Upon the basis of the representations and warranties and subject to the terms and conditions herein set forth, the Partnership agrees to issue and sell, and the Selling Unitholders agree to sell, severally and not jointly, to the respective Underwriters, and each of the Underwriters, severally and not jointly, agrees to purchase from the Partnership and the Selling Unitholders the number of Firm Units set forth opposite the name of such Underwriter inSchedule A attached hereto, subject to adjustment in accordance withSection 10 hereof, in each case at a purchase price of $25.23 per Unit. The Partnership and the Selling Unitholders are advised by the Representatives that the Underwriters intend (i) to make a public offering of their respective portions of the Firm Units as soon after the effectiveness of this Agreement as in the Representatives’ judgment is advisable and (ii) initially to offer the Firm Units upon the terms set forth in the Prospectus. 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 and the Selling Unitholders hereby grant 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 and the Selling Unitholders, 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 and the Selling Unitholders 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 and the Selling Unitholders. Such notice shall set forth the aggregate number of Additional Units as to which the Over-Allotment Option is being exercised and the date and time when the Additional Units are to be delivered (any such date and time being herein referred to as an “additional time of purchase”);provided,however, that no additional time of purchase shall be earlier than the “time of purchase” (as defined below) nor earlier than the second business day after the date on which the Over-Allotment Option shall have been exercised nor later than the tenth business day after the date on which the Over-Allotment Option shall have been exercised. The number of Additional Units to be sold to each Underwriter shall be the number which bears the same proportion to the aggregate number of Additional Units being purchased as the number of Firm Units set forth opposite the name of such Underwriter onSchedule A hereto bears to the total number of Firm Units (subject, in each case, to such adjustment as the Representatives may determine to eliminate fractional units), subject to adjustment in accordance withSection 10 hereof. With respect to each exercise of the Over-Allotment Option, the Partnership shall sell two-thirds of such Additional Units and the Selling Unitholders shall sell one-third of such Additional Units (in the respective amounts and percentages set forth on Schedule B) to the Underwriters (subject, in each case, to such adjustment as the Representatives may determine to eliminate fractional units).

2.Payment and Delivery. Payment of the purchase price for the Firm Units shall be made to the Partnership and each of the Selling Unitholders to the account or accounts of the Partnership and such Selling Unitholder as specified onSchedule E hereto, by Federal Funds wire transfer against delivery of the Firm Units to Wells Fargo through the facilities of The Depository Trust Company (“DTC”) for the respective accounts of the Underwriters. Such payment and delivery shall be made at 10:00 A.M., New York City time, on July 20, 2011 (unless another time shall be agreed to by the Representatives, the Partnership and the Selling Unitholders or unless postponed in accordance with the provisions ofSection 10 hereof). The time at which such payment and delivery are to be made is hereinafter sometimes called the “time of purchase.” Electronic transfer of the Firm Units shall be made to Wells Fargo at the time of purchase in such names and in such denominations as Wells Fargo shall specify.

Payment of the purchase price for the Additional Units shall be made at the additional time of purchase in the same manner and at the same office as the payment for the Firm Units. Electronic transfer of the Additional Units shall be made to Wells Fargo at the additional time of purchase in such names and in such denominations as Wells Fargo shall specify.

Deliveries of the documents described inSection 8 hereof with respect to the purchase of the Units shall be made at the offices of Akin Gump Strauss Hauer & Feld LLP, at 1111 Louisiana Street, 44th Floor, Houston, Texas, at 10:00 A.M., New York City time, on the date of the closing of the purchase of the Firm Units or the Additional Units, as the case may be.

If the Representatives elect to terminate this Agreement as provided in thisSection 9, the Partnership, the Selling Unitholders 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 or the Selling Unitholders shall be unable to comply with any of the terms of this Agreement, the Partnership and the Selling Unitholders shall not be under any obligation or liability under this Agreement (except to the extent provided inSections 5(m),7 and11 hereof), and the Underwriters shall be under no obligation or liability to the Partnership or the Selling Unitholders under this Agreement (except to the extent provided inSection 11 hereof) or to one another hereunder.

10.Increase in Underwriters’ Commitments. Subject toSections 8 and9 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 inSection 8 hereof or a reason sufficient to justify the termination of this Agreement under the provisions ofSection 9 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 toSection 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 inSchedule A.

Without relieving any defaulting Underwriter from its obligations hereunder, the Partnership and the Selling Unitholders each agree with the non-defaulting Underwriters that it 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 Statements 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 thisSection 10 with like effect as if such substituted Underwriter had originally been named inSchedule 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 or the Selling Unitholders to any Underwriter and without any liability on the part of any non-defaulting Underwriter to the Partnership or the Selling Unitholders. 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.

11.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 either of the Registration Statements (or in a 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 inSection 12 hereof furnished in writing by or on behalf of such Underwriter through the Representatives to the Partnership expressly for use in, the applicable Registration Statement or arises out of or is based upon any omission or alleged omission to state a material fact in either of the Registration Statements in connection with such information, which material fact was not contained in such information and which material fact was required to be stated in either of the Registration Statements 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 thisSection 11 being deemed to include any Basic Prospectus, any 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 any 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 inSection 12 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 Selling Unitholder severally agrees to indemnify, defend and hold harmless each Underwriter and the Partnership, their partners, directors and officers, selling agents, and any person who controls any Underwriter or the Partnership within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and any 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 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 either of the Registration Statements (or in a Registration Statement as amended by any post-effective amendment thereof by the Partnership), in any Prospectus, in any Permitted Free Writing Prospectus, 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 (in light of the circumstances in which they were made, in the case of any Prospectus or any Free Writing Prospectus) not misleading, which material fact was required to be stated therein or not contained therein and which material fact was necessary in order to make the statements therein (in light of the circumstances in which they were made, in the case of any Prospectus or any Free Writing Prospectus) not misleading, but only with respect to any untrue statement or omission, or alleged untrue statement or omission, made in reliance upon and in conformity with information furnished or confirmed in writing to the Partnership by or on behalf of such Selling Unitholder expressly for use therein, which information is limited to the information with respect to such Selling Unitholder set forth in the Preliminary Prospectus and the applicable Prospectus under the caption “Selling Unitholders,” or (ii) any untrue statement or alleged untrue statement of a material fact included in any Permitted Free

Writing Prospectus, in any “issuer information” (as defined in Rule 433 under the Act) used or referred to in any “free writing prospectus” (as defined in Rule 405 under the Act), prepared by or on behalf of such Selling Unitholder or used or referred to by such Selling Unitholder in connection with the offering of the Units in violation ofSection 6(b) (a “Selling Unitholder Free Writing Prospectus”), 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, but only with respect to any untrue statement or omission, or alleged untrue statement or omission, made in reliance upon and in conformity with information furnished or confirmed in writing to the Partnership by or on behalf of such Selling Unitholders expressly for use therein. The liability of the Selling Unitholder under the indemnity agreement contained in this paragraph shall be limited to an amount equal to the total gross proceeds from the offering of the Units purchased under this Agreement received by the Selling Unitholder, after payment of underwriting discounts and commissions but before payment of offering expenses.

(c) Each Underwriter severally agrees to indemnify, defend and hold harmless the Partnership and each Selling Unitholder, their respective directors and officers, and any person who controls the Partnership or such Selling Unitholder 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, such Selling Unitholder 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 inSection 12 hereof furnished in writing by or on behalf of such Underwriter through the Representatives to the Partnership expressly for use in, the applicable Registration Statement (or in a 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 applicable 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 applicable 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 inSection 12 hereof furnished in writing by or on behalf of such Underwriter through the Representatives to the Partnership expressly for use in, a 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 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.

(d) 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, a Selling Unitholder or an Underwriter (as applicable, the “indemnifying

party”) pursuant to subsection (a), (b) or (c), respectively, of thisSection 11, 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), (b) or (c) 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 thisSection 11(d), 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.

(e) If the indemnification provided for in thisSection 11 is unavailable to an indemnified party under subsections (a), (b) or (c) of thisSection 11 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 and the Selling Unitholders, 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 and the Selling Unitholders, 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 and the Selling Unitholders, 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 Selling Unitholders, 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, the Selling Unitholders 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 and the Selling Unitholders 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.

(f) The Partnership, the Selling Unitholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to thisSection 11 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 (e) above. Notwithstanding the provisions of thisSection 11, 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’, the Partnership’s and the Selling Unitholders’ respective obligations to contribute pursuant to thisSection 11 are several in proportion to their respective underwriting commitments and sales commitments, respectively, and not joint.

(g) The indemnity and contribution agreements contained in thisSection 11 and the covenants, warranties and representations of the Partnership and the Selling Unitholders 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 or the Selling Unitholders, their 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, each Selling Unitholder and each Underwriter agree promptly to notify each other of the commencement of any Proceeding against it and, in the case of the Partnership and the Selling Unitholders, against any of the Partnership’s or any Selling Unitholder’s officers or directors in connection with the issuance and sale of the Units, or in connection with the applicable Registration Statement, any Basic Prospectus, any Preliminary Prospectus, the Prospectus or any Permitted Free Writing Prospectus.

12.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 any 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 inSections 3 and11 hereof.

13.Notices. Except as otherwise herein provided, all statements, requests, notices and agreements shall be in writing or by telegram or facsimile and, if to the Underwriters, shall be sufficient in all respects if delivered or sent to Wells Fargo Securities, LLC, 375 Park Avenue, 4th Floor, New York, New York 10152, Attention: Equity Syndicate Department; Merrill Lynch, Pierce, Fenner & Smith Incorporated, One Bryant Park, New York, New York 10036, Attention: Syndicate Department; Citigroup Global Markets Inc., 388 Greenwich Street, New York, New York 10013, Attention: General Counsel (Fax no.

14.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.

15.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 and each of the Selling Unitholders consent to the jurisdiction of such courts and personal service with respect thereto. The Partnership and each of the Selling Unitholders hereby consent 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, each Selling Unitholder 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 and each of the Selling Unitholders agree that a final judgment in any such action, proceeding or counterclaim brought in any such court shall be conclusive and binding upon the Partnership or such Selling Unitholder, as applicable, and may be enforced in any other courts to the jurisdiction of which the Partnership or such Selling Unitholder is or may be subject, by suit upon such judgment.

16.Parties at Interest. The Agreement herein set forth has been and is made solely for the benefit of the Underwriters, the Partnership and the Selling Unitholders and to the extent provided inSection 11 hereof the selling agents, controlling persons, partners, directors and officers referred to in such Section, and their respective successors, assigns, heirs, personal representatives and executors and administrators. No other person, partnership, association or corporation (including a purchaser, as such purchaser, from any of the Underwriters) shall acquire or have any right under or by virtue of this Agreement.

17.No Fiduciary Relationship. The Partnership and the Selling Unitholders hereby acknowledge that the Underwriters are acting solely as underwriters in connection with the purchase and sale of the Units. The Partnership and the Selling Unitholders further acknowledge that the Underwriters are acting pursuant to a contractual relationship created solely by this Agreement entered into on an arm’s length basis, and in no event do the parties intend that the Underwriters act or be responsible as a fiduciary to the Partnership, the Selling Unitholders, their respective management, security holders or creditors or any other person in connection with any activity that the Underwriters may undertake or have undertaken in furtherance of the purchase and sale of the Units, either before or after the date hereof. The Underwriters hereby expressly disclaim any fiduciary or similar obligations to the Partnership and the Selling Unitholders, either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and the Partnership and each of the Selling Unitholders hereby confirm its understanding and agreement to that effect. The Partnership, the Selling Unitholders and the Underwriters agree that they are each responsible for making their own independent judgments with respect to any such transactions and that any opinions or views expressed by the Underwriters to the Partnership and the Selling Unitholders regarding such transactions, including, but not limited to, any opinions or views with respect to the price or market for the

Units, do not constitute advice or recommendations to the Partnership or the Selling Unitholders. The Partnership and each of the Selling Unitholders hereby waive and release, to the fullest extent permitted by Law, any claims that the Partnership or such Selling Unitholder may have against the Underwriters with respect to any breach or alleged breach of any fiduciary or similar duty to the Partnership or such Selling Unitholder in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions.

18.Counterparts. This Agreement may be signed by the parties in one or more counterparts which together shall constitute one and the same agreement among the parties.

19.Successors and Assigns. This Agreement shall be binding upon the Underwriters, the Partnership and the Selling Unitholders and their successors and assigns and any successor or assign of any substantial portion of the Partnership’s, such Selling Unitholder’s and any of the Underwriters’ respective businesses and/or assets.

20.Miscellaneous. UBS, an indirect, wholly owned subsidiary of UBS AG, is not a bank and is separate from any affiliated bank, including any U.S. branch or agency of UBS AG. Because UBS is a separately incorporated entity, it is solely responsible for its own contractual obligations and commitments, including obligations with respect to sales and purchases of securities. Securities sold, offered or recommended by UBS are not deposits, are not insured by the Federal Deposit Insurance Corporation, are not guaranteed by a branch or agency, and are not otherwise an obligation or responsibility of a branch or agency.

Ladies and Gentlemen:

This Lock-Up Agreement is being delivered to you in connection with the proposed Underwriting Agreement (the “Underwriting Agreement”) to be entered into by Genesis Energy, L.P., a Delaware limited partnership (the “Partnership”), Quintana Energy Partners II, L.P., a

A-1

Cayman Islands limited partnership (“Quintana”), QEP II Genesis TE Holdco, LP, a Delaware limited partnership (“QEP”), EIV Capital Fund, LP, a Delaware limited partnership (“EIV” and, collectively with Quintana and QEP, the “Selling Unitholders”), Wells Fargo Securities, LLC (“Wells Fargo”), Merrill Lynch, Pierce, Fenner & Smith Incorporated, Citigroup Global Markets Inc., Deutsche Bank Securities Inc., RBC Capital Markets, LLC and UBS Securities LLC (collectively with Wells Fargo, the “Representatives”) and the other underwriters named inSchedule A to the Underwriting Agreement, with respect to the public offering (the “Offering”) of common units representing limited partner interests in the Partnership (the “Common Units”).

In order to induce the Representatives to enter into the Underwriting Agreement, the undersigned agrees that, for a period (the “Lock-Up Period”) beginning on the date hereof and ending on, and including, the date that is 45 days after the date of the final prospectus supplement relating to the Offering, the undersigned will not, without the prior written consent of Wells Fargo, (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or file (or participate in the filing of) a registration statement with the Securities and Exchange Commission (the “Commission”) in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission promulgated thereunder (the “Exchange Act”) with respect to, any Common Units or any other securities of the Partnership that are substantially similar to Common Units, or any securities convertible into or exchangeable or exercisable for, or any warrants or other rights to purchase, the foregoing, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of Common Units or any other securities of the Partnership that are substantially similar to Common Units, or any securities convertible into or exchangeable or exercisable for, or any warrants or other rights to purchase, the foregoing, whether any such transaction is to be settled by delivery of Common Units or such other securities, in cash or otherwise or (iii) publicly announce an intention to effect any transaction specified in clause (i) or (ii). 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

A-2

to be bound by the terms of this agreement for the remainder of the Lock-Up Period, or (h) the conversion of Class B Units or Waiver Units (each as defined in the Underwriting Agreement) into Common Units.

The General Partner is the sole general partner of (i) the Partnership and owns (of record) a non-economic general partner interest in the Partnership and (ii) 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.

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 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 Partnership Registration Statement and the Selling Unitholder Registration Statement nor

B-1-2

(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.

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

7.	Each of the Underwriting Agreement and the Purchase 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 Partnership Units, the offering and sale by the Selling Unitholders of the Selling Unitholder 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 constitutes 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.

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 Income Tax Consequences” and “Material Tax Considerations,” 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 Partnership Registration Statement was declared effective under the Act on August 6, 2010, and the Selling Unitholder registration statement was declared effective under the Act on April 25, 2011; to our knowledge, no stop order suspending the effectiveness of the Registration Statements 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 that each of the Preliminary Prospectus and the Prospectus was deemed to be a part of and included in the applicable Registration Statement pursuant to Rule 430B(f)(1) under the Act as of the date of the Underwriting Agreement. 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 applicable Registration Statement, the Preliminary Prospectus and the Prospectus are of a wholly or partially nonlegal character, except as expressly set forth in paragraph 11 of this letter and paragraphs (a) and (b) set forth below, 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 applicable Registration Statement, the Preliminary Prospectus, the Prospectus and the Disclosure Package 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 applicable 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

B-1-4

accountants for the Partnership, representatives of the Selling Unitholders, 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 Statements (as of their respective effective date), 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 data included or incorporated by reference in the applicable 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 data 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 as exhibits to the applicable Registration Statement and are not so filed, or of any documents that are required to be (but are not) summarized in the Preliminary Prospectus Supplement or the Final Prospectus Supplement.

(b) No information has come to our attention that causes us to believe that (i) the Registration Statements (as of their respective effective dates) 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 7:00 a.m. (Houston Time) on July 15, 2011 (which you have informed us is a time prior to the time of the first sale of the Units 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, financial schedules and other financial and accounting data contained or incorporated by reference therein.

When used in this opinion letter, the phrases “known to us”, “to our actual knowledge” and similar phrases 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 Statements, 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

B-1-5

matter, any lawyer in our firm who is primarily responsible for that particular opinion, issue or confirmation and (d) any lawyer in our firm actively involved in matters involving the Partnership Entities during the past twenty-four months.

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.

OPINION OF VINSON & ELKINS L.L.P.

1. Each of QEP II Genesis TE Holdco, LP and EIV Capital Fund LP (each a “Delaware Selling Unitholder”) is validly existing as a limited partnership and is in good standing under the laws of the State of Delaware.

2. Each Delaware Selling Unitholder has the requisite limited partnership power and authority to sell and deliver its respective Selling Unitholder Units in accordance with and upon the terms and conditions set forth in the Underwriting Agreement and the Partnership Agreement. All limited partnership action required to be taken by each Delaware Selling Unitholder for (i) the sale and delivery of the Selling Unitholder Units, (ii) the execution and delivery of the Underwriting Agreement and (iii) the consummation of the transactions contemplated by the Underwriting Agreement has been validly taken.

3. The Underwriting Agreement has been duly authorized, executed and delivered by each Delaware Selling Unitholder.

4. The Selling Unitholder Units owned by the Selling Unitholders are owned free and clear of all Liens (i) in respect of which a financing statement under the Uniform Commercial Code of the State of Delaware naming any Selling Unitholder as debtor is on file with the Secretary of State of the State of Delaware, or (ii) otherwise known to us, without independent investigation, other than those created by or arising under the Delaware LP Act or contained in the Partnership Agreement.

5. Upon the payment of the consideration for the Selling Unitholder Units to be sold by such Selling Unitholder and the crediting of such Selling Unitholder Units to the “security account” (within the meaning of Section 8-501(a) of the New York Uniform Commercial Code (the “UCC”)) of each of the Underwriters maintained in the records of DTC, each of the Underwriters will become an “entitlement holder” (within the meaning of Section 8-102(a)(7) of the UCC) of the “financial asset” (within the meaning of Section 8-102(a)(9) of the UCC) comprising the Selling Unitholder Units purchased by it from such Selling Unitholder, and, assuming that none of the Underwriters has “notice of an adverse claim” (within the meaning of Section 8-105 of the UCC) with respect to such Selling Unitholder Units, each of the Underwriters will acquire a “security entitlement” (within the meaning of Section 8-102(a)(17) of the UCC) to the Selling Unitholder Units purchased by such Underwriter from such Selling Unitholder). In giving this opinion, we have assumed that when such payment, delivery and crediting occur, (i) such Selling Unitholder Units will have been registered in the name of Cede & Co. or another nominee designated by DTC, in each case on the Partnership’s unit registry in accordance with the Partnership’s organizational documents and applicable law, (ii) DTC will be registered as a “clearing corporation” within the meaning of Section 8-102 of the UCC, and (iii) appropriate book entries to the accounts of the several Underwriters on the records of DTC will have been made pursuant to the UCC.

6. None of the execution, delivery and performance of the Underwriting Agreement by the Delaware Selling Unitholders (i) constitutes or will constitute a violation of the certificate of limited partnership or limited partnership agreement of the applicable Delaware Selling Unitholder. None of the execution, delivery and performance of the Underwriting Agreement by the Selling Unitholders (i) constitutes or will constitute a breach or violation

B-4-1

of or a default under (or an event that, with notice and lapse of time or both, would constitute such a breach or violation of or default under), any agreement filed as an exhibit to the Registration Statement or as an exhibit to the Partnership’s Form 10-K for the year ended December 31, 2010 or any reports filed subsequent to December 31, 2010 under the Exchange Act by the Partnership in each case to which any Selling Unitholder is a party or (ii) violates or will violate the Delaware LP Act, the laws of the State of New York or the federal laws of the United States of America, excluding in the case of clauses (i) and (ii) any such breaches, violations and defaults that would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on such Selling Unitholder or materially impair the ability of the Selling Unitholders to perform their obligations under the Underwriting Agreement; provided, however, that for purposes of this paragraph, we express no opinion with respect to federal or state securities laws or any antifraud laws.

7. No consent, approval, authorization or order of, or registration, filing or qualification with, any court or governmental agency or body of the State of New York, the State of Delaware or the United States of America (a “consent”) is required to be obtained or made by the Selling Unitholders under the Delaware LP Act, the laws of the State of New York or the federal laws of the United States of America in connection with the execution, delivery and performance of the Underwriting Agreement by the Selling Unitholders or the consummation of the transactions contemplated by the Underwriting Agreement by the Selling Unitholders, except for (i) such consents required under state or federal securities laws or “Blue Sky” laws, as to which we express no opinion, (ii) such consents that have been obtained or made or (iii) such consents which, if not obtained, would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on such Selling Unitholders or materially impair the ability of the Selling Unitholders to perform their obligations under the Underwriting Agreement.

In rendering such opinion, such counsel may state that its opinion is limited to matters governed by the federal laws of the United States of America, the laws of the State of New York and the Delaware LP Act.
