(ii) The limited liability company agreement of Coffeyville Resources (the “Coffeyville Resources LLC Agreement”) has been duly authorized, executed and delivered by the parties party thereto and is a valid and legally binding agreement of the parties party thereto, enforceable against the parties party thereto in accordance with its terms; provided that the enforceability thereof may be limited by bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law); and provided further, that the indemnity, contribution and exoneration provisions contained therein may be limited by applicable laws and public policy;

(iii) Coffeyville Resources has all requisite limited liability company power and authority to sell, assign, transfer and deliver the LP Units to be sold by it, in accordance with and upon the terms and conditions set forth in this Agreement, the Partnership Agreement, the Coffeyville Resources LLC Agreement, the Registration Statement, the Pricing Prospectus and the Prospectus;

(iv) Coffeyville Resources owns the LP Units to be sold by Coffeyville Resources hereunder, free and clear of all Liens. Upon payment for the LP Units to be sold by Coffeyville Resources pursuant to this Agreement, delivery of such LP Units, as directed by the Underwriters, to Cede & Co. or such other nominee as may be designated by The Depository Trust Company (“DTC”) on the Company’s unit registry, registration of such LP Units in the name of Cede & Co. or such other nominee and the crediting of such LP Units on the books of DTC to securities accounts (within the meaning of Section 8-501(a) of the UCC) of the Underwriters (assuming that neither DTC nor any such Underwriter has notice of any adverse claim within the meaning of Section 8-105 of the Uniform Commercial Code, as in effect in the State of New York on the date hereof

(“UCC”), to such LP Units), then, assuming appropriate entries to the accounts of the several Underwriters on the records of DTC have been made pursuant to the UCC, (A) under Section 8-501 of the UCC, the Underwriters will acquire a security entitlement (within the meaning of Part 5 of Article 8 of the UCC) in respect of such LP Units, and (B) no action based on any “adverse claim” (within the meaning of Section 8-102(a)(1) of the UCC) to such LP Units may be asserted against the Underwriters with respect to such security entitlement.

(v) The sale of the LP Units as herein contemplated and the compliance by Coffeyville Resources with this Agreement, and the consummation of the transactions herein contemplated, including the sale, assignment, transfer and delivery of the LP Units by Coffeyville Resources, will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which Coffeyville Resources is a party or by which Coffeyville Resources is bound or to which any of the property or assets of Coffeyville Resources is subject; nor will such action result in any violation of the provisions of the Coffeyville Resources LLC Agreement or any statute or any order, rule or regulation of any court or governmental agency or body having jurisdiction over Coffeyville Resources or any of its properties, after giving effect to any consents, approvals, authorizations, orders, registrations, qualifications, waivers and amendments as have been obtained or made as of the date of this Agreement; nor does or will such action result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of Coffeyville Resources; and no consent, approval, authorization, order, registration or qualification of or with any such court or governmental agency or body is required for the sale and delivery of the LP Units or the consummation by Coffeyville Resources of the transactions contemplated by this Agreement, except (i) the registration under the Exchange Act and the Act of LP Units, and the listing of the LP Units on the Exchange, all of which have occurred, (ii) such consents, approvals, authorizations, registrations or qualifications as may be required under state securities or Blue Sky laws or the rules and regulations of FINRA in connection with the purchase and distribution of the LP Units by the Underwriters; and (iii) where the failure to obtain or make any such consent, approval, authorization, order, registration, or qualification would not reasonably be expected, individually and in the aggregate, to have a Material Adverse Effect or would not materially impair the consummation of the transactions herein contemplated;

(vi) Assuming no purchase by the Underwriters of any Optional LP Units, at the First Time of Delivery after giving effect to the sale of the Firm LP Units, Coffeyville Resources will own 38,920,000 Common Units;

(vii) Coffeyville Resources owns all of the issued and outstanding member interests in Managing GP free and clear of all Liens; and

(viii) In order to document the Underwriters’ compliance with the reporting and withholding provisions of the Tax Equity and Fiscal Responsibility Act of 1982 with respect to the transactions contemplated herein, Coffeyville Resources will deliver to Credit Suisse Securities (USA) LLC (“Credit Suisse”) on behalf of the Underwriters prior to the Time of Delivery a properly completed and executed United States Treasury Department Form W-9 (or other applicable form or statement specified by Treasury Department regulations in lieu thereof).

2. Subject to the terms and conditions herein set forth, (a) Coffeyville Resources agrees to sell to each of the Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from Coffeyville Resources, at a purchase price per Common Unit of $24.38 (which is equal to the public offering price of $25.15 per Common Unit less underwriting discounts and commissions of $0.77 per Common Unit), the number of Firm LP Units set forth opposite the name of such Underwriter in Schedule I hereto and (b) in the event and to the extent that the Underwriters shall exercise the election to purchase Optional LP Units as provided below, Coffeyville Resources agrees to sell to each of the Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from Coffeyville Resources, at the purchase price per Common Unit set forth in clause (a) of this Section 2, that portion of the number of Optional LP Units as to which such election shall have been exercised (to be adjusted by you so as to eliminate fractional units) determined by multiplying such number of Optional LP Units by a fraction, the numerator of which is the maximum number of Optional LP Units which such Underwriter is entitled to purchase as set forth opposite the name of such Underwriter in Schedule I hereto and the denominator of which is the maximum number of Optional LP Units that all of the Underwriters are entitled to purchase hereunder.

Coffeyville Resources hereby grants to the Underwriters, severally and not jointly, the right to purchase at their election up to 1,800,000 Optional LP Units, at the purchase price per Common Unit set forth in the paragraph above, for the sole purpose of covering sales of LP Units in excess of the number of Firm LP Units. Credit Suisse may elect to exercise this right on behalf of the Underwriters in whole or from time to time in part. Any such election to purchase Optional LP Units may be exercised only by written notice from Credit Suisse to Coffeyville Resources, given within a period of 30 calendar days after the date of this Agreement, setting forth the aggregate number of Optional LP Units to be purchased and the date on which such Optional LP Units are to be delivered, as determined by Credit Suisse but in no event earlier than the First Time of Delivery or, unless Credit Suisse and Coffeyville Resources otherwise agree in writing, earlier than two or later than ten business days after the date of such notice.

3. Upon the authorization by Coffeyville Resources of the release of the Firm LP Units, the several Underwriters propose to offer the Firm LP Units for sale upon the terms and conditions set forth in the Prospectus.

4. (a) The LP Units to be purchased by each Underwriter hereunder, in definitive form, and in such authorized denominations and registered in such names as Credit Suisse may request upon at least forty-eight hours’ prior notice to Coffeyville Resources shall be delivered by or on behalf of Coffeyville Resources to Credit Suisse, through the facilities of DTC, for the account of such Underwriter, against payment by or on behalf of such Underwriter of the purchase price therefor by wire transfer of Federal (same-day) funds to the account specified by Coffeyville Resources to Credit Suisse at least forty-eight hours in advance. The time and date of such delivery and payment shall be, with respect to the Firm LP Units, 9:30 a.m., New York City time, on May 28, 2013 or such other time and date as Credit Suisse and Coffeyville Resources may agree upon in writing, and, with respect to the Optional LP Units, 9:30 a.m., New York time, on the date specified by Credit Suisse in the written notice given by Credit Suisse of the Underwriters’ election to purchase such Optional LP Units, or such other time and date as Credit Suisse and Coffeyville Resources may agree upon in writing. Such time and date for delivery of the Firm LP Units is herein called the “First Time of Delivery”, such time and date for delivery of any Optional LP Units, if not the First Time of Delivery, is herein called an “Option Time of Delivery”, and each such time and date for delivery is herein called a “Time of Delivery”.

(b) The documents to be delivered at each Time of Delivery by or on behalf of the parties hereto pursuant to Section 8 hereof, including the cross receipt for the LP Units and any additional documents reasonably requested by the Underwriters, will be delivered at the offices of Debevoise & Xxxxxxxx LLP, 000 Xxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000 (the “Closing Location”), and the LP Units will be delivered electronically via the facilities of DTC, all at such Time of Delivery. A meeting will be held at the Closing Location at 2:00 p.m., New York City time, on the New York Business Day next preceding such Time of Delivery, at which meeting the final drafts of the documents to be delivered pursuant to the preceding sentence will be available for review by the parties hereto. For the purposes of this Section 4, “New York Business Day” shall mean each Monday, Tuesday, Wednesday, Thursday and Friday that is not a day on which banking institutions in New York City are generally authorized or obligated by law or executive order to close.

5. The Company agrees with each of the several Underwriters:

(a) To prepare the Prospectus in a form to which you shall not have reasonably objected on a timely basis and to file such Prospectus pursuant to Rule 424(b) under the Act not later than the Commission’s close of business on the second business day following the execution and delivery of this Agreement; to make no further amendment or any supplement to the Registration Statement or the Prospectus prior to the last Time of Delivery which shall be reasonably disapproved by you promptly after reasonable notice thereof; to advise you, promptly after it receives notice thereof, of the time when any amendment to the Registration Statement has been filed or becomes effective or any amendment or supplement to the Prospectus has been filed and to furnish you with copies thereof; to file promptly all material required to be filed by the Company with the Commission pursuant to Rule 433(d) under the Act; to advise you, promptly after it receives notice thereof, of the issuance by the Commission of any stop order or of any order preventing or suspending the use of any Preliminary Prospectus Supplement, the Pricing Prospectus or other prospectus in respect of the LP Units, of the suspension of the qualification of the LP Units for offering or sale in any jurisdiction, of the initiation or threatening of any proceeding for any such purpose, or of any request by the Commission for the amending or supplementing of the Registration Statement or the Prospectus or for additional information; and, in the event of the issuance of any stop order or of any order preventing or suspending the use of any Preliminary Prospectus Supplement, the Pricing Prospectus or other prospectus or suspending any such qualification, to promptly use its reasonable best efforts to obtain the withdrawal of such order;

(b) Promptly from time to time to take such action as you may reasonably request to qualify the LP Units for offering and sale under the securities laws of such jurisdictions as you may request and to comply with such laws so as to permit the continuance of sales and dealings therein in such jurisdictions for as long as may be necessary to complete the distribution of the LP Units, provided that in connection therewith the Company 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;

(c) To furnish the Underwriters prior to 5:00 p.m., New York City time, on the New York Business Day next succeeding the date of this Agreement and from time to time, with written and electronic copies of the Prospectus in New York City in such quantities as you may reasonably request, and, if (i) the Underwriters notify the Company that or (ii) the Company otherwise has knowledge that the delivery of a prospectus (or in lieu thereof, the notice referred to in Rule 173(a) under the Act) is required at any time prior to the expiration of nine months after the time of issue of the Prospectus in connection with the offering or sale of the LP Units and if at such time any event shall have occurred as a result of which the Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made when such Prospectus (or in lieu thereof, the notice referred to in Rule 173(a) under the Act) is delivered, not misleading, or, if for any other reason it shall be necessary during such same

period to amend or supplement the Prospectus in order to comply with the Act, to notify you and upon your request to prepare and furnish without charge to each Underwriter and to any dealer in securities as many written and electronic copies as you may from time to time reasonably request of an amended Prospectus or a supplement to the Prospectus which will correct such statement or omission or effect such compliance, and in case any Underwriter is required to deliver a prospectus (or in lieu thereof, the notice referred to in Rule 173(a) under the Act) in connection with sales of any of the LP Units at any time nine months or more after the time of issue of the Prospectus, upon your request but at the expense of such Underwriter, to prepare and deliver to such Underwriter as many written and electronic copies as you may request of an amended or supplemented Prospectus complying with Section 10(a)(3) of the Act;

(d) To make generally available to its securityholders as soon as practicable, but in any event not later than sixteen months after the effective date of the Registration Statement (as defined in Rule 158(c) under the Act), an earnings statement of the Company and its subsidiaries (which need not be audited) complying with Section 11(a) of the Act and the rules and regulations of the Commission thereunder (including, at the option of the Company, Rule 158);

(e) During the period commencing on the date hereof and ending 45 days after the date hereof (the “Lock-Up Period”), not to offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose, except as provided hereunder, of any securities of the Company that are substantially similar to the LP Units, including but not limited to any options or warrants to purchase Common Units or any securities that are convertible into or exchangeable for, or that represent the right to receive, Common Units or any such substantially similar securities (other than pursuant to employee and/or director equity plans existing on, or upon the conversion or exchange of convertible or exchangeable securities outstanding as of the date of this Agreement or as described in the Prospectus), without Credit Suisse’s prior written consent; and

(f) Until the earlier of two years from the date hereof or the attainment by the Company of “Well-Known Seasoned Issuer” status as defined under the Act, to furnish to its unitholders as soon as practicable after the end of each fiscal year an annual report (including a balance sheet and statements of income, partners’ capital and cash flows of the Company and its consolidated subsidiaries certified by independent public accountants) and, as soon as practicable after the end of each of the first three quarters of each fiscal year (beginning with the fiscal quarter ending after the effective date of the Registration Statement), to make available to its unitholders consolidated summary financial information of the Company and its subsidiaries for such quarter in reasonable detail; provided, however, that the Company will be deemed to have satisfied the requirements of this paragraph (f) if the Company files with or furnishes to the Commission the reports, documents or information required by Section 13 or 15(d) of the Exchange Act.

6. (a) Each of the CVR Parties, jointly and severally, represents and agrees that, without the prior consent of the Representatives, it has not made and will not make any offer relating to the LP Units that would constitute a “free writing prospectus” as defined in Rule 405 under the Act; each Underwriter severally, and not jointly, represents and agrees that, without the prior consent of the Company and the Representatives, it has not made and will not make any offer relating to the LP Units that would constitute a free writing prospectus; the Company and the Representatives agree that any such free writing prospectus the use of which has been consented to by the Company and the Representatives is listed on Schedule IIB hereto;

(b) The Company has complied and will comply with the requirements of Rule 433 under the Act applicable to any Issuer Free Writing Prospectus, including timely filing with the Commission or retention where required and legending; and

(c) The Company agrees that if at any time following issuance of an Issuer Free Writing Prospectus any event occurred or occurs as a result of which such Issuer Free Writing Prospectus would conflict with the information in the Registration Statement, the Pricing Prospectus or the Prospectus or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances then prevailing at the time of such issuance, not misleading, the Company will give prompt notice thereof to the Representatives and, following such notice, if requested by the Representatives, will prepare and furnish without charge to each Underwriter an Issuer Free Writing Prospectus or other document that will correct such conflict, statement or omission; provided, however, that this covenant shall not apply to any statements or omissions in an Issuer Free Writing Prospectus made in reliance upon and in conformity with information furnished in writing to the Company by an Underwriter through the Representatives expressly for use therein.

7. The Company covenants and agrees with the several Underwriters to pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Company’s counsel and accountants in connection with the registration of the LP Units under the Act and all other expenses in connection with the preparation, printing, reproduction and filing of the Registration Statement, any Preliminary Prospectus Supplement, any Issuer Free Writing Prospectus and the Prospectus and amendments and supplements thereto and the mailing and delivering of copies thereof to the Underwriters and dealers; (ii) all expenses in connection with the qualification of the LP Units for offering and sale under state securities laws as provided in Section 5(b) hereof, including the reasonable fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the blue sky memorandum; (iii) the filing fees incident to, and the reasonable fees and disbursements of counsel for the Underwriters in connection with, any required review by FINRA of the terms of the

It is understood, however, that the Company shall bear the cost of any other matters not directly relating to the sale and purchase of the LP Units pursuant to this Agreement. Coffeyville Resources covenants that it will pay or cause to be paid the underwriting commissions and discounts and transfer taxes, if any, incident to the sale and delivery of the LP Units to be sold by Coffeyville Resources to the Underwriters hereunder. It is understood, however, that, except as provided in this Section 7, and Sections 9 and 13 hereof, the Underwriters will pay all of their own costs and expenses, including the fees of their counsel, stock transfer taxes on resale of any of the LP Units by them, and any advertising expenses connected with any offers they may make.

8. The obligations of the Underwriters hereunder, as to the LP Units to be delivered at each Time of Delivery, shall be subject, in their discretion, to the condition that all representations and warranties and other statements of the CVR Parties herein are, at and as of such Time of Delivery, true and correct, the condition that the CVR Parties shall have performed all of their respective obligations hereunder theretofore to be performed, and the following additional conditions:

(i) On or after the Applicable Time (i) no downgrading shall have occurred in the rating accorded any debt securities or preferred stock of the Company or Operating LLC or in the corporate rating of the Company or Operating LLC by any “nationally recognized statistical rating organization”, as that term is defined for purposes of Section 3(a)(62) under the Exchange Act, and

9. (a) The CVR Parties, jointly and severally, (i) will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus Supplement, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any “issuer information” (in the case of either an Issuer Free Writing Prospectus or such “issuer information,” taken together with the Pricing Prospectus) filed or required to be filed pursuant to Rule 433(d) under the Act, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and (ii) will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the CVR Parties shall 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 or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus Supplement, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives for use therein.

(b) Each Underwriter, severally and not jointly, will indemnify and hold harmless the CVR Parties against any losses, claims, damages or liabilities to which the CVR Parties may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus Supplement, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission to state therein 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 the Registration Statement, any Preliminary Prospectus Supplement or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use therein; and will reimburse the CVR Parties for any legal or other expenses reasonably incurred by the CVR Parties in connection with investigating or defending any such action or claim as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably 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 shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim 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 any indemnified party.

(d) If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the CVR Parties on the one hand and the Underwriters on the other from the offering of the LP Units. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the CVR 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 (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the CVR 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 CVR Parties bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. 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 CVR Parties on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The CVR Parties and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (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 above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in 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 such action or claim. Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the LP Units underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 10(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 subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint. No party shall be liable for contribution under this subsection (d) except to the extent and under such circumstances as such party would have been liable for indemnification under this Section 9 if such indemnification were available or enforceable under applicable law.

(e) The obligations of the CVR Parties under this Section 9 shall be in addition to any liability which the CVR Parties may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Act, each broker-dealer affiliate of any Underwriter and any selling agent of any Underwriter; and the obligations of the Underwriters under this Section 9 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to the respective officers and directors of the CVR Parties (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company) and to each person, if any, who controls the CVR Parties within the meaning of the Act.

10. In making a claim for indemnification under Section 9 of this Agreement (other than for any legal or other expenses reasonably incurred in connection with investigating or defending any action or claim in accordance with clause (a)(ii) of Section 9 (“Expense Reimbursement”), as further provided below) or contribution under Section 9 of this Agreement, by any of the CVR Parties, an indemnified party may proceed against either (1) all of the CVR Parties jointly or (ii) the Company, Managing GP and Operating LLC jointly, but may not proceed solely against Coffeyville Resources. Notwithstanding the provisions of Section 9 of this Agreement, in making a claim for indemnification under Section 9 (other than for an Expense Reimbursement), or contribution under Section 9, by any of the CVR Parties, as a precondition to any indemnified party obtaining indemnification or contribution from Coffeyville Resources for any loss, claim, damage, liability or expense under Section 9, such indemnified party shall first obtain a final judgment from a trial court that such indemnified party is entitled to indemnity or contribution under this Agreement with respect to such loss, claim, damage, liability or expense (the “Indemnity Final Judgment”) from the Company, Managing GP, Operating LLC and Coffeyville Resources (or any of them) and shall seek to satisfy such Indemnity Final Judgment in full from the Company, Managing GP and Operating LLC by making a written demand upon the Company, Managing GP and Operating LLC for such satisfaction. If such Indemnity Final Judgment shall remain unsatisfied in whole or in part 45 days following the date of receipt by the Company, Managing GP and Operating LLC of such demand, any indemnified party shall have the right to take action to satisfy such Indemnity Final Judgment by making demand directly on Coffeyville Resources (but only if and to the extent the Company, Managing GP or Operating LLC have not already satisfied such Indemnity Final Judgment, whether by settlement, release or otherwise). The indemnified parties may exercise this right to first seek to obtain payment from the Company, Managing GP and Operating LLC and thereafter obtain payment from Coffeyville Resources without regard to the pursuit by any party of its rights to the appeal of such Indemnity Final Judgment. The indemnified parties shall, however, be relieved of their obligation to first obtain an Indemnity Final Judgment, seek to obtain payment from the Company, Managing GP and Operating LLC with respect to such Indemnity Final Judgment or, having sought such payment, to wait such 45 days after failure by the Company, Managing GP and Operating LLC to immediately satisfy any such Final Judgment if (i) the Company, Managing GP or Operating LLC files a petition for relief under the United States Bankruptcy Code (the “Bankruptcy Code”), (ii) an order for relief is entered against the Company, Managing GP or Operating LLC in an involuntary case under the Bankruptcy Code and such order is not dismissed within 60 days after the filing thereof, (iii) the Company, Managing GP or Operating LLC makes an assignment for the benefit of its creditors or (iv) any court orders or approves the appointment of a receiver or custodian for the Company, Managing GP or Operating LLC or a substantial portion of any of their assets and such appointment is not discharged within 60 days after the effective date thereof. The foregoing provisions of this paragraph are not intended to

require any indemnified party to obtain an Indemnity Final Judgment against the Company, Managing GP, Operating LLC or Coffeyville Resources before obtaining any Expense Reimbursement. However, the indemnified parties shall first seek to obtain Expense Reimbursement in full from the Company, Managing GP and Operating LLC by making a written demand upon the Company, Managing GP and Operating LLC for such Expense Reimbursement. If such expenses shall remain unreimbursed in whole or in part 45 days following the date of receipt by the Company, Managing GP and Operating LLC of such demand, any indemnified party shall have the right to receive Expense Reimbursement from Coffeyville Resources by making written demand directly on Coffeyville Resources (but only if and to the extent the Company, Managing GP or Operating LLC have not already satisfied the demand for such Expense Reimbursement, whether by settlement, release or otherwise). The indemnified parties shall, however, be relieved of their obligation to first seek to obtain such Expense Reimbursement in full from the Company, Managing GP and Operating LLC or, having made written demand therefor, to wait such 45 days after failure by the Company, Managing GP and Operating LLC to immediately reimburse such expenses if (i) the Company, Managing GP or Operating LLC files a petition for relief under the Bankruptcy Code, (ii) an order for relief is entered against the Company, Managing GP or Operating LLC in an involuntary case under the Bankruptcy Code, (iii) the Company, Managing GP or Operating LLC makes an assignment for the benefit of its creditors or (iv) any court orders or approves the appointment of a receiver or custodian for the Company, Managing GP or Operating LLC or a substantial portion of any of their assets.

11. (a) If any Underwriter shall default in its obligation to purchase the LP Units which it has agreed to purchase hereunder at a Time of Delivery, you may in your discretion arrange for you or another party or other parties to purchase such LP Units on the terms contained herein. If within thirty-six hours after such default by any Underwriter you do not arrange for the purchase of such LP Units, then the Company and Coffeyville Resources shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to you to purchase such LP Units on such terms. In the event that, within the respective prescribed periods, you notify the Company and Coffeyville Resources that you have so arranged for the purchase of such LP Units, or the Company and Coffeyville Resources notify you that it has so arranged for the purchase of such LP Units, you or the Company and Coffeyville Resources shall have the right to postpone such Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in your opinion may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section 11 with like effect as if such person had originally been a party to this Agreement with respect to such LP Units.

(b) If, after giving effect to any arrangements for the purchase of the LP Units of a defaulting Underwriter or Underwriters by you and the Company and Coffeyville Resources as provided in subsection (a) above, the aggregate number of such LP Units which remains unpurchased does not exceed one-eleventh of the aggregate number of all the LP Units to be purchased at such Time of Delivery, then Coffeyville Resources shall have the right to require each non-defaulting Underwriter to purchase the number of LP Units which such Underwriter agreed to purchase hereunder at such Time of Delivery and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of LP Units which such Underwriter agreed to purchase hereunder) of the LP Units of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the LP Units of a defaulting Underwriter or Underwriters by you and the Company and Coffeyville Resources as provided in subsection (a) above, the aggregate number of such LP Units which remains unpurchased exceeds one-eleventh of the aggregate number of all the LP Units to be purchased at such Time of Delivery, or if Coffeyville Resources shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase LP Units of a defaulting Underwriter or Underwriters, then this Agreement (or, with respect to any Option Time of Delivery, the obligations of the Underwriters to purchase and of the Company to sell the Optional LP Units) shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company or Coffeyville Resources, except for the expenses to be borne by the Company and Coffeyville Resources and the Underwriters as provided in Section 7 hereof and the indemnity and contribution agreements in Section 9 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

12. (a) The respective indemnities, agreements, representations, warranties and other statements of the CVR Parties and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, or the CVR Parties, or any officer or director or controlling person of any of the CVR Parties, and shall survive delivery of and payment for the LP Units.

(b) In making a claim for breach by the CVR Parties of any agreement, representation or warranty contained in this Agreement, any Underwriter may proceed against either (i) all of the CVR Parties jointly or (ii) the Company, Managing GP and Operating LLC jointly, but may not proceed solely against Coffeyville Resources. As a precondition to any Underwriter obtaining recovery of any loss, claim, damage, liability or expense from Coffeyville Resources arising out of, or based upon or resulting from such breach, such Underwriter shall first obtain a final judgment from a trial court that such

Underwriter is entitled to recovery under this Agreement with respect to such loss, claim, damage, liability or expense (the “Breach Final Judgment”) from the Company, Managing GP, Operating LLC and Coffeyville Resources (or any of them) and shall seek to satisfy such Breach Final Judgment in full from the Company, Managing GP and Operating LLC by making a written demand upon the Company, Managing GP and Operating LLC for such satisfaction. If such Breach Final Judgment shall remain unsatisfied in whole or in part 45 days following the date of receipt by the Company, Managing GP and Operating LLC of such demand, any Underwriter shall have the right to take action to satisfy such Breach Final Judgment by making demand directly on Coffeyville Resources (but only if and to the extent the Company, Managing GP or Operating LLC have not already satisfied such Breach Final Judgment, whether by settlement, release or otherwise). The Underwriters may exercise this right to first seek to obtain payment from the Company, Managing GP and Operating LLC and thereafter obtain payment from Coffeyville Resources without regard to the pursuit by any party of its rights to the appeal of such Breach Final Judgment. The Underwriters shall, however, be relieved of their obligation to first obtain a Breach Final Judgment, seek to obtain payment from the Company, Managing GP and Operating LLC with respect to such Breach Final Judgment or, having sought such payment, to wait such 45 days after failure by the Company, Managing GP and Operating LLC to immediately satisfy any such Breach Final Judgment if (i) the Company, Managing GP or Operating LLC files a petition for relief under the Bankruptcy Code, (ii) an order for relief is entered against the Company, Managing GP or Operating LLC in an involuntary case under the Bankruptcy Code and such order is not dismissed within 60 days after the filing thereof, (iii) the Company, Managing GP or Operating LLC makes an assignment for the benefit of its creditors or (iv) any court orders or approves the appointment of a receiver or custodian for the Company, Managing GP or Operating LLC or a substantial portion of any of their assets and such appointment is not discharged within 60 days after the effective date thereof.

(c) Notwithstanding anything in this Agreement to the contrary, Coffeyville Resources’ aggregate liability pursuant to the indemnity and contribution provisions of Section 9 hereof and for any breach by Coffeyville Resources or any CVR Partners Entity of any agreement, representation or warranty contained in this Agreement shall not exceed an amount equal to the product of (x) the number of LP Units sold by Coffeyville Resources and (y) the per LP Unit net proceeds to Coffeyville Resources, as set forth in the Pricing Prospectus.

13. If this Agreement shall be terminated pursuant to Section 11 hereof, the CVR Parties shall not then be under any liability to any Underwriter except as provided in Sections 7 and 9 hereof; but, if for any other reason any LP Units are not delivered by or on behalf of the Company as provided herein (other than due to the failure to satisfy any of the conditions provided in clauses (i), (iii), (iv) or (v) of Section 8(j) hereof), the CVR Parties will cause the Company to reimburse the

Underwriters through you for all out-of-pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the LP Units not so delivered, but the CVR Parties shall not then be under any further liability to any Underwriter except as provided in Sections 7 and 9 hereof.

14. In all dealings hereunder, you, as the Representatives, shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by all of the Underwriters jointly or by, or on behalf of, the Representatives on behalf of the Underwriters.

15. All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to Credit Suisse Securities (USA) LLC, Eleven Xxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: ECM Syndicate Desk, telephone (000) 000-0000, facsimile (000) 000-0000 on behalf of the Representatives; and if to the CVR Parties shall be delivered or sent by mail, telex or facsimile transmission to the address of the Company set forth in the Registration Statement, Attention: Senior Vice President, General Counsel and Secretary, with a copy, which shall not constitute notice, to Fried, Frank, Harris, Xxxxxxx & Xxxxxxxx LLP, Xxx Xxx Xxxx Xxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: Xxxxxxx X. Xxxxxx; provided, however, that any notice to an Underwriter pursuant to subsection 9(c) hereof shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire, or telex constituting such Questionnaire, which address will be supplied to the Company by you upon request; provided, however, that notices under subsection 9(c) shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to Credit Suisse Securities (USA) LLC, Eleven Xxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: ECM Syndicate Desk, telephone (000) 000-0000, facsimile (000) 000-0000 on behalf of the Representatives; Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

16. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters and the CVR Parties and, to the extent provided in Sections 9 and 12 hereof, the officers and directors of the CVR Parties and each person who controls the CVR Parties or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the LP Units from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

17. Time shall be of the essence of this Agreement. As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

18. The CVR Parties acknowledge and agree that (i) the purchase and sale of the LP Units pursuant to this Agreement is an arm’s-length commercial transaction between the CVR Parties, on the one hand, and the several Underwriters, on the other; (ii) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of any of the CVR Parties; (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of any of the CVR Parties with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising any of the CVR Parties on other matters) or any other obligation to any of the CVR Parties except the obligations expressly set forth in this Agreement; and (iv) the CVR Parties have consulted their own legal and financial advisors to the extent they deemed appropriate. The CVR Parties agree that they will not claim that the Underwriters, or any of them, have rendered advisory services of any nature or respect, or owe a fiduciary or similar duty to any of the CVR Parties in connection with such transaction or the process leading thereto.

19. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the CVR Parties and the Underwriters, or any of them, with respect to the subject matter hereof.

20. This Agreement and any claim, controversy or dispute relating to or arising out of this Agreement shall be governed by and construed in accordance with the laws of the State of New York. The CVR Parties, severally and not jointly, agree that any suit or proceeding arising in respect of this Agreement and any claim, controversy or dispute relating to or arising out of this Agreement or our engagement will be tried exclusively in the U.S. District Court for the Southern District of New York or, if that court does not have subject matter jurisdiction, in any state court located in The City and County of New York and the CVR Parties, severally and not jointly, agree to submit to the jurisdiction of, and to venue in, such courts.

21. Each of the CVR Parties and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

22. This Agreement may be executed by any one or more of the parties hereto 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 instrument.

It is understood that your acceptance of this letter on behalf of each of the Underwriters is pursuant to the authority set forth in a form of Agreement

among Underwriters, the form of which shall be submitted to the Company for examination upon request, but without warranty on your part as to the authority of the signers thereof.
