Subsidiaries taken as a whole, the effect of which change or development is, in the sole judgment of the Underwriter, 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 Underwriter, 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 Rule 436(g)(2) under the Act.

(c) The Underwriter 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 in Section 11 hereof furnished in writing by or on behalf of the Underwriter 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 11 hereof furnished in writing by or on behalf of the Underwriter 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.

(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 the Underwriter (as applicable, the “indemnifying party”) pursuant to subsection (a), (b) or (c), respectively, of this Section 10, 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 this Section 10(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 this Section 10 is unavailable to an indemnified party under subsections (a), (b) or (c) of this Section 10 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 Underwriter, 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 Underwriter, 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 Underwriter, 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 Underwriter, bear to the aggregate public offering price of the Units. The relative fault of the Partnership, the Selling Unitholders and the Underwriter 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 Underwriter 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 Underwriter agree that it would not be just and equitable if contribution pursuant to this Section 10 were determined by pro rata allocation 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 this Section 10, 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 the Underwriter and distributed to the public were offered to the public exceeds the amount of any damage which the 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 Underwriter’s, the Partnership’s and the Selling Unitholders’ respective obligations to contribute pursuant to this Section 10 are several in proportion to their respective underwriting commitments and sales commitments, respectively, and not joint.

(g) The indemnity and contribution agreements contained in this Section 10 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 the Underwriter, its partners, directors or officers, selling agents, or any person (including each partner, officer or director of such person), who controls the 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 the 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 Registration Statement, the Basic Prospectus, the Preliminary Prospectus, the Prospectus or any Permitted Free Writing Prospectus.

11. Information Furnished by the Underwriter. 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 and Short Positions,” 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 Underwriter, constitute the only information furnished by or on behalf of the Underwriter, as such information is referred to in Sections 3 and 10 hereof.

12. Notices.

13. 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.

14. 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 the Underwriter or any indemnified party. The 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.

15. Parties at Interest. The Agreement herein set forth has been and is made solely for the benefit of the Underwriter, the Partnership and the Selling Unitholders and to the extent provided in Section 10 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 the Underwriter) shall acquire or have any right under or by virtue of this Agreement.

16. No Fiduciary Relationship. The Partnership and the Selling Unitholders hereby acknowledge that the Underwriter is acting solely as an underwriter in connection with the purchase and sale of the Units. The Partnership and the Selling Unitholders further acknowledge that the Underwriter is 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 Underwriter 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 Underwriter may undertake or have undertaken in furtherance of the purchase and sale of the Units, either before or after the date hereof. The Underwriter hereby expressly disclaims 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 Underwriter 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 Underwriter 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 Underwriter 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.

17. 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.

This Agreement shall be binding upon the Underwriter, 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 Underwriter’s business and/or assets.

Barclays Capital Inc.

000 Xxxxxxx Xxxxxx

Xxx Xxxx, Xxx Xxxx 00000

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”), the Selling Unitholders named in Schedule A to the Underwriting Agreement (collectively, the “Selling Unitholders”), and Barclays Capital Inc. (the “Underwriter”), 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 Underwriter 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 the Underwriter, (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 Underwriter (as defined in the Underwriting Agreement) in the Offering, (b) bona fide gifts, provided the recipient thereof agrees in writing with the Underwriter 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 Underwriter 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 Underwriter to be bound by the terms of this Lock-Up Agreement, (e) the pledge of any

A-1

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 (or any such pledges made in connection with the purchase by the undersigned of any Common Units or Class B Units under the Purchase Agreement (as defined in the Underwriting Agreement)), 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 or (h) 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.

The undersigned further agrees that, for the Lock-Up Period, the undersigned will not, without the prior written consent of the Underwriter, make any demand for, or exercise any right with respect to, the registration of Common Units or any securities convertible into or exercisable or exchangeable for Common Units, or warrants or other rights to purchase Common Units or any such securities.¹

¹	With respect to Genesis Energy, LLC, the following sentence shall be inserted: For the avoidance of doubt, nothing herein shall restrict the Partnership or the General Partner of the Partnership from taking any action permitted by Section 5(o) of the Underwriting Agreement.

A-2

The undersigned hereby confirms that the undersigned has not, directly or indirectly, taken, and hereby covenants that the undersigned will not, directly or indirectly, take, any action designed, or which has constituted or will constitute or might reasonably be expected to cause or result in the stabilization or manipulation of the price of any security of the Partnership to facilitate the sale or resale of Common Units.

* * *

A-3

If (i) the Partnership or any Selling Unitholder notifies Barclays in writing that it does not intend to proceed with the Offering, (ii) the registration statement filed with the Commission with respect to the Offering is withdrawn or (iii) for any reason the Underwriting Agreement shall be terminated prior to the “time of purchase” (as defined in the Underwriting Agreement), this Lock-Up Agreement shall be terminated and the undersigned shall be released from the undersigned’s obligations hereunder.

Yours very truly,

The Units to be sold to the Underwriter pursuant to the Underwriting Agreement and 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 LP Act).

4.	The General Partner is (i) 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

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 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/October] , 2012 in the office of the Secretary of State of the State of Delaware or as of [September/October] , 2012 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

7.	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 and sale by the Selling Unitholders 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.

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 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 5(b), (c), (f), (g), (h) and (n) of the Underwriting Agreement.

11.

The Registration Statement was declared effective under the Act on April 25, 2011; 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.

12.	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 (10) of this letter, we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained or incorporated by reference in the Registration Statement, the Disclosure Package and the 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 Selling Unitholders, representatives of the independent public accountants for the Partnership, representatives of the Underwriter and representatives of the Underwriter’s 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) 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

B-1-4

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 such 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 8:30 A.M. (New York time) on October 2, 2012 (which you have informed us is a time prior to the time of the first sale of the Units by the Underwriter), contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they are made, not misleading or (iii) the Final Prospectus Supplement, as of its date and as of the Closing Date, contained or contains any untrue statement of a material fact or omitted or omits to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except that in the case of each of clauses (i)-(iii) above, we do not express any view as to the financial statements, the notes and schedules thereto and other financial and accounting information contained or incorporated by reference therein.

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 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.
