to renew upon giving the other Party at least 24 Months written notice prior to the expiration of the Initial Term or the then current Renewal Term, as applicable.

Article III. Delivery and Acceptance

3.01 Sale by Coffeyville. Subject to the conditions and provisions of this Agreement, Coffeyville agrees to exclusively make available for sale and delivery, and to sell and deliver, to Chaparral, at the Title Transfer Point, the Contract Volume, but excluding any Permanently Released Volumes.

3.02 Purchase by Chaparral. Subject to the conditions and provisions of this Agreement, Chaparral agrees to purchase and accept from Coffeyville, at the Title Transfer Point, the Minimum Volume. Chaparral shall have the exclusive and ongoing right to purchase and accept from Coffeyville, at the Title Transfer Point, up to all of the Contract Volume, but excluding any Permanently Released Volumes, subject to the conditions and provisions of this Agreement.

3.03 CO₂ Bank. Notwithstanding the other provisions of Article III, to the extent a Shortfall Volume, Overage Volume or Supply Deficiency Volume is created during any Month during a Contract Year, a bank is hereby created (a “CO₂ Bank”) to net out such volumes over time.

(a) Shortfall Volume. In the event either (x) Chaparral fails to take the Monthly Minimum Volume from Coffeyville and a Shortfall Volume is created, or (y) Chaparral causes there to be Start Up Not Taken Volumes and a Shortfall Volume is created, then:

(i) first, such Shortfall Volume shall be netted concurrently against any Supply Deficiency Volume and any Overage Volume that are already in the CO₂ Bank, and

(ii) second, if after applying (i) above there exists a positive balance in the CO₂ Bank, then Chaparral shall pay Coffeyville for any remaining Shortfall Volume at the Contract Price in accordance with Article VIII of this Agreement and, as a result, such paid-for Shortfall Volume shall be added to the CO₂ Bank, and

(iii) thereafter, to the extent Chaparral takes volumes in excess of the Monthly Minimum Volume, Chaparral shall take such volumes free of charge to the extent of the remaining Shortfall Volume, and the Shortfall Volume in the CO₂ Bank shall be reduced by the corresponding amount.

(b) Supply Deficiency Volume. In the event Coffeyville fails to deliver the Monthly Minimum Volume and a Supply Deficiency Volume is created, then without payment or further action by Chaparral:

(i) first, such Supply Deficiency Volume shall be netted against any Shortfall Volume that may exist in the CO₂ Bank, and

- 10 -

(ii) second, if after applying (i) above there is any remaining Supply Deficiency Volume, then such remaining Supply Deficiency Volume shall be banked, and

(iii) thereafter, to the extent Coffeyville delivers volumes in excess of the Monthly Minimum Volume, the Supply Deficiency Volume in the CO₂ Bank shall be reduced by the corresponding amount.

(c) Overage Volume. In the event the Sales Volume purchased by Chaparral exceeds the Monthly Minimum Volume and an Overage Volume is created, then:

(i) first, such Overage Volume shall be netted against any Shortfall Volume that may exist in the CO₂ Bank, and

(ii) second, if after applying (i) above there is any remaining Overage Volume, then such remaining Overage Volume shall be banked.

(d) Accounting Method. Volumes coming in and going out of the CO₂ Bank shall be accounted for on a first in, first out basis.

(e) Time Limitation. No CO₂ volumes placed in the CO₂ Bank shall be banked for longer than a period of five (5) consecutive years. In the event such volumes remain in the CO₂ Bank at the end of such five (5) year period (“Balance To Be Settled”), then the Parties agree to cash balance the Balance To Be Settled at the Contract Price applicable at the times such volumes were banked.

(f) Example. An example of how the CO₂ Bank works is provided in Schedule 3.03(f) attached to this Agreement.

3.04 Carbon Credit Transfer. Notwithstanding the other provisions of Article III, the Parties agree to make the following assignments, conveyances or other transfers of Carbon Credits (or value thereof as described in Section 3.04(c) below) under the following conditions and provisions:

(a) Instances of Transfer. In the event of any of the following, the following Carbon Credits shall be assigned, conveyed or otherwise transferred from one Party to the other Party:

(i) If the Minimum Volume is less than or equal to 640,000 Short Tons and a Shortfall Volume is created during a Calendar Year, then Chaparral shall assign, convey or otherwise transfer to Coffeyville the number of Carbon Credits attributable to the Shortfall Volume.

(ii) If the Minimum Volume is greater than 640,000 Short Tons and a Shortfall Volume is created during a Calendar Year in which the Sales Volume is less than 640,000 Short Tons, then Chaparral shall assign, convey or otherwise transfer to Coffeyville the number of Carbon Credits

- 11 -

attributable to the difference between 640,000 Short Tons and the Sales Volume.

(iii) If the Minimum Volume is greater than 640,000 Short Tons and a Supply Deficiency Volume is created during a Calendar Year, then Coffeyville shall assign, convey or otherwise transfer to Chaparral the number of Carbon Credits attributable to the difference between the Minimum Volume and 640,000 Short Tons.

(b) Settlement of Transfers. Any transfer of Carbon Credits pursuant to Section 3.04(a) shall occur within 45 Days following (i) certification and registration of the Carbon Credits with a publicly-recognized registry, or (ii) such earlier period to the extent certification or registration is addressed and permitted by Applicable Law.

(c) Value Instead of Carbon Credits. In the event a Party is prohibited, or not permitted, by Applicable Law to actually and physically assign, convey or otherwise transfer any of the Carbon Credits as contemplated by Section 3.04(a), then in lieu of such transfer the equivalent monetary value thereof shall be paid from the one Party to the other Party. “Value” for this purpose shall be the market value of such Carbon Credits at the end of the Calendar Year for the vintage of such Carbon Credits.

3.05 Redelivered Volumes. Subject to Sections 3.05(a) through 3.05(c) below, Coffeyville shall have the right to elect, upon giving Chaparral at least 90 Days written notice, to receive any portion of the Contract Volume not taken by Chaparral (“Not Taken Volumes”), or any portion of any Permanently Released Volumes, or both (collectively “Redelivered Volumes”), at any point designated by Coffeyville on the Pipeline (each such point, a “Coffeyville Tie-In” and the effective date of Coffeyville’s affirmative election, the “Redelivery Date”).

- 13 -

(iii) During Contract Year 11 and thereafter, there shall be no timing or volume limitations or restrictions with respect to any PRV Election by Chaparral.

(c) Marketing of Permanently Released Volumes. Subject to Coffeyville’s compliance with its obligations in Section 3.05, Chaparral agrees that Coffeyville shall have the right to market any or all Permanently Released Volumes on the Pipeline. In the exercise of Coffeyville’s sole discretion, and then only if Chaparral agrees after Coffeyville so elects, the marketing of Permanently Released Volumes may be conducted jointly by the Parties.

Article IV. Price

4.01 Contract Price. Chaparral shall pay Coffeyville a price per MSCF (“Contract Price”) for the Sales Volume delivered hereunder as measured at the Measurement & Pricing Point, and the Contract Price is specified in more detail on Schedule 4.01.

4.02 Favored Nations Clause. Beginning with the sixth Contract Year and for the remainder of the Term thereafter, in the event the delivered price paid to Chaparral by the North Burbank Unit for delivery of the Contract Volume to such unit (“Chaparral Delivered Price”) is less than the delivered price paid by such unit for a CO₂ Stream from any source other than Coffeyville (“Other Delivered Price”) and such other-sourced CO₂ Stream (i) is at least 96.0 mole % CO₂ and (ii) is delivered at a pressure of at least 1,400 Psig, then the Contract Price under this Agreement shall be increased by the positive number resulting from the calculation below:

(a) Other Delivered Price;

(b) minus Contract Price hereunder as calculated in Schedule 4.01, as if this Section 4.02 did not exist; and

(c) minus the Tariff.

4.03 Measurement & Pricing Point. The volume of CO₂ taken by Chaparral (for purposes of determining the Sales Volume, and otherwise) shall be determined based on the volume of CO₂ measured at the sales meter at or near the outlet or tailgate of the CO₂ Facility (the “Measurement & Pricing Point”), and in accordance with the requirements contained herein, including specifically Article VII.

The Parties shall mutually work together to determine the most cost-efficient manner of designing the Feeder Line and the CO₂ Facility for the purpose of ensuring the highest pressure of the Contract Volume that can be reasonably obtained at the inlet of the CO₂ Facility; provided, final decision authority with respect to the Feeder Line will reside with Coffeyville, and final decision authority with respect to the CO₂ Facility will reside with Chaparral. In no event will either Party be required to take actions or incur additional expense in the design or construction of the Feeder Line or the CO₂ Facility that would exceed its obligations under this Agreement.

5.04 Right to Reject Nonconforming CO₂. Chaparral shall have the right to reject any portion of the Contract Volume delivered by Coffeyville hereunder that materially fails to meet either the Quality Specifications or Pressure Requirements, or both, for more than 36 consecutive hours or more than a collective total of 60 hours during a 7-consecutive-Day time period (“Nonconforming Volumes”). Chaparral shall not be obligated to take any Nonconforming Volumes.

(a) In the event the nonconformity giving rise to the Nonconforming Volumes continues for a period in excess of either 60 consecutive Days, or a collective total of 120 Days during any given Contract Year, then in such an event, Chaparral, at its sole option, shall have the right to terminate this Agreement and trigger the requirement of Coffeyville to pay Liquidated Damages as if all conditions contained in Section 9.05 for payment of Liquidated Damages were satisfied;

- 15 -

provided that such remedy shall only be available during the first four Contract Years of this Agreement.

(b) Subject to Section 5.04(c) below, Chaparral may in the exercise of its sole discretion elect to accept and take Nonconforming Volumes. In the event Chaparral elects to take any Nonconforming Volumes, then:

(i) Chaparral shall not be required to pay for any such taken Nonconforming Volumes; and

(ii) The Minimum Volume requirement for any Contract Year during which Chaparral elects to take any Nonconforming Volumes shall be reduced by the amount of any Nonconforming Volumes not taken by Chaparral.

(c) In the event that (i) changes or upgrades to the CO₂ Facility are necessary to process and purify the Nonconforming Volumes in order to maintain the mechanical integrity of the CO₂ Facility or the Pipeline, or to maintain the miscible process efficiency of the Fields (collectively, “Upgrades”); (ii) such Upgrades are in fact actually performed, conducted or implemented; (iii) such Upgrades result in the Nonconforming Volumes no longer being out of conformity but instead the Contract Volume at the Measurement & Pricing Point satisfies the Quality Specifications; and (iv) Coffeyville pays for 100% of the costs associated with the Upgrades, then Chaparral shall again be obligated to take, and shall be required to pay for, all such Sales Volumes.

(d) This Section 5.04 contains the sole and exclusive remedy of either Party in the event of Nonconforming Volumes.

Article VI. Feeder Line, Blower, CO₂ Facility,

6.07 Pipeline. Chaparral and its Affiliates shall be solely responsible for designing, manufacturing, procuring, permitting, fabricating, constructing, erecting, installing, owning, operating, maintaining and paying for the pipeline and all facilities, systems, valves, pump stations, and ancillary equipment relating thereto, to receive the Sales Volume from the CO₂ Facility at the boundary of the Site downstream of the Measurement & Pricing Point, and to deliver the Sales Volume to the Fields (collectively, the “Pipeline”).

6.08 Easements, Rights-of-Way, and Access.

(a) Coffeyville agrees to grant and convey to Chaparral or one of its Affiliates one or more easements and rights-of-way upon, over, across and under certain real property owned or under the control of Coffeyville (the “Easements”). The Easements will be on terms consistent with this Agreement and in a form mutually agreed upon by the parties. The Easements will be appurtenant to the Site, and will address (i) Chaparral’s access to the Site and utilities serving the CO₂ Facility, and (ii) Chaparral’s access and use of certain real property for purposes of placement, construction and/or maintenance of the Pipeline. The term of the Easements described in subpart (i) above, and the Easements described in subpart (ii) above, to the extent located on the site of the Fertilizer Plant, will run concurrently with the Term, and will prohibit assignment by Chaparral without the prior written consent of Coffeyville; provided that Coffeyville’s consent shall be deemed to have been given to permitted assignees of this Agreement.

(b) Coffeyville agrees to partially assign to Chaparral or one of its Affiliates one or more easements, rights-of-way, surface leases, surface agreements, permits, and licenses upon, over, across and under certain real property currently benefitting Coffeyville (the “Assignments”). The Assignments will be on terms consistent with this Agreement and in a form mutually agreed upon by the parties. The Assignments will address Chaparral’s access and use of certain real property for

- 19 -

purposes of placement, construction and/or maintenance of the Pipeline. Each of the Assignments will run for the duration of, and on the terms provided in, the underlying easement, right-of-way, etc., and will inure to the benefit of and be binding upon the Parties and their respective transferees, successors and assigns.

(c) Chaparral acknowledges and agrees that one or more of the Assignments may not allow for the placement, construction and/or maintenance of the Pipeline.

(d) Coffeyville and its Affiliates shall have the sole right to determine the placement or location of the Pipeline pursuant to any Assignment granted to Chaparral hereunder, but only after receiving and in good faith considering all recommendations, advice and counsel of Chaparral regarding such placement or location. Chaparral agrees that the placement, construction and/or maintenance of the Pipeline shall not interfere with the operation or maintenance of pipelines owned or operated by Coffeyville or its Affiliates.

6.09 Limitation on Use of CO₂. During the Term, Chaparral agrees to sell, assign or otherwise transfer all of the Sales Volume to the Fields. Chaparral agrees that it will not sell, assign or otherwise transfer any portion of the Sales Volume to a Person for purposes other than injection for enhanced oil recovery or geologic sequestration without (a) the prior written consent of Coffeyville, and (b) the payment to Coffeyville of reasonable consideration therefore, as may be mutually agreed upon by the Parties. Once any Sales Volume is sold by Coffeyville to Chaparral hereunder and Chaparral has fulfilled all of its obligations to Coffeyville with respect to such Sales Volume, then unless otherwise expressly stated in this Agreement, Coffeyville shall have no ownership interest in or right to the Sales Volume, including any such CO₂ that may be produced from the Fields.

Article VII. Measurement, Testing

and Volume Determination

7.01 Meter Stations. Buyer shall ensure that a measuring station for sales of Contract Volume delivered hereunder is installed, operated and maintained in accurate working order at the Measurement & Pricing Point, and at any Coffeyville Tie-In. The cost and expense of installing, operating and maintaining the measuring station at the Measurement & Pricing Point will be borne by Chaparral. The cost and expense of installing, operating and maintaining the measuring station at each Coffeyville Tie-In will be borne by Coffeyville in compliance with Section 3.05.

(a) Each such measuring station shall be equipped in accordance with the standards set forth in the American Petroleum Institute, Manual of Petroleum Measurement Standards, Chapters 14.3 and 21.1 and American Gas Association Report No. 3 and No. 9 (latest editions). Measurement equipment will be subject to change to allow use of improved technology under such standards. Pursuant to Section 7.01(b), Seller may elect for any measuring station to have a check meter installed in the adjoining piping circuit.

- 20 -

(b) Composition of the CO₂ Stream from the Fertilizer Plant, relative density, heating value, and other relevant values shall be determined by online chromatographic analysis or similar analytical device. One chromatograph or similar analytical device shall be installed at or near the Measurement & Pricing Point and interfaced with the electronic flow meter at the Measurement & Pricing Point. Another chromatograph or similar analytical device may be installed at or near the Title Transfer Point. Chromatographs/Devices shall be calibrated Monthly, unless agreed by the Parties otherwise, using standards representative of the streams being analyzed. If analysis is outside chromatograph/device design accuracy and repeatability, the chromatograph/device will require calibration that Day. At a minimum, each chromatograph/device must be tested and verified Monthly unless agreed by the Parties otherwise. This will require a minimum of three separate standards. Chromatographs/Devices shall be installed, operated, maintained and verified according to applicable industry standards (API 14.1, API 21.1, GPA 2261, GPA 2145, GPA 2172, and GPA 2177).

7.02 Seller’s Check Measuring Equipment. Seller, at Seller’s discretion, cost and expense, may install, maintain, and operate such check measuring equipment and check chromatograph or similar analytical device on the Contract Volume as it desires, provided that such check measuring equipment shall be so installed as not to interfere with the operation of the Buyer’s or Buyer’s agent’s measuring meters. Check measurement may be accomplished with either redundant meter tubes, or parallel meters on a single meter tube.

7.03 Meter Calibration and Meter Tests. Buyer shall ensure that the measurement equipment at the Measurement & Pricing Point and any Coffeyville Tie-In is accurate and in repair, and that such periodic tests of such equipment as Buyer may deem necessary are made as often as needed, but in no case shall the calibration interval exceed three Months; provided, Buyer agrees to perform additional calibrations at the request of Seller, and at Seller’s expense unless such requested calibration results in an adjustment greater than +/- 2.0%, in which case, Buyer will pay for the cost of the calibration. Buyer shall give Seller notice of each such calibration test in sufficient time to enable Seller, if it so chooses, to have its representative present. Buyer further agrees to furnish Seller with copies of all calibration results. If upon any such calibration the measuring equipment is found to be within 2.0% accurate, such equipment shall be considered correct in computing deliveries. If upon any calibration the measuring equipment shall be found to be inaccurate by any amount exceeding 2.0% error, repairs shall be made immediately at Buyer’s cost, and any previous reading of such equipment shall be corrected to zero error for any period which is known definitely or agreed upon, but in case the period is not known definitely or agreed upon, then for one-half (1/2) of the period of time elapsed since the date of the last calibration.

7.04 Measuring Equipment out of Service. If for any reason any measuring equipment is out of service or out of repair so that the volume of CO₂ purchased cannot be ascertained or computed from the reading thereof, the volume of CO₂ purchased during the period such equipment is out of service or out of repair shall be estimated using the first of the following methods which is feasible: (a) by using the registration of check equipment, if installed and accurately registering; (b) by correcting the error, if the percentage of error is ascertainable by calibration test or mathematical calculations; or (c) by estimating the volume of delivery, using

- 21 -

as a basis the volumes delivered during preceding periods under similar conditions when the equipment was registering accurately.

7.05 Volume Determination. The volume of CO₂ delivered at the Measurement & Pricing Point shall be determined as follows:

(a) The unit of measurement shall be MSCF.

(b) Metered volumes will be obtained by developing a meter factor at line conditions by use of a prover loop. A meter factor will be applied to the gross metered volume as set out below.

(c) The metered volume will be adjusted by the following formulas for the quality of CO₂ actually received:

(i) Actual CO₂ received (MSCF) = measured CO₂ (MSCF) times the Volume % CO₂

(ii) Volume % CO₂ = the volume % of CO₂ in the gas flow stream as measured by a chromatograph or similar analytical device installed at or near the Measurement & Pricing Point.

(d) The resulting net metered volume will then be multiplied by a constant and the measured density to obtain pounds-mass, which will then be converted to MSCFs.

Article VIII. Accounting and Payments

8.01 Sales Volume Statements. Buyer shall furnish Monthly statements or reports to Seller of actual Sales Volumes sold hereunder to Buyer (“Sales Volume Statements”) on or before the 10^th Day of the following Month. The Parties shall cooperate in determining the form of such Monthly statement.

8.02 Sales Invoices. Using the Sales Volume Statements, Seller shall invoice Buyer Monthly for all charges incurred during the preceding Month under this Agreement (each, a “Sales Invoice”). Buyer shall make payments of Sales Invoices by electronic funds transfer or by other mutually-agreeable method.

11.08 Incremental Costs.

(a) All costs and expenses associated with monitoring, measuring, verifying, certifying, registering and marketing Carbon Credits hereunder shall be apportioned in the same manner as the Carbon Credits.

(b) In the event Chaparral’s proportionate share of any costs and expenses described in Section 11.08(a) exceed the value to Chaparral of Chaparral’s proportionate share of the revenues from such Carbon Credits, then Chaparral may put such

- 28 -

Carbon Credits to Coffeyville at a price of $0 and all such costs and expenses associated with such Carbon Credits shall be put to Coffeyville in like manner.

(c) Notwithstanding the foregoing, in the event all or any portion of Chaparral’s Carbon Credits are put to Coffeyville pursuant to Section 11.08(b), and Coffeyville’s proportionate share (which may be 100%) of any costs and expenses described in Section 11.08(a) exceed the value to Coffeyville of the revenues or benefits from such Carbon Credits, then Coffeyville may, in its sole discretion, direct all Parties and the MMV Agent(s) to cease the creation of all or any portion of such Carbon Credits by cessation of the necessary monitoring, measuring, verifying, certifying or registering activities.

All Section 45Q Credits shall belong 100% to, or otherwise be retained by Coffeyville, and all other provisions in Sections 11.03 through 11.08 shall be equally applicable to the Section 45Q Credits so long as all benefits generated by and expenses mentioned in such other provisions shall also belong 100% to, or otherwise be retained by Coffeyville. To the extent Chaparral is required to incur any additional expenses as a result of Coffeyville seeking to obtain Section 45 Credits, and such expenses are above and beyond that which Chaparral is required to incur for purposes of the Carbon Credits or the EOR Credits, then Coffeyville agrees to reimburse Chaparral, at its actual cost without markup, for any such expenses; provided such expenses are approved in advance by Coffeyville, such approval not to be unreasonably withheld.

Notwithstanding anything to the contrary in this Agreement, to the extent a Governmental Authority provides tax incentives, credits, refunds, abatements or other remunerations related to using CO₂ specifically for the purpose of enhanced oil recovery or recovery of any natural resource, including a credit or other benefit associated with an Oil and Gas Tax, but excluding Section 45Q Credits (collectively, “EOR Credits”), and any Party to this Agreement can secure all or a portion of such EOR Credits, then 100% of such EOR Credits shall be conveyed to, or otherwise be retained by Chaparral, and all other provisions in Sections 11.03 through 11.08 shall be equally applicable to the EOR Credits so long as all benefits generated by and expenses mentioned in such other provisions shall also belong 100% to, or otherwise be retained by Chaparral. To the extent Coffeyville is required to incur any additional expenses as a result of Chaparral seeking to obtain EOR Credits, and such expenses are above and beyond that which Coffeyville is required to incur for purposes of the Carbon Credits or Section 45Q Credits, then Chaparral agrees to reimburse Coffeyville, at its actual cost without markup, for any such expenses; provided such expenses are approved in advance by Chaparral, such approval not to be unreasonably withheld.

(d) If a receiving party receives a request or is required by deposition, interrogatory, request for documents, subpoena, civil investigative demand or similar process, or is otherwise required by Applicable Law to disclose any part of the Confidential Information, then the receiving party agrees to (i) to the extent legally permitted, immediately notify the disclosing party in writing of the existence, terms and circumstances surrounding such a request or requirement, and (ii) assist the disclosing party in seeking a protective order or other appropriate remedy satisfactory to the disclosing party (at the expense of the disclosing party). If such protective order or other remedy is not obtained (or the disclosing party waives compliance with the provisions hereof), then (x) the receiving party may disclose that portion of the Confidential Information it is legally required to disclose, (y) the receiving party will exercise reasonable efforts to obtain assurance that confidential treatment will be accorded the Confidential Information to be disclosed, and (z) to the extent legally permitted, the receiving party will give written notice to disclosing party of the information to be so disclosed as far in advance of its disclosure as commercially reasonably practicable.

(e) The Parties acknowledge and agree that, in the event of any breach or threatened breach of this Section 13.05 by either Party or its Representatives, the other Party may be irreparably harmed and may not be made whole by monetary damages recoverable under this Agreement. Accordingly, in addition to any other remedy to which a Party may be entitled pursuant to this Agreement, and notwithstanding any other provision in this Agreement, a Party shall be entitled to seek an injunction to prevent breaches or threatened breaches of, or to compel specific performance of, the provisions of this Section 13.05.

(f) Upon termination of this Agreement, and only upon the request of the disclosing party, the receiving party will, and will direct its Representatives to, promptly return to the disclosing party all originals and copies of the disclosing party’s Confidential Information and any materials or data containing or derived therefrom, including hard copy and electronic records, and will purge from all computer storage devices (to the extent reasonably practicable) any image or copies of such Confidential Information, materials or data; provided the receiving party and its Representatives may retain one copy of Confidential Information to the extent required to comply with legal, regulatory or fiduciary obligations, subject to such party’s continuing obligations under this Agreement.

- 35 -

13.06 No Inconsistent Action. Each Party hereby covenants and agrees that it will not take any action which is materially inconsistent with its obligations under this Agreement, that would cause any representation to be untrue or misleading, that would make it impossible or impracticable for a condition herein to be satisfied, or that would materially hinder or delay the consummation of the transactions contemplated by this Agreement.

13.07 Permits. Each Party hereby covenants and agrees that it will maintain all material Permits that continue to be necessary in order for it to continue to conduct the Business as it is currently conducted in full force and effect, and will timely file all reports, statements, renewals applications and other filings that are required to keep such Permits in full force and effect, and will timely pay all fees and charges in connection therewith that are required to keep such Permits in full force and effect.

13.08 Update Permitted Liens. At least 90 Days, but no more than 120 Days prior to the Start Date, Chaparral will prepare and deliver to Coffeyville an updated Schedule 12.03(c), disclosing all Permitted Liens that would have been disclosed had they been known as of the Effective Date. The updated Schedule 12.03(c) will not reveal the occurrence or existence of any fact, event or condition not disclosed on Schedule 12.03(c) as of the Effective Date that has caused or is expected to cause a material adverse effect on either Party’s rights, duties or obligations pursuant to this Agreement.

13.09 Further Actions. Each Party hereby covenants and agrees that it will use all reasonable efforts to take, or cause to be taken, all appropriate action, and do, or cause to be done, all things necessary, proper or advisable under Applicable Laws or otherwise to consummate and make effective the transactions contemplated by this Agreement as promptly as practicable, including using all reasonable efforts to obtain all Permits as are necessary for the consummation of transactions contemplated herein and, to the extent reasonably requested by the Party entitled to a majority of any category of credits hereunder, taking all reasonable action for a Party to obtain the benefit of any credit that it is entitled to pursuant to this Agreement. In case at any time after the Effective Date any further action is necessary or desirable to carry out the purposes of this Agreement, each Party and the proper officers, directors and managers of each Party to this Agreement will use all reasonable efforts to take all such action.

Article XIV. Force Majeure

14.01 Force Majeure. In the event it is impracticable for either Party, wholly or in part, by reason of Force Majeure, to carry out its obligations under this Agreement (other than the obligation to make payments of any monies due hereunder), the obligations of the Parties to the extent affected by such Force Majeure shall be suspended; and the Party affected by the event of Force Majeure shall give prompt notice of the extent and expected duration of the Force Majeure and the particulars thereof as promptly as possible and confirm any such notice in writing. Any Party affected by Force Majeure shall use reasonable diligence to remedy any Force Majeure situation.

14.02 Force Majeure Defined. The term “Force Majeure” as employed herein means acts of God, by the elements, strikes, lockouts, differences with workmen, or other industrial or labor disturbances, act of the public enemy, wars, military operations, national emergency,

- 36 -

insurrections, riots, lightning, earthquakes, fires, storms, floods, high water, washouts, restraints of government, federal or State, civil or military and of people, acts or restrictions of civil or military authority or governmental offices acting under some chain of authority, by any governmental regulations, or any Applicable Law, or action of any court of the federal, state or local government, civil disturbances, explosions, regularly scheduled turnarounds, breakage or accident to machinery, equipment, tankage or lines of pipe, the necessity or desirability for making repairs to or alterations or maintenance of machinery, equipment, tankage or lines of pipe, loss of redelivery point, equipment or facility breakdown, freezing of wells or of pipelines, wellbore failures, uncontrolled surfacing of CO₂, and any cause or causes, whether the kind enumerated or otherwise, not reasonably within control of the Party claiming suspension in which by the exercise of reasonable diligence such Party will be unable wholly or in part to prevent or overcome. Such term shall likewise include: (a) in those instances where either Party hereto is required to obtain servitudes, rights-of-way grants, Permits to enable such Party to perform hereunder, the inability of such Party to acquire, or the delays on the part of such Party in acquiring, at reasonable cost and after the exercise of reasonable diligence, such servitudes, rights-of-way grants or Permits, and (b) in those instances where either Party hereto is required to furnish materials and supplies for the purpose of constructing or maintaining facilities or is required to secure Permits to enable such Party to perform hereunder, the inability of such Party to acquire, or delays on the part of such Party in acquiring, at reasonable cost and after the exercise of reasonable diligence, such materials and supplies or Permits; provided, however, the term “Force Majeure” does not mean or include any cause which by the exercise of reasonable diligence the Party claiming suspension could overcome. Settlement of strikes, lockouts or other labor disputes shall be entirely within the discretion of the Party having the difficulty and the above requirement that any Force Majeure must be remedied with all reasonable dispatch and must not be a cause which can be prevented by the exercise of reasonable diligence shall not require the settlement or prevention of strikes, lockouts or other labor disputes by acceding to the demand of opposing parties when such course is inadvisable in the sole discretion of the Party having the difficulty.

14.03 Extended Force Majeure. If, after deliveries have commenced hereunder, an event of Force Majeure affects the amounts of deliveries by Seller or the receipts by Buyer for a consecutive period of 180 Days, then, at any time after such period but prior to the time such event has been remedied, the other Party may, upon prior notice to the Party claiming Force Majeure and without further liabilities as to either Party hereunder, terminate this Agreement.

Article XV. Defaults and Remedies

15.01 Events of Default. Any one or more of the following events shall constitute an “Event of Default” by a Party:

(a) Failure or refusal to pay when due any sum when required by this Agreement to be paid by such Party pursuant to this Agreement;

(b) Unless due to Force Majeure, failure by Coffeyville to tender and deliver to Chaparral either (i) at least 50% of the Monthly Minimum Volume for any six Months (to be calculated on a Monthly basis) out of any period of 12 consecutive

- 37 -

Months, or (ii) at least 25% of the Monthly Minimum Volume for a period of 60 consecutive Days;

(c) Unless due to Force Majeure, failure by Chaparral to purchase and accept either (i) at least 50% of the Monthly Minimum Volume for any six Months (to be calculated on a Monthly basis) out of any period of 12 consecutive Months, or (ii) at least 25% of the Monthly Minimum Volume for a period of 60 consecutive Days;

(d) Unless due to Force Majeure, and except as provided in subsections (b) and (c) directly above, failure or refusal to observe, perform or otherwise comply with any other covenant, condition or agreement to be observed, performed or complied with by such Party pursuant to this Agreement, the Lease, an Easement, an Assignment, or other agreement between the Parties;

(e) Any representation or warranty made or deemed made by or on behalf of such Party in this Agreement or in any Exhibit or Schedule to this Agreement shall prove to have been incorrect, in any material respect, when made or deemed made; or

(f) Such Party is Bankrupt.

15.02 Notice as Precondition to Remedies. As a precondition to pursuing any Remedies for an alleged Event of Default by a Party, the other Party (the “Notifying Party”) shall, before pursuing any Remedies, give notice of default in writing (“Notice of Default”) to the allegedly defaulting party. Each Notice of Default shall specify in detail the alleged Event of Default.

15.03 Right to Cure Defaults.

(a) Except for the Event of Default described in Section 15.01(a) and (f), the alleged defaulting party shall have 30 Days after the Notice of Default is given by the Notifying Party to cure the Event of Default; provided that if the failure is not reasonably capable of cure within such 30 Days, then the alleged defaulting party shall diligently pursue the cure in good faith and the Parties shall agree on a reasonable time period for such cure but, in the absence of such an agreement, the alleged defaulting party shall not be afforded more than 60 Days after the Notice of Default is given by the Notifying Party to cure the Event of Default.

(b) For the Event of Default described in Section 15.01(a), the alleged defaulting party shall have 15 Days after the Notice of Default is given by the Notifying Party to cure the Event of Default.

15.04 Remedies. If any Event of Default by the allegedly defaulting party shall remain uncured after the time period allowed for cure in Section 15.03, the Notifying Party shall be entitled to exercise any rights and remedies provided by law or equity, and may specifically exercise one or more of the following rights and remedies, all of which are cumulative and not alternative:

- 38 -

(a) seek and receive injunctive relief or a decree of specific performance;

(b) suspend all performance of its own obligations hereunder; provided that if Chaparral is the Notifying Party and is continuing to receive any portion of the Contract Volume at the Title Transfer Point, then Chaparral may not so suspend payment for Sales Volumes actually taken at the Measurement & Pricing Point; and

(c) terminate this Agreement upon written notice to the allegedly defaulting party, such termination not constituting a waiver of any other remedy to which the Notifying Party may be entitled pursuant to this Agreement (including, if applicable, the Liquidated Damages).

15.05 Reasonableness of Liquidated Damages and Exclusive Remedies. The Parties acknowledge and agree that the terms, conditions and amounts fixed as Liquidated Damages and exclusive remedies in this Agreement are reasonable, considering the loss of revenues and the actual costs that either Party will incur if the other Party fails to satisfy the delivery and take obligations (as applicable) set forth in this Agreement. The amounts and terms of such Liquidated Damages and exclusive remedies are agreed upon and fixed hereunder by the Parties because of the difficulty of ascertaining the exact amount of losses and/or costs that will be actually incurred by Buyer or Seller in such event, and the Parties hereby agree that all such amounts are a reasonable estimate of Buyer’s or Seller’s probable loss (and are not a penalty) and that such amounts shall be applicable regardless of the amount of such lost revenues and increased costs actually incurred by such Party.

15.06 Termination. In addition to the Party’s termination rights pursuant to Section 15.04(c), this Agreement may be terminated at any time by mutual written agreement of the Parties.

15.07 Effect of Expiration or Termination. If this Agreement expires or is terminated as provided for in this Agreement, then all obligations under this Agreement will terminate and no Party hereto will have any liability in respect of the expiration or termination of this Agreement; provided that expiration or termination of this Agreement for any reason shall not affect or relieve:

(a) The Parties’ confidentiality obligations under this Agreement;

(b) Each Party’s payment obligations with respect to amounts due under this Agreement that are attributable to periods prior to such expiration or termination;

(c) Any Party’s indemnification obligations under this Agreement;

(d) Either party from liability for any willful breach of any representation, warranty, covenant or agreement set forth in this Agreement prior to such expiration or termination;

(e) A Party from liability for fraud, in which case the other Party will be entitled to exercise all remedies available under law or equity; and

- 39 -

(f) Any other obligations of either Party which by their nature are to be performed after the expiration or termination of this Agreement.

Each party agrees not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, any claim that it is not subject personally to the jurisdiction of such court, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court, and hereby agrees not to challenge such

- 43 -

jurisdiction or venue by reason of any offsets or counterclaims in any such suit, action or proceeding.

17.15 Waiver of Jury Trial.
