2. Subject to the terms and conditions herein set forth, (a) the Company agrees to issue and sell to each of the Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Company, at a purchase price per Common Unit of $14.88 (which is equal to the initial public offering price of $16.00 per Common Unit less underwriting discounts and commissions of $1.12 per Common Unit comprising an underwriting discount of $1.04 per Common Unit and a structuring fee of $0.08 per Common Unit payable to ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. Incorporated and Barclays Capital Inc.), 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, the Company agrees to issue

and sell to each of the Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Company, 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.

The Company hereby grants to the Underwriters, severally and not jointly, the right to purchase at their election up to 2,880,000 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. The Representatives 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 you to the Company, 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 you but in no event earlier than the First Time of Delivery or, unless you and the Company otherwise agree in writing, earlier than two or later than ten business days after the date of such notice.

3. Upon the authorization by you 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 the Representatives may request upon at least forty-eight hours’ prior notice to the Company shall be delivered by or on behalf of the Company to the Representatives, through the facilities of The Depository Trust Company (“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 the Company to the Representatives 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 April 13, 2011 or such other time and date as the Representatives and the Company 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 the Representatives in the written notice given by the Representatives of the Underwriters’ election to purchase such Optional LP Units, or such other time and date as the Representatives and the Company 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 9 hereof, including the cross receipt for the LP Units and any additional documents requested by the Underwriters pursuant to Section 9(i) hereof, will be delivered at the offices of Fried, Frank, Harris, ▇▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP, ▇▇▇ ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇ (the “Closing Location”), and the LP Units will be delivered electronically via the facilities of DTC, all at such Time of Delivery.

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 your prior written consent; provided, however, that if (1) during the last 17 days of the initial Lock-Up Period, the Company releases earnings results or announces material news or a material event or (2) prior to the expiration of the initial Lock-Up Period, the Company announces that it will release earnings results during the 15-day period following the last day of the initial Lock-Up Period, then in each case the Lock-Up Period will be automatically extended until the expiration of the 18-day period beginning on the date of release of the earnings results or the announcement of the material news or material event, as applicable, unless the Representatives waive, in writing, such extension; the Company will provide the Representatives and each unitholder subject to the Lock-Up Period pursuant to the lockup letters described in Section 8(k) with prior notice of any such announcement that gives rise to an extension of the Lock-up Period;

(f) Until the earlier of three 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;

(g) To use the net proceeds received by it from the sale of the LP Units pursuant to this Agreement in the manner specified in the Pricing Prospectus under the caption “Use of Proceeds”;

6. (a) The Company 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 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 the Company represents that it has satisfied and agrees that it will satisfy the conditions under Rule 433 under the Act to avoid a requirement to file with the Commission any electronic road show; 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.

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 and each broker-dealer affiliate 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. (a) The CVR Parties, jointly and severally, agree to indemnify and hold harmless ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, each person, if any, who controls ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act and each affiliate of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ within the meaning of Rule 405 of the Act (the “▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities”) from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) (i) caused by any untrue statement or alleged untrue statement of a material fact contained in any material prepared by or with the consent of any of the CVR Parties for distribution to Participants in connection with the Directed Unit Program or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) caused by the failure of any Participant to pay for and accept delivery of Directed Units that the Participant agreed to purchase; or (iii) related to, arising out of, or in connection with the Directed Unit Program, other than losses, claims, damages or liabilities (or expenses relating thereto) that are finally judicially determined to have resulted from the bad faith or gross negligence of the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities.

(b) In case any proceeding (including any governmental investigation) shall be instituted involving any ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity in respect of which indemnity may be sought pursuant to Section 10(a), the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity seeking indemnity, shall promptly notify the Company in writing and the Company, upon request of the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity, shall retain counsel reasonably satisfactory to the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity to represent the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity and any others the Company may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity unless (i) the Company shall have agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity and any of the CVR Parties and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. None of the CVR Parties, in respect of the legal expenses of the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities in connection with any proceeding or related proceedings in the same jurisdiction, shall be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities. Any such separate firm for the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities shall be designated in writing by ▇▇▇▇▇▇ ▇▇▇▇▇▇▇. None of the CVR Parties shall be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, such CVR Party agrees to indemnify the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time a ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity shall have requested any CVR Party to reimburse it for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, such CVR Party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such CVR Party of the aforesaid request and (ii) such CVR Party shall not have reimbursed the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity in accordance with such request prior to the date of such settlement. None of the CVR Parties shall effect, without the prior written consent of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, any settlement of any pending or threatened proceeding in respect of which any ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity is or could have been a party and indemnity could have been sought hereunder by such ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity, unless such settlement includes an unconditional release of the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities from all liability on claims that are the subject matter of such proceeding.

(c) To the extent the indemnification provided for in Section 10(a) is unavailable to a ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then the CVR Parties, jointly and severally, in lieu of indemnifying the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity thereunder, shall contribute to the amount paid or payable by the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity as a result of such losses, claims, damages or liabilities (i) in such proportion as is

appropriate to reflect the relative benefits received by the CVR Parties on the one hand and the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities on the other hand from the offering of the Directed Units or (ii) if the allocation provided by clause 10(c)(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 10(c)(i) above but also the relative fault of any of the CVR Parties on the one hand and of the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities on the other hand in connection with any statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the CVR Parties on the one hand and the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities on the other hand in connection with the offering of the Directed Units shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Directed Units (before deducting expenses) and the total underwriting discounts and commissions received by the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities for the Directed Units, bear to the aggregate public offering price of the Directed Units. If the loss, claim, damage or liability is caused by an untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact, the relative fault of the CVR Parties on the one hand and the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement or the omission or alleged omission relates to information supplied by any of the CVR Parties or by the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(d) The CVR Parties and the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities agree that it would not be just or equitable if contribution pursuant to this Section 10 were determined by pro rata allocation (even if the CVR Parties and the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities were treated as one entity, respectively, for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 10(c). The amount paid or payable by the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by the ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 10, no ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity shall be required to contribute any amount in excess of the amount by which the total price at which the Directed Units distributed to the public were offered to the public exceeds the amount of any damages that such ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity has otherwise been required to pay. The remedies provided for in this Section 10 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(e) The indemnity and contribution provisions contained in this Section 10 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any

▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity or any of the CVR Parties, their officers or directors or any person controlling such CVR Party and (iii) acceptance of and payment for any of the Directed Units.

11. In making a claim for indemnification under Section 9 or 10 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 or the first sentence of Section 10 (“Expense Reimbursement”), as further provided below) or contribution under Section 9 or 10 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 Sections 9 and 10 of this Agreement, in making a claim for indemnification under Section 9 or 10 (other than for an Expense Reimbursement), or contribution under Section 9 or 10, by any of the CVR Parties, as a precondition to any indemnified party, including any ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity, obtaining indemnification or contribution from Coffeyville Resources for any loss, claim, damage, liability or expense under Section 9 or 10, 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.

12. (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 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 that you have so arranged for the purchase of such LP Units, or the Company notifies you that it has so arranged for the purchase of such LP Units, you or the Company 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 12 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 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 the Company 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 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 the Company 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, except for the expenses to be borne by the Company 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.

13. (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 Sections 9 and 10 hereof and for any breach by the CVR Parties of any agreement, representation or warranty contained in this Agreement shall not exceed an amount equal to the sum of (x) (i) the proceeds of the offering of the Firm Units that the Company distributes to Coffeyville Resources, (ii) the portion of the term loan under the New Credit Facility that the Company distributes to Coffeyville Resources and (iii) an amount equal to the total of the Company’s cash and cash equivalents on the Company’s consolidated balance sheet as of the day immediately preceding the First Time of Delivery that the Company distributes to Coffeyville Resources, as certified in writing to the Representatives by the chief financial officer of the Company or Managing GP as

of the First Time of Delivery, and (y) an amount, if any, equal to the purchase price paid by the Underwriters for Optional LP Units to the extent any of such proceeds are distributed to Coffeyville Resources.

14. If this Agreement shall be terminated pursuant to Section 12 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(i) 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.

15. 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 the Representatives on behalf of the Underwriters.

16. 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 you as the Representatives to each of (i) ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. Incorporated, Attention Global Capital Markets Syndicate Desk, ▇▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇; (ii) Barclays Capital Inc., ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, Attention: Syndicate Registration (Facsimile: 646-834-8133); and (iii) ▇▇▇▇▇▇▇, Sachs & Co., ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, Attention: Registration Department (Facsimile: 212-902-9316), with a copy, in the case of any notice pursuant to Section 13 hereof, to the Director of Litigation, Office of the General Counsel, Barclays Capital Inc., ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇; if to ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ in connection with the Directed Unit Program shall be delivered or sent by mail, telex or facsimile transmission to ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. Incorporated, Attention Global Capital Markets Syndicate Desk, ▇▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇; and if to the Company shall be delivered or sent by mail, telex or facsimile transmission to the address of the Company set forth in the Registration Statement, Attention: Secretary; 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 you as the Representatives to each of (i) ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co.

Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

17. 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 13 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.

18. 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.

19. 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 it 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.

20. 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.

21. This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

22. 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, including the Transactions.

23. 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.

If the foregoing is in accordance with your understanding, please sign and return to us two counterparts hereof, and upon the acceptance hereof by you, on behalf of each of the Underwriters, this letter and such acceptance hereof shall constitute a binding agreement among each of the Underwriters and the CVR Parties. 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.
