In addition, solely for the purpose of covering over-allotments, the Partnership grants to the Underwriters the option to purchase from the Partnership up to an additional 750,000 Common Units (the “Additional Units”).

The registration statement, as so amended, became effective under the Act upon filing.

The Representatives may from time to time increase or decrease the public offering price after the initial public offering to such extent as they may determine.

In addition, the Partnership hereby grants to the several Underwriters the option (the “Over-Allotment Option”) to purchase, and upon the basis of the representations and warranties and subject to the terms and conditions herein set forth, the Underwriters shall have the right to purchase, severally and not jointly, from the Partnership, ratably in accordance with the number of Firm Units to be purchased by each of them, all or a portion of the Additional Units as may be necessary to cover over-allotments made in connection with the offering of the Firm Units, at the same purchase price per Common Unit to be paid by the Underwriters to the Partnership for the Firm Units. The Over-Allotment Option may be exercised by the Representatives on behalf of the several Underwriters at any time and from time to time on or before the thirtieth day following the date of the Prospectus Supplement, by written notice to the Partnership.

2. Payment and Delivery. Payment of the purchase price for the Firm Units shall be made to the Partnership to the account specified by the Partnership by Federal Funds wire transfer against delivery of the Firm Units to ▇▇▇▇▇ Fargo through the facilities of The Depository Trust Company (“DTC”) for the respective accounts of the Underwriters.

(c) The Representatives shall have received at the time of purchase and, if applicable, at the additional time of purchase, the opinion of ▇▇▇▇▇▇▇ ▇▇▇▇▇ LLP, counsel for the Underwriters, dated the time of purchase or the additional time of purchase, as the case may be, in form and substance reasonably satisfactory to the Representatives.

(d) No Prospectus or amendment or supplement to the Registration Statement or the Prospectus shall have been filed to which the Representatives shall have a right to object under this Agreement and shall have so objected in writing.

(e) The Registration Statement and any registration statement required to be filed, prior to the sale of the Units, under the Act pursuant to Rule 462(b) shall have been filed and shall have become effective under the Act. The Prospectus Supplement shall have been filed with the Commission pursuant to Rule 424(b) under the Act at or before 4:30 p.m., Houston time, on the second full business day after the date of this Agreement (or such earlier time as may be required under the Act).

(k) The Primary Stock Exchange shall not have raised any objection with respect to the fairness or reasonableness of the underwriting, or other arrangements of the transactions, contemplated hereby.

7. Effective Date of Agreement; Termination. This Agreement shall become effective when the parties hereto have executed and delivered this Agreement.

The obligations of the several Underwriters hereunder shall be subject to termination in the absolute discretion of the Representatives, if (i) since the time of execution of this Agreement or the earlier respective dates as of which information is given in the Registration Statement, the Preliminary Prospectus, the Prospectus and the Permitted Free Writing Prospectuses, if any, there has been any change or any development involving a prospective change in the business, properties, management, financial condition or results of operations of the Partnership and the Subsidiaries taken as a whole, the effect of which change or development is, in the sole judgment of the Representatives, so material and adverse as to make it impractical or inadvisable to proceed with the public offering or the delivery of the Units on the terms and in the manner contemplated in the Registration Statement, the Preliminary Prospectus, the Prospectus and the Permitted Free Writing Prospectuses, if any, or (ii) since the time of execution of this Agreement, there shall have occurred: (A) a suspension or material limitation in trading in securities generally on the NYSE, the NYSE MKT or the NASDAQ; (B) a suspension or material limitation in trading in the Partnership’s securities on the Primary Stock Exchange; (C) a general moratorium on commercial banking activities declared by either federal or New York State authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States; (D) an outbreak or escalation of hostilities or acts of terrorism involving the United States or a declaration by the United States of a national emergency or war; or (E) any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (A) through (E), is in the sole judgment of the Representatives, so material or adverse as to make it impractical or inadvisable to proceed with the public offering or the delivery of the Units on the terms and in the manner contemplated in the Registration Statement, the Preliminary Prospectus, the Prospectus and the Permitted Free Writing Prospectuses, if any, or (iii) since the time of execution of this Agreement, there shall have occurred any downgrading, or any notice or announcement shall have been given or made of: (X) any intended or potential downgrading or (Y) any watch, review or possible change that does not indicate an affirmation or improvement in the rating accorded any securities of or guaranteed by the Partnership or any Subsidiary by any “nationally recognized statistical rating organization,” as that term is defined in Section 3(a)(62) of the Exchange Act.

If the Representatives elect to terminate this Agreement as provided in this Section 7, the Partnership and each other Underwriter shall be notified promptly in writing.

If the sale to the Underwriters of the Units, as contemplated by this Agreement, is not carried out by the Underwriters for any reason permitted under this Agreement, or if such sale is not carried out because the Partnership shall be unable to comply with any of the terms of this Agreement, the Partnership shall not be under any obligation or liability under this Agreement (except to the extent provided in Sections 4(m), 5 and 9 hereof), and the Underwriters shall be under no obligation or liability to the Partnership under this Agreement (except to the extent provided in Section 9 hereof) or to one another hereunder.

8. Increase in Underwriters’ Commitments. Subject to Sections 6 and 7 hereof, if any Underwriter shall default in its obligation to take up and pay for the Firm Units to be purchased by it hereunder (otherwise than for a failure of a condition set forth in Section 6 hereof or a reason sufficient to justify the termination of this Agreement under the provisions of Section 7 hereof) and if the number of Firm Units which all Underwriters so defaulting shall

have agreed but failed to take up and pay for does not exceed 10% of the total number of Firm Units, the non-defaulting Underwriters (including the Underwriters, if any, substituted in the manner set forth below) shall take up and pay for (in addition to the aggregate number of Firm Units they are obligated to purchase pursuant to Section 1 hereof) the number of Firm Units agreed to be purchased by all such defaulting Underwriters, as hereinafter provided. Such Units shall be taken up and paid for by such non-defaulting Underwriters in such amount or amounts as the Representatives may designate with the consent of each Underwriter so designated or, in the event no such designation is made, such Units shall be taken up and paid for by all non-defaulting Underwriters pro rata in proportion to the aggregate number of Firm Units set forth opposite the names of such non-defaulting Underwriters in Schedule A.

Without relieving any defaulting Underwriter from its obligations hereunder, the Partnership agrees with the non-defaulting Underwriters that the Partnership will not sell any Firm Units hereunder unless all of the Firm Units are purchased by the Underwriters (or by substituted Underwriters selected by the Representatives with the approval of the Partnership or selected by the Partnership with the Representatives’ approval).

If a new Underwriter or Underwriters are substituted by the Underwriters or by the Partnership for a defaulting Underwriter or Underwriters in accordance with the foregoing provision, the Partnership or the Representatives shall have the right to postpone the time of purchase for a period not exceeding five business days in order that any necessary changes in the Registration Statement and the Prospectus and other documents may be effected.

The term “Underwriter” as used in this Agreement shall refer to and include any Underwriter substituted under this Section 8 with like effect as if such substituted Underwriter had originally been named in Schedule A hereto.

If the aggregate number of Firm Units which the defaulting Underwriter or Underwriters agreed to purchase exceeds 10% of the total number of Firm Units which all Underwriters agreed to purchase hereunder, and if neither the non-defaulting Underwriters nor the Partnership shall make arrangements within the five business day period stated above for the purchase of all the Firm Units which the defaulting Underwriter or Underwriters agreed to purchase hereunder, this Agreement shall terminate without further act or deed and without any liability on the part of the Partnership to any Underwriter and without any liability on the part of any non-defaulting Underwriter to the Partnership. Nothing in this paragraph, and no action taken hereunder, shall relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

9. Indemnity and Contribution.

(a) The Partnership agrees to indemnify, defend and hold harmless each Underwriter, its partners, directors and officers, and any person who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, selling agents, and any affiliates of such Underwriter who have, or who are alleged to have, participated in the distribution of the Units as underwriters (such affiliates being referred to herein as “Participating Affiliates”), and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim

(including the reasonable cost of investigation) which, jointly or severally, any such Underwriter or any such person may incur under the Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Partnership) or arises out of or is based upon any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as any such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information specified in Section 10 hereof furnished in writing by or on behalf of such Underwriter through the Representatives to the Partnership expressly for use in, the Registration Statement or arises out of or is based upon any omission or alleged omission to state a material fact in the Registration Statement in connection with such information, which material fact was not contained in such information and which material fact was required to be stated in the Registration Statement or was necessary to make such information not misleading or (ii) any untrue statement or alleged untrue statement of a material fact included in any Prospectus (the term Prospectus for the purpose of this Section 9 being deemed to include the Basic Prospectus, the Preliminary Prospectus, the Prospectus Supplement, the Prospectus and any amendments or supplements to the foregoing), in any Permitted Free Writing Prospectus, in any “issuer information” (as defined in Rule 433 under the Act) of the Partnership or in the Prospectus together with any combination of one or more of the Permitted Free Writing Prospectuses, if any, or arises out of or is based upon any omission or alleged omission 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, except, with respect to such Prospectus or Permitted Free Writing Prospectus, insofar as any such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information specified in Section 10 hereof furnished in writing by or on behalf of such Underwriter through the Representatives to the Partnership expressly for use in, such Prospectus or Permitted Free Writing Prospectus or arises out of or is based upon any omission or alleged omission to state a material fact in such Prospectus or Permitted Free Writing Prospectus in connection with such information, which material fact was not contained in such information and which material fact was necessary in order to make the statements in such information, in the light of the circumstances under which they were made, not misleading.

(b) Each Underwriter severally agrees to indemnify, defend and hold harmless the Partnership, its respective directors and officers, and any person who controls the Partnership within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, the Partnership or any such person may incur under the Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information specified in

Section 10 hereof furnished in writing by or on behalf of such Underwriter through the Representatives to the Partnership expressly for use in, the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Partnership), or arises out of or is based upon any omission or alleged omission to state a material fact in the Registration Statement in connection with such information, which material fact was not contained in such information and which material fact was required to be stated in the Registration Statement or was necessary to make such information not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information specified in Section 10 hereof furnished in writing by or on behalf of such Underwriter through the Representatives to the Partnership expressly for use in, the Prospectus or a Permitted Free Writing Prospectus, or arises out of or is based upon any omission or alleged omission to state a material fact in the Prospectus or Permitted Free Writing Prospectus in connection with such information, which material fact was not contained in such information and which material fact was necessary in order to make the statements in such information, in the light of the circumstances under which they were made, not misleading.

(c) If any action, suit or proceeding (each, a “Proceeding”) is brought against a person (an “indemnified party”) in respect of which indemnity may be sought against the Partnership or an Underwriter (as applicable, the “indemnifying party”) pursuant to subsection (a) or (b), respectively, of this Section 9, such indemnified party shall promptly notify such indemnifying party in writing of the institution of such Proceeding and such indemnifying party shall assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses; provided, however, that the omission to so notify such indemnifying party shall not relieve such indemnifying party from any liability which such indemnifying party may have to the indemnified party unless and to the extent it did not otherwise learn of such Proceeding and such omission results in the forfeiture by the indemnifying party of substantial rights and defenses, and will not, in any event, relieve the indemnifying party from any obligations to an indemnified party other than the indemnifying party’s indemnification obligations provided in (a) or (b) above. The indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless the employment of such counsel shall have been authorized in writing by the indemnifying party in connection with the defense of such Proceeding or the indemnifying party shall not have, within a reasonable period of time in light of the circumstances, employed counsel to defend such Proceeding or such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from, additional to or in conflict with those available to such indemnifying party (in which case such indemnifying party shall not have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by such indemnifying party and paid as incurred (it being understood, however, that such indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding). The indemnifying party shall not be liable for any settlement of any

Proceeding effected without its written consent but, if settled with its written consent, such indemnifying party agrees to indemnify and hold harmless the indemnified party or parties from and against any loss or liability by reason of such settlement. 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 the second sentence of this Section 9(c), then 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 60 business days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have fully reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 30 days’ prior notice of its intention to settle. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened Proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding and does not include an admission of fault or culpability or a failure to act by or on behalf of such indemnified party.

(d) If the indemnification provided for in this Section 9 is unavailable to an indemnified party under subsections (a) or (b) of this Section 9 or insufficient to hold an indemnified party harmless in respect of any losses, damages, expenses, liabilities or claims referred to therein, then each applicable indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, damages, expenses, liabilities or claims (i) in such proportion as is appropriate to reflect the relative benefits received by the Partnership, on the one hand, and the Underwriters, on the other hand, 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 Partnership, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, damages, expenses, liabilities or claims, as well as any other relevant equitable considerations. The relative benefits received by the Partnership, on the one hand, and the Underwriters, on the other hand, shall be deemed to be in the same respective proportions as the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Partnership, and the total underwriting discounts and commissions received by the Underwriters, bear to the aggregate public offering price of the Units. The relative fault of the Partnership and the Underwriters shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by the Partnership or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, damages, expenses, liabilities and claims referred to in this subsection shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating, preparing to defend or defending any Proceeding.

(e) The Partnership 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 subsection (d) above. Notwithstanding the provisions of this Section 9, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Units underwritten by such Underwriter and distributed to the public were offered to the public exceeds the amount of any damage which such Underwriter has otherwise been required to pay by reason of such untrue statement or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ and the Partnership’s respective obligations to contribute pursuant to this Section 9 are several in proportion to their respective underwriting commitments and sales commitments, respectively, and not joint.

(f) The indemnity and contribution agreements contained in this Section 9 and the covenants, warranties and representations of the Partnership contained in this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of any Underwriter, its partners, directors or officers, selling agents, or any person (including each partner, officer or director of such person), who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and Participating Affiliates or by or on behalf of the Partnership, its respective directors or officers, selling agents, or any person who controls the Partnership within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and shall survive any termination of this Agreement or the issuance and delivery of the Units. The Partnership and each Underwriter agree promptly to notify each other of the commencement of any Proceeding against it and, in the case of the Partnership, against any of the Partnership’s officers or directors in connection with the issuance and sale of the Units, or in connection with the Registration Statement, the Basic Prospectus, the Preliminary Prospectus, the Prospectus or any Permitted Free Writing Prospectus.

10. Information Furnished by the Underwriters. The statements set forth in the last paragraph on the cover page of the Prospectus and the statements set forth in (i) the first paragraph of the subsection entitled “Underwriting Discount and Expenses” and (ii) the subsection entitled “Price Stabilization, Short Positions and Penalty Bids,” in each case under the caption “Underwriting” in the Preliminary Prospectus and the Prospectus, only insofar as such statements relate to the amount of selling concession and reallowance or to stabilization activities that may be undertaken by the Underwriters, constitute the only information furnished by or on behalf of the Underwriters, as such information is referred to in Sections 3 and 9 hereof.

12. Governing Law; Construction. This Agreement and any claim, counterclaim or dispute of any kind or nature whatsoever arising out of or in any way relating to this Agreement (“Claim”), directly or indirectly, shall be governed by, and construed in accordance with, the Laws of the State of New York. The section headings in this Agreement have been inserted as a matter of convenience of reference and are not a part of this Agreement.

13. Submission to Jurisdiction. Except as set forth below, no Claim may be commenced, prosecuted or continued in any court other than the courts of the State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York, which courts shall have jurisdiction over the adjudication of such matters, and the Partnership consents to the jurisdiction of such courts and personal service with respect thereto. The Partnership hereby consents to personal jurisdiction, service and venue in any court in which any Claim arising out of or in any way relating to this Agreement is brought by any third party against any Underwriter or any indemnified party. Each Underwriter and the Partnership (on its behalf and, to the extent permitted by applicable Law, on behalf of its Unitholders and affiliates) waive all right to trial by jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. The Partnership agrees that a final judgment in any such action, proceeding or counterclaim brought in any such court shall be conclusive and binding upon the Partnership and may be enforced in any other courts to the jurisdiction of which the Partnership is or may be subject, by suit upon such judgment.

The foregoing sentence shall not apply to (a) the registration of the offer and sale of Common Units as contemplated by the Underwriting Agreement and the sale of the Common Units to the Underwriters (as defined in the Underwriting Agreement) in the Offering, (b) bona fide gifts, provided the recipient thereof agrees in writing with the Underwriters to be bound by the terms of this Lock-Up Agreement, (c) dispositions to any trust for the direct or indirect benefit of the undersigned and/or the immediate family of the undersigned, provided that such trust agrees in writing with the Underwriters to be bound by the terms of this Lock-Up Agreement, (d) the sale, assignment or transfer of Common Units or other Partnership securities in a private placement, provided the recipient thereof agrees in writing with the Underwriters to be bound by the terms of this Lock-Up Agreement, (e) the pledge of any Common Units or other Partnership securities to secure loans to such persons or entities in connection with any financing transaction to which such persons or entities are parties, provided that such Common Units or other Partnership securities may not be sold or disposed of in connection with the exercise by the lender of any remedies as a secured party until the expiration of the Lock-Up Period, (f) existing pledges pursuant to loan or similar agreements in effect on the date hereof, as amended from time to time, or any successor to any such agreement, or any transfers pursuant to any such agreement, (g) distributions to members, stockholders or partners, provided that the recipient of such Common Units or other class of Partnership securities agrees to be bound by the terms of this agreement for the remainder of the Lock-Up Period, (h) the deemed disposition of Common Units under Section 16 of the Exchange Act upon the cash settlement of phantom units or stock appreciation rights outstanding as of the date of this Agreement, and (i) the conversion of Class B Units or Waiver Units (each as defined in the Underwriting Agreement) into Common Units. For purposes of this paragraph, “immediate family” shall mean the undersigned and the spouse, any lineal descendent, father, mother, brother or sister of the undersigned.

OPINION OF AKIN GUMP ▇▇▇▇▇▇▇ ▇▇▇▇▇ & ▇▇▇▇, LLP

1.	(a) The General Partner is validly existing as a limited liability company and is in good standing under the laws of the State of Delaware.

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

All outstanding Common Units, Class B Units and Waiver Units and, in each case, the limited partner interests represented thereby have been duly authorized and validly issued in accordance with the Partnership Agreement, and are fully paid (to the extent required under the Partnership Agreement) and nonassessable (except as such nonassessability may be affected by Sections 17-303, 17-607 and 17-804 of the Delaware Revised Uniform Limited Partnership Act (the “Delaware LP Act”)).

The Units to be issued and sold to the Underwriters by the Partnership pursuant to the Underwriting Agreement and the limited partner interests represented thereby have been duly authorized in accordance with the Partnership Agreement and, when issued and delivered to the Underwriters against payment therefor in accordance with the terms of the Underwriting Agreement, will be validly issued, fully paid (to the extent required under the Partnership Agreement) and nonassessable (except as such nonassessability may be affected by Sections 17-303, 17-607 and 17-804 of the Delaware LP Act).

B-1-1

The General Partner (i) is the sole general partner of the Partnership and owns (of record) a non-economic general partner interest in the Partnership and (ii) is the sole general partner of Genesis Crude Oil, L.P., a Delaware limited partnership (the “Operating Partnership”) and owns (of record) a 0.01% general partner interest in the Operating Partnership. The General Partner owns a non-economic general partner interest in Genesis Pipeline USA, L.P. Other than the general partner interests described in the preceding sentences, the Partnership, directly or indirectly, owns (of record) 100% of the limited partner interest, limited liability company interest or other equity interest in each Significant Subsidiary. Each such general partner interest, limited partner interest, limited liability company interest and other equity interest has been duly authorized and validly issued in accordance with the Constitutive Documents of the Partnership and each respective Significant Subsidiary, is fully paid (to the extent required under its respective Constitutive Documents) and non-assessable (except (x) with respect to those Significant Subsidiaries that are Delaware limited partnerships, as such nonassessability may be affected by Sections 17-303, 17-607 and 17-804 of the Delaware LP Act, (y) with respect to those Significant Subsidiaries that are Delaware limited liability companies, as such nonassessability may be affected by Sections 18-607 and 18-804 of the Delaware Limited Liability Company Act (the “Delaware LLC Act”), or (z) with respect to Fuel Masters, as such nonassessability may be affected by Sections 101.206 and 101.613 of the Texas Business Organizations Code (the “Texas BOC”)), and, in each case, is owned as specified in the three preceding sentences, free and clear of all liens, encumbrances, security interests, charges or claims (i) in respect of which a financing statement under the Uniform Commercial Code of the State of Delaware or the State of Texas (with respect to equity interests owned by Fuel Masters) naming the General Partner, the Partnership or any Significant Subsidiary as a “debtor” was on file as of September , 2013 in the office of the Secretary of State of the State of Delaware or as of September , 2013 in the office of the Secretary of State of the State of Texas (with respect to equity interests owned by Fuel Masters) or (ii) otherwise known to us, in the case of (i) and (ii), other than those (A) created under the Delaware LP Act, the Delaware LLC Act, the Delaware General Corporation Law (the “DGCL”) or the Texas BOC, (B) created in connection with the Partnership’s or the Significant Subsidiaries’ credit facilities constituting SEC Documents, (C) created by the Constitutive Documents of the Partnership Entities, or (D) as disclosed in the Preliminary Prospectus Supplement and the Final Prospectus Supplement.

Except as described in the Preliminary Prospectus and the Prospectus or, in the case of transfer restrictions, options to purchase, other rights to subscribe or to purchase, voting restrictions and preemptive rights, created by the Constitutive Documents of any Partnership Entity, there are no options, warrants, preemptive rights or other rights to subscribe for or to purchase, nor any restriction upon the voting or transfer of, any equity interests in any Partnership Entity pursuant to any Constitutive Document of any Partnership Entity or any other SEC Document, other than those restrictions upon the transfer of equity interests created in connection with the Partnership’s or the Significant Subsidiaries’ credit facilities constituting SEC Documents. Neither (i) the filing of the Registration Statement nor (ii) the offering or sale of the Units as contemplated by the Underwriting Agreement gives rise under any SEC Document to any rights for or relating to the registration under the Act of any Common Units or other securities of any Partnership Entity other than those that either have been waived or are described in the Preliminary Prospectus and the Prospectus.

B-1-2

6.	The Partnership has all requisite partnership power and authority to issue, sell and deliver the Units, in accordance with and upon the terms and conditions set forth in the Underwriting Agreement and the Partnership Agreement.

7.	The Underwriting Agreement has been duly authorized, executed and delivered by the Partnership.

8.	The Partnership Agreement has been duly authorized, executed and delivered by the General Partner and is a valid and legally binding agreement of the General Partner, enforceable against the General Partner in accordance with its terms.

None of the offering, issuance and sale by the Partnership of the Units, the execution, delivery and performance of the Underwriting Agreement by the Partnership or the performance of the actions required to be taken by the Partnership pursuant to the Underwriting Agreement conflicts or will conflict with or constitute or will constitute a breach or violation of or a default (or an event which, with notice or lapse of time or both, would constitute such a default) under, or results or will result in the creation or imposition of any lien, charge, claim, encumbrance or other security interest upon any property or assets of any of the Partnership Entities (other than those created in connection with the Partnership’s or the Significant Subsidiaries’ credit facilities constituting SEC Documents) pursuant to, (i) any Constitutive Document of any of the Partnership Entities, (ii) any SEC Document, (iii) the Delaware LP Act, the DGCL, the Delaware LLC Act, the laws of the State of Texas or federal law or (iv) any order, judgment, decree or injunction of any court or governmental agency or body known to us directed to any of the Partnership Entities or any of their properties in a proceeding to which any of them or their property is a party; provided, however, that no opinion is expressed pursuant to this paragraph with respect to federal securities laws and other anti-fraud laws.

10.

No permit, consent, approval, authorization, order, registration, filing or qualification (“consent”) of or with any court or governmental agency or body under the Delaware LP Act, the Delaware LLC Act, the DGCL, Texas law or federal law is required in connection with the offering, issuance and sale by the Partnership of the Units, the execution, delivery and performance of the Underwriting Agreement by the Partnership or the performance of the actions required to be taken by the Partnership pursuant to the Underwriting Agreement, other than (i) such consents required under state securities or “Blue Sky” laws, (ii) such consents that have been obtained or made, and (iii) filings with the Commission required in the performance by the Partnership of its obligations under Sections 4(b), (c), (f), (g), (h) and (n) of the Underwriting Agreement.

11.

The statements set forth in the Preliminary Prospectus and the Prospectus under the captions “Price Range of Common Units and Distributions,” “Description of Our Equity Securities—Our Common Units,” “Cash Distribution Policy,” “Description of Our Partnership Agreement,” “Material Tax Considerations” and “Material Income Tax

B-1-3

Consequences,” insofar as they summarize any agreement, statute or regulation or refer to statements of law or legal conclusions, are accurate and fair summaries in all material respects; and the Common Units (including the Units) conform in all material respects to the descriptions thereof contained in the Preliminary Prospectus and the Prospectus under the captions “Price Range of Common Units and Distributions,” “Description of Our Equity Securities—Our Common Units,” “Cash Distribution Policy,” and “Description of Our Partnership Agreement.”

12.

The Registration Statement was declared effective under the Act on April 23, 2012; to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or threatened by the SEC; and any required filing of the Prospectus pursuant to Rule 424(b) has been made in the manner and within the time period required by such Rule.

13.	None of the Partnership Entities is an “investment company,” within the meaning of the Investment Company Act.

For purposes of this letter, we have assumed the information in the 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 such 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 and the Prospectus are of a wholly or partially non-legal character, except as expressly set forth in paragraph (11) 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 Prospectus, 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 Prospectus 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.

B-1-4

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) The Registration Statement (as of the date of the Underwriting Agreement), the Preliminary Prospectus (as of its date) and the Prospectus (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. 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 under the Act that are required to be (but are not) summarized in the Preliminary Prospectus or the Prospectus, 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.

(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 8:15 a.m. (New York time) on September 11, 2013 (which you have informed us is a time prior to the time of the first sale of the Units by any Underwriters), 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.

When used in this opinion letter, the phrases “known to us”, “to our actual knowledge” and similar phrases (i) mean the actual knowledge of facts or other information by (a) the lawyer in our firm who signed this opinion letter, (b) any lawyer in our firm actively involved in negotiating and preparing the Underwriting Agreement, the Registration Statement, the Preliminary Prospectus Supplement or the Final Prospectus Supplement, (c) solely as to information relevant to a particular opinion, issue or confirmation regarding a particular factual matter, any lawyer in our firm who is primarily responsible for that particular opinion, issue or

B-1-5

confirmation and (d) any lawyer in our firm actively involved in matters involving the Partnership Entities during the past twenty-four months, and (ii) do not require or imply that any inquiry be made of the client, any lawyer (other than the lawyers described above), or any other person or entity, other than as described in the fourth paragraph of such opinion letter.

▇-▇-▇

▇▇▇▇▇▇▇ ▇-▇

OPINION OF ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇

To my knowledge, there are no legal or governmental proceedings pending or threatened to which any of the Partnership Entities is a party or to which any of their respective properties is subject that are required to be described in the Preliminary Prospectus or the Prospectus but are not so described as required.

▇-▇-▇

▇▇▇▇▇▇▇ ▇-▇

OPINION OF LISKOW & ▇▇▇▇▇

1.	Red River Terminals, L.L.C. is a limited liability company duly organized, validly existing and in good standing under the laws of the State of Louisiana. TDC, L.L.C. is a limited liability company validly existing and in good standing under the laws of the State of Louisiana.

2.	Each of Red River Terminals, L.L.C. and TDC, L.L.C. has the power and authority to own its respective properties and conduct its business in each case in all material respects, as described in the Preliminary Prospectus and the Prospectus.

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 respective articles of organization of Red River Terminals, L.L.C. and TDC, L.L.C. or the Operating Agreement of TDC, L.L.C. and the Amended and Restated Operating Agreement of Red River Terminals, L.L.C., as subsidiaries of the Partnership.

4.	The membership interests of Red River Terminals, L.L.C. and TDC, L.L.C. are validly authorized, issued, fully paid, non-assessable equity interests.

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 respective articles of organization of Red River Terminals, L.L.C. and TDC, L.L.C., the Amended and Restated Operating Agreement of Red River Terminals, L.L.C., or the laws of the State of Louisiana.

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 Red River Terminals, L.L.C. and TDC, L.L.C., does 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.
