(a) the later of the date of Initial Full Production and the Tolling Commencement Date under that certain Tolling Agreement, dated of even date herewith, between Purchaser and Cokenergy, Inc., an Indiana corporation (“Cokenergy”); or

(b) January 1, 1999.

2.2 Renewal Option . Purchaser is hereby granted the right to renew the term of this Coke Purchase Agreement at a contract price that is mutually acceptable to both Purchaser and Seller. The contract price during any such renewal term will:

(a) be based on methodology for calculation substantially similar to that set forth herein at Article V;

(b) accommodate the Coke Plant’s need for new capital expenditures (calculated using a *****% after tax rate of return to Seller) and amortized over the remaining economically useful life of the Coke Plant; and

(c) enable Seller to realize the residual value as determined by the Computer Model attached hereto as Schedule 5.1(c), amortized over the remaining economically useful life of the Coke Plant.

At least twenty-four (24) months prior to the expiration of the Initial Term, Purchaser must give notice to Seller of Purchaser’s intent to renew, specifying a renewal term not less than three but not more than ten years in duration. Seller will reply within thirty (30) days following receipt of Purchaser’s notice of intent to renew, and in so replying Seller shall specify the required additional capital, the approximate projected economically useful life remaining and a proposed contract price for Coke in accordance with subsections 2.2(a), (b) and (c) above and the Parties hereby agree to use their commercially reasonable good faith efforts to negotiate a mutually

acceptable contract price to apply during such renewal term. If Purchaser fails to give notice of its intent to renew twenty-four (24) months prior to expiration of the Initial Term, such failure shall operate as a conclusive waiver of Purchaser’s right to renew.

ARTICLE III

Quantity

3.1 Take or Pay Basis . During the term of this Coke Purchase Agreement, and subject to the terms and conditions hereof (including without limitation, the provisions relating to Purchaser’s No. 7 Blast Furnace set forth in Article XI hereof), Seller shall sell and deliver, on a take or pay basis, and Purchaser shall buy and accept delivery of Coke from Seller on a take or pay basis , in the amount of the Minimum Coke Purchase Requirement for each relevant Contract Year period. Should Purchaser fail to take the Minimum Coke Purchase Requirement tendered for any monthly period, Purchaser shall nonetheless be obligated to pay the Contract Price for Purchaser’s Minimum Coke Purchase Requirement for such monthly period.

It is specifically understood that:

(a) Subject to the Force Majeure provisions herein contained, Seller’s contractual obligation hereunder is to sell Coke to Purchaser in the amount of the Minimum Coke Purchase Requirement without regard to the actual amount of Coke produced by the Coke Plant. To the extent practicable, Seller will satisfy its obligation to deliver the required Coke Tonnages with Coke produced at the Coke Plant.

(b) Should Seller fail to deliver approximately 21,000 Tons per week, for any period of two or more consecutive weeks, Purchaser shall have the right to secure such deficit from any other source and, in addition to any other rights and remedies hereunder, Purchaser shall be entitled to recover from Seller the amount, if any, by which the purchase price, together with any and all reasonable costs actually incurred by Purchaser in securing such substitute Coke exceeds the Contract Price determined without regard to Section 5.1(e).

(c) If Purchaser wrongfully rejects the Coke, Seller shall have the right to sell such Coke to third parties, and, in addition to any other rights and remedies hereunder, Seller shall be entitled to recover from Purchaser:

(1) A penalty in the amount of *****Dollars ($*****) per Ton for such wrongly rejected coke; and

(2) the full Contract Price of such rejected Coke net of resale proceeds, if any, (adjusted for handling losses) and sales of nut coke and breeze. The Purchaser shall not be

9

entitled to receive any discount described herein at Section 5.1(e) relating to Section 29 Tax Credits that may be available in connection with any resale by Seller of such rejected Coke to third parties.

(d) In the event that Seller is unable to satisfy its contractual obligation to deliver the Minimum Coke Purchase Requirement solely from Coke produced by the Coke Plant, Seller will provide Purchaser with advance written notice of such inability, together with an indication of whether or not Seller is reasonably likely to secure the deficit from a probable alternate source (and identification of any such probable alternate source, if possible). Seller will use commercially reasonable efforts to secure any such deficit from an identifiable producer. Such notice shall also include the delivered price for such Coke. Within five (5) days of its receipt of such notice from Seller, Purchaser will inform Seller in writing whether or not Purchaser will accept delivery from Seller of Coke meeting the Coke Quality Specifications, but not produced by the Coke Plant. If Purchaser elects not to accept delivery from Seller of such Coke produced by sources other than from the Coke Plant, Seller will be relieved of any delivery obligation under this Coke Purchase Agreement with respect to such Tonnage, and Purchaser will not be entitled to receive from Seller any reimbursement of costs incurred by Purchaser in securing substitute Coke other than a rebate equal to the lesser of (1) the excess, if any, of the delivered price of the substitute Coke proposed by Seller over the Contract Price, and (2) the excess ^- , if any, of the delivered price of the substitute Coke actually purchased by Purchaser over the Contract Price.

(e) Although the Parties anticipate that Coke purchased hereunder will be used for Purchaser’s own operation, Purchaser may resell to third parties as follows:

(1) Purchaser will notify Seller of the amount of Coke Purchaser desires to resell and Seller shall use its reasonable good faith efforts to obtain the most favorable price on any such resale and shall not discriminate against Purchaser in favor of any other party (including Seller) for whom Seller is selling coke. Within sixty (60) days of Purchaser’s notice, Seller shall notify Purchaser of the bona fide price at which Seller is able to sell such Coke (the “Proposed Price”), and in respect of any such resales, Purchaser shall pay Seller a commission (the “Commission”) in addition to the Contract Price equal to *****dollars per Ton ($*****per Ton) resold, but not greater than the excess, if any, of the resale price per Ton over the Contract Price per Ton.

(2) If Seller’s Proposed Price is unacceptable to Purchaser, then Purchaser may resell such Coke on its own account and pay Seller as the “Commission” an amount equal to

10

***** (*****) of the Commission that would have been payable to the Seller based upon the Proposed Price. Purchaser will use its reasonable good faith efforts to obtain a price that exceeds the Proposed Price.

(3) The Commission will be paid to Seller within five (5) Business Days of Purchaser’s receipt of payment for such resold Coke.

(4) If Seller does not provide Purchaser with a Proposed Price within sixty (60) days of Purchaser’s notice pursuant to Section 3.1(e)(1), then Purchaser may resell such Coke for its own account, and no Commission will be payable to Seller in respect of such resold Coke.

3.2 Option to Purchase Available Excess Production . Provided that Purchaser uses substantially all, but in no event less than ***** (*****) Tons of Minimum Coke Purchase Requirement Tonnage (or such lesser tonnage as actually produced by the Coke Plant) in any one Contract Year period (determined on a ratable basis during each Contract Year) for its No. 7 Blast Furnace or other facilities at its Indiana Harbor Works location, or such failure by Purchaser to use more than ***** (*****) Tons results solely from a Force Majeure event or planned furnace reline at Purchaser’s No. 7 Blast Furnace pursuant to Section 11.2, then Purchaser may, at its option, purchase and accept from the Seller, for Purchaser’s own use (and not for resale), and Seller shall sell and deliver to Purchaser, such additional quantities of Coke produced by the Coke Plant as may be available in excess of Purchaser’s Minimum Coke Purchase Requirement for the relevant Contract Year period. The purchase price per Ton for any such available excess Coke shall be equal to the Contract Price determined without regard to Section 5.1(e) hereof, less a discount equal to *****percent (*****%) *****.

Seller will notify Purchaser in writing approximately six (6) months prior to the beginning of each calendar quarter, as to the quantity of additional Coke, if any, reasonably expected to be available during such calendar quarter. In order to establish its right to purchase any such available additional quantities of Coke, the Purchaser must deliver to Seller written notice of its commitment to purchase the identified available excess quantities of Coke on or before the thirtieth (30th) day following Seller’s original notice to Purchaser. Delivery of such notice of commitment by the Purchaser shall be irrevocable and shall be binding on the Purchaser for all purposes of this Coke Purchase Agreement. If Seller does not receive Purchaser’s notice of commitment to purchase within such thirty (30) day period, Purchaser shall be deemed to have declined its option to purchase the available additional quantities of Coke previously identified by Seller. Any Tonnages of Coke purchased by Purchaser pursuant to the provisions of this Section 3.2, regarding Purchaser’s option to purchase excess production, shall not be counted towards those Tonnages of Coke needed to fulfill the Purchaser’s

11

Minimum Coke Purchase Requirement during any Contract Year period. In the event Purchaser declines additional or excess Coke pursuant to this Section 3.2 (or is not entitled to purchase such excess Coke), Seller shall be relieved of any obligation under this Coke Purchase Agreement to produce such additional or excess Coke.

In the event that Purchaser should resell to third parties ***** (*****) Tons or more of the Coke purchased under this Coke Purchase Agreement in any one Contract Year, Purchaser will have no option to purchase excess Coke produced at the Coke Plant during such Contract Year. Any excess Coke produced by the Coke Plant and not purchased by Purchaser for its own use pursuant to this Section 3.2 may be sold by Seller for its own account.

ARTICLE IV

Coke Quality

4.1 Coke Quality Specifications . All Coke purchased and sold under this Coke Purchase Agreement shall conform to the quality requirements set forth on Schedule 4.1 (the “Coke Quality Specifications”), based on Purchaser’s laboratory analysis. If Purchaser’s chemical analyses do not agree with Seller’s chemical analyses, Purchaser and Seller will attempt to harmonize the discrepancies, to determine the actual quality of the Coke delivered, and/or to mutually agree on appropriate adjustments. If Purchaser and Seller are unable to agree as to the chemical quality of Coke delivered, both Seller’s and Purchaser’s laboratories will analyze mutually agreed upon, certified standard samples of the chemical quality parameter in dispute. Both laboratories will adjust their laboratory equipment and/or procedures to conform to the value of the certified standard sample.

4.2 Adjustments to Specifications . Seller and Purchaser each acknowledge that several of the Coke Quality Specifications are dependent upon the coal blend used at the Coke Plant. From time to time, seller and Purchaser shall jointly develop the blend of coals to be used at the Coke Plant and shall mutually agree upon any required or resulting changes to the Coke Quality Specifications. Seller shall not alter the coal blend without the prior written approval of Purchaser, which will not be unreasonably withheld or delayed. Seller shall give Purchaser prompt written confirmation of any changes in the coal blend.

(d) Whenever any delivery does not conform to the Coke Quality Specifications, Seller shall immediately furnish Purchaser with an off-spec report in Purchaser’s-designated format, an example of which is attached hereto as Schedule 4.4(d) and incorporated herein by this reference, defining parameter, time, cause and corrective action.

(e) Seller will report analyses of Coke to Purchaser using Purchaser’s SPP formats, examples of which are attached hereto as Schedule 4.4(e) and incorporated herein by this reference, and will modify such formats as necessary.

(f) Seller and Purchaser will exchange samples for round robin testing between labs on a monthly basis.

4.5 Duality Committee . Seller shall accommodate quality audits and customer/supplier meetings with Purchaser, which will be held as often as required and at least quarterly, during which appointed representatives of Seller and Purchaser shall review performance to Coke Quality Specifications, changes to Coke Quality Specifications and coal blends.

13

4.6 Right to Reject . Purchaser, at its sole option, may reject any Coke that exceeds (higher or lower) one or more of the Reject Values specified in Schedule 4.1 attached hereto. Any such Coke will be considered unusable under the terms of this Agreement; provided , however, that:

(a) Purchaser shall be entitled to the benefit of the discount for Section 29 Tax Credits, if any, under Article V with respect to such rejected Coke to the extent such rejected Coke is sold by Seller to other than Purchaser and Seller replaces the rejected Coke with Coke not qualifying for the Credit Discount; and

(b) such rejected Coke will not be counted as satisfying Seller’s minimum delivery requirements under Section 3.1, unless such rejected Coke is subsequently delivered to, and accepted by, Purchaser.

4.7 Price Adjustments . All Coke which does not meet one or more Coke Quality Specifications, and which is not rejected by Purchaser pursuant to Section 4.6, will be subject to price adjustments based on analyses performed in accordance with Section 4.3 of this Coke Purchase Agreement, calculated according to the formulas set forth in Schedule 4.7 hereto.

4.8 Payment of Price Adjustments .

(a) Price Adjustments (Except Alkali and Phosphorus). Seller will generate and transmit to Purchaser a monthly quality summary within fifteen (15) working days after the end of each month. The quality summary will show by day (delivery) the Tons at *****% moisture, the current price and the delivery qualities for CSR, Moisture, Sulfur, Ash, Volatile Matter, Mean Size, Size *****, and Size *****, and Bulk Density. Any price adjustments associated with the individual deliveries will be calculated and a monthly total shown. Contemporaneously with the quality summary, Seller will invoice (debit or credit) Purchaser the amount of the price adjustments. Purchaser shall pay (debit or credit) any such quality price adjustments in immediately available funds on the first (1st) day of the month succeeding Seller’s transmittal of the quality summary and invoice to Purchaser.

(b) Price Adjustments (Alkali and Phosphorus). The Alkali and Phosphorus analysis will be performed on a weekly basis and reported to Purchaser on a monthly basis as provided herein.

Contemporaneously with the Off-

14

Spec Quality Report, Seller will invoice (debit or credit) Purchaser the amount of the related price adjustment. Purchaser shall pay (debit or credit) any such adjustment in immediately available funds on the first (1st) day of the month succeeding Seller’s transmittal of such Off-Spec Quality Report and invoice to Purchaser.

Seller shall not, without the prior consent of Purchaser, enter into any contracts with terms exceeding two (2) years for the supply of coals to be used in connection with the production of Coke at the Coke Plant. Such consent of Purchaser shall not be unreasonably withheld. Any of Seller’s contracts (or other purchases) with or from its Affiliates for coal used in the production of Coke shall be on terms no less favorable to Seller than such terms would be had such contract or purchase been with an unrelated third-party supplier of coal.

Coal to screened Coke yield standards as determined below will be used to convert coal price to coke cost:

(1) Seller and Purchaser agree to test the initial coal blend in the similar cokemaking facility owned by an Affiliate of, Seller to determine initial standards for coke quality and yield. This test will be run utilizing at least ***** (*****) coke ovens for a duration of at least seven (7) days; and

(2) As soon as practical, Seller will run control tests on the new ovens to determine final quality and yield standards for the initial blend. From time to time, Seller and Purchaser will run subsequent controlled tests and will mutually agree to change the standards as necessary. The testing procedure described in this subsection 5.1(a)(2) will be followed for any new coal blends.

15

(1) Budgeted Cost. No later than January 31, 1998, Seller shall establish a preliminary operating budget on a per Ton basis for the first year of the Initial Term, and such preliminary budget shall be revised during the third full month following Initial Full Production and such revised preliminary budget shall apply prospectively to periods following the third full month after Initial Full Production. No later than ninety (90) days prior to the end of each subsequent fiscal year, the Seller shall establish an annual budget on a per Ton basis for the Coke Plant, for the succeeding fiscal year (the “Annual Budget”), based on the following items:

(i) historical operations and maintenance history at similar cokemaking facilities operated by Affiliates of Seller; and

(ii) projected annual Coke production of 1.22 Million Tons at the Coke Plant.

(iii) labor expenses (which will not be inconsistent with market conditions and Purchaser’s labor relations); and

(iv) other conditions specific to the Coke Plant.

16

The preliminary budget, and each Annual Budget will set forth estimates with respect to operating costs, capital expenditures and other similar matters. The preliminary budget and each Annual Budget, as the same may be amended, shall become effective upon the occurrence of the earlier of: (A) the approval in writing by the Purchaser, or (B) the lapse of thirty (30) business days following notice of such preliminary budget and each Annual Budget to Purchaser. Seller shall use its good faith commercially reasonable efforts to operate the Cake Plant within the preliminary budget and each Annual Budget, as adopted.

If, within thirty (30) business days following notice by Seller to Purchaser of the preliminary budget and each Annual Budget, the Purchaser notifies Seller in writing of Purchaser’s disapproval of such preliminary budget and each proposed Annual Budget, the Parties shall, within ninety (90) days of Seller’s receipt of Purchaser’s written notice of disapproval, attempt to resolve their disagreements with respect to specific line item estimates set forth in the preliminary budget and each Annual Budget. Any disagreements that remain at the end of such ninety (90) day period shall be submitted to binding arbitration in accordance with the procedures established in Article XII hereof. Notwithstanding the foregoing, Seller shall continue to operate the Coke Plant, within the limitations set forth in the preliminary budget and each Annual Budget for which a disagreement between Purchaser and Seller exists (pending resolution by the Parties or binding arbitration, as the case may be) during any such period. In the case of an extraordinary event or expenditure which was not reasonably foreseeable by Seller, Purchaser and Seller agree to negotiate in good faith to amend the budget to give effect to increased operating costs resulting from such event or expenditures.

17

Except for a quarter during which a Fire/Explosion Period occurs and during which Purchaser has requested a reduction in Coke Plant production, Purchaser shall receive on a quarterly basis a credit with respect to the Contract Price equal to ***** are less than the preliminary budget and each Annual Budget estimate for the relevant period. Except for a quarter during which a Fire/Explosion Period occurs and during which Purchaser has requested a reduction in Coke Plant production, Purchaser shall be charged on a quarterly basis an amount equal to ***** exceed the preliminary budget and each Annual Budget estimate for the relevant period.

In any quarter during which a Fire/Explosion Period occurs and during which Purchaser has requested a reduction in Coke Plant Production, Purchaser will be charged for *****. Seller will use good faith reasonable commercial efforts to minimize operating costs incurred during such period; and

(2) Governmental Impositions. Operating Costs shall include all Governmental Impositions which Seller is not reasonably able to mitigate plus actual costs incurred by the Seller in the course of such mitigation.

Any increase in the Coke Plant’s operating cost per Ton as a result of the amendment or revision of any Coke Quality Specifications, will be paid by Purchaser as an adjustment to the Contract Price of the Coke sold under this Coke Purchase Agreement. Likewise, Purchaser will be entitled to an adjustment to the Contract Price of the Coke sold under this Coke Purchase Agreement in an amount equal to *****.

(c) Return on Capital Component: The projected cost per Ton will provide Seller with a ***** percent (*****%) after-tax return on the total Coke Plant capital cost (using internal rate of return method of calculation) (the “Total Coke Plant Capital Cost”) and will be fixed for the term of this Coke Purchase Agreement. The Return on Capital Component will be computed based on a ***** percent (*****%) combined federal/state tax rate. The Parties agree to negotiate in good faith an adjustment to the assumed tax rate and corresponding change in the Return on Capital Component if a tax in lieu, in whole or in part, of an income tax is imposed.

During the period covered by the preliminary budget the Return on Capital Component will be determined by Seller’s good faith estimate of Total Coke Plant Capital Cost. During the third full month of Initial Full Production the Final Return on Capital Component will be calculated using the Computer Model attached hereto as Schedule 5.1(c). The Tons of Coke sold in 1998 shall equal Seller’s good faith projection of 1998 Tons sold as projected in the third full month following Initial Full Production. In the event of any additional capital expenditures required by applicable law or regulation, the Computer Model will be used to recalculate a new rate of return (over the remaining economically useful life of the Coke Plant) taking into account such additional capital expenditures.

(d) [Intentionally Omitted].

(e) Discount for Section 29 Tax Credits:

(1) In the event that:

(i) Coke produced by the Coke Plant and sold to parties unrelated to Seller qualifies for a tax credit under Section 29 of the Code, and an investor (together with its successors and assigns, the “Initial Investor”) acquires an interest in Seller (such investment being the “Initial Investment”), the Contract Price per Ton of Coke delivered hereunder will be reduced during the Discount Period by the Credit Discount attributable to Coke produced by the Coke Plant from Qualified Ovens; provided, however, that the Credit Discount will not be attributable to Coke produced from Qualified Ovens in the Coke Plant in excess of 1.22 Million Tons during any twelve (12) month period commencing on or after Initial Full Production (pro-rated for shorter periods). Seller shall use its good faith efforts to obtain an Initial Investment and subsequent investments on commercially reasonable terms to Seller, GP and GP’s Affiliates for transactions involving facilities, of this type and which takes into account the availability to the Initial Investor of tax benefits (including, without limitation, credits available pursuant to Section 29 of the Code). The terms, conditions and pricing of such Initial Investment shall be structured by Seller, in its sole discretion, taking into account opportunities to minimize the Contract Price and amounts payable by Purchaser hereunder, Seller will consult with and keep Purchaser informed regarding the progress and proposed terms of the proposed Initial Investment and subsequent investments.

18

(2) “Discount Period” shall mean the period commencing on the date of the Initial Investment and ending on the Flip 1 Date.

(3) The “Credit Discount” shall mean the amount determined in accordance with Schedule 5.1(e) attached hereto and made a part hereof, but in no event exceeding ***** Dollars ($*****) per Ton. For the period commencing on the date of the Initial Investment and ending with the end of the fifth full calendar month following the later of Initial Full Production or the date of the Initial Investment, a tentative discount will equal ***** Dollars ($*****) per Ton, to be adjusted at the end of such period to reflect the actual Credit Discount, with an excess to be recovered by Seller by an increase in the Contract Price per Ton on the next issued invoice, plus interest at ***** basis points over the ninety (90) day U.S. Treasury bill, as quoted by the Wall Street Journal on the first business day of each month. Notwithstanding the foregoing, if the Initial Investment occurs on or before February 28, 1998, then during the period beginning on the date of the Initial Investment and ending on the earlier of June 30, 1998 or the date of Initial Full Production, the Credit Discount will be reduced by ***** Dollars ($*****) per Ton.

19

If the dollar value of Section 29 Tax Credits that is allocable to the Initial Investor will be less than the dollar value of Section 29 Tax Credits that would have been allocable to the Initial Investor if such a reduction had not occurred, whether as result of a Change of Law, Phase-Out, Disallowance, or otherwise, or if a Proposed Adjustment is made that if sustained would result in such a reduction of Credits, then the Credit Discount attributable to future deliveries of Coke hereunder shall be reduced by an amount equal to the Credit Discount determined without regard to this sentence multiplied by the Disallowance Percentage (the “Disallowed Discount”). To the extent that it is subsequently determined that such reduction (other than a reduction due to a Proposed Adjustment) in the Credit Discount is not applicable, Seller shall pay Purchaser an amount equal to the Disallowed Discount attributable to such determination, plus interest at a rate equal to the ***** plus ***** basis points.

Notwithstanding the foregoing, in the case of a Proposed Adjustment, an amount equal to the otherwise Disallowed Discount shall be deposited into the escrow account as described in Article IX. Upon the Final Determination regarding such Proposed Adjustment, Seller and Purchaser shall direct the Escrow Agent to disburse to Purchaser an amount attributable to the portion of the Proposed Adjustment not so sustained together with the Net Earnings thereon and the remainder to Seller together with the Net Earnings thereon.

The Credit Discount shall be reduced under this Section 5.1(e)(3) only in the case where the Initial Investor is protected from the loss or reduction in value of the Section 29 Tax Credits whether by means of a tax indemnity payment by GP, an extension of an Investor flip date or sharing phase or otherwise.

(4) On or before thirty days after the later of the date of the Initial Investment or the end of the third full month following Initial Full Production, Seller will compute the Credit Discount and provide Purchaser with written notice of the amount of the discount as well as a copy of the relevant calculation of the discount.

(5) In the event that:

(i) the Initial Investor or a new investor makes an investment in the Seller subsequent to the Initial Investment, whether by contribution or a purchase of a partnership interest; and

(ii) Coke produced by the Coke Plant and sold to parties unrelated to Seller continues to qualify for a credit under Section 29 of the Code,

Seller and Purchaser will negotiate a discount to the Contract Price per Ton in an amount and for a period consistent with the provisions of this subsection (e) and Schedule 5.1(e) hereto, as well as a related credit discount reduction and reimbursement provisions consistent with the provision of Section 5.1(e)(3) and (6) hereof.

During any period in which GP and Indiana Harbor Coke Corporation in the aggregate have an allocable share of Partnership revenue in excess of ***** percent (*****%), and an affiliated group filing a consolidated federal income tax return of which GP or Indiana Harbor Coke Corporation is a member, realizes an incremental cash tax benefit due to Section 29 Tax Credits attributable to the Coke Plant determined by comparing the consolidated cash tax liability due with and without its allocable share of the Section 29 Tax Credits attributable to the Coke Plant, Seller and Purchaser agree to negotiate in good faith a discount to the Contract Price reflecting an equal sharing of such incremental benefit, to be adjusted as such consolidated tax liability is adjusted by audit, appeal, and court decision and which will include a provision whereby the independent accountants for the affiliated group including such partners will certify to Purchaser, based upon the tax returns actually filed by such group, the actual incremental cash tax benefits received by such group, and will not provide for audits by such accountants of Purchaser.

20

(6)

(i) If there is any loss, Disallowance or reduction in the dollar value of Section 29 Tax Credits with respect to Coke production previously allocated to the Initial Investor, then Purchaser shall repay the Credit Discount to Seller in an amount equal to the Credit Discount claimed by Purchaser during the period to which the loss, Disallowance or reduction in value relates, multiplied by the Disallowance Percentage times the Tax Rate Adjustment Factor, plus interest computed on the amount of the Credit Discount to be refunded before adjustment by the Tax Rate Adjustment Factor, from the date that Purchaser received the Credit Discount to the date of repayment at the rate provided in (ii) below (the “Credit Discount Reimbursement”); provided, however, that Purchaser shall not be required to make any payment with respect to any Disallowance of Section 29 Tax Credits being contested by GP or the Initial Investor prior to a Final Determination of such proposed adjustment, provided, further that the Credit Discount Reimbursement shall be made only in the case where the Investor is protected from the loss, Disallowance or reduction in dollar value of Section 29 Tax Credits whether by means of a tax indemnity payment by GP, an extension of an Investor flip date or sharing phase or otherwise

(ii) In the event that GP is required to make a payment to the Initial Investor pursuant to the GP Indemnity Agreement relating to any loss, Disallowance or reduction in the dollar value of Section 29 Tax Credits, the applicable interest rate shall be the underpayment rate for large corporate underpayments as provided in section 6621(c) of the Code or its equivalent. If GP is not required to make such a payment to the Initial Investor and the loss, Disallowance or reduction in the dollar value of the Section 29 Tax Credits is equal to or greater than ***** percent (*****%) of the aggregate Section 29 Credits that would have been allocable to the Initial Investor without regard to such loss, Disallowance or reduction, the applicable interest rate shall be equal to the Investor’s Percentage Return in the Computer Model. In all other cases the applicable interest rate shall equal the ***** plus ***** basis points.

(iii) In the event that either the IRS proposes in writing an adjustment to any Partnership item of income, deduction or credit or GP receives notice from the

21

Initial Investor that it has received a notice in writing from the IRS of an adjustment, that, if agreed to by the Partnership or the Initial Investor, would result in a Credit Discount Reimbursement by Purchaser pursuant to this Agreement, Seller shall promptly notify Purchaser in writing of such proposed adjustment and of any action taken or proposed to be taken by the IRS with respect thereto. Purchaser will cooperate with GP and the Initial Investor in the contest of such item. In the event that the proposed adjustment is to be contested by the tax matters partner of the Partnership, Purchaser shall have the right to retain counsel, at its expense, to advise it with respect to the proposed adjustment, and GP shall keep Purchaser and its counsel informed as to the progress of such contest, give Purchaser and its counsel the opportunity to review and comment in advance on written submissions, filings and proposed settlements that relate to such proposed adjustment, and consider in good faith any suggestions made by Purchaser or its counsel. Likewise, in the event that the proposed adjustment is to be contested by the Investor, Purchaser shall have the right to retain counsel, at its expense, to advise it with respect to the proposed adjustment, and GP shall, to the extent not inconsistent with the rights GP has from the Investor, keep Purchaser and its counsel informed as to the progress of such contest, give Purchaser and its counsel the opportunity to review and comment to GP in advance on written submissions, filings and proposed settlements that relate to such proposed adjustment, and consider in good faith any suggestions made by Purchaser or its counsel. GP agrees to administratively contest any adjustment proposed in a partnership proceeding that, if sustained, would result in a Credit Discount Reimbursement and agrees to litigate such proposed disallowance (the particular court chosen being at the discretion of the GP) to the extent it cannot be administratively settled on reasonable terms, unless the GP receives a reasoned opinion of recognized outside tax counsel of Seller that there does not exist a reasonable possibility of success with respect to such matter. GP also agrees to appeal any adverse court decision unless Seller delivers to Purchaser a written reasoned opinion of recognized outside tax counsel of Seller to the effect that it is more likely than not that the appeal will not be successful. Purchaser shall reimburse Seller an amount equal to the Applicable Percentage multiplied by all reasonable third party costs and out-of-pocket expenses

22

that GP incurs in connection with the contest of such proposed adjustment by itself or by the Initial Investor including, without limitation, reasonable legal, witness and accounting fees and expenses, and in the case of proceedings before the Court of Federal Claims or Federal District Court, the amount of tax for which refund is claimed, any deposit related to such proceedings and any applicable interest, and in the case of appeal of a Tax Court decision, the cost of any bond filed pursuant to section 7485 of the Code or similar expense, payable within twenty (20) Business Days of invoice including a detailed description of the amount set forth in the invoice. , To the extent that such proceedings are resolved unfavorably to the IRS, Seller shall repay to Purchaser such amount of tax, deposit, bond, or similar item, together with any interest received with respect thereto. In no event shall Purchaser’s ultimate liability for interest under Section 5.1(e)(6) hereunder, but without regard to interest payable at the Overdue Rate, exceed that stated in Section 5.1(e)(6)(ii), with reconciliation and any payment due as a result thereof by Seller to Purchaser to be made within twenty (20) Business Days of the Final Determination of a proposed adjustment. Notwithstanding the foregoing, the GP may settle any disallowance or terminate any proceedings described in this paragraph in good faith, or consent thereto in good faith where the proposed adjustment is contested by the Initial Investor.

(iv) During any period in which Purchaser is in default of its obligations under subparagraph 5.1(e)(6)(i) above for more than thirty (30) days, Purchaser shall deposit the entire amount of any applicable Credit Discount to the escrow account established pursuant to the provisions of Article IX hereof, and the amount thereof shall be deposited with Escrow Agent pursuant to the Escrow established under Article IX hereof, until Purchaser ceases to be in default of such obligations under subparagraph 6(i), whereupon the Escrow Agent, upon direction by Seller and Purchaser, shall disburse such amount, together with the Net Earnings thereon to Purchaser.

(v) Payments required by Section 5.1(e)(6) shall be made by electronic bank transfer in immediately available funds in accordance with instructions provided by Seller, and shall be made within ten business days of Seller’s notice to Purchaser of its liability hereunder. Seller’s notice of payment due

23

under this subsection will include an explanation of the events resulting in Purchaser’s obligation hereunder and a reasonably detailed computation of the amount of such obligation. Late payments will be subject to interest at the Overdue Rate.

(f) Certain Revenues . As part of the monthly billing and invoicing procedures described herein in Article VII, during the term of this Coke Purchase Agreement, operating costs for any one month period will be credited with the amount of ***** multiplied by a percentage, the numerator of which will be ***** and the denominator of which will be *****.

Stockpiled Coke shall be rescreened and Purchaser and Seller shall cooperate in scheduling the shipment of Stockpiled Coke and production Coke in order to reduce the volume of Stockpiled Coke in an orderly manner throughout the term of this Coke Purchase Agreement. With respect to Stockpiled Coke, Purchaser will pay the Contract Price for such Coke as though the Coke had been delivered to Purchaser for that month. Purchaser shall reimburse Seller for the actual costs incurred by Seller in connection with the handling of such Coke. The Parties hereby acknowledge and expect that some amount of Stockpiled Coke will be lost as a matter of course, incidental to handling and transportation. Any such loss of Stockpiled Coke will be borne by the Purchaser. In reclaiming Stockpiled Coke, it is understood that there will be no guarantee of the specification regarding moisture.

ARTICLE IX

Escrow Account for Credit Discount

9.1 Establishment of Escrow Account . Pursuant to the terms and provisions of this Coke Purchase Agreement, Purchaser is entitled to receive from Seller the Credit Discount described more particularly in Section 5.1(e) hereof. In order to induce Seller to enter into this Coke Purchase Agreement and as further

26

security for the obligations of Purchaser under Section 5.1(e)(6) hereof, Purchaser hereby agrees that it will tender payment to Seller in the amounts invoiced pursuant to Article VII of this Coke Purchase Agreement, such invoiced amounts to be calculated using the methodology set forth in Article V giving effect to the provisions of Section 5.1(e) thereof regarding the Credit Discount.

During the first five (5) calendar years following the availability of any Credit Discount, Purchaser will deposit an amount equal to *****percent (*****%) of the applicable Credit Discount, if any, into an escrow account established and maintained with a financial institution that performs such services on a routine basis and is mutually acceptable to both Parties (the “Escrow Agent”). The Purchaser and Seller shall pay equally all costs and fees in regard to this escrow,

27

9.2 Purchaser’s Failure to Reimburse/Indemnify Seller . The Escrow Agent shall hold the escrowed funds in part as security for the performance by Purchaser of its obligations to pay Seller any Credit Discount Reimbursement or other sums pursuant to Section 5.1(e)(6).

In the event of any failure of Purchaser to perform with regard to its obligations to reimburse or otherwise indemnify Seller pursuant to Section 5.1(e)(6) hereof the Escrow Agent, upon receipt of appropriate written instructions pursuant to the Escrow Agreement, shall transfer to Seller the amount specified in such written instructions. To the extent that any escrow account balance is left following release of such amount to Seller, that balance shall remain in the escrow account. If the funds in the escrow account are insufficient to cover the Purchaser’s liability with regard to such reimbursement or indemnification obligation, then Purchaser will remain liable to Seller for any deficiency.

9.3 Release of Escrow . In the absence of any failure of Purchaser to perform with regard to its obligations to reimburse or otherwise indemnify Seller pursuant to Section 5.1(e)(6) hereof, and upon the first to occur of any of the following events, the escrow shall be released, and the Parties shall direct the Escrow Agent to transfer to the Purchaser, all the principal amounts previously deposited into the escrow account under Section 9.1 hereof, together with all Net Earnings accrued thereon from the time of deposit:

(b) issuance of an examination report for the Designated Year;

(c) executed Form 870-P (Agreement to Assessment and Collection of Deficiency and Tax for Partnership Adjustments) for the Designated Year;

(d) issuance of a Notice of Final Partnership Administrative Adjustment for the Designated Year; or

28

(e) expiration of the statute of limitations for assessments for the Partnership for the Designated Year.

Notwithstanding the foregoing, escrowed amounts will not be released to the extent that a Proposed Adjustment has been made for any Partnership taxable year that, if sustained, would result in a reduction in the dollar value of Section 29 Tax Credits that otherwise was allocated to the Initial Investor which reduction would give rise to a reduction in the amount of the Credit Discount or a deposit to the escrow account pursuant to Section 5.1(e) hereof.

To the extent that such a Proposed Adjustment is not sustained in a Final Determination, escrowed funds will be released provided that if there is an outstanding Proposed Adjustment for any Partnership taxable year that, if sustained, would result in a reduction in the dollar value of Section 29 Tax Credits that otherwise was allocated to the Initial Investor, escrowed funds will be retained in the escrow sufficient to cover Purchaser’s obligations hereunder with respect to such outstanding Proposed Adjustment.

9.4 Escrow Agreement . The Parties agree that any escrow account created in accordance with Section 9.1 hereof shall be established with, and managed by, the Escrow Agent, pursuant to an Escrow Agreement in form and content substantially similar to that attached hereto as Exhibit C.

10.5 Termination for Breach . Except as otherwise provided herein, upon the occurrence of any Event of Default, that remains uncured or uncorrected and unremedied for the respective periods described in Sections 10.1 through 10.4 hereof, this Coke Purchase Agreement may be terminated at the option of the non-defaulting Party immediately upon the giving of written notice of termination to the Party in default.

The Party so prevented from complying will give prompt written notice to the other Party of the nature and probable duration of such Force Majeure, and of the extent of its affects on such party’s performance hereunder; provided, however, that equipment failures of any kind caused primarily as a result of ordinary wear and tear or routine use over an extended period shall not be deemed an event of Force Majeure for purposes of this Coke Purchase Agreement.

Each Party will, in the event it experiences a force majeure event, make all reasonable efforts to remove such disability as soon as possible (except for labor disputes which will be solely within said Party’s discretion), and once the disability is removed this Coke Purchase Agreement will be reinstated. During any period of Force Majeure related to Purchaser’s No. 7 Blast Furnace at its Indiana Harbor Works facility,

31

Purchaser will use Coke from Seller’s Coke Plant to fulfill Purchaser’s Coke requirements to supply its other Indiana Harbor Works blast furnaces, before using any other source of coke. During any period of Force Majeure relating to Seller’s Coke Plant, all production of Coke from the Coke Plant, up to Purchaser’s maximum take or pay obligation, will be supplied to Purchaser before any Coke from Seller’s Coke Plant may be sold to third parties.

11.2 Special Excuse for Nonperformance by Purchaser . Purchaser’s obligation to purchase the Coke produced by the Coke Plant will be further qualified by the need, during the term of this Coke Purchase Agreement, to reline Purchaser’s No. 7 Blast Furnace. In order to be entitled to claim the benefit of this Section 11.2, Purchaser must furnish written notice to Seller at least one (1) year in advance of any contemplated relining of Purchaser’s Blast Furnace No. 7, and such written notice must specify the probable duration of such relining. During the period necessary to complete the relining of Purchaser’s Blast Furnace No. 7, it being understood that such period shall in no event exceed five (5) months, Purchaser will use its best efforts to utilize the Coke produced by the Coke Plant in Purchaser’s other blast furnaces. At least two weeks prior to the completion of any relining of Purchaser’s No. 7 Blast Furnace, Purchaser shall notify Seller in writing as to Purchaser’s intended date of restart of operations at its No. 7 Blast Furnace, so that this Coke Purchase Agreement may be reinstated at the appropriate time. Purchaser will promptly inform Seller in writing in the event of any changes reasonably likely to delay Purchaser’s intended date of restart of operations at its No. 7 Blast Furnace by more than five (5) days.

11.3 Major Fire or Explosion . Immediately following any major fire or explosion that Purchaser reasonably believes will render it wholly incapable of receiving, accepting and/or utilizing Coke at Purchaser’s No. 7 Blast Furnace for a period of at least thirty (30) days duration, Purchaser will furnish Seller with a written notice containing a description of such fire or explosion, together with Purchaser’s reasonable good faith estimate of the duration of its inability to accept or utilize Coke at Purchaser’s No. 7 Blast Furnace. In such written notice to Seller, Purchaser may elect to reduce the Minimum Coke Purchase Requirement by up to one-third (1/3) during the period that Purchaser is wholly incapable of receiving, accepting and/or utilizing Coke at Purchaser’s No. 7 Blast Furnace and the additional period referred to in Section 11.3(e) (these two periods together being the “Fire/Explosion Period”). During the Fire/Explosion Period:

(a) Production of Coke from the Coke Plant shall be set at a level to include:

(1) the reduced Minimum Purchase Requirement requested by Purchaser pursuant to this Section 11.3;

(2) Seller’s pre-existing sales contract amounts;

(3) additional amounts requested by Seller , to the extent such additional amounts are approved by Purchaser;

(b) Purchaser will accept delivery of the reduced Tonnages of Coke it has agreed to take during the Fire/Explosion Period and Purchaser may elect to have Seller resell such purchased Coke to others on Purchaser’s behalf in accordance with Section 3.1(e) of this Agreement;

(c) Purchaser will pay to Seller an amount equal to the product of the Return on Capital Component of the Contract Price, multiplied by the difference between: the Minimum Coke Purchase Requirement (calculated on a daily basis and unadjusted by this Section l.3) and the actual level of Coke Plant production during the Fire/Explosion Period;

(d) Purchaser will continue to receive any Credit Discount available with regard to the Tonnages of Coke actually purchased and accepted by Purchaser under this Section 11.3; and

(e) Purchaser shall notify Seller in writing as to Purchaser’s intended date of restart of operations at its No. 7 Blast Furnace and, at Purchaser’s election, Purchaser may continue to take Coke at the reduced level for so long as is necessary for Purchaser to utilize stockpiles of Coke accumulated solely as a result of any major fire or explosion described by this Section 11.3. During any such period of continued reduced taking of Coke by Purchaser, Seller will continue to collect from Purchaser the amount described by Section 11.3(c).
