BOC shall promptly notify Coffeyville Resources thereof, specifying the particular contaminant levels and the effect thereof. Upon receipt of such notice, Coffeyville Resources shall, at its election within sixty (60) days thereafter proceed to do one of the following: (i) correct such condition by removal or modification of the contaminant source; (ii) request BOC to make such additions or modifications to the BOC Facility as BOC deems reasonably necessary to compensate for such Hazardous Condition, whereupon BOC shall undertake to do the same; or (iii) terminate this Agreement by providing written notice to BOC and paying to BOC the applicable termination fee listed on Exhibit I hereto. The cost of any action taken pursuant to the preceding sentence other than the payment of a termination fee by Coffeyville Resources pursuant to clause (iii) of such sentence shall be (x) borne by Coffeyville Resources if Coffeyville Resources was the cause of the Hazardous Condition, (y) borne by BOC if BOC was the cause of the Hazardous Condition, and (z) in all other cases borne equally by BOC and Coffeyville Resources.

     (i) Neither Coffeyville Resources nor BOC shall do or suffer anything to be done whereby the BOC Plant Site or the Facilities or any part thereof may be encumbered by any mechanics’ lien or other similar lien and if whenever and as often as any mechanics’ lien, or other similar lien is filed against the BOC Plant Site or the Facilities or any part thereof purporting to be for or on account of any labor, materials or services furnished in connection with any work in or about the BOC Plant Site or the Facilities done by, for or under the authority of either party hereto or anyone claiming by, through or under such party, such party shall discharge the same of record within sixty (60) days after the date of filing. Notwithstanding the above, each party hereto shall have the right to contest any such mechanics’ lien or other similar lien if within said sixty (60) day period stated above it notifies the other party in writing of its intention so to do and, if requested by the other party, deposits with such party a bond in favor of such party, with a surety company acceptable to such party as surety, in the total sum of at least one hundred twenty-five percent (125%) of the amount of the lien claim so contested, indemnifying and protecting such party from and against any liability, loss, damage, cost and expense of whatever kind or nature growing out of or in any way connected with said lien and the contest thereof, and if, and provided further, such party diligently prosecutes such contest, at all times effectively stays or prevents any official or judicial sale of the BOC Plant Site or the Facilities, or any part thereof or interest therein, under execution or otherwise, and pays or otherwise satisfies any final judgment adjudging or enforcing such contested lien claim and thereafter promptly procures record release or satisfaction thereof.

     (j) BOC shall have 360 days from and after any expiration or termination of this Agreement to remove the Facilities from the BOC Plant Site. BOC shall restore the BOC Plant Site to the condition it was in immediately prior to the time it was made available to BOC by Coffeyville Resources’ predecessor, Farmland Industries, Inc., but not including removing any foundations or other underground installations, and upon said removal of the Facilities, such foundation and underground installations shall become the property of Coffeyville Resources.

     (k) Coffeyville Resources, for itself and its duly authorized representatives and agents, reserves the right, upon reasonable notice to BOC, to enter the BOC Plant Site during the term of this Agreement for the purpose of (i) examining and inspecting the same as permitted hereunder and for the purpose of exercising any and all of Coffeyville Resource’s other rights under this Agreement, (ii) performing, at Coffeyville Resources’ option, such work in and about the BOC Plant Site as may be made necessary by reason of BOC’s default under any of the provisions of this Agreement, (iii) conducting environmental assessment, monitoring or compliance activities, and (iv) for such other purposes as Coffeyville Resources may reasonably determine to be necessary or appropriate. Coffeyville Resources may, during the progress of said work and activities mentioned in (ii) and (iii) above, keep and store on the BOC Plant Site all necessary materials, supplies and equipment, and Coffeyville Resources shall not be liable for any inconvenience, annoyances, disturbance, loss of business or other damage suffered by reason of the performance of any such work or by the storage of materials, supplies and equipment or by Coffeyville Resources’ exercise of any of its rights under this Agreement, except to the extent caused by the negligence of Coffeyville Resources or its representatives or agents.

     (1) BOC will consult with Coffeyville Resources and use all reasonable efforts to coordinate scheduled maintenance and other temporary scheduled interruptions in the operations of the Facilities during periods of scheduled down time for the Coffeyville Facilities.

     (m) BOC shall cooperate with Coffeyville Resources and any and all third parties at the Coffeyville Plant Site to coordinate the activities of all parties working at the Coffeyville Plant Site. Coffeyville Resources shall have the right, from time to time, to designate a contractor, agent or other representative of Coffeyville Resources’ choice to coordinate the activities of all contractors working on or near the BOC Plant Site or in connection with the Gasification Project. BOC shall cooperate with all such coordination efforts and shall take such steps as may be reasonably required for the orderly progress of the Gasification Project without interruption or disruption attributable to the acts or omissions of BOC. Coffeyville Resources and BOC shall, in general, and to the best of their ability, conduct their respective operations on or near the BOC Plant Site in such a manner as to cause no interference or disruption with the other’s operations. BOC acknowledges that Coffeyville Resources intends to operate the Coffeyville Facilities twenty-four (24) hours a day, seven days a week, during the time that BOC is performing its obligations hereunder, and BOC shall undertake its obligations hereunder in a manner that does not interrupt or disrupt the operations of the Coffeyville Facilities.

SECTION 3 PURCHASE AND SALE OF PRODUCT

     (a) It is anticipated that the BOC Plant will be operated on a continuous basis during the Supply Period and will produce a uniform volume of Product. From time to time Coffeyville Resources will advise BOC of the volume of Product it will purchase from BOC, such advice to be effective until new advice is given by Coffeyville Resources. Coffeyville Resources shall pay BOC for such Product in accordance with the provisions of Section 4 hereof. In the event Coffeyville Resources desires to take delivery of less Product than that amount described in Paragraph II of Exhibit A hereto, then Coffeyville Resources will continue to pay BOC for such Product in accordance with the provisions of Section 4 hereof, provided, however, that in the event that Coffeyville Resources desires to purchase less Product than that amount described in Paragraph II of Exhibit A for a period of more than twenty-four (24) hours, then the Supply Period shall be extended by that number of hours that is equal to the number of hours for which Coffeyville Resources desires to take delivery of less Product than that amount described in Paragraph II of Exhibit A, but not to exceed 180 days, and there shall be no Minimum Product Charge during such extension period.

     (b) (i) During the Supply Period, BOC shall sell and deliver to Coffeyville Resources, and Coffeyville Resources shall purchase and accept from BOC, Coffeyville Resources’ requirements of Product for its Gasification Project located at the Coffeyville Plant Site; provided, however, that BOC shall not be obligated to supply gaseous Oxygen Product or gaseous Nitrogen Product from the BOC Plant to Coffeyville Resources at an instantaneous flow rate in excess of the applicable rate that is stated in Paragraph II of Exhibit A or vaporized liquid Oxygen Product or vaporized liquid Nitrogen Product from the Liquid Product Storage Facility at a rate in excess of the applicable vaporization capacity set forth in Paragraph III of Exhibit A.

Delivery and transfer of title to all Product shall be made at the point where each of the Coffeyville Pipelines are connected to the corresponding BOC Pipelines.

          (ii) BOC’s delivery commitments to Coffeyville Resources, as stated in Paragraph 3(b) (i) above, shall be satisfied, primarily, by the delivery of gaseous Product produced at the BOC Plant; however, if the BOC Plant is not operating, or Coffeyville Resources’ requirements exceed the capacity of the BOC Plant, BOC will then supply Coffeyville Resources with vaporized liquid Product delivered from the inventory of the Liquid Product Storage Facility. If requested by Coffeyville Resources, BOC will replenish the inventory of the Liquid Product Storage Facility with hauled-in liquid product to the extent available from outside sources (“Supplemental Product”). Supplemental Product shall be billed to Coffeyville Resources as set forth in Paragraphs IV and V of Exhibit G.

          (iii) During the Supply Period, Coffeyville Resources shall not purchase any Oxygen Products or Nitrogen Products for any other use at the Coffeyville Plant Site from any third party except as set forth in section 3(d) below.

     (c) In the event that during the Supply Period BOC elects to produce Product in excess of the amount of Product to be purchased by Coffeyville Resources hereunder for the purpose of retaining, marketing and selling such Product for its own account pursuant to Section 5 hereof, BOC shall pay Coffeyville Resources any incremental cost Coffeyville Resources incurs in order to provide sufficient quantities of those items provided by Coffeyville Resources pursuant to Section 2(f) hereof to allow BOC to produce such excess Product.

          For the purposes of this Section 3(c), Coffeyville Resources’ incremental costs for liquid Oxygen Product and liquid Nitrogen Product retained by BOC for its own account and sold to third parties shall be deemed paid in full upon the credit to Coffeyville Resources by BOC of the following amounts:

(***) per ton of such liquid Oxygen Product
(***) per ton of such liquid Nitrogen Product

BOC shall meter all quantities of such liquid Product on BOC’s truck scales and shall calculate and provide to Coffeyville Resources all credits due to Coffeyville Resources therefor on a monthly basis. Coffeyville Resources will apply those credits against BOC’s invoices for the Minimum Product Charge.

     (d) If at any time during the Supply Period Coffeyville Resource’s requirements for Product exceed, or are expected to exceed, any of the instantaneous flow rates set forth in Paragraph II of Exhibit A by an amount which exceeds such instantaneous flow rate by at least 10 percent (the amount of such excess over and above 10% defined herein as “Excess Product”), then:

          i. Coffeyville Resources shall promptly provide BOC with written notice (“Excess Product Notice”) of the need for such Excess Product in accordance with Section 15 of this Agreement. Such Excess Product Notice shall include the approximate quantity of Excess

Product and the approximate date by which Coffeyville Resources requires such Excess Product (“Excess Product Date”); and

          ii. For 60 days following BOC’s receipt of such Excess Product Notice, BOC and Coffeyville Resources shall work together to jointly develop and request for Proposal (“RFP”) for the purpose of soliciting bids from third parties and BOC for supplying Excess Product to the Coffeyville Facilities by the Excess Product Date. BOC and Coffeyville Resources agree that it is their mutual intention that the RFP will not provide for the solicitation of bids for the sale of equipment, but will be limited to contracts for the supply of Excess Product; and

          iii. Coffeyville Resources shall have 60 days from the date BOC and Coffeyville Resources complete preparation of the RFP to distribute the RFP and solicit bids from BOC and any third party bidders (“Bidding Period”); provided, however, that if BOC and Coffeyville fail to complete the RFP by the time described in Section 3(d)(ii) above, then Coffeyville Resources may submit its own RFP to BOC and third parties and the 60 day Bidding Period would then start on the date of Coffeyville Resources’ distribution of such RFP; and

          iv. Within 7 days after the conclusion of the Bidding Period, Coffeyville Resources shall provide BOC with written notice (“Bid Decision Notice”), in accordance with Section 15 of this Agreement, as to whether: (a) it agrees to accept BOC’s bid; or (b) intends to accept one of the bids submitted by a third party; and

          v.  If Coffeyville Resources accepts BOC’S bid, then Coffeyville Resources shall purchase its Excess Product from BOC as of the Excess Product Date in accordance with the terms and conditions of BOC’s bid; and

(***)

SECTION 4 PRICING AND PAYMENT

     (a) Except as otherwise provided herein, Coffeyville Resources shall pay BOC in accordance with the pricing schedule set forth on Exhibit G hereto.

     (b) On or before the 10th day of each month, BOC shall submit an invoice (each, a “Minimum Product Charge Invoice”) to Coffeyville Resources covering the Minimum Product Charge applicable to such month. All Minimum Product Charge Invoices shall be on a net cash basis, payable by Coffeyviile Resources within twenty (20) days after receipt thereof. In the event BOC has not received payment within forty (40) days of the date of a Minimum Product Charge Invoice, BOC at its sole option may assess interest thereon at an annual rate equal to the prime rate then in effect at Chase Manhattan Bank, N.A., plus two percent (2%) from and after the date such payment was due to the date when paid.

     (c) On or before the 10th of each month, BOC shall submit an invoice (each, an “Other Charges Invoice”) to Coffeyville Resources covering all charges and other sums other than the Minimum Product Charge, if any, applicable to the immediately preceding month as well as all Product delivered prior to such month that was not covered by a prior invoice. All Other Charges Invoices shall be on a net cash basis, payable by Coffeyville Resources within ten (10) days after receipt thereof. In the event BOC has not received payment within thirty (30) days of the date of an Other Charges Invoice, BOC at its sole option may assess interest thereon at an annual rate equal to the prime rate then in effect at Chase Manhattan Bank, NA, plus two percent (2%) from and after the date such payment was due to the date when paid.

     (d) From time to time during the term of this Agreement, BOC shall have the right to increase the applicable unit prices for liquid Products in the pricing schedule set forth on Exhibit G hereto pursuant to this Section 4(d) by giving Coffeyville Resources written notice thereof. Said increased prices shall become effective thirty (30) days after the date of said notice; provided, however, that if Coffeyville Resources, within fifteen (15) days after the date of said notice, furnishes BOC with a bona fide, firm, written offer from a responsible seller offering to sell Coffeyville Resources comparable Product, in like quantities, under similar conditions and at a lower price, BOC shall within fifteen (15) days thereafter agree to either: (i) meet said lower price; or (ii) reinstate the price thereof in effect at the time of said notice of increase, whichever BOC, in its sole discretion, may elect.

     (e) During the Supply Period, Coffeyville Resources will provide a monthly credit to BOC for Lost Liquid Production (as “Lost Liquid Production” is defined below). The credit shall be calculated on a monthly basis using the following formula:

     ((***)/ton)[(Operating Days in Month)(120) — (Actual Tons Liquid Production)] = Credit

and will be capped at (***) in any single month. The (***)/ton price and (***)/month cap will adjust (up or down) on a monthly basis based upon the actual total power cost as billed to Coffeyville Resources by the City of Coffeyville, Kansas (expressed as $/KWH) compared to the actual total power cost in June 2005 (expressed as $/KWH).

          (i) “Operating Day” shall mean hours of operation in any calendar day during which BOC is providing all Products at the purity volumes and pressures provided for herein divided by 24.

          (ii) “Liquid Production” shall mean the sum of liquid Nitrogen Product and liquid Oxygen Product as determined by BOC scale tickets.

          (iii) “Lost Liquid Production” shall mean Liquid Production which is not realized by BOC solely due to the supply of High Pressure Air Product by BOC to Coffeyville Resources pursuant to this Agreement.

SECTION 5 ARGON, CO₂ BYPRODUCT AND OTHER BYPRODUCTS

     (a) During the Supply Period, BOC shall be entitled to retain, market and sell for its own account: (i) all Argon produced by the BOC Plant; (ii) all CO₂ Byproduct, except to the extent retained by Coffeyville Resources or its affiliates and except to the extent otherwise provided in or pursuant to Section 5(b) herein; and (iii) all other byproducts and other industrial gases, in liquid or gaseous form, produced by the BOC Plant, including Product in excess of BOC’s obligations to supply same to Coffeyville Resources hereunder. BOC shall be solely responsible for the proper disposal, in accordance with all applicable Environmental Laws and Permits of any and all byproducts and other emissions and wastes generated by the BOC Plant (including from CO₂ Byproduct delivered to BOC) other than Products delivered to Coffeyville Resources hereunder. Except as permitted by Section 5(b) herein, Coffeyville Resources agrees that it will not sell or deliver CO₂ Byproduct to anyone other than BOC, its affiliates and affiliates of Coffeyville Resources.

     (b) Subject to Paragraph 5(a) above, BOC and Coffeyville Resources hereby agree as follows:

          (i) For a period of no less than 90 days, commencing as of the effective date of this Agreement, which period shall be referred to as the “Initial Negotiating Period,” BOC and Coffeyville Resources shall negotiate in good faith to jointly develop projects relating to the marketing and sale of CO₂ Byproduct produced by the Coffeyville Facilities (“CO₂ Projects”) which are mutually acceptable to both parties. BOC and Coffeyville Resources further agree that each party can own up to a maximum of 50% of any individual CO₂ Project.

          (ii) If BOC and Coffeyville fail to jointly develop CO₂ Projects mutually acceptable to both parties during the Initial Negotiating Period, then, at any time after the expiration of the Initial Negotiating Period, either BOC or Coffeyville Resources (the “Proposing Party”) shall provide the other party (the “Receiving Party”) with written Notice of a Bona Fide Offer setting forth all terms of said Bona Fide Offer. Said Notice shall be provided in accordance with

Section 15 of this Agreement. A Bona Fide Offer may come from a third party, Coffeyville Resources or BOC.

          (iii) For a period of no less than 90 days, commencing as of the date written Notice of a Bona Fide Offer is received by the Receiving Party, BOC and Coffeyville Resources shall negotiate in good faith to consider the Bona Fide Offer. If BOC and Coffeyville Resources agree to accept the Bona Fide Offer, then, unless the parties agree otherwise, all profits, losses, tax credits and carbon sequestration credits earned in connection with the sale of CO₂ Byproduct associated with the Bona Fide Offer shall be shared between BOC and Coffeyville Resources in the same proportion as the ownership proposed in connection with the related Bona Fide Offer. If, at the expiration of 90 days, BOC and Coffeyville Resources have not reached agreement as to whether to accept or reject the Bona Fide Offer, then the Proposing Party shall be authorized to accept the Bona Fide Offer, and shall have the exclusive right to retain 100% of all profits, tax credits and losses earned in connection with the sale of CO₂ Byproduct to such Third Party Buyer. In that event, the Proposing Party shall indemnify and hold the Receiving Party, its directors, officers, agents, employees, subsidiaries, and affiliates, harmless from and against any and all claims, demands, judgments, liabilities or expenses arising out of or in any way connected with the Proposing Party’s use, transportation, marketing or sale of such CO₂ Byproduct.

SECTION 6 TAXES

     (a) Coffeyville Resources shall pay the amount of all Federal, state and local taxes, however denominated (except taxes on BOC’s net income or for its general privilege to conduct business in any state), arising in connection with the production, sale or delivery of any Product hereunder, including, without limitation, all real and personal property taxes (and any payments associated with such taxes) applicable to the Facilities, or any part thereof. BOC agrees to use its commercially reasonable best efforts to secure such exemptions from real and personal property taxes as may be available now and from time to time with respect to the BOC Facilities. BOC will cooperate with Coffeyville Resources should Coffeyville Resources desire to contest any sales or other tax assessed by any governmental unit, all at Coffeyville Resources’ expense.

     (b) In the event that any tax covered by this Section 6 should be assessed against and paid by a party other than the party required hereunder to pay such tax, such other party shall promptly reimburse such party for such payment

     (c) Upon request, a properly completed exemption certificate (where appropriate) for any tax from which a party claims exemption shall be provided to the other party.

SECTION 7 PRODUCT SPECIFICATIONS

     BOC warrants that all Products and gas sold and delivered to Coffeyville Resources under this Agreement shall conform to the product specifications set forth in Paragraph I of Exhibit A hereto. THE WARRANTY SET FORTH IN THIS PARAGRAPH 7 IS IN LIEU OF ALL OTHER WARRANTIES, REPRESENTATIONS OR CONDITIONS OF ANY KIND OR

NATURE, EXPRESS OR IMPLIED, IN FACT OR BY LAW, RESPECTING THE PRODUCTS AND GAS SOLD TO COFFEYVILLE RESOURCES.

SECTION 8 CLAIMS

     Written notice of all claims having anything to do with any Products delivered by BOC to the Coffeyville Pipelines or for failure to make timely delivery, shall be made within forty-five (45) days of such delivery, or of the date on which such delivery was to have been made, as the case may be. Written notice of all claims with respect to billing matters shall be made within one (1) year of the date of the relevant invoice. Failure by Coffeyville Resources to give such written notice within such time shall constitute a complete defense for BOC against such claims by Coffeyville Resources, except as otherwise specifically provided in Section 9 hereof.

SECTION 9 ALLOCATIONS OF RESPONSIBILITY

     (a) BOC shall bear the risk of loss with respect to all Product until Product is delivered by BOC to Coffeyville Resources under Section 3(b) hereof, at which time risk of loss shall pass to Coffeyville Resources.

     (b) Coffeyville Resources acknowledges that there are hazards associated with the use of Product. BOC will provide Coffeyville Resources with Material Safety Data Sheets setting forth the general hazards and safety information relating to Product. Coffeyville Resources hereby assumes all responsibility for warning its employees and its independent contractors exposed to Product of all such hazards and shall hold harmless and indemnify BOC from and against all liability arising from any failure to make such warnings, such indemnification to be subject to the provisions of Sections 19(e) and 19(f) hereof. BOC shall promptly notify Coffeyville Resources of any additional hazards of which BOC may, from time to time, become aware.

     (c) Final determination of the suitability of the Product (assuming such Product conforms to the specifications and other requirements of this Agreement) for any use contemplated by Coffeyville Resources is the sole responsibility of Coffeyville Resources, and BOC shall have no responsibility in connection therewith. Coffeyville Resources shall avail itself of testing devices to determine the purity of Product before Coffeyville Resources uses it at Coffeyville Resources’ discretion, but no error in, or failure to make, any such test shall impair any right on the part of Coffeyville Resources to pursue its remedies for breach of warranty hereunder.

     (d) BOC shall obtain, comply with and preserve in full force and effect all Permits necessary for the maintenance and operation of the BOC Facility. BOC shall cause all such Permits to be made available for inspection by Coffeyville Resources. Coffeyville Resources shall cooperate with BOC in obtaining and preserving all Permits necessary for the maintenance and operation of the BOC Facility and shall reimburse BOC for the actual cost of such Permits. BOC shall cooperate with Coffeyville Resources in obtaining and preserving any Permits necessary for the maintenance and operation of the Coffeyville Facilities. Prior to obtaining any Permit necessary for the maintenance or operation of the BOC Facility, BOC shall give

Coffeyville Resources notice thereof. If obtaining any Permit necessary for the maintenance or operation of the BOC Facility would have the direct or indirect effect of impairing Coffeyville Resources’ ownership, maintenance, operation and/or reasonably contemplated expansion of the Coffeyville Facilities, Coffeyville Resources shall give BOC notice thereof; and the parties shall cooperate to arrive at a fair and equitable resolution of such impairment.

     (e) BOC agrees to make such modifications to the BOC Facility as are required by governmental agencies or authorities, by the modification or change in interpretation of any applicable laws or Permits, or by the enactment or adoption of any new laws, so as to ensure that BOC’s maintenance and operation of the BOC Facility and Coffeyville Resources’ ownership, maintenance and operation of the Coffeyville Facilities, are in compliance therewith.

     (f) Other than any termination right Coffeyville Resources may have pursuant to the provisions of Section 13 hereof, Coffeyville Resources’ exclusive remedy for each unexcused failure on the part of BOC to deliver gaseous Product produced at the BOC Plant to Coffeyville Resources when required hereunder (including the delivery of gas that does not conform to the product specifications set forth in Paragraph I of Exhibit A hereto), whether or not such failure was caused, in whole or in part by any negligence, shall be to receive an abatement of the fees (together with any then applicable price adjustment) which Coffeyville Resources would otherwise have been obligated to pay to BOC pursuant to Section 4(a) of this Agreement from the date such failure occurs until such time as BOC resumes delivery of gaseous Product as required hereunder and all Products so delivered conform to the product specifications set forth in Paragraph I of Exhibit A hereto.

     (g) Other than any termination right Coffeyville Resources may have pursuant to the provisions of Section 13 hereof, Coffeyville Resources’ exclusive remedy for each unexcused failure on the part of BOC to deliver liquid Product from the Liquid Product Storage Facility or vaporized liquid product to Coffeyville Resources when required hereunder, whether or not such failure was caused, in whole or in part by any negligence, shall be to recover from BOC the difference between the cost to Coffeyville Resources of any reasonable purchase of Product in substitution for the Product that BOC so failed to deliver and the price of such quantity of Product hereunder, increased by any expenses incurred by Coffeyville Resources in connection with the procurement of the substitute Product and reduced by any expenses saved by Coffeyville Resources due to procurement of the substitute Product.

     (h) Other than any termination right Coffeyville Resources may have pursuant to the provisions of Section 13 hereof, Coffeyville Resources’ exclusive remedy for each unexcused failure or act on the part of BOC whereby liquid product or vaporized liquid product that does not conform to the product specifications set forth in Paragraph I of Exhibit A hereto is delivered from the Liquid Product Storage Facility to Coffeyville Resources, whether or not such failure or act was, in whole or in part, negligent, shall be to receive a refund of the price of such quantity of non-conforming product, or the replacement thereof with Product that does conform to said product specifications at no additional charge to Coffeyville Resources.

     (i) Except to the extent that BOC’s rights and obligations are materially adversely affected thereby, BOC shall provide all documents, reports, acknowledgments, consents to

assignments, certifications and other information reasonably requested by any person or entity, or group of persons or entities, extending credit or making any financial accommodations directly or indirectly to Coffeyville Resources, or for Coffeyville Resources’ benefit, for purposes of financing or refinancing in any manner any costs or expenses related to the construction, commissioning or operation of all or any part of the Gasification Project (each, a “Finance Party”). BOC shall cooperate with all Finance Parties to the fullest extent possible. BOC shall also enter into such amendments to this Agreement as Coffeyville Resources may reasonably request in order to comply with any requirements imposed by any Finance Party to the extent that BOC’s rights and obligations are not materially adversely affected thereby.

SECTION 10 METERS

     BOC shall install and maintain such metering as may be necessary hereunder. Such metering shall be inspected by BOC for accuracy at least once per year. In addition, such metering shall also be inspected and tested for accuracy at such other times as either party may reasonably elect. Coffeyville Resources shall be notified of the times such tests are to be made and may observe such tests. BOC shall bear the cost of all such tests, except those requested by Coffeyville Resources that show that the meter tested was accurate within two percent (2%). If any meter is found to be inaccurate by more than two percent (2%), any billings based on such meter shall be adjusted to offset such inaccuracy with respect to only those deliveries made during the thirty (30) day period prior to such test or during the latter half of the period of time since the said meter was last previously tested, whichever period of time is shorter.

SECTION 11 EXCUSED NON-PERFORMANCE

     (a) Any failure, in whole or in part, by either party timely to perform any obligation on its part to be performed under this Agreement (except the obligation to pay monies when due) shall be excused to the extent that such failure is caused by any circumstance which is not within the reasonable control of the party whose performance is prevented, restricted or otherwise interfered with, including without limitation, by any act of God, flood, storm, earthquake, fire, explosion, strikes, lockouts, industrial disputes or disturbances or other labor difficulty (regardless of the reasonableness of the demands of labor or the power of the party concerned to concede), riot, war, blockades, civil disorder, equipment breakdown or malfunction that was unavoidable through proper maintenance, failure of product machinery or transportation facilities that was unavoidable through proper maintenance, failure of or interference with utilities or other sources of supply, accident or by any order, request or decree of any governmental body or agency (each, a “Force Majeure”). Upon the occurrence of a Force Majeure, the party affected thereby shall give prompt written notice thereof to the other party.

     (b) Each time that, due to any Force Majeure, BOC delivers less Product than is required by Coffeyville Resources under Section 3(a) or Coffeyville Resources is unable to take any Product for five (5) or more consecutive full days, that portion of the Minimum Product Charge (together with any then applicable price adjustment) which Coffeyville Resources would otherwise have been obligated to pay to BOC pursuant to this Agreement that is apportionable to such full days shall be abated. (Said number of full days shall be determined by dividing twenty-four into the number of hours during which any such failure to deliver continued and

disregarding any fractional remainder). If either BOC or Coffeyville Resources so elects in writing, the Supply Period shall be extended for two times the number of full days with respect to which such Minimum Product Charge was so abated.

     (c) Subject to BOC’s obligations pursuant to Paragraph 2(1) hereof, BOC shall perform routine maintenance (scheduled and unscheduled) on the BOC Facility in accordance with generally accepted industry practices, and any such maintenance shall not be deemed a breach under this Agreement.

SECTION 12 PRICE ADJUSTMENTS

     Annually during the Supply Period, the Minimum Product Charge and the unit prices for gaseous Product purchased by Coffeyville Resources hereunder shall be subject to price adjustment by BOC as set forth in Exhibit B hereto.

SECTION 13 TERM

     (a) This Agreement shall be in effect from the date first set forth above to the expiration or termination of the Supply Period.

     (b) Either party shall have the right to terminate this Agreement in accordance with this Section 13(b) at any time in the event the other party fails to perform any material obligation hereunder for reasons other than a Force Majeure or as a direct result of a breach by the other party (a “Material Breach”). If either party (the “Other Party”) considers the other party (a “Breaching Party”) to have committed a Material Breach, the Other Party may give to the Breaching Party a notice of Material Breach stating the act or circumstances contended to be a Material Breach and the section of the Agreement alleged to have been breached, and demanding that the Material Breach be cured. If the Breaching Party fails to cure the Material Breach within thirty (30) days after receipt of the notice of Material Breach, the Other Party may terminate this Agreement upon thirty (30) days’ notice to the Breaching Party. If the nature of the Material Breach is such that it cannot be cured in thirty (30) days but a cure is commenced during such thirty (30) day period and diligently pursued thereafter, then such cure must be completed within 180 days from the date of notice of Material Breach, or the Other Party may terminate this Agreement on notice at any time after the expiration of such 180-day period unless such breach is then cured.

     (c) Either party shall have the right to terminate this Agreement upon written notice to the other party upon (i) any failure by the other party to satisfy any final judgment, decree or order against the other party which has not been stayed or appealed within thirty (30) days after the entry thereof and which would materially adversely affect the other party’s ability to perform its obligations under this Agreement if not so satisfied, stayed or appealed, or (ii) the other party shall (A) be or become insolvent or generally fail to pay its debts as they become due, or (B) voluntarily file a petition in bankruptcy or for reorganization under the United States Bankruptcy Code, or (C) have filed involuntarily against it a petition in bankruptcy or for reorganization under the United States Bankruptcy Code, which petition has not been stayed or dismissed within sixty (60) days after the filing thereof, or (D) voluntarily initiate any act, process or

proceeding under any insolvency law or other statute or law providing for the modification or adjustment of the rights of creditors, or (E) have initiated involuntarily against it any act, process or proceeding under any insolvency law or other statute or law providing for the modification or adjustment of the rights of creditors; which act, process or proceeding has not been stayed or dismissed within sixty (60) days after the initiation thereof, or (iii) the other party is a party to any merger or consolidation in which it is not the surviving entity or is dissolved or liquidated.

     (d) In the event that this Agreement is terminated by Coffeyville Resources pursuant to Section 13(b) or 13(c) hereof, Coffeyville Resources shall have the right and option to purchase the Facilities on an “as is” and “where is” basis from BOC at the applicable purchase price listed on Exhibit H hereto (such option shall be referred to herein as the “Option”). The term of the Option shall commence on the date of such termination and shall expire 180 days thereafter. Coffeyville Resources may exercise the Option by providing written notice to BOC of its election to exercise the Option. In the event that Coffeyville Resources elects to exercise the Option, BOC shall sell and convey to Coffeyville Resources, and Coffeyville Resources shall purchase from BOC, the Facilities. The closing of the purchase of the Facilities shall take place on a mutually agreeable business day within sixty (60) days following the date BOC receives Coffeyville Resources’ notice of its election to exercise the Option. At the closing, Coffeyville Resources shall pay BOC the purchase price (as calculated above), and BOC shall transfer and assign the Facilities to Coffeyville Resources and shall deliver to Coffeyville a bill of sale and such other appropriate instruments of transfer and physical possession as shall, in the reasonable opinion of counsel for Coffeyville Resources, be effective to vest in Coffeyville Resources good and marketable title to the Facilities.

SECTION 14 ASSIGNMENT

     This Agreement is not assignable by either BOC or Coffeyville Resources except upon the written consent of the other party; provided, however, that such consent shall not be unreasonably withheld. Notwithstanding the foregoing sentence, Coffeyville Resources may assign this Agreement as contemplated or required by its financing scheme or to an affiliate without the consent of BOC so long as BOC’s rights and obligations are not materially adversely affected thereby. The Parties agree that for purposes of this Section 14, BOC’s rights and obligations shall not be deemed to be materially adversely affected by an assignment so long as Coffeyville Resources remains secondarily liable under this Agreement following such assignment.

     (iii) There is no claim, litigation or proceeding pending or, to the best knowledge of such party, threatened against such party which, if decided adversely to such party, would preclude it from consummating the transactions contemplated hereby or performing the obligations hereunder or would subject the other party to any liability.

     (b) EXCEPT AS OTHERWISE SPECIFICALLY PROVIDED HEREIN, NEITHER PARTY HAS MADE ANY WARRANTIES, EXPRESS OR IMPLIED, AND SPECIFICALLY DISCLAIMS ANY WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

SECTION 17 CONFIDENTIALITY

     The parties acknowledge and agree that to the extent either party receives any proprietary or confidential information regarding operations of the other (“Confidential Information”), such Confidential Information represents valuable information to the party disclosing such Confidential Information (the “Disclosing Party’), and the party receiving such Confidential Information (the “Receiving Party’) agrees (a) not to disclose any Confidential Information of the Disclosing Party to any third party without the written consent of the Disclosing Party, (b) not to use any Confidential Information of the Disclosing Party for any purpose, other than to accomplish the transactions contemplated under this Agreement, without the prior written consent of the Disclosing Party, (c) to limit access to the Disclosing Party’s Confidential Information to the Receiving Party’s employees who are directly involved with the transactions described in this Agreement, (d) to inform each employee to whom the Disclosing Party’s Confidential Information is disclosed of the restrictions as to the use and disclosure of such confidential Information and to ensure that each such employee shall observe such restrictions, and (e) to return all of the Disclosing Party’s Confidential Information upon termination of this Agreement.

SECTION 18 RESOLUTION OF DISPUTES

     Except as otherwise specifically provided herein, the parties will in good faith attempt to resolve promptly and amicably any dispute (which term includes the failure to reach any agreement or grant any approval contemplated hereunder) between the parties arising out of or relating to this Agreement pursuant to this Section 18. In the event that a party to this Agreement has reasonable grounds to believe that the other party hereto has failed to fulfill any obligation hereunder, that its expectation of receiving due performance under this Agreement may be impaired, or that any other type of dispute between the parties arising out of or relating to this Agreement exists, such party will promptly notify the other in writing of the substance of its belief. The party receiving such notice must respond in writing within thirty (30) of receipt of such notice, which response must (i) provide evidence of cure of the condition specified or provide an explanation of why it believes that its performance is in accordance with the terms and conditions of this Agreement, and (ii) specify three (3) proposed dates, all of which must be within thirty (30) days from the date of the response, for a meeting to resolve the dispute. The claiming party will then select one (1) of the three (3) dates, and a dispute resolution meeting will be held on that date, which meeting shall be attended by a representative of each party with the power to settle the dispute and at which time the representatives shall engage in good faith discussions in an effort to resolve the dispute. If such representatives fail to resolve the dispute at such meeting, they will work together to resolve the dispute for a fifteen (15) day period following the meeting. If the dispute is not resolved within such fifteen (15) day period, the representatives shall refer the matter to the two individuals with primary operational responsibility for the respective parties at the level immediately subordinate to the respective chief executive officers of the parties. If such individuals fail to resolve the dispute within thirty (30) days, despite good faith attempts to do so, the parties will be free to pursue the remedies allowed under applicable law without prejudice. Regardless of the nature of the dispute that exists between the parties, both parties must continue to perform their obligations under this Agreement during any dispute resolution efforts.

SECTION 19 INDEMNIFICATION

     (a) BOC agrees to indemnify and hold Coffeyville Resources, its directors, officers, agents, employees, subsidiaries and affiliates (collectively, “Coffeyville Entities”) harmless from and against any and all claims, demands, judgments, liabilities or expenses for injury, sickness, disease or death to employees or other persons, or damage to property (subject to the limitations of Section 19(f) hereof) arising out of or in any way connected with BOC’s design, engineering, construction, installation, operation or maintenance of the BOC Facility or failure to comply with applicable laws or Permits related thereto or breach of any of the provisions of this Agreement. BOC agrees to defend, on behalf of the Coffeyville Entities, any suits, actions or proceedings arising out of or in any manner connected with any of the aforesaid causes and to reimburse the Coffeyville Entities for reasonable attorneys’ fees, settlements, losses, damages, satisfactions, costs or other expenses incurred by the Coffeyville Entities arising out of or in any manner connected with such suits, actions or proceedings. BOC’s obligation to indemnify, defend, reimburse and hold the Coffeyville Entities harmless shall extend to and include, but not be limited to, claims, demands, judgments, liabilities and expenses resulting from the personal injury, sickness, disease or death of any persons, regardless of whether BOC has paid the person

under the provisions of any workers’ compensation statute or law, or other similar federal or state legislation for the protection of employees. BOC’s indemnification obligations hereunder shall exclude any liabilities (i) arising from any breach for which exclusive remedies are otherwise provided hereunder or (ii) to the extent caused by the negligence of Coffeyville Resources, its employees, agents or subcontractors.

     (b) BOC shall, at its sole expense, defend any claims, suits, actions or proceedings brought against the Coffeyville Entities based on a claim that the design, engineering, construction, installation, operation or maintenance of the Facilities or the use of any equipment, process or technology, or any part thereof, furnished or manufactured by BOC or any of BOC’s agents or subcontractors under this Agreement constitutes any infringement of U.S. patents or copyrights or constitutes an improper use of any other proprietary rights (except where such infringement or improper use is caused by the use of the Facilities in combination with any other equipment or process not supplied by, on behalf, or at the request of BOC or any of BOC’s agents or subcontractors or previously agreed in writing by BOC) (an “Alleged Infringement”), and BOC shall pay all damages and costs awarded by a court of competent jurisdiction unappealed or unappealable against Coffeyville Resources, provided that BOC is notified promptly in writing of any such claim (except that the failure to promptly provide such notice shall not release BOC from such obligations except to the extent BOC is materially prejudiced thereby), shall be given adequate authority, information and assistance for the defense of same and shall have the full control of the defense of any such suit, action or proceeding. BOC’s obligation to pay damages and costs under the foregoing sentence shall only apply to the extent the Alleged Infringement is caused by BOC. Coffeyville Resources shall have the right to participate at its own expense. BOC agrees to reimburse the Coffeyville Entities for any claims, settlements, losses, damages, satisfactions, costs or other expenses incurred by the Coffeyville Entities arising out of or in any manner connected with such claims, suits, actions or proceedings, to the extent the Alleged Infringement is caused by BOC. At BOC’s option, and at its expense, BOC may: (a) procure the right to continue using the Facilities as contemplated under this Agreement; or (b) replace the Facilities with non-infringing equipment (or modify the Facilities), provided that such replaced or modified Facilities shall not differ functionally from the original Facilities in any material way.

     (c) Coffeyville Resources agrees to indemnify and hold BOC, its directors, officers, agents, employees, subsidiaries and affiliates (collectively, “BOC Entities”) harmless from and against any and all claims, demands, judgments, liabilities and expenses for injury, sickness, disease or death to employees or other persons, or damage to property owned by parties other than BOC Entities, arising out of or in any way connected with Coffeyville Resources’ design, engineering, construction, installation, operation or maintenance of the Coffeyville Facilities or failure to comply with applicable laws or Permits related thereto or breach of any of the provisions of this Agreement. Coffeyville Resources agrees to defend, on behalf of the BOC Entities, any suits, actions or proceedings arising out of or in any manner connected with any of the aforesaid causes and to reimburse the BOC Entities for reasonable attorneys’ fees, settlements, losses, damages, satisfactions, costs or other expenses incurred by the BOC Entities arising out of or in any manner connected with such suits, actions or proceedings. Coffeyville Resources’ obligation to indemnify, defend, reimburse and hold the BOC Entities harmless shall extend to and include, but not be limited to, claims, demands, judgments, liabilities and expenses

resulting from the personal injury, sickness, disease or death of any persons, regardless of whether Coffeyville Resources has paid the person under the provisions of any workers’ compensation statute or law, or other similar federal or state legislation for the protection of employees. Purchaser’s indemnification obligations hereunder shall exclude any liabilities (i) arising from any breach for which exclusive remedies are otherwise provided hereunder or (ii) to the extent caused by the negligence of BOC, its employees, agents or subcontractors.

     (d) Each Party agrees to defend, indemnify, and hold harmless the other Party from any loss, expense, claim, liability, demand or judgment arising out of or resulting from bodily injury to its employees while on property controlled by, and with the permission of, the other Party, except to the extent caused by the negligence of the other Party, its employees, agents or subcontractors.

     (e) A party entitled to indemnification under any provision of this Agreement is referred to herein as an “Indemnified Party,” and a party required to provide such indemnification is referred to herein as an “Indemnifying Party.” Promptly after receipt by an Indemnified Party of notice of the commencement of any action or the making of any claim, such Indemnified Party will, if a claim in respect thereof is to be made against the Indemnifying Party, notify the Indemnifying Party in writing thereof. In case any such action or claim is brought against any Indemnified Party, and it notifies the Indemnifying Party of the commencement or making thereof, the Indemnifying Party will be entitled to participate therein and, to the extent that the Indemnifying Party may elect by written notice to the Indemnified Party promptly after receiving the aforesaid notice from such Indemnified Party, to assume the defense thereof. Upon receipt of notice from the Indemnifying Party to such Indemnified Party of its election so to assume the defense of such action or claim, the Indemnifying Party will not be liable to such Indemnified Party under such indemnification for any legal or other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof.

     (f) NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY FOR ANY INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES UNDER ANY CIRCUMSTANCES, INCLUDING, WITHOUT LIMITATION, LOST PROFITS OR DAMAGES DUE TO LOSS OF USE OF A FACILITY OR INDIRECT OR CONSEQUENTIAL DAMAGES CAUSED BY OR ARISING OUT OF, IN WHOLE OR IN PART, ANY NEGLIGENT ACT OR OMISSION.

SECTION 21 TAKING & CASUALTY

     (a) In the event that the Facilities, or any material part thereof, shall be taken by any public authority or for any public use, or by the action of any public authority, then this Agreement may be terminated at the election of either BOC or Coffeyville Resources. Such

election shall be made by the giving of notice by one party to the other within thirty (30) days after the right of election accrues. For purposes of this subsection (a), what constitutes a “material part” of the Facilities shall be reasonably determined by BOC.

     In the event of such a taking, Coffeyville Resources shall be entitled to the entire award, except that BOC shall be entitled to receive any portion of the award made specifically for damages sustained to BOC’s equipment, trade fixtures, moving expenses, the unamortized cost of its leasehold improvements, or loss of any portion of its business.

     If neither BOC nor Coffeyville Resources exercises any right of election provided in this subsection (a), this Agreement shall continue in full force and effect and BOC shall proceed to diligently and expeditiously repair or rebuild the Facilities to as nearly as possible the same condition as prior to the taking; provided, however, that the Minimum Product Charge (together with any then applicable price adjustment) which Coffeyville Resources would otherwise have been obligated to pay to BOC pursuant to this Agreement shall be abated from the date of the taking until such time as the Facilities are so repaired or rebuilt. To the extent that the awards or payments are insufficient to repair or rebuild the Facilities, BOC shall bear all excess costs of repairing and rebuilding the Facilities.

     (b) In the event that the Facilities, or any material part thereof, shall be destroyed or damaged by fire or casualty, and such destruction or damage is so severe that, based on any reasonable estimates (which BOC shall deliver to Coffeyville Resources within thirty (30) days of such destruction or damage), the Facilities cannot be placed in proper condition for use within sixteen (16) months of the date of the fire or casualty, then this Agreement may be terminated at the election of BOC or Coffeyville Resources. Such election shall be made by the giving of notice by one party to the other within sixty (60) days after the right of election accrues. For purposes of this subsection (b), what constitutes a “material part” of the Facilities shall be reasonably determined by BOC.

     In the event of termination pursuant to this subsection (b), BOC shall be entitled to the entire sum of insurance proceeds attributable to the buildings, fixtures and other property which is not owned by Coffeyville Resources, which proceeds are received by either BOC or Coffeyville Resources in connection with the fire or other casualty. BOC shall be entitled to receive the proceeds of any insurance purchased by BOC to cover its personal property, equipment and business operations.

     If neither BOC nor Coffeyville Resources exercises any right of election provided in this subsection (b), this Agreement shall continue in full force and effect and BOC shall proceed to diligently and expeditiously repair or rebuild the Facilities to as nearly as possible the same condition as prior to the taking, damage or destruction, provided, however, that the Minimum Product Charge (together with any then applicable price adjustment) which Coffeyville Resources would otherwise have been obligated to pay to BOC pursuant to this Agreement shall be abated from the date of the fire or casualty until such time as the Facilities are so repaired or rebuilt. To the extent that the proceeds of insurance are insufficient to repair or rebuild the Facilities, BOC shall bear all excess costs of repairing and rebuilding the Facilities.
