemental Indenture”), among the Issuers, the Guarantors (as defined below) and the Trustee (the Base Indenture, as so amended and supplemented, being referred to herein as the “Indenture”). The payment of principal of, and premium, if any, and interest on, the Notes will be fully and unconditionally guaranteed on a senior unsecured basis, jointly and severally, by (i) the entities listed on the signature pages hereof as “Guarantors” (collectively, the “Guarantors”) and (ii) any Subsidiary (as defined below) of the Partnership formed or acquired after the Closing Date (as defined in Section 2(b)) that executes a supplemental indenture in accordance with the terms of the Indenture, and their respective successors and assigns, pursuant to their guarantees included in the Indenture (the “Guarantees”). The Issuers and the Guarantors are herein collectively referred to as the “Obligors.”

The Notes will be issued in book-entry form in the name of Cede & Co., as nominee of The Depository Trust Company (the “Depositary”), pursuant to a letter of representations dated November 17, 2010 (the “DTC Agreement”) from the Issuers to the Depositary. This agreement (this “Agreement”), the DTC Agreement, the Indenture and the Securities are referred to herein collectively as the “Transaction Documents.”

The Obligors have prepared and filed with the United States Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (File No. 333-278743), which contains a base prospectus, dated April 16, 2024 (the “Base Prospectus”), to be used in connection with the public offering and sale of debt securities, including the Securities, and other securities of the Obligors under the Securities Act of 1933 (as amended, the “Securities Act,” which term, as used herein, includes the rules and regulations of the Commission promulgated thereunder), and the offering thereof from time to time in accordance with Rule 415 under the Securities Act. Such registration statement, including the financial statements, exhibits and schedules thereto, in the form in which it or any part thereof became effective under the Securities Act, as amended at or prior to such effective date, and including any required information deemed to be a part thereof at the time of effectiveness pursuant to Rule 430B under the Securities Act, is called the “Registration Statement.” The term “Prospectus” shall mean the final prospectus supplement relating to the Securities, together with the Base Prospectus, that is first filed pursuant to Rule 424(b) under the Securities Act after the date and time that this Agreement is executed (the “Execution Time”) by the parties hereto. The term “Preliminary Prospectus” shall mean any preliminary prospectus supplement relating to the Securities, together with the Base Prospectus, that is first filed with the Commission pursuant to Rule 424(b) under the Securities Act. Any reference herein to the Registration Statement, the Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents that are or are deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act prior to 4:15 p.m., Eastern Time, on December 5, 2024 (the “Time of Sale”).

Each of the Obligors hereby confirms its agreements with the Underwriters as follows:

SECTION 1. Representations and Warranties. Each Obligor, jointly and severally, hereby represents, warrants and covenants to each Underwriter that, as of the date hereof, as of the Time of Sale and as of the Closing Date (in each case, a “Representation Date”) as follows:

(a) Compliance with Registration Requirements.

(i) The Obligors meet the requirements for use of Form S-3 under the Securities Act. The Registration Statement became effective under the Securities Act upon filing with the Commission. No stop order suspending the effectiveness of the Registration Statement has been issued under the Securities Act and no proceedings for that purpose have been instituted or are pending or, to any Obligor’s knowledge, are contemplated or threatened by the Commission. In addition, the Indenture has been duly qualified under the Trust Indenture Act of 1939 (as amended, the “Trust Indenture Act,” which term, as used herein, includes the rules and regulations of the Commission promulgated thereunder).

(ii) At each Representation Date, the Registration Statement and any amendments thereto (A) complied and will comply in all material respects with the requirements of the Securities Act and the Trust Indenture Act, and (B) did not and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. At each Representation Date, neither the Prospectus, nor any amendments or supplements thereto included or will include an untrue statement of a material fact or omitted or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. Notwithstanding the foregoing, the representations and warranties in this Section 1(a)(ii) shall not apply to (x) that part of the Registration Statement that constitutes the Trustee’s Statement of Eligibility on Form T-1 under the Trust Indenture Act and (y) statements in or omissions from the Registration Statement or any post-effective amendment thereto or the Prospectus or any amendments or supplements thereto made in reliance upon and in conformity with the information furnished to the Partnership in writing by the Representative on behalf of any Underwriter expressly for use therein, it being understood and agreed that the only such information furnished by the Representative on behalf of any Underwriter consists of the information described as such in the penultimate sentence of Section 8(b).

3

(iii) Each Preliminary Prospectus and the Prospectus, at the time each was filed with the Commission, complied in all material respects with the Securities Act, and the Preliminary Prospectus and the Prospectus delivered to the Underwriters for use in connection with the offering of the Securities will, at the time of such delivery, be identical to any electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

(b) The Pricing Disclosure Package. The term “Pricing Disclosure Package” shall mean (i) the Preliminary Prospectus dated December 5, 2024, (ii) the issuer free writing prospectuses as defined in Rule 433 of the Securities Act (each, an “Issuer Free Writing Prospectus”), if any, identified in Annex I hereto, and (iii) any other free writing prospectus that the parties hereto shall hereafter expressly agree in writing to treat as part of the Pricing Disclosure Package. As of the Time of Sale, the Pricing Disclosure Package did not contain or represent an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from the Pricing Disclosure Package made in reliance upon and in conformity with the information furnished to the Partnership in writing by the Representative on behalf of any Underwriter expressly for use in the Pricing Disclosure Package, it being understood and agreed that the only such information furnished by the Representative on behalf of any Underwriter consists of the information described as such in the penultimate sentence of Section 8(b).

(c) Incorporated Documents and Partnership SEC Documents. The documents incorporated or deemed to be incorporated by reference in the Registration Statement, the Pricing Disclosure Package and the Prospectus (i) at the time they were or hereafter are filed with the Commission, complied and will comply in all material respects with the requirements of the Exchange Act and (ii) when read together with the other information in the Pricing Disclosure Package, at the Time of Sale, and when read together with the other information in the Prospectus, at the date of the Prospectus and at the Closing Date, did not or will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The Partnership has timely filed with the Commission all forms, registration statements, reports, schedules and statements required to be filed by it under the Exchange Act or the Securities Act (all such documents filed on or prior to the date of this Agreement, but specifically excluding any documents “furnished,” collectively, the “Partnership SEC Documents”).

(d) Partnership is a Well-Known Seasoned Issuer. (i) At the time of filing the Registration Statement, (ii) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the Securities Act (regardless of whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or Section 15(d) of the Exchange Act or form of prospectus), (iii) at the time any of the Obligors or any person acting on an Obligor’s behalf (within the meaning, for this clause (iii) only, of Rule 163(c) of the Securities Act) made any offer relating to the Securities in reliance on the

4

exemption of Rule 163 of the Securities Act, and (iv) as of the Execution Time, each of the Issuers was and is a “well known seasoned issuer” as defined in Rule 405 of the Securities Act. The Registration Statement is an “automatic shelf registration statement,” as defined in Rule 405 of the Securities Act, that automatically became effective not more than three years prior to the Execution Time; the Issuers have not received from the Commission any notice pursuant to Rule 401(g)(2) of the Securities Act objecting to use of the automatic shelf registration statement form and the Issuers have not otherwise ceased to be eligible to use the automatic shelf registration statement form.

(f) Issuer Free Writing Prospectuses. Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the offering of Securities under this Agreement or until any earlier date that the Partnership notified or notifies the Representative as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement, the Pricing Disclosure Package or the Prospectus. If at any time following issuance of an Issuer Free Writing Prospectus there occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicts or would conflict with the information contained in the Registration Statement, the Pricing Disclosure Package or the Prospectus, the Partnership will promptly notify the Representative and amend or supplement, at its own expense and subject to the approval of the Representative, such Issuer Free Writing Prospectus to eliminate or correct such conflict. The foregoing two sentences do not apply to statements in or omissions from any Issuer Free Writing Prospectus made in reliance upon and in conformity with information furnished to the Partnership in writing by the Representative on behalf of any Underwriter expressly for use therein, it being understood and agreed that the only such information furnished by the Representative on behalf of any Underwriter consists of the information described as such in the penultimate sentence of Section 8(b).

(g) Issuer Additional Written Communications. None of the Obligors have distributed or will distribute, prior to the later of the Closing Date and the completion of the Underwriters’ distribution of the Securities, any offering material in connection with the offering and sale of the Securities, other than (i) the Registration Statement, the Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus reviewed and consented to by the Representative and included in Annex I hereto or (ii) any electronic road show or other written communications reviewed and consented to by the Representative and listed on Annex II hereto (such information described in this Section 1(g)(ii) shall be referred to as an “Issuer Additional Written Communication”). Each such Issuer Additional Written Communication, when taken

5

together with the Pricing Disclosure Package, did not as of the Time of Sale, and at the Closing Date will not, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from any Issuer Additional Written Communication made in reliance upon and in conformity with information furnished to the Partnership in writing by the Representative on behalf of any Underwriter expressly for use therein, it being understood and agreed that the only such information furnished by the Representative on behalf of any Underwriter consists of the information described as such in the penultimate sentence of Section 8(b).

The Obligors shall effect the filings required pursuant to Rule 424(b) under the Securities Act, in the manner and within the time period required by Rule 424(b), and shall take such steps as the Partnership deems necessary to ascertain promptly whether the Preliminary Prospectus and the Prospectus transmitted for filing under Rule 424 were received for filing by the Commission and, in the event that any of them was not, the Issuers shall promptly file such document. The Obligors shall use their reasonable best efforts to prevent the issuance of any stop order referred to above and, if any such stop order is issued, to obtain the lifting thereof at the earliest possible moment.

22

(ii) Filing of Amendments. During the period beginning on the Execution Date and ending on the later of the Closing Date or such date as, in the opinion of counsel for the Underwriters, the Prospectus is no longer required by law to be delivered in connection with sales of the Securities by an Underwriter or dealer, including in circumstances where such requirement may be satisfied pursuant to Rule 172 under the Securities Act (the “Prospectus Delivery Period”), the Issuers shall give the Representative notice of its intention to file or prepare any amendment to the Registration Statement, or any amendment, supplement or revision to the Pricing Disclosure Package or the Prospectus, whether pursuant to the Securities Act, the Exchange Act or otherwise, other than a Current Report on Form 8-K disclosing the terms of this Agreement and containing exhibits to the Registration Statement, shall furnish the Representative with copies of any such documents a reasonable amount of time prior to such proposed filing or use, as the case may be, and shall not file or use any such document to which the Representative or counsel for the Underwriters shall reasonably object in writing (unless the Partnership is advised by counsel that it is required by law to make such filing).

(iii) Delivery of Registration Statements. The Issuers have furnished or will deliver to the Representative upon request a reasonable number of copies of the Registration Statement, as initially filed with the Commission, and of all amendments thereto (including all exhibits thereto and documents incorporated by reference therein) and sufficient copies of the foregoing (other than exhibits) for distribution of a copy to each of the other Underwriters. The Registration Statement and each amendment thereto furnished to the Underwriters will be identical to any electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

(iv) Delivery of Prospectuses. The Issuers shall deliver to each Underwriter, without charge, as many copies of the Preliminary Prospectus as such Underwriter may reasonably request (exclusive of Incorporated Documents), and the Issuers hereby consent to the use of such copies for purposes permitted by the Securities Act. The Issuers shall furnish to each Underwriter, without charge, during the Prospectus Delivery Period, such number of copies of the Prospectus (exclusive of Incorporated Documents) as such Underwriter may reasonably request. The Preliminary Prospectus and the Prospectus and any amendments or supplements thereto furnished to the Underwriters shall be identical to any electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

23

(v) Continued Compliance with Securities Laws. The Obligors shall comply with the Securities Act and the Exchange Act so as to permit the completion of the distribution of the Securities as contemplated in this Agreement and in the Registration Statement, the Pricing Disclosure Package and the Prospectus. If at any time during the Prospectus Delivery Period, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriters or for the Partnership, to amend the Registration Statement in order that the Registration Statement will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading or to amend or supplement the Pricing Disclosure Package or the Prospectus in order that the Pricing Disclosure Package or the Prospectus, as the case may be, will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at the Time of Sale or at the time it is delivered or conveyed to a purchaser, not misleading, or if it shall be necessary, in the opinion of either such counsel, at any such time to amend the Registration Statement or amend or supplement the Pricing Disclosure Package or the Prospectus in order to comply with the requirements of any law, the Issuers shall (i) notify the Representative of any such event, development or condition and (ii) promptly prepare and file with the Commission, subject to Section 3(a)(ii), such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement, the Pricing Disclosure Package or the Prospectus comply with such law, and the Issuers shall furnish to the Underwriters, without charge, such number of copies of such amendment or supplement as the Underwriters may reasonably request.

(vi) Blue Sky Compliance. Each of the Obligors shall cooperate with the Representative and counsel for the Underwriters to qualify or register (or to obtain exemptions from qualifying or registering) all or any part of the Securities for offer and sale under the securities laws of the several states of the United States or any other jurisdictions reasonably designated by the Representative, shall comply with such laws and shall continue such qualifications, registrations and exemptions in effect so long as required for the distribution of the Securities. None of the Obligors shall be required to qualify as a foreign entity or to take any action that would subject it to general service of process in any such jurisdiction where it is not presently qualified or where it would be subject to taxation as a foreign entity. The Obligors shall advise the Representative promptly of the suspension of the qualification or registration of (or any such exemption relating to) the Securities for offering, sale or trading in any jurisdiction or any initiation or threat of any proceeding for any such purpose, and in the event of the issuance of any order suspending such qualification, registration or exemption, each of the Obligors shall use their respective reasonable best efforts to obtain the withdrawal thereof at the earliest possible moment.

(vii) Use of Proceeds. The Issuers shall apply the net proceeds from the sale of the Securities in the manner described under the caption “Use of Proceeds” in the Pricing Disclosure Package and the Prospectus.

(viii) The Depositary. The Issuers shall cooperate with the Underwriters and use their reasonable best efforts to permit the Securities to be eligible for clearance and settlement through the facilities of the Depositary.

(xi) Final Term Sheet. The Issuers shall prepare a final term sheet in a form approved by the Representative and attached as Annex III hereto, and shall file such term sheet pursuant to Rule 433(d) under the Securities Act within the time required by such rule (such term sheet, the “Final Term Sheet”). Any such Final Term Sheet is an Issuer Free Writing Prospectus for purposes of this Agreement.

(xii) Permitted Free Writing Prospectuses. Each of the Obligors represents that it has not made, and agrees that, unless it obtains the prior written consent of the Representative, it shall not make, any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 under the Securities Act) required to be filed by such Obligor with the Commission or retained by such Obligor under Rule 433 under the Securities Act; provided that the prior written consent of the Representative shall be deemed to have been given in respect of any Issuer Free Writing Prospectuses included in Annex I to this Agreement. Any such free writing prospectus consented to or deemed to be consented to by the Representative is hereinafter referred to as a “Permitted Free Writing Prospectus.” Each of the Obligors agrees that (i) it has treated and shall treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus, and (ii) has complied and shall comply, as the case may be, with the requirements of Rules 164 and 433 under the Securities Act applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

25

(xiii) Notice of Inability to Use Automatic Shelf Registration Statement Form. If at any time during the Prospectus Delivery Period, the Issuers receive from the Commission a notice pursuant to Rule 401(g)(2) under the Securities Act or otherwise cease to be eligible to use the automatic shelf registration statement form, the Issuers shall (i) promptly notify the Representative, (ii) promptly file a new registration statement or post-effective amendment on the proper form relating to the Securities, in a form reasonably satisfactory to the Representative, (iii) use their respective best efforts to cause such registration statement or post-effective amendment to be declared effective and (iv) promptly notify the Representative of such effectiveness. The Issuers shall take all other action reasonably necessary or appropriate to permit the public offering and sale of the Securities to continue as contemplated in the registration statement that was the subject of the Rule 401(g)(2) notice or for which the Issuers have otherwise become ineligible. References herein to Registration Statement shall include such new registration statement or post-effective amendment, as the case may be.

(xiv) Filing Fees. The Issuers agree to pay the required Commission filing fees relating to the Securities within the time required by and in accordance with Rules 456(b)(1) and 457(r) under the Securities Act.

(xv) Compliance with Sarbanes-Oxley Act.

(xvi) Earnings Statement. As soon as practicable, the Partnership will make generally available to its security holders and the Underwriters an earnings statement (which need not be audited) satisfying the requirements of Section 11(a) of the Securities Act and Rule 158 of the rules and regulations of the Commission thereto.

(xvii) No Manipulation of Price. None of the Obligors shall take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, under the Exchange Act or otherwise, the stabilization or manipulation of the price of any securities of any Obligor to facilitate the sale or resale of the Securities.

The Representative, on behalf of the several Underwriters, may, in its sole discretion, waive in writing the performance by any Obligor of any one or more of the foregoing covenants or extend the time for their performance.

SECTION 4. Payment of Expenses. Each of the Obligors agrees jointly and severally to pay all costs, fees and expenses incurred in connection with the performance of its obligations hereunder and in connection with the transactions contemplated hereby, including, without limitation, (i) all expenses incident to the issuance and delivery of the Securities (including all printing and engraving costs), (ii) all necessary issue, transfer and other stamp taxes in connection with the original issuance and sale of the Securities to the Underwriters, (iii) all fees

26

SECTION 5. Conditions of the Obligations of the Underwriters. The obligations of the several Underwriters to purchase and pay for the Securities as provided herein on the Closing Date shall be subject to the accuracy of the representations and warranties on the part of the Obligors set forth in Section 1 hereof as of the date hereof and as of the Closing Date as though then made and to the timely performance by the Obligors of their respective covenants and other obligations hereunder, and to each of the following additional conditions:

(ii) there shall not have occurred any downgrading, nor shall any notice have been given of any intended or potential downgrading or of any review for a possible change that does not indicate the direction of the possible change, in the rating accorded any of the Obligors or any of their respective securities by any “nationally recognized statistical rating organization” as such term is defined in Section 3(a)(62) under the Exchange Act.

Each of the Obligors, jointly and severally, agrees to indemnify and hold harmless each Underwriter, its affiliates, directors, officers and employees, and each person, if any, who controls any Underwriter within the meaning of the Securities Act and the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which such Underwriter, affiliate, director, officer, employee or controlling person may become subject under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Partnership), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Issuer Additional Written Communication or the Prospectus (or any amendment or supplement to any of the foregoing), or (ii) the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein (in the case of the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Issuer Additional Written Communication or the Prospectus, in the light of the circumstances under which they were made) not misleading; and to reimburse each Underwriter and each such affiliate, director, officer, employee or controlling person for any and all expenses (including the reasonable fees and disbursements of counsel chosen by the Representative) as such expenses are reasonably incurred by such Underwriter or such affiliate, director, officer, employee or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Partnership by such Underwriter through the Representative expressly for use in the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Issuer Additional Written Communication or the Prospectus (or any amendment or supplement to any of the foregoing), it being understood and agreed that the only such information furnished by the Representative on behalf of any Underwriter consists of the information described as such in the penultimate sentence of Section 8(b). The indemnity agreement set forth in this Section 8(a) shall be in addition to any liabilities that the Obligors may otherwise have.

30

(b) Indemnification of the Obligors. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless each of the Obligors, each of their respective directors and each person, if any, who controls an Obligor within the meaning of the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which an Obligor or any such director or controlling person may become subject, under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Underwriter), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Issuer Additional Written Communication or the Prospectus (or any amendment or supplement to any of the foregoing), or (ii) the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein (in the case of the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Issuer Additional Written Communication or the Prospectus, in the light of the circumstances under which they were made) not misleading; and to reimburse each Obligor and each such director or controlling person for any and all expenses (including the fees and disbursements of counsel) as such expenses are reasonably incurred by each Obligor or such director or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Issuer Additional Written Communication or the Prospectus (or any amendment or supplement to any of the foregoing), in reliance upon and in conformity with written information furnished to the Partnership by such Underwriter through the Representative expressly for use in the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Issuer Additional Written Communication or the Prospectus (or any amendment or supplement to any of the foregoing). Each of the Obligors hereby acknowledge that the only information that the Underwriters through the Representative have furnished to the Partnership expressly for use in the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Issuer Additional Written Communication or the Prospectus (or any amendment or supplement to any of the foregoing) are the statements set forth in the table in the first paragraph, the first and third sentences of the third paragraph and the third sentence of the ninth paragraph under the caption “Underwriting” in Preliminary Prospectus and the Prospectus. The indemnity agreement set forth in this Section 8(b) shall be in addition to any liabilities that each Underwriter may otherwise have.

(c) Notifications and Other Indemnification Procedures. Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; provided that the failure to so notify the indemnifying party will not relieve it from any liability that it may have to any indemnified party under this Section 8 except to the extent that it has been materially prejudiced by such failure (through the forfeiture of substantive rights and defenses) and shall not relieve the indemnifying party from any liability that the indemnifying

31

party may have to an indemnified party other than under this Section 8. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof (other than the reasonable costs of investigation) unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with local counsel (in each jurisdiction)), which shall be selected by the Representative (in the case of counsel representing the Underwriters or their related persons), representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party.

(d) Settlements. The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, which will not be unreasonably withheld, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by this Section 8, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request or disputed in good faith the indemnified party’s entitlement to such reimbursement prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (ii) does not include any statements as to or any findings of fault, culpability or failure to act by or on behalf of any indemnified party.

32

SECTION 9. Contribution. If the indemnification provided for in Section 8 hereof is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Obligors, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) 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 Obligors, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions or inaccuracies in the representations and warranties herein that resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Obligors, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Issuers and the total discount received by the Underwriters bear to the aggregate initial offering price of the Securities. The relative fault of the Obligors, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact or any such inaccurate or alleged inaccurate representation or warranty relates to information supplied by the Obligors, on the one hand, or the Underwriters, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or inaccuracy.

The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 8 hereof, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in Section 8 hereof with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 9; provided, however, that no additional notice shall be required with respect to any action for which notice has been given under Section 8 hereof for purposes of indemnification.

The Obligors and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in this Section 9.

Notwithstanding the provisions of this Section 9, no Underwriter shall be required to contribute any amount in excess of the discount received by such Underwriter in connection with the Securities distributed by it. No person guilty of fraudulent misrepresentation (within the meaning of Section 11 of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 9 are several, and not joint, in proportion to their respective commitments as set forth opposite their names in Schedule A. For purposes of this Section 9, each affiliate, director, officer and employee of an Underwriter and each person, if any, who controls an Underwriter within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as such Underwriter, and each director of any Obligor, and each person, if any, who controls any Obligor within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Obligors, as applicable.

SECTION 10. Termination of this Agreement. Prior to the Closing Date, this Agreement may be terminated by the Representative by notice given to the Partnership if at any time: (i) trading or quotation in any of the Partnership’s securities shall have been suspended or materially limited by the Commission or by the NYSE, or trading in securities generally on either the Nasdaq Stock Market or the NYSE shall have been suspended or materially limited, or minimum or maximum prices shall have been generally established on any of such quotation system or stock exchange by the Commission or FINRA; (ii) a general banking moratorium shall have been declared by federal, New York or Delaware authorities; or (iii) there shall have occurred any outbreak or escalation of national or international hostilities involving the United States or any crisis or calamity, or any change in the United States or international financial markets, or any substantial change or development in United States’ or international political, financial or economic conditions, if the effect of any such event specified in clauses (i) through (iii) is, in the sole judgment of the Representative, so material or adverse as to make it impractical or inadvisable to proceed with the public offering, sale or the delivery of the Securities on the terms and in the manner contemplated in this Agreement and in the Pricing Disclosure Package and the Prospectus. Any termination pursuant to this Section 10 shall be without liability on the part of (i) any Obligor to any Underwriter, except that the Obligors shall be obligated to reimburse the expenses of the Underwriters pursuant to Sections 4 and 6 hereof, (ii) any Underwriter to any Obligor, or (iii) any party hereto to any other party except that the provisions of Sections 4, 6, 8, 9 and 16 hereof shall at all times be effective and shall survive such termination.

SECTION 11. Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of the Obligors, their respective officers and the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, any Obligor or any of their partners, officers or directors or any controlling person, as the case may be, and will survive delivery of and payment for the Securities sold hereunder and any termination of this Agreement.

(a) THE VALIDITY AND INTERPRETATION OF THIS AGREEMENT AND THE TERMS AND CONDITIONS SET FORTH HEREIN SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

(b) Consent to Jurisdiction. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (“Related Proceedings”) may be instituted in the federal courts of the United States of America located in the City and County of New York or the courts of the State of New York in each case located in the City and County of New York (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for suits, actions, or proceedings instituted in regard to the enforcement of a judgment of any Specified Court in a Related Proceeding, as to which such jurisdiction is non-exclusive) of the Specified Courts in any Related Proceeding. Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any Related Proceeding brought in any Specified Court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any Related Proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any Specified Court that any Related Proceeding brought in any Specified Court has been brought in an inconvenient forum. Each party not located in the United States irrevocably appoints CT Corporation System as its agent to receive service of process or other legal summons for purposes of any Related Proceeding that may be instituted in any Specified Court.

SECTION 17. Default of One or More of the Several Underwriters. If any one or more of the several Underwriters shall fail or refuse to purchase Securities that it or they have agreed to purchase hereunder on the Closing Date, and the aggregate number of Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase does not exceed 10% of the aggregate number of the Securities to be purchased on such date, the other Underwriters shall be obligated, severally, in the proportions that the number of Securities set forth opposite their respective names on Schedule A bears to the aggregate number of Securities set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as may be specified by the Underwriters with the consent of the non-defaulting Underwriters, to purchase the Securities which such defaulting Underwriter or Underwriters agreed but failed or

36

refused to purchase on the Closing Date. If any one or more of the Underwriters shall fail or refuse to purchase Securities and the aggregate number of Securities with respect to which such default occurs exceeds 10% of the aggregate number of Securities to be purchased on the Closing Date, and arrangements satisfactory to the Underwriters and the Partnership for the purchase of such Securities are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party except that the provisions of Sections 4, 6, 8, 9 and 16 hereof shall at all times be effective and shall survive such termination. In any such case either the Underwriters or the Issuers shall have the right to postpone the Closing Date, as the case may be, but in no event for longer than seven days in order that the required changes, if any, to the Prospectus or any other documents or arrangements may be effected.

As used in this Agreement, the term “Underwriter” shall be deemed to include any person substituted for a defaulting Underwriter under this Section 17. Any action taken under this Section 17 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

SECTION 18. No Advisory or Fiduciary Responsibility. Each of the Obligors acknowledges and agrees that: (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the public offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Obligors, on the one hand, and the several Underwriters, on the other hand, and each of the Obligors is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby and the process leading to such transaction each Underwriter is and has been acting solely as a principal and is not the financial advisor, agent or fiduciary of any Obligor or its affiliates, equityholders, creditors or employees or any other party; (iii) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of any Obligor with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the any Obligor on other matters) and no Underwriter has any other obligation to any Obligor with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement; (iv) the several Underwriters and their respective Affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Obligors, and the several Underwriters have no obligation to disclose any of such interests by virtue of any fiduciary, agency or advisory relationship; and (v) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby, and the Obligors have consulted their own legal, accounting, regulatory and tax advisors to the extent they deemed appropriate.

This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Obligors and the several Underwriters, or any of them, with respect to the subject matter hereof. The Obligors hereby waive and release, to the fullest extent permitted by law, any claims that they may have against the several Underwriters with respect to any breach or alleged breach of fiduciary duty.

37

SECTION 19. Research Analyst Independence. Each of the Obligors 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 Partnership, its Subsidiaries and/or the offering of the Securities that differ from the views of their respective investment banking divisions. Each Obligor hereby waives and releases, to the fullest extent permitted by applicable law, any claims that such Obligor 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 any Obligor by such Underwriters’ investment banking divisions. Each of the Obligors 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.

SECTION 20. Waiver of Jury Trial. The Obligors and each of the Underwriters hereby irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

SECTION 21. Recognition of the U.S. Special Resolution Regimes.

(a) In the event that any Underwriter that is a Covered Entity (as defined below) becomes subject to a proceeding under a U.S. Special Resolution Regime (as defined below), the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate (as defined below) of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights (as defined below) under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

(c) For purposes of this Section 21: (i) a “BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k); (ii) a “Covered Entity” means any of the following: (A) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (B) “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b); or (C) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b); (iii) “Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance

38

with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable; and (iv) “U.S. Special Resolution Regime” means each of (A) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (B) Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

SECTION 22. Compliance with USA PATRIOT Act. In accordance with the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law on October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Obligors, which information may include the name and addresses of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

SECTION 23. General Provisions. This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof. This Agreement may be executed in two or more counterparts, each one of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. The words “execution,” “signed,” “signature,” “delivery,” and words of like import in or relating to this Agreement and any certificate, agreement or other document to be signed in connection with this Agreement and the transactions contemplated hereby shall be deemed to include Electronic Signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including, without limitation, the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act. For the purpose of this Section 22, “Electronic Signature” means any electronic symbol or process (including, without limitation, DocuSign and AdobeSign) attached to, or associated with, a contract or other record and adopted by a person with the intent to sign, authenticate or accept such contract or record. This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit.

EXHIBIT A-1

Opinion of counsel for the Issuers to be delivered pursuant to Section 5 of the Underwriting Agreement.

(b) The Partnership is validly existing as a limited partnership and is in good standing under the laws of the State of Delaware. Finance Corp is validly existing as a corporation and is in good standing under the laws of the State of Delaware.

(c) Each of Manta Ray Gathering Company, L.L.C. (“Manta Ray”), Matagorda Offshore, LLC and Seahawk Shoreline System, LLC (collectively, the “Texas LLCs”) is validly existing as a limited liability company with the right to transact business in the State of Texas under the laws of the State of Texas.

(d) Each Guarantor, other than any of the Non-Covered Entities and the Texas LLCs, and, to the extent not constituting a Guarantor, each Material Subsidiary is validly existing as a corporation, limited liability company or limited partnership, as applicable, in good standing under the laws of the State of Delaware.

(e) Each of the Partnership Entities is duly qualified (or, in the case of the State of Texas has the right to transact business) as a foreign corporation, limited liability company or limited partnership, as applicable, in the jurisdictions so identified on Exhibit B attached hereto. Each of the Partnership Entities has all requisite entity power to own its respective properties and conduct its business, in each case in all material respects, as described in the Preliminary Prospectus Supplement and the Final Prospectus Supplement. The Partnership has the partnership power and authority necessary to execute and deliver, incur and perform any obligations it may have under any of the Transaction Documents to which it is a party and the Partnership Agreement. Finance Corp. has the corporate power and authority necessary to execute and deliver, incur and perform any obligations it may have under any of the Transaction Documents to which it is a party. Each of the Guarantors (other than the Non-Covered Entities) has the corporate or other entity power and authority necessary to execute and deliver, incur and perform any obligations it may have under any of the Transaction Documents to which it is a party. The General Partner has the limited liability company power and authority necessary to act as the general partner of the Partnership.

(b) Each of the Transaction Documents has been duly authorized, executed and delivered by each of the Covered Entities that is a party to such Transaction Document.

For purposes of this letter, we have assumed the information in the Final Prospectus Supplement of the type referred to in Rule 430B(f)(1) of the General Rules and Regulations under the Act was deemed to be a part of and included in the Registration Statement pursuant to such Rule 430B(f)(1) as of the date of the Underwriting Agreement; such date (the “Specified Effective Date”), in accordance with said Rule 430B(f), constitutes a new effective date with respect to such portions of the Registration Statement as provided for therein. Our identification of documents and information as part of the Disclosure Package has been at your request and with your approval. Such identification is for the limited purpose of making the statements set forth in this letter and is not the expression of a view by us as to whether any such information has been or should have been conveyed to investors generally or to any particular investors at any particular time or in any particular manner.

Because the primary purpose of our professional engagement was not to establish or confirm factual matters or financial and accounting information, and because many determinations involved in the preparation of the Registration Statement, the Preliminary Prospectus Supplement and the Final Prospectus Supplement are of a wholly or partially non-legal character, except as expressly set forth in paragraph (10) of this letter, we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained or incorporated by reference in the Registration Statement, the Disclosure Package and the Final Prospectus Supplement, and we make no representation that we have independently verified the accuracy, completeness or fairness of such statements.

However, in the course of our acting as counsel to the Partnership in connection with the preparation of the Registration Statement, the Final Prospectus Supplement and the Disclosure Package, we have reviewed each such document and have participated in conferences and telephone conversations with representatives of the Partnership, representatives of the independent public accountants for the Partnership, representatives of the Underwriters and representatives of the Underwriters’ counsel, during which conferences and conversations the contents of such documents and related matters were discussed.

Based on our participation in such conferences and conversations, our review of the documents described above, our understanding of the U.S. federal securities laws and the experience we have gained in our practice thereunder, we advise you that:

(a) Each of the Registration Statement (as of the date of the Underwriting Agreement), the Preliminary Prospectus Supplement (as of its date) and the Final Prospectus Supplement (as of its date) appeared on its face to be appropriately responsive in all material respects with the requirements of the Act except that we express no view as to the antifraud provisions of the Act or the financial statements, the notes and schedules thereto and other financial and accounting information included or incorporated by reference in the Registration Statement, the Preliminary Prospectus Supplement or the Final Prospectus Supplement and the Statement of Eligibility and Qualification of the Trustee on Form T-1. The Incorporated Documents, at the time that they were filed (other than the financial statements, the notes and schedules thereto and other financial and accounting information included in the Incorporated Documents, as to which we express no opinion), appear on their face to comply as to form in all material respects with the requirements of the Exchange Act except that we express no view as to the antifraud provisions of the Exchange Act. We have no knowledge of any documents that are required to be filed under the Act (but are not filed) as exhibits to the Registration Statement, or of any documents that are required under the Act to be (but are not) summarized in the Preliminary Prospectus Supplement or the Final Prospectus Supplement, except, in each case, we express no view as to (i) the antifraud provisions of the Act and (ii) the financial statements, the notes and schedules thereto and other financial and accounting information so required to be filed or summarized and the Statement of Eligibility and Qualification of the Trustee on Form T-1.

(b) No information has come to our attention that causes us to believe that (i) the Registration Statement as of the Specified 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; (ii) the Disclosure Package, as of 4:15 p.m. (New York time) on December 5, 2024 (which you have informed us is a time prior to the time of the first sale of the Notes by any Underwriter), contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they are made, not misleading or (iii) the Final Prospectus Supplement, as of its date and as of the Closing Date, contained or contains any untrue statement of a material

fact or omitted or omits to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except that in the case of each of clauses (i)-(iii) above, we do not express any view as to the financial statements, the notes and schedules thereto and other financial and accounting information contained or incorporated by reference therein and the Statement of Eligibility and Qualification of the Trustee on Form T-1.

EXHIBIT A-2

(iii) The execution of the Underwriting Agreement by the Partnership, and the consummation of the transactions by the Partnership contemplated by the Underwriting Agreement does not constitute a breach of, or default under, the articles of organization of TDC, L.L.C. or the Operating Agreement of TDC, L.L.C. as a subsidiary of the Partnership.

(iv) The membership interests of TDC, L.L.C. are validly authorized, issued, fully paid, non-assessable equity interests (except as such non-assessability may be affected by the provisions on additional capital contributions contained in the Operating Agreement of TDC, L.L.C. or in connection with the obligation of a member of a Louisiana limited liability company to return any wrongful distributions under La. R.S. 12:1328).

(v) The execution of the Underwriting Agreement by the Partnership, and the consummation of the transactions by the Partnership contemplated by the Underwriting Agreement do not create any security interest in, or lien, claim, charge or encumbrance upon, any property or assets, pursuant to the articles of organization of TDC, L.L.C. or the laws of the State of Louisiana.

(vi) The execution of the Underwriting Agreement by the Partnership and the consummation of the transactions by the Partnership contemplated by the Underwriting Agreement, as applicable to TDC, L.L.C., do not constitute a breach of, or default under, any State of Louisiana statute, rule, or regulation of general applicability which, in our experience, is normally applicable to transactions of the type contemplated by the Underwriting Agreement; provided, we express no opinion as to (a) laws of any counties, cities, towns, municipalities and special political subdivisions, and any agencies thereof, (b) laws relating to land use, zoning and building code issues, taxes, environmental issues, intellectual property laws, antitrust issues, the Employee Retirement Income Security Act of 1974, as amended, and Federal Reserve Board margin regulation issues, (c) laws, rules and regulations relating to the regulation of the conduct of the businesses of TDC, L.L.C., including, without limitation, refining services, gathering, transporting (by barge, pipeline, ship, truck or other modes of transportation), terminalling, storing, producing, acquiring, developing, exploring for, processing, dehydrating, marketing, trading, fractionating, mining and otherwise handling hydrocarbons (including crude oil, natural gas, condensate, natural gas liquids, liquefied natural gas and refined petroleum products), sulfur,

(vii) The execution and delivery of each of the Underwriting Agreement and the Indenture by TDC, L.L.C. and the performance by TDC, L.L.C. of its obligations under the Underwriting Agreement and the Indenture (including its Guarantee pursuant thereto) have been duly authorized by all necessary limited liability company action.
