NOW THEREFORE, in consideration of the promises and the mutual agreements herein contained and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereto, intending to be legally bound, agree as follows:

1. Definitions. Capitalized terms used in this Amendment that are not otherwise defined herein shall have the meanings set forth in the Coke Purchase Agreement.

2. Amendment Effective Date. The effective date of this Amendment shall be January 1, 2011 (the “Amendment Effective Date”).

3. Amendments.

(a) Effective on and as of the Amendment Effective Date, Section 3.1(c)(v) is hereby deleted in its entirety and replaced by the following:

(v) The Forecasted O&M Component for each Contract Year will be determined in accordance with the following formula:

Forecasted O&M Component (Coke Plants) = [Forecast O&M Expenses (or if such Forecast is subject to a dispute, the Presumed O&M Expenses, until such time as the dispute is resolved) in respect of the Coke Plants (excluding the Forecast O&M Expenses associated with the Cogeneration Plant) set forth in the approved Forecast for the applicable

Contract Year * *****% and then divided by Purchaser’s Targeted Coke Production in respect of the Coal Blend(s) to be utilized during such Contract Year] + [Forecast O&M Expenses (or if such Forecast is subject to a dispute, the Presumed O&M Expenses, until such time as the dispute is resolved) associated with the Cogeneration Plant set forth in the approved Forecast for the applicable Contract Year ÷ Purchaser’s Targeted Coke Production in respect of the Coal Blend(s) to be utilized during such Contract Year].

(b) Effective on and as of the Amendment Effective Date, Section 3.1(c)(vi) is hereby deleted in its entirety and replaced by the following:

(vi) Seller shall endeavor in good faith to operate and maintain the Coke Plants in accordance with the Forecasted O&M Component for the applicable Contract Year in accordance with Prudent Operating and Maintenance Practices. Subject to the foregoing, within thirty (30) days following the conclusion of each Contract Year, Seller will submit to Purchaser a Written report that summarizes the actual O&M Component for such Contract Year (the “Actual O&M Component”) as determined in accordance with the following formula:

Actual O&M Component = budgeted O&M expenses in respect of the Coke Plants (excluding O&M Expenses associated with the Cogeneration Plant) for the applicable Contract Year * *****%, plus or minus *****% of the variance between actual O&M expenses and budgeted O&M expenses and then divided by the actual Coke Tonnage delivered to Purchaser from the Coke Plants during such Contract Year (including Nonconforming Coke Tonnage rejected by Purchaser) + [budgeted O&M expenses associated with the Cogeneration Plant for the applicable Contract Year, plus or minus *****% of the variance between the actual O&M and the budgeted O&M expenses ÷ the actual Coke Tonnage delivered to Purchaser from the Coke Plants during such Contract Year (including Nonconforming Coke Tonnage rejected by Purchaser)]

Where applicable, but subject to Article VII, Purchaser shall pay Seller an amount equal to the product of (i) any positive difference between (y) the actual O&M Expenses in respect of the Coke Plants and Cogeneration Plant for the applicable Contract Year and (z) the Forecast O&M Expenses in respect of the Coke Plants and Cogeneration Plant as set forth in the Forecast for such Contract Year, converted to a per ton bases and multiplied by (ii) actual Coke production delivered to Purchaser during such Contract Year (excluding, in each case, Nonconforming Coke Tonnage rejected by Purchaser). Where applicable, but subject to Article VII, Seller shall credit Purchaser an amount equal to the product of (i) any negative difference between the (y) Actual O&M Expenses in respect of the Coke Plants and Cogeneration Plant for the applicable Contract Year and (z) Forecasted O&M Expenses in respect of the Coke Plants and Cogeneration Plant for such Contract Year, converted to a per ton bases and multiplied by (ii) actual Coke production delivered to Purchaser during such Contract Year; provided, however, that in no event shall the actual Coke production amount utilized in the denominators to the foregoing formulas be less than *****% of the Targeted Coke Production for the applicable Contract Year; provided, further, that such *****% limitation shall not apply to any Month during such Contract Year when a Production Turndown is in effect. Such payment or credit shall, as applicable, be added to or deducted from the amounts otherwise payable in accordance with the invoice in respect of the Month during which such credit or payment is determined, and shall be subject to reasonable verification by Purchaser. For clarity, set forth on Schedule 3.1(c)(vi) are examples of this calculation showing both a payment by Purchaser and a credit to Purchaser.

(c) Effective on and as of the Amendment Effective Date, Section 3.1(d)(vi) is hereby deleted in its entirety and replaced by the following:

(vi) The Guaranteed Coke Yield Percentage is determined in accordance with the following formula:

Blast furnace coke “dry” yield equals *****% less the sum of the percentage of dry basis volatile matter in the Coal Blend (using the weighted average actual volatile matter in the Coal Blend determined based upon daily coal samples) plus a three percent (*****%) allowance for net operating losses in the coking process plus a five percent (*****%) allowance for Breeze; provided, however, if the Weighted Average actual moisture content of such Coal Blend Tonnage exceeds *****%, then for each increment of *****% in excess of *****%, such *****% allowance shall be correspondingly increased by *****%. By way of example, if the actual Weighted Average moisture content of the Coal Blend is *****%, then the corresponding allowance for net operating losses in the coking process would be *****%.
