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 $ per unit, the respective number of Firm Units set forth opposite the names of the Underwriters in Schedule A hereto.

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 ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇ LLP, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇ (the “Closing Location”), at 10:00 A.M., New York time, on May [20], 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. A meeting will be held at the Closing Location at 3:00 p.m., New York City time, on the business day next preceding such First Closing Date, at which meeting the final drafts of the documents to be delivered pursuant to this Agreement will be available for review by the parties hereto.

In addition, upon written notice from the Representatives given to the Partnership from time to time not more than 30 days subsequent to the date of this Agreement, the Underwriters may purchase all or less than all of the Optional Units at a purchase price of $ per unit. 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.

Each time for the delivery of and payment for the Optional Units, being herein referred to as an “Optional Closing Date”, which may be the First Closing Date (the First Closing Date and each Optional Closing Date, if any, being sometimes referred to as a “Closing Date”), shall be determined by the Representatives but shall be not later than five full business days after written notice of election to purchase Optional Units is given. The Partnership will deliver the Optional Units being purchased on each Optional Closing Date to or as instructed by the Representatives through the facilities of DTC for the accounts of the several Underwriters in a form reasonably acceptable to the Representatives against payment of the purchase price therefor in Federal (same day) funds by wire transfer to an account at a bank designated by the Partnership, at the above office of

▇▇▇▇▇▇ & ▇▇▇▇▇▇▇ LLP. A meeting will be held at the Closing Location at 3:00 p.m., New York City time, on the business day next preceding such Optional Closing Date, at which meeting the final drafts of the documents to be delivered pursuant to this Agreement will be available for review by the parties hereto.

4. Offering by Underwriters. It is understood that the several Underwriters propose to offer the Offered Units for sale to the public as set forth in the Final Prospectus.

5. Certain Agreements of the Partnership. The Partnership agrees with the several Underwriters that:

(a) Additional Filings. The Partnership will effect all filings required under Rule 424(b), in the manner and within the time period required by Rule 424(b). The Partnership will advise the Representatives promptly of any such filing pursuant to Rule 424(b) and provide satisfactory evidence to the Representatives of such timely filing. 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.

(b) Filing of Amendments; Response to Commission Requests. The Partnership will promptly advise the Representatives of any proposal to amend or supplement at any time the Initial Registration Statement, any Additional Registration Statement or any Statutory Prospectus and will not effect such amendment or supplementation without the Representatives’ consent; and the Partnership will also advise the Representatives promptly of (i) the effectiveness of any Additional Registration Statement (if its Effective Time is subsequent to the execution and delivery of this Agreement), (ii) any amendment or supplementation of a Registration Statement or any Statutory Prospectus, (iii) any request by the Commission or its staff for any amendment to any Registration Statement, for any supplement to any Statutory Prospectus or for any additional information, (iv) the institution by the Commission of any stop order proceedings in respect of a Registration Statement or the threatening of any proceeding for that purpose, and (v) the receipt by the Partnership of any notification with respect to the suspension of the qualification of the Offered Units in any jurisdiction or the institution or threatening of any proceedings for such purpose. 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.

(c) Continued Compliance with Securities Laws. If, at any time when a prospectus relating to the Offered Units is (or but for the exemption in Rule 172 would be) required to be delivered under the Act by any Underwriter or dealer, any event occurs as a result of which the Final Prospectus as then amended or supplemented would contain an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to 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. Neither the Representatives’ consent to, nor the Underwriters’ delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 7 hereof.

(d) Rule 158. As soon as practicable, but not later than the Availability Date (as defined below), the Partnership will make generally available to its securityholders an earnings statement covering a period of at least 12 months beginning after the Effective Time of the Initial Registration Statement (or, if later, the

Effective Time of the Additional Registration Statement) which will satisfy the provisions of Section 11(a) of the Act and Rule 158 under the Act. For the purpose of the preceding sentence, “Availability Date” means the day after the end of the fourth fiscal quarter following the fiscal quarter that includes such Effective Time on which the Partnership is required to file its Form 10-Q for such fiscal quarter except that, if such fourth fiscal quarter is the last quarter of the Partnership’s fiscal year, “Availability Date” means the day after the end of such fourth fiscal quarter on which the Partnership is required to file its Form 10-K.

(e) Furnishing of Prospectuses. The Partnership will furnish to the Representatives copies of each Registration Statement (three of which will be signed and will include all exhibits), each related Statutory Prospectus, and, so long as a prospectus relating to the Offered Units is (or but for the exemption in Rule 172 would be) required to be delivered under the Act, the Final Prospectus and all amendments and supplements to such documents, in each case in such quantities as the Representatives request. 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. All other documents shall be so furnished as soon as available.

(f) Blue Sky Qualifications. The Partnership will take such actions as the Representatives may reasonably request for the qualification of the Offered Units for sale under the laws of such jurisdictions as the Representatives reasonably designate and will continue such qualifications in effect so long as required for the distribution; provided, however, that in connection therewith the Partnership shall not be required to qualify as a foreign partnership or to file a general consent to service of process or subject itself to taxation for doing business in any jurisdiction.

(g) Reporting Requirements. During the period of five years hereafter, the Partnership will furnish to the Representatives and, upon request, to each of the other Underwriters, as soon as practicable after the end of each fiscal year, a copy of its annual report to unitholders for such year; and the Partnership will furnish to the Representatives (i) as soon as available, a copy of each report and any definitive proxy statement of the Partnership filed with the Commission under the Exchange Act or mailed to stockholders, and (ii) from time to time, such other information concerning the Partnership as the Representatives may reasonably request. However, so long as the Partnership is subject to the reporting requirements of either Section 13 or Section 15(d) of the Exchange Act and is timely filing reports with the Commission on its Electronic Data Gathering, Analysis and Retrieval system (“▇▇▇▇▇”), it is not required to furnish such reports or statements to the Underwriters.

(h) Payment of Expenses. The Partnership will pay all expenses incident to the performance of its obligations under this Agreement, including but not limited to any filing fees and other expenses (including the reasonable fees and disbursements of counsel to the Underwriters) incurred in connection with qualification of the Offered Units for sale under the laws of such jurisdictions as the Representatives designate and the preparation and printing of memoranda relating thereto, costs and expenses related to the review by FINRA of the Offered Units (including filing fees and the reasonable fees and expenses of counsel for the Underwriters relating to such review), costs and expenses relating to investor presentations or any “road show” in connection with the offering and sale of the Offered Units including (provided that the costs associated with the chartering of an aircraft used by the Partnership and the Underwriters to attend meetings with prospective purchasers of the Common Units will be divided equally between the Partnership on the one hand and the Underwriters on the other hand, and each of the Partnership and the Underwriters will pay for their own costs in connection with meetings with prospective purchasers), fees and expenses incident to listing the Offered Units on the New York Stock Exchange, fees and expenses in connection with the registration of the Offered Units under the Exchange Act, and expenses incurred in distributing preliminary prospectuses and the Final Prospectus (including any amendments and supplements thereto) to the Underwriters and for expenses incurred for preparing, printing and distributing any Issuer Free Writing Prospectuses to investors or prospective investors. It is understood, however, that except as set forth in this Section 5(h), the Underwriters will pay all of their own costs and expenses, including the fees of their counsel.

(i) Use of Proceeds. The Partnership will use the net proceeds received in connection with this offering in the manner described in the “Use of Proceeds” section of the General Disclosure Package.

(j) Absence of Manipulation. The Partnership will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, stabilization or manipulation of the price of any securities of the Partnership to facilitate the sale or resale of the Offered Units.

(k) Restriction on Sale of Common Units. For the period specified below (the “Lock-Up Period”), the Partnership will not, directly or indirectly, take any of the following actions with respect to its Common Units or any securities convertible into or exchangeable or exercisable for any of its Common Units (“Lock-Up Securities”): (i) offer, sell, issue, contract to sell, pledge or otherwise dispose of Lock-Up Securities, (ii) offer, sell, issue, contract to sell, contract to purchase or grant any option, right or warrant to purchase Lock-Up Securities, (iii) enter into any swap, hedge or any other agreement that transfers, in whole or in part, the economic consequences of ownership of Lock-Up Securities, (iv) establish or increase a put equivalent position or liquidate or decrease a call equivalent position in Lock-Up Securities within the meaning of Section 16 of the Exchange Act or (v) file with the Commission a registration statement under the Act relating to Lock-Up Securities, or publicly disclose the intention to take any such action, without the prior written consent of Credit Suisse Securities (USA) LLC (“Credit Suisse”). The foregoing sentence shall not apply to (A) the Offered Units to be sold hereunder; (B) any Common Units issued or options to purchase Common Units granted pursuant to employee benefit or equity compensation plans of the Partnership referred to in the Registration Statement, the General Disclosure Package and the Final Prospectus and any registration statement on Form S-8 related thereto, provided that such Common Units issued or options granted pursuant to employee benefit or equity compensation plans of the Partnership will not vest or otherwise be transferable or exercisable during the remainder of the Lock-Up Period; or (C) securities equal to up to 10% of the Partnership’s outstanding Common Units issued by the Partnership in connection with the acquisition by the Partnership or any of its subsidiaries of the securities, business, property or other assets of another person or entity or pursuant to any plan assumed by the Partnership in connection with such acquisition. The initial Lock-Up Period will commence on the date hereof and continue for 60 days after the date hereof or such earlier date that Credit Suisse consents to in writing; provided, however, that if (1) during the last 17 days of the initial Lock-Up Period, the Partnership releases earnings results or material news or a material event relating to the Partnership occurs 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 occurrence of the materials news or material event, as applicable, unless Credit Suisse waives, in writing, such extension. The Partnership will provide Credit Suisse with notice of any announcement described in clause (2) of the preceding sentence that gives rise to an extension of the Lock-Up Period.

6. Free Writing Prospectuses. (a) Issuer Free Writing Prospectuses. The Partnership represents and agrees that, unless it obtains the prior consent of Credit Suisse, and each Underwriter represents and agrees that, unless it obtains the prior consent of the Partnership and Credit Suisse, it has not made and will not make any offer relating to the Offered Units that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Partnership and Credit Suisse is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Partnership and Credit Suisse agree that any such Permitted Free Writing Prospectus is listed on Schedule B hereto. The Partnership represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and record keeping. The Partnership represents that is has satisfied and agrees that it will satisfy the conditions in Rule 433 to avoid a requirement to file with the Commission any electronic road show.

The obligations of the several Underwriters to purchase and pay for the Firm Units on the First Closing Date and the Optional Units to be purchased on each Optional Closing Date will be subject to the accuracy of the representations and warranties of the Partnership Parties and Coffeyville Resources herein (as though made on such Closing Date), to the accuracy of the statements of Partnership officers made pursuant to the provisions hereof, to the performance by the Partnership Parties and of Coffeyville Resources of their obligations hereunder and to the following additional conditions precedent:

of this provision with respect to any of the above as such expenses are incurred; provided, however, that the Partnership will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Partnership by any Underwriter through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (b) below.

(b) Indemnification of the Partnership Parties. Each Underwriter will severally and not jointly indemnify and hold harmless each of the Partnership Parties, 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 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.

(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 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, 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, 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 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 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 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, 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 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.

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., ▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, Attention: ▇▇▇▇▇▇ ▇. ▇▇▇▇▇; 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 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 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 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 following discussions and arms-length negotiations with the

Representatives and the Partnership Parties 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 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 and that the Representatives have no obligation to disclose such interests and transactions to the Partnership Parties by virtue of any fiduciary, advisory or agency relationship; and

(d) Waiver. The Partnership Parties 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 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, including stockholders, unitholders, employees or creditors of the Partnership Parties.

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.

FORM OF CHIEF FINANCIAL OFFICER’S CERTIFICATE

CVR REFINING, LP

In connection with the offering, sale and issuance by CVR Refining, LP, a Delaware limited partnership (the “Partnership”), of common units representing limited partner interests (the “Units”) pursuant to a registration statement on Form S-1 under the Securities Act of 1933, as amended, filed with the Securities and Exchange Commission on March 29, 2013 (File No. 333-187631), as amended (the “Registration Statement”), the prospectus dated May , 2013 (the “Prospectus”), and an Underwriting Agreement, dated May [14], 2013 (the “Underwriting Agreement”), by and among the Partnership, CVR Refining GP, LLC, a Delaware limited liability company and CVR Refining Holdings, LLC, a Delaware limited liability company, and the Representatives (as defined herein), I, ▇▇▇▇▇ ▇. ▇▇▇▇, solely in my capacity as Chief Financial Officer of the Partnership and not in my individual capacity, have been asked to deliver this certificate to Credit Suisse Securities (USA) LLC, as representative of the several Underwriters named in the Underwriting Agreement (the “Representative”), on behalf of the Partnership. Based on my examination of the Partnership’s financial records and schedules undertaken by myself or members of my staff who are responsible for the Partnership’s financial accounting matters, I hereby certify, on behalf of the Partnership and solely in my capacity as Chief Financial Officer of the Partnership and not in my individual capacity, that:

I or members of my staff who are responsible for the Partnership’s financial and accounting matters supervised the compilation of the Partnership’s financial information specified in Annex I hereto (the “Specified Historical Operating Results”).

I or members of my staff who are responsible for the Partnership’s financial and accounting matters compared the amounts with respect to the Specified Historical Operating Results to the accounting records, analyses, financial schedules and other documents (collectively, the “Books and Records”) of the Partnership and found the amounts to be consistent and in agreement with the Books and Records and based on assumptions believed by the undersigned to be reasonable.

With respect to the Specified Historical Operating Results, nothing has come to my attention that causes me to believe that the financial information contained therein is not true, correct and accurate in all material respects.

This certificate is to assist the Representative in conducting and documenting its investigation of the affairs of the Partnership in connection with the offering of the Units covered by the Prospectus, and the Representative is entitled to rely on this certificate.
