3. Purchase, Sale and Delivery of Offered Units . On the basis of the representations, warranties and agreements and subject to the terms and conditions set forth herein, the Partnership agrees to sell to the several Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Partnership, at a purchase price of $23.625 per unit, the respective number of Firm Units set forth opposite the names of the Underwriters in Schedule A hereto; provided, that any Firm Units sold by the Underwriters to Icahn Enterprises, L.P. (the “ Icahn Units ”) shall be sold at a purchase price of $25.00 per unit, and such Icahn Units shall be allocated among the Underwriters by multiplying the number of Icahn Units by a fraction, the numerator of which is the number of Firm Units set forth opposite the name of such Underwriter in Schedule A hereto and the denominator of which is the total number of Firm Units (subject to adjustment by the Representatives to eliminate fractions).

The Partnership will deliver the Firm Units to or as instructed by the Representatives through the facilities of the Depository Trust Company (“ DTC ”) for the accounts of the several Underwriters in a form reasonably acceptable to the Representatives against payment of the purchase price by the Underwriters in Federal (same day) funds by wire transfer to an account designated by the Partnership at the office of Latham & Watkins LLP, 811 Main Street, Suite 3700, Houston, Texas 77002 (the “ Closing Location ”), at 10:00 A.M., New York time, on January 23, 2013, or at such other time not later than seven full business days thereafter as the Representatives and the Partnership agree in writing, such time being herein referred to as the “ First Closing Date .” For purposes of Rule 15c6-1 under the Exchange Act, the First Closing Date (if later than the otherwise applicable settlement date) shall be the settlement date for payment of funds and delivery of securities for all the Offered Units sold pursuant to the offering.

The Partnership agrees to sell to the Underwriters the number of Optional Units specified in such notice and the Underwriters agree, severally and not jointly, to purchase such Optional Units. Such Optional Units shall be purchased for the account of each Underwriter in the same proportion as the number of Firm Units set forth opposite such Underwriter’s name in Schedule A hereto bears to the total number of Firm Units (subject to adjustment by the Representatives to eliminate fractions) and may be purchased by the Underwriters only for the purpose of covering over-allotments made in connection with the sale of the Firm Units. No Optional Units shall be sold or delivered unless the Firm Units previously have been, or simultaneously are, sold and delivered. The right to purchase the Optional Units or any portion thereof may be exercised from time to time and to the extent not previously exercised may be surrendered and terminated at any time upon notice by the Representatives to the Partnership.

If an Additional Registration Statement is necessary to register a portion of the Offered Units under the Act but the Effective Time thereof has not occurred as of the execution and delivery of this Agreement, the Partnership will file the additional registration statement or, if filed, will file a post-effective amendment thereto with the Commission pursuant to and in accordance with Rule 462(b) on or prior to 10:00 P.M., New York time, on the date of this Agreement or, if earlier, on or prior to the time the Final Prospectus is finalized and distributed to any Underwriter, or will make such filing at such later date as shall have been consented to by the Representatives.

The Partnership will use its reasonable best efforts to prevent the issuance of any such stop order or the suspension of any such qualification and, if issued, to obtain as soon as possible the withdrawal thereof.

14

amend the Registration Statement or supplement the Final Prospectus to comply with the Act, the Partnership will promptly notify the Representatives of such event and will promptly prepare and file with the Commission and furnish, at its own expense, to the Underwriters and the dealers and any other dealers upon request of the Representatives, an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance.

The Partnership will use its commercially reasonable efforts to ensure that the Final Prospectus is so furnished at or prior to 5:00 P.M., New York time, on the business day following the execution and delivery of this Agreement.

Each Underwriter will severally and not jointly indemnify and hold harmless each of the Partnership Parties and Coffeyville Resources, and their respective directors, officers, employees, and each person, if any, who controls such party within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, an “ Underwriter Indemnified Party ”), against any losses, claims, damages or liabilities to which such Underwriter Indemnified Party may become subject, under the Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of any Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or the alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Partnership by such Underwriter through the Representatives specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by such Underwriter Indemnified Party in connection with investigating or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Underwriter Indemnified Party is a party thereto), whether threatened or commenced, based upon any such untrue statement or omission, or any such alleged untrue statement or omission as such expenses are incurred, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Final Prospectus furnished on behalf of each Underwriter under the heading “Underwriting”: the list of Underwriters and their respective participation in the sale of Common Units, paragraph 4 (relating to the selling concession and reallowances), the third sentence of the seventh paragraph (relating to sales to accounts of which underwriters have discretionary authority) and paragraph 11 (relating to stabilizing transactions, over-allotment transactions, syndicate covering transactions and penalty bids).

(c) Actions against Parties; Notification . Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and

20

provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. In connection with such action, the indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to local counsel) in any one action or separate but substantially similar actions in the same jurisdiction arising out of the same general allegations or circumstances, designated by the Representatives in the case of paragraph (a) of this Section 8 or the Partnership in the case of paragraph (b) of this Section 8, representing the indemnified parties under such paragraph (a) or paragraph (b), as the case may be, who are parties to such action or actions. Notwithstanding the indemnifying party’s election to appoint counsel (including local counsel) to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party.

Notwithstanding anything contained herein to the contrary, if indemnity may be sought pursuant to the second paragraph in Section 8(a) hereof in respect of such action or proceeding, then in addition to such separate firm for the indemnified parties, the indemnifying party shall be liable for the reasonable fees and expenses of not more than one separate firm (in addition to any local counsel) for UBS-FinSvc for the defense of any losses, claims, damages and liabilities arising out of the Directed Unit Program, and all persons, if any, who control UBS-FinSvc within the meaning of either Section 15 of the Act of Section 20 of the Exchange Act. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action 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 (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(d) Contribution . If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Partnership Parties and Coffeyville Resources on the one hand and the Underwriters on the other from the offering of the Securities 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 Parties and Coffeyville Resources, on the one hand, and the Underwriters, on the other, in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Partnership Parties and Coffeyville Resources, on the one hand, and the Underwriters, on the other, shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the

21

Partnership Parties bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Partnership Parties or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the underwriting discount or commission applicable to the Offered Units purchased by such Underwriter hereunder. 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’ obligations in this Section 8(d) to contribute are several in proportion to their respective underwriting obligations and not joint. The Partnership Parties and Coffeyville Resources and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8(d) 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 which does not take account of the equitable considerations referred to in this Section 8(d).

9. Default of Underwriters . If any Underwriter or Underwriters default in their obligations to purchase Offered Units hereunder on either the First or any Optional Closing Date and the aggregate number of Offered Units that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total number of Offered Units that the Underwriters are obligated to purchase on such Closing Date, Credit Suisse may make arrangements satisfactory to the Partnership for the purchase of such Offered Units by other persons, including any of the Underwriters, but if no such arrangements are made by such Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Units that such defaulting Underwriters agreed but failed to purchase on such Closing Date. If any Underwriter or Underwriters so default and the aggregate number of Offered Units with respect to which such default or defaults occur exceeds 10% of the total number of Offered Units that the Underwriters are obligated to purchase on such Closing Date and arrangements satisfactory to Credit Suisse and the Partnership for the purchase of such Offered Units by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Partnership, except as provided in Section 10 (provided that if such default occurs with respect to Optional Units after the First Closing Date, this Agreement will not terminate as to the Firm Units or any Optional Units purchased prior to such termination). As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

10. Survival of Certain Representations and Obligations . The respective indemnities, agreements, representations, warranties and other statements of the Partnership Parties and Coffeyville Resources or their respective officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Partnership Parties, Coffeyville Resources or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Units. If the purchase of the Offered Units by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 7(c)(iii)-(viii) and 9 hereof, the Partnership Parties will reimburse the Underwriters for all reasonable and documented out-of-pocket expenses (including reasonable and documented fees and disbursements of outside counsel) reasonably incurred by them in connection with the offering of the Offered Units, and the respective obligations of the Partnership Parties and Coffeyville Resources and the Underwriters pursuant to Section 8 hereof shall remain in effect. In addition, if any Offered Units have been purchased hereunder, the representations and warranties in Section 2 and all obligations under Section 5 shall also remain in effect.

22

11. Notices . All communications hereunder will be in writing and, if sent to the Underwriters, will be mailed, delivered or telegraphed and confirmed to the Representatives, c/o Credit Suisse Securities (USA) LLC, Eleven Madison Avenue, New York, N.Y. 10010-3629, Attention: LCD-IBD, or, if sent to the Partnership, will be mailed, delivered or telegraphed and confirmed to it at c/o CVR Energy, Inc., 2277 Plaza Drive, Suite 500, Sugar Land, Texas 77479, Attention: Edmund S. Gross; provided, however, that any notice to an Underwriter pursuant to Section 8 will be mailed, delivered or telegraphed and confirmed to such Underwriter.

12. Successors . This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and controlling persons referred to in Section 8, and no other person will have any right or obligation hereunder.

13. Representation of Underwriters . The Representatives will act for the several Underwriters in connection with this financing, and any action under this Agreement taken by the Representatives jointly will be binding upon all the Underwriters.

14. Counterparts . This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

15. Absence of Fiduciary Relationship. The Partnership Parties and Coffeyville Resources acknowledge and agree that:

(a) No Other Relationship . The Representatives have been retained solely to act as underwriters in connection with the sale of the Offered Units and that no fiduciary, advisory or agency relationship between the Partnership Parties or Coffeyville Resources and the Representatives has been created in respect of any of the transactions contemplated by this Agreement or the Final Prospectus, irrespective of whether the Representatives have advised or are advising the Partnership Parties or Coffeyville Resources on other matters;

(b) Arms-Length Negotiations . The purchase price of the Offered Units set forth in this Agreement was established by the Partnership Parties and Coffeyville Resources following discussions and arms-length negotiations with the Representatives and the Partnership Parties and Coffeyville Resources are capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated by this Agreement;

(c) Absence of Obligation to Disclose . The Partnership Parties and Coffeyville Resources have been advised that the Representatives and their affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Partnership Parties or Coffeyville Resources and that the Representatives have no obligation to disclose such interests and transactions to the Partnership Parties or Coffeyville Resources by virtue of any fiduciary, advisory or agency relationship; and

(d) Waiver . The Partnership Parties and Coffeyville Resources waive, to the fullest extent permitted by law, any claims they may have against the Representatives for breach of fiduciary duty or alleged breach of fiduciary duty and agree that the Representatives shall have no liability (whether direct or indirect) to the Partnership Parties or Coffeyville Resources in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Partnership Parties or Coffeyville Resources, including stockholders, unitholders, employees or creditors of the Partnership Parties or Coffeyville Resources.

23

16. Applicable Law . This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

The Partnership Parties and Coffeyville Resources hereby submit to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. The Partnership Parties and Coffeyville Resources irrevocably and unconditionally waive any objection to the laying of venue of any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby in Federal and state courts in the Borough of Manhattan in The City of New York and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit or proceeding in any such court has been brought in an inconvenient forum.

As an inducement to the underwriters to execute the Underwriting Agreement (the “ Underwriting Agreement ”), among CVR Refining, LP (the “ Partnership ”), CVR Refining GP, LLC, CVR Refining Holdings, LLC, Coffeyville Resources, LLC and the underwriters named therein (the “ Underwriters ”), pursuant to which an offering will be made that is intended to result in the establishment of a public market for common units representing limited partner interests in the Partnership (the “ Securities ”), the undersigned hereby agrees that during the period specified in the following paragraph (the “ Lock-Up Period ”), the undersigned will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any Securities (including any Securities acquired after the date hereof) or securities convertible into or exchangeable or exercisable for any Securities, enter into a transaction which would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of the Securities, whether any such aforementioned transaction is to be settled by delivery of the Securities or such other securities, in cash or otherwise, or publicly disclose the intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap, hedge or other arrangement, without, in each case, the prior written consent of Credit Suisse Securities (USA) LLC (“ Credit Suisse ”). In addition, the undersigned agrees that, without the prior written consent of Credit Suisse, it will not, during the Lock-Up Period, make any demand for or exercise any right with respect to, the registration of any Securities or any security convertible into or exercisable or exchangeable for the Securities that would require the Partnership to file a registration statement during the Lock-Up Period.

The initial Lock-Up Period will commence on the date of this Lock-Up Agreement and continue and include the date 180 days after the public offering date set forth on the final prospectus used to sell the Securities (the “ Public Offering Date ”) pursuant to the Underwriting Agreement; provided, however, that if (1) during the last 17 days of the initial Lock-Up Period, the Partnership releases earnings results or announces material news or a material event or (2) prior to the expiration of the initial Lock-Up Period, the Partnership announces that it will release earnings results during the 16-day period beginning on the last day of the initial Lock-Up Period, then in each case the Lock-Up Period will be extended until the expiration of the 18-day period beginning on the date of release of the earnings results or the announcement of the material news or material event, as applicable, unless Credit Suisse waives, in writing, such extension.

The undersigned agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this Lock-Up Agreement during the period from the date of this Lock-Up Agreement to and including the 34 ^th day following the expiration of the initial Lock-Up Period, it will give notice thereof to the Partnership and will not consummate such transaction or take any such action unless it has received written confirmation from the Partnership that the Lock-Up Period (as may have been extended pursuant to the previous paragraph) has expired.

Notwithstanding the foregoing, (1) the undersigned may transfer Securities (i) as a bona fide gift or gifts, provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth herein, (ii) as a distribution to members, limited partners or stockholders of the undersigned, provided that the members, limited partners or stockholders, as the case may be, agree to be bound in writing by the restrictions set forth herein, (iii) to the undersigned’s affiliates or to any investment fund or other entity controlled or managed by the undersigned, provided that the affiliates or investment funds or other entities controlled or managed by the undersigned, as the case may be, agree to be bound in writing by the restrictions set forth herein, or (iv) to members of his or her immediate family, or to any trust for the direct or indirect benefit of the undersigned or one or more members of the immediate family of the undersigned, provided that such immediate family members (or trustee in the case of a trust) agree to be bound in writing by the restrictions set forth herein, and provided further that any such transfer pursuant to sub-clauses (i), (ii), (iii) or (iv) above shall not involve a disposition for value; (2) the undersigned may sell Securities purchased in the open market following the initial public offering described herein; or (3) the undersigned may transfer Securities with the prior written consent of Credit Suisse; provided, however, that it shall be a condition to transfers made pursuant to clauses (i), (ii), (iii) and (iv) of the foregoing clause (1) that no public reports, including but not limited to reports pursuant to Rule 144 of the Securities Act of 1933, as amended, or pursuant to Section 16 of the Securities Exchange Act of 1934, as amended, are required to be filed by the undersigned during the Lock-Up Period (as such may have been extended pursuant to the terms of this Lock-Up Agreement) and no such reports are voluntarily filed by the undersigned during the Lock-Up Period (as such may have been extended pursuant to the terms of this Lock-Up Agreement) in connection with such transfer or distribution (other than (i) a filing under Section 16(a) of the Securities Exchange Act of 1934 which reports solely one or more acquisitions of the Partnership’s securities or (ii) a filing on Form 5 made after the expiration of the restricted period described in the foregoing paragraphs). For purposes of this Lock-Up Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin. In addition, notwithstanding the foregoing, if the undersigned is a corporation, the corporation may transfer Securities to any wholly-owned subsidiary of such corporation; provided, however, that in any such case, it shall be a condition to the transfer that the transferee execute an agreement stating that the transferee is receiving and holding such Securities subject to the provisions of this Lock-Up Agreement and there shall be no further transfer of such Securities except in accordance with this Lock-Up Agreement, and provided further that any such transfer shall not involve a disposition for value.

In furtherance of the foregoing, the Partnership and its transfer agent and registrar are hereby authorized to decline to make any transfer of shares of Securities if such transfer would constitute a violation or breach of this Lock-Up Agreement.

If the undersigned is an officer or director of the general partner of the Partnership, the undersigned further agrees that the foregoing restrictions in this Lock-Up Agreement shall be equally applicable to any issuer-directed Securities the undersigned may purchase in the above-referenced offering.

This Lock-Up Agreement shall be binding on the undersigned and the successors, heirs, personal representatives and assigns of the undersigned. This Lock-Up Agreement shall lapse and become null and void if the Public Offering Date shall not have occurred on or before March 31, 2013.

(r) The opinion of Vinson & Elkins L.L.P. that is filed as Exhibit 8.1 to the Registration Statement is confirmed, and the Underwriters may rely on such opinion as if it were addressed to them.

(s) The Partnership is not, and after giving effect to the offering and sale of the Offered Units and the application of the proceeds thereof as described in the General Disclosure Package and the Final Prospectus will not be, an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

(t) To our knowledge, and based solely on a review of such counsel’s litigation docket, there are no (i) legal or governmental proceedings pending to which any of the Partnership Entities is a party or of which any property of the Partnership Entities is the subject that are required to be described in the Registration Statement or the Final Prospectus, but are not so described, or (ii) agreements, contracts, indentures, leases or other instruments that are required to be described in the Registration Statement or the Final Prospectus or to be filed as an exhibit to the Registration Statement that are not described or filed as required by the Act.

In addition, such counsel shall state that they have reviewed the Registration Statement, the General Disclosure Package and the Final Prospectus and have participated in conferences with officers and other representatives of the General Partner, the Partnership and the Sponsor and the independent registered public accounting firm of the Partnership and representatives of the Underwriters, at which the contents of the Registration Statement, the General Disclosure Package and the Final Prospectus and related matters were discussed, and although such counsel has not independently verified, is not passing upon, and is not assuming any responsibility for the accuracy, completeness or fairness of the statements contained in, the Registration Statement, the General Disclosure Package and the Final Prospectus (except to the extent specified in paragraphs (k), (l) and (m) above), based on the foregoing, no facts have come to such counsel’s attention that lead such counsel to believe that:

(a) the Registration Statement, at the time it became effective on January 16, 2013, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading;

(b) the General Disclosure Package, as of the Applicable Time, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; or

(c) the Final Prospectus, as of its date or as of such Closing Date, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading,

except that in each case such counsel need express no opinion with respect to the financial statements and notes and related schedules and other financial or accounting data contained in or omitted from the General Disclosure Package and the Final Prospectus.

In rendering such opinion, such counsel may (i) rely in respect of matters of fact upon certificates of officers and other employees of the General Partner, the Partnership and the Sponsor and upon information obtained from public officials, (ii) assume that all documents submitted to them as originals are authentic, that all copies submitted to such counsel conform to the originals thereof, and that the signatures on all documents examined by such counsel are genuine, (iii) state that such counsel’s opinion is limited to federal laws, the laws of the State of New York, the Delaware LP Act and the Delaware LLC Act and (iv) with respect to the opinions expressed as to the due qualification or registration as a foreign limited partnership or limited liability, as the case may be, of the Partnership Entities, state that such opinions are based upon certificates of foreign qualification or registration provided by the Secretary of State of the states listed on an annex to be attached to such counsel’s opinion.
