 AMENDED AND RESTATED COKE PURCHASE AGREEMENT 

THIS AMENDED AND RESTATED COKE PURCHASE AGREEMENT dated as of September 1, 2009 (the “Effective Date”), is made by and
between Middletown Coke Company, Inc., a Delaware corporation (“Seller”) and AK Steel Corporation, a Delaware Corporation (“Purchaser”). This Agreement is a companion accord to the Amended and Restated Energy Sales Agreement
between Seller and Purchaser dated concurrently with this Agreement (the “Related Energy Sales Agreement”) and the Agreement Regarding Expedited Equipment Purchases between Seller and Purchaser dated as of March 4, 2008, as amended
(the “Equipment Agreement”). 
 For good and valuable consideration, including the Related Coke Purchase Agreement and
the Equipment Agreement, the Parties, intending to be legally bound, agree as follows: 
 ARTICLE I 

DEFINITIONS; ACKNOWLEDGEMENT; BASIC OBLIGATIONS OF THE PARTIES 

1.1 Definitions. The definitions of certain capitalized terms used in this Agreement are contained in the attached Appendix A.

 1.2 The Plant. Pursuant to this Agreement, the Related Energy Sales Agreement and the Equipment Agreement, Seller is
to construct (subject to the Contingencies) (i) a metallurgical coke making plant consisting of one hundred (100) heat recovery ovens organized in three oven batteries, (ii) an associated cogeneration plant (the “Cogeneration
Plant”) that converts steam produced at such coke plant into electrical energy, and (iii) related facilities and equipment (collectively, the “Plant”), all to be located on certain real property to be acquired by Seller that is
contiguous with Purchaser’s Middletown Plant (the “Property”). The Plant is to be owned and operated by Seller based upon heat recovery technology that is proprietary to Seller and its Affiliates. 

1.3 Basic Obligations of the Parties. Subject to the terms, conditions and requirements of this Agreement: 

(a) Delivery and Acceptance Obligations. 
 (i) During the Initial Operating Period, Seller shall deliver to Purchaser and Purchaser shall accept all Coke Tonnage, except for Nonconforming Coke Tonnage that is rejected by Purchaser pursuant to
Section 5.1(b)(iii). Seller will also provide to Purchaser, on the first business day of each Week, a nonbinding projection of (x) the duration of the Initial Operating Period, (y) Coke production for such Week, and (z) Coke
production for each subsequent Week remaining in the Initial Operating Period. 
 (ii) Following the Initial
Operating Period and throughout the balance of the Term, Seller shall deliver to Purchaser and Purchaser shall accept all Coke Tonnage (subject to Seller’s obligations in respect of the Coke Supply Obligation), except for Nonconforming Coke
Tonnage that is rejected by Purchaser pursuant to Section 5.1(b)(v). 

  
 1 








 (b) Pricing and Payment. During the Term, the purchase price payable by Purchaser to
Seller in respect of Coke Tonnage is the Coke Price (except for Nonconforming Coke Tonnage that is rejected by Purchaser pursuant to Section 5.1(b)(v)), and for Nonconforming Coke Tonnage that is not rejected by Purchaser is the applicable
price set forth in Section 5.1(b)(v). Such amounts shall be payable in accordance with Section 3.3. 
 (c)
Integrated Transaction. The Parties acknowledge that (i) they are entering into this Agreement, the Related Energy Sales Agreement and the Equipment Agreement as a single integrated transaction, (ii) they would not enter into the
Related Energy Sales Agreement without also entering into this Agreement, and (iii) this Agreement and the Related Energy Sales Agreement are inextricably linked technically and economically, that neither would be feasible without the other,
and they constitute a single integrated transaction and agreement. 
 1.4 Seller’s Notice and Reporting Obligations.

 (a) Schedule and Progress Reports. The Parties acknowledge that Purchaser will be required to prudently manage third
party coke purchases and coke inventories in respect of the Middletown Plant pending the development of the Plant (and the date that the Plant demonstrates the commercial capability of producing Coke at its full production level). Accordingly, at
least ten (10) days following the satisfaction of each of the Contingencies (but subject to such Contingencies), Seller shall deliver to Purchaser a construction schedule that details the various phases of such work, including corresponding
milestone dates for major systems and equipment, and the substantial completion date prior to the commencement of the construction of physical improvements in respect of the Plant (the “Work”). Within three (3) business days following
the commencement of the construction of such Work, Seller will provide Purchaser with Written notice thereof. Seller will provide Written progress reports once per month, which shall include all material schedule updates and revisions in respect of
such Work, through the commencement of the Initial Operating Period. Such reports will be consistent with Seller’s internal reports in respect of the completion and status of applicable schedule milestones. 

(b) Weekly Meetings. In addition to the provision by Seller to Purchaser of the reports described in Section 1.4(a), Seller
and Purchaser shall schedule weekly on-site meetings whereby Seller or its designee shall informally report to Purchaser the status and progress of the Work, including (as applicable) any material revisions to the construction schedule in respect of
milestone dates and the substantial completion date for such Work. Seller shall also permit Purchaser to inspect the Plant construction site for the purpose of evaluating the progress of the Work; provided, however, all such site inspections shall
be subject to the supervision of Seller and its designee, and shall be conducted in a manner consistent with Seller’s safety policies and guidelines. 
 (c) Recovery Plans. In the event of any schedule delays in respect of construction milestones or the substantial completion date, Purchaser shall be advised of (as applicable) any recovery plans
and shall be invited to attend meetings between Seller and its suppliers and contractors in respect thereof; provided, however, neither Seller, its suppliers nor its contractors shall be obligated to implement any recommendations of Purchaser in
respect of any such recovery plans. 

  
 2 








 1.5 Guarantee of Seller’s Obligations. The obligations of Seller under this
Agreement shall be guaranteed by SunCoke and Sun Coal & Coke Company, a Delaware corporation, pursuant to a guaranty in the form of Schedule 1.5 that Seller shall cause to be executed and delivered to Purchaser at the time of the execution
and delivery of this Agreement. 
 1.6 Transfer Restrictions. Purchaser shall not transfer or otherwise dispose of the
Middletown Plant without the prior Written consent of Seller. If Purchaser wishes to sell, lease, transfer or otherwise dispose of all or a substantial portion of its assets (other than the Middletown Plant), whether in a single transaction or
series of transactions, then it shall cause to be delivered to Seller at least forty-five (45) days prior to such sale, lease, transfer or other disposition (i) a Written notice of such sale, lease, transfer or other disposition,
(ii) a guaranty executed by AK Steel Holding Corporation, a Delaware corporation (“Holding”) in the form of Schedule 1.6, and (iii) an opinion of independent legal counsel to Holding, which legal counsel shall be reasonably
satisfactory to Seller and which opinion shall be in form and substance reasonably satisfactory to Seller, to the effect that such guaranty is the legal, valid and binding obligation of, and enforceable against Holding, subject to customary
exceptions. The Parties acknowledge that in the event any of the foregoing obligations are breached by Purchaser or Holding, Seller shall be entitled to both interim and permanent injunctive relief in respect of such obligations, including (as
applicable) injunctive relief and specific enforcement against Purchaser and Holding. Notwithstanding the foregoing, Purchaser shall not be restricted from creating or permitting to exist (and the foregoing provisions shall not apply to) any lien,
security interest or other encumbrance on any of its assets. 
 1.7 Holding Guaranty. Following the expiration,
cancellation or termination of the Indenture, Holding shall promptly (i) notify Seller of such circumstance in Writing, and (ii) execute and deliver to Seller a guaranty of Holding in favor of Seller in the form of Schedule 1.6. Such
guaranty obligation shall be specifically enforceable by Seller against Holding. 
 ARTICLE II 

TERM 
 2.1 Term. The term of this Agreement (“Term”) shall commence on the Effective Date and, subject to earlier termination in accordance with this Agreement, shall continue in effect for
twenty (20) Contract Years. Upon the conclusion of such twenty (20) Contract Years, this Agreement shall automatically renew for two (2) successive five (5) year terms each unless notice of termination is given by either Party at
least one (1) year prior to the end of the Term. 
 ARTICLE III 

COKE PRICE AND PAYMENT TERMS 
 3.1 Coke Price. 
 (a) Components. Subject to Section 3.4:

 (i) During the Initial Operating Period, and for the balance of the year (namely, through December 31st)
during which the Initial Operating Period expires (the “Initial Year”), the Coke Price is the sum of (x) the Adjusted Fixed 

  
 3 








 
Price Component, (y) the Initial O&M Component, plus (z) the Coal Cost Component; and 
 (ii) During each Contract Year (following such Initial Year), the Coke Price is the sum of (A) the Adjusted Fixed Price Component, (B) subject to Section 3.1(c)(vi), the Forecasted O&M
Component, and (C) the Coal Cost Component. 
 (b) Adjusted Fixed Price Component. 

(i) The Fixed Price Component is $***** per Ton of Coke. 

(ii) The Parties acknowledge that Coke production depends upon the moisture content of each Coal Blend. Accordingly, the
Fixed Price Component shall be adjusted (increased or decreased) based upon the Weighted Average moisture content of the Coals comprising each Coal Blend for the applicable Month. Accordingly, if the actual Weighted Average moisture content of such
Coal Blend Tonnage exceeds *****%, then for each *****% increment thereof in excess of *****%, the Fixed Price Component shall be correspondingly increased by *****%. Conversely, if the actual Weighted Average moisture content of such Coal Blend
Tonnage is less than *****%, then for each *****% increment thereof less than *****%, the Fixed Price Component shall be correspondingly reduced by *****%. By way of example, if the actual Weighted Average moisture content of the Coal Blend is
*****%, then such adjusted Fixed Price Component (the “Adjusted Fixed Price Component”) is $***** (namely, the sum of the (i) Fixed Price Component plus the (ii) product of the Fixed Price Component multiplied by *****%).
Conversely, and by way of example, if the actual Weighted Average moisture content of the Coal Blend is *****%, then such Adjusted Fixed Price Component is $***** (namely, the sum of (i) Fixed Price Component minus the (ii) product of the
Fixed Price Component multiplied by *****%). 
 (c) Initial O&M Component, Forecasted O&M Component, Actual O&M
Component and Annual True-Up. 
 (i) During the Initial Year, the O&M Component is $***** per ton of Coke
(the “Initial O&M Component”). 
 (ii) Following such Initial Year, and at least sixty
(60) days prior to the commencement of each Contract Year, Seller will prepare a good faith forecast (the “Forecast”) that sets forth in reasonable detail its good faith estimate of the O&M Expenses in respect of the Plant and the
for the next ensuing Contract Year. For the avoidance of doubt, such O&M Expenses include operating and maintenance costs in respect of the Cogeneration Plant notwithstanding the circumstance that payments in respect of electrical energy
produced by such Cogeneration Plant are made pursuant to the Related Energy Sales Agreement. 

  
 4 








 (iii) Without duplication or double-counting in respect of O&M Expenses,
such Forecast shall be based upon (i) subject to any applicable confidentiality restrictions in respect of other customers of Seller’s Affiliates, typical historic operations and maintenance history at other domestic coke making facilities
that utilize SunCoke’s proprietary heat recovery coke making technology as such history applies to the Plant; (ii) historic operations and maintenance history at the Plant; (iii) subject to Article VII, compliance with Governmental
Requirements in respect of the Plant, including Government Mandated Additional Expenses; (iv) property taxes in respect of the Plant; (v) Targeted Coke Production in respect of the Coal Blend(s) to be utilized during such Contract Year;
(vi) labor expenses in respect of the Plant; (vii) Prudent Operating and Maintenance Practices; (viii) the reasonable cost of all premiums or, as applicable, allocations, in respect of required and commercially reasonable insurance
coverages for the Plant, Plant operations, and employees of Seller (provided such allocations or premiums constitute O&M Expenses), and (ix) other reasonable conditions specific to the Plant and Seller’s performance hereunder (the
“Guidelines”); provided, however, but subject to Section 7.1(c), such other reasonable conditions shall not include fines or penalties in respect of violations of Governmental Requirements including Governmental Requirements
pertaining to the environment, and employee health and safety. Such Forecast shall be delivered to the Purchaser for approval by it, which approval shall not be unreasonably withheld, conditioned or delayed. 

(iv) Within fifteen (15) days following Seller’s delivery of each such Forecast to Purchaser, Seller and
Purchaser shall confer in good faith for the purpose of reviewing and approving such Forecast. If, within thirty (30) days thereafter, the Parties do not agree upon such Forecast, then Purchaser shall promptly deliver to Seller (no later than
ten (10) days following the expiration of such thirty (30) day period) Written notice of its disapproval of such Forecast that sets forth the specific grounds therefor including any alleged inconsistency thereof with the Guidelines. The
Parties may thereafter submit such dispute to arbitration in accordance with Section 9.2; provided, however, pending such resolution, (i) the O&M Expenses in respect of the preceding Contract Year, as adjusted in accordance with the
Index Formula (the “Presumed O&M Expenses”), shall be the basis for the O&M Expenses for the period during which such dispute is pending (except for the first Contract Year, for which the Presumed O&M Expenses in respect of
such Contract Year pending that resolution shall be the Initial O&M Component as adjusted in accordance with the Index Formula), and (ii) if, following any such arbitration, it is determined that the allowable O&M Expenses are greater
or less than the Presumed O&M Expenses, then Purchaser or, as applicable, Seller shall pay to the prevailing Party the product of the difference between (i) the (y) Forecasted O&M Component based upon the Presumed O&M Expenses
for the applicable Contract Year or, as applicable, in respect of the Initial Year, and (z) the Forecasted O&M Component based upon the O&M Expenses approved pursuant to such arbitration, multiplied by (ii) the Coke Tonnage sold by
Seller to Purchaser based upon such Presumed O&M Expenses, plus interest thereon accrued thereon at the Interest Rate. Such 

  
 5 








 
payment shall be, as applicable, added to or credited against the amount otherwise payable by Purchaser to Seller in accordance with the Monthly invoice immediately following any such award.

 (v) The Forecasted O&M Component for each Contract Year will be determined in accordance with the
following formula: 
 Forecasted O&M Component = [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 Plant set forth in the approved Forecast for the applicable Contract Year ÷ Targeted Coke Production in respect of the Coal Blend(s) to be utilized
during such Contract Year] 
 (vi) Seller shall endeavor in good faith to operate and maintain the Plant 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 = actual O&M Expenses in respect of the Plant for the applicable Contract Year ÷ actual Coke
Tonnage produced at the Plant 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 *****% of the product of (i) any positive
difference between the (y) Actual O&M Component for the applicable Contract Year and (z) Forecasted O&M Component as set forth in the Forecast for such Contract Year, 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 *****% of any (i) negative
difference between the (y) Actual O&M Component the applicable Contract Year and (z) Forecasted O&M Component for such Contract Year, multiplied by (ii) actual Coke production delivered to Purchaser during such Contract Year;
provided, however, 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. 

  
 6 








 (d) Coal Cost Component. 

(i) Coal Costs are all costs, expenses and expenditures, including Taxes, related to sampling, testing, selecting,
purchasing, storing, handling of Coals, and in respect of transporting, and delivering the Coals to the Plant, but excluding overhead or administrative costs of Seller or its Affiliates in respect thereof. Unless otherwise approved by Purchaser,
each Coal comprising the selected Coal Blend shall be purchased by Seller for a commercially reasonable price, and in accordance with commercially reasonable standards, terms and conditions based upon thirty (30) day payment terms. Coal Costs
do not include penalties, assessments and damages recovered by Seller in respect of Coal contracts with Coal suppliers to the extent such penalties, assessments and/or damages result in Coke Price reductions as set forth in Schedule 5.1 or any
successor schedule (in which case such penalties, assessments and/or damages shall be for the account of Seller); provided, however, if such penalties, assessments and/or damages exceed such Coke Price reductions, or such penalties, assessments
and/or damages do not result in a Coke Price reduction, then any such excess amount(s) or such penalties, assessments and/or damages not resulting in a Coke Price reduction will be deducted from the Coal Costs. 

(ii) The Coal Cost Component is (i) the actual Monthly Weighted Average Coal Costs, divided by (ii) the product
of (y) the Moisture Adjusted Coal Blend Tonnage charged to the coke ovens at the Plant set forth in each applicable invoice, taking into account Coal Handling Losses, and (z) the Guaranteed Coke Yield Percentage. 

(iii) The Moisture Adjusted Coal Blend Tonnage is the Weighted Average thereof for each applicable Month, and accounts for
Coal Blend moisture on a fixed *****% basis to be determined in accordance with the following formula: 
 Moisture Adjusted
Coal Blend Tonnage = actual Coal Blend Tonnage (as determined in accordance with Section 3.1(d)(v)) x [(1 – the actual moisture content of such Coal Blend Tonnage) ÷*****]. 

Such actual moisture shall be determined based on sampling of the actual Coal Blend Tonnage immediately prior to coking thereof, and the
testing and analysis on a composite basis, all of which shall be performed in accordance with ASTM Standards. 

(iv) Coal Handling Losses shall be fixed at *****%, and shall be accounted in accordance with the following formula:

 Moisture Adjusted Coal Blend Tonnage for each Coke shipment x 

***** 

  
 7 








 (v) Seller’s static scale shall weigh Coal Blend Tonnages immediately
prior to coking. Such scale shall have an accuracy of not less than plus or minus (+/-) 0.25%, and shall be calibrated in accordance with the manufacturer’s instructions at Seller’s sole cost and expense. Absent Manifest Error, such weight
determinations shall be conclusive and binding on the Parties. 
 (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 (described as the “typical” dry basis volatile matter in the Coal contracts pertaining to the Coal Blend) plus a *****% allowance for net operating losses in the
coking process; 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 *****%. 

Seller will re-determine the Guaranteed Coke Yield Percentage whenever the proportionate share of Coals within any Coal Blend is increased
or decreased by *****% or more. 
 (e) Determination of Coke Tonnage. All Coke Tonnage shall be weighed by belt scales
operated by Seller. Such scales shall have an accuracy of not less than 0.25%, and shall be maintained and calibrated in accordance with the manufacturer’s instructions, the cost of which calibration shall be an O&M Expense. Absent Manifest
Error, such weight determinations shall be conclusive and binding on the Parties. All Coke Tonnage shall be adjusted to a *****% moisture content in accordance with the following formula: 

Tons Sold        =        Total Tons x
(1 – actual percentage moisture content) 

            ***** 

The actual moisture percentage content of Coke shall be determined in accordance with Section 5.1. 

3.2 Section 45 Credits. 
 (a) In General. Provided Purchaser is not in default of this Agreement, if any Coke qualifies for a credit under the Section 45 of the Internal Revenue Code of 1986, or any similar or
successor provision (“Section 45 Credits”) during any year during which Coke is produced during the Term, then Seller shall provide Purchaser with a credit in respect of Coke Tonnage sold by Seller to Purchaser during such year, provided
that in any Production Turndown Period the credit provided to Purchaser shall be reduced proportionately based on the Coke Purchase Shortfall. 

  
 8 








 (b) Sunoco Realized Value. Where Sunoco or its Affiliates are the sole investors in
Seller, such credit shall be equal to *****% of the Sunoco Realized Value of such Section 45 Credits. Such Sunoco Realized Value is the pre-tax value realized by Sunoco in respect of such Section 45 Credits, which shall be determined by
dividing the amount of such Section 45 Credits by one (1) minus the sum of (x), where (x) is the highest marginal federal income tax rate applicable to corporations, minus, in respect of section 199 of the Internal Revenue Code of
1986, (i) two (2) percentage points in respect of year 2009, or (ii) three percentage points for each subsequent year during which such Section 45 Credits may be available; provided, however, such Sunoco Realized Value shall also
take into account any change in law, phase out, the ability of Sunoco to utilize the Section 45 Credits, or other circumstances relevant to such Sunoco Realized Value determination. The ability of Sunoco to utilize such Section 45 Credits
shall be determined by comparing Sunoco’s current federal consolidated tax liability with and without the Section 45 Credits attributable to Coke sales to Purchaser in respect of each such year. The determination of such Sunoco Realized
Value in respect of each year during which Section 45 Credits may be available shall be made on or before October 1st of the subsequent year and shall be credited on the invoice for such Month; provided, however, that if there is any
change in law that repeals or reduces the amount of the section 199 deduction of the Code, or that limits the benefit or availability of such deduction, in either case with respect to income arising from the sale of Coke under this Agreement, then
the amounts subtracted pursuant to subparts (i) and (ii) of this Section 3.2(b) shall be reduced to reflect such change. 
 (c) Other Realized Value. Where Sunoco or its Affiliates, and any third party or parties (the “Third Party Investor(s)”), are the investors in Seller, such credit shall be equal to *****%
of the Other Realized Value of such Section 45 Credits. Such Other Realized Value is the product of (i) the percentage interest of Sunoco or its Affiliates and such Third Party Investor(s) in respect of the revenue derived from the sale of
Coke multiplied by, as applicable, (ii) the pre-tax value realized by (y) Sunoco in respect of such Section 45 Credits (as determined in accordance with Section 3.2(b)) and (z) the Third Party Investor(s) as determined in a
manner consistent with Section 3.2(b); provided, however, (i) such Other Realized Value in respect of any year shall not be less than the Sunoco Realized Value for such year had such Third Party Investor(s) not been investors in Seller;
and (ii) such Other Realized Value shall also take into account any change in law, phase out, the ability of Sunoco or, as applicable, the Third Party Investor(s) to utilize the Section 45 Credits, or other circumstances relevant to such
Other Realized Value determination. The determination of such Other Realized Value in respect of each year during which Section 45 Credits may be available shall be made on or before the last Month of subsequent year and shall be credited on
the invoice for such Month. 
 (d) Increases or Reductions. If the Sunoco Realized Value or Other Realized Value of any
Section 45 Credits on Coke sales to Purchaser is thereafter reduced by the carry back of a net operating loss in respect of an amended return, disallowance of all or a portion of the Section 45 Credits, or the inability of Sunoco or (as
applicable) the Third Party Investor(s) to utilize the Section 45 Credits after final resolution of an IRS audit, then Purchaser shall pay to Seller, within thirty (30) days following Seller’s Written notification to Purchaser of such
reduction, an amount equal to (i) *****% of the Sunoco Realized Value and (as applicable) the Other Realized Value that would otherwise would have been realized but for such reduction plus *****% of any fines and/or penalties arising from such
disallowance, plus (ii) interest thereon, 

  
 9 








 
computed from the date of filing of the consolidated income tax return of Sunoco or, as applicable, Third Party Investor(s) through the date on which such amount is paid by Purchaser to Seller.
Such interest shall be equal to the additional interest owed by Sunoco or (as applicable) Third Party Investor(s), or the reduction in interest due to Sunoco or (as applicable) Third Party Investor(s) if Sunoco or (as applicable) Third Party
Investor(s) is in an overpayment position, determined by computing Sunoco’s or (as applicable) Third Party Investor(s)’ federal income tax liability for the year with and without *****% of the disallowed or reduced Section 45 credits.
If the Sunoco Realized Value and (as applicable) the Other Realized Value of any Section 45 Credits from Coke sales to Purchaser is thereafter increased as a result of the ability of Sunoco or (as applicable) Third Party Investor(s) to utilize
the carryover of any unused Section 45 Credits in later taxable years, or the ability of Sunoco or (as applicable) Third Party Investor(s) to utilize additional Section 45 Credits after final resolution of an IRS audit, then Seller will
credit Purchaser with an amount equal to (i) *****% of the Sunoco Realized Value and (as applicable) the Other Realized Value in respect of such increase, plus (ii) interest thereon at the overpayment rate of section 6621 of the Code or
the successor provision, computed from the date of filing of the consolidated income tax return of Sunoco or (as applicable) Third Party Investor(s) for the year in which the credit is utilized through the date on which such amount is credited by
Seller to Purchaser. Any such credit shall be applied to the invoice for such Month during which such Section 45 Credits are utilized. 
 (e) Schedules. Seller shall prepare schedule(s) showing the calculation of the Section 45 Credits with respect to Coke sold to Purchaser during a year, not later than thirty (30) days
before Seller files its federal income tax return for such year. 
 (f) Recomputation. If Seller, and if applicable, any
Third Party Investor(s), is claiming more Section 45 Credits than the amount that Purchaser determines to be appropriate, then for purposes of this Section 3.2, Purchaser may elect to have the Sunoco Realized Value, and if applicable, the
Other Realized Value, determined based on such lower amount of Section 45 Credits (such lower amount referred to as the “Recomputed Section 45 Credit Amount”). If there is a later reduction in any Section 45 Credits claimed
by Seller or any Third Party Investor, then Purchaser’s liability under Section 3.3(d) shall be determined only with respect to such reduction below the Recomputed Section 45 Credit Amount. Seller has no obligation to Purchaser under
this Section 3.2 to the extent the amount of Section 45 Credits actually allowed exceed the Recomputed Section 45 Credit Amount. 
 (g) Acknowledgement. The Parties acknowledge that the Coke batteries located within the Plant must be placed in service on or before December 31, 2009 (the “Section 45 Qualification
Deadline”) in order to qualify for Section 45 Credits and that there is no guaranty that such Section 45 Qualification Deadline will be achieved by Seller. Accordingly, Seller owes no duty or obligation to Purchaser in respect of
completing the construction of the Plant or its batteries within such Section 45 Qualification Deadline, and shall have no liability to Purchaser whatsoever under this Agreement or otherwise if Coke does not qualify for Section 45 Credits
as a consequence thereof, even if arising out of the fault or misconduct of Seller. 
 3.3 Terms of Payment/Invoicing.


  
 10 









 (a) Provisional Monthly Invoices. During the Initial Year and each Contract Year, on
or after the tenth (10th) day before the end of each Month transpiring for the balance of the Term and any renewal thereof, Seller will submit to Purchaser a Written invoice in respect of each such Month. The invoiced amount for such Month
shall be the sum of (i) the product of the applicable Coke Price multiplied by Seller’s good faith estimate of the Coke Tonnage to be delivered to Purchaser during such Month (the “Estimated Coke Tonnage”), plus, (ii) Taxes
thereon, plus or minus, as applicable, (iii) the applicable adjustments set forth in Section 3.3(c). 
 (b) Final
Monthly Invoices. Revisions (in the form of, as applicable, credits or debits) to each provisional invoice will be made on a special Monthly final invoice delivered by Seller to Purchaser to reflect any debit or credit, as the case may be, in
respect of the negative or positive difference between the product of the applicable Coke Price multiplied by the Estimated Coke Tonnage for such Month and the product of the applicable Coke Price multiplied by the actual Coke Tonnage delivered to
Purchaser during such Month, including any applicable adjustments for Taxes. Each such invoice will be submitted to Purchaser within fifteen (15) days following the end of each applicable Month. 

(c) Invoice Adjustments. 
 (i) During the Initial Year and each Contract Year, amounts payable by Purchaser to Seller pursuant to Section 3.3(b) shall be subject to the following Monthly adjustments (as applicable):

 11 









 (A) Any credit or payment, as the case may be, as determined in accordance
with Section 3.1(c)(iv); and 
 (B) Any credit or payment, as the case may be, in respect of any positive
or negative difference between the Actual O&M Component and the Forecasted O&M Component, as determined in accordance with Section 3.1(c)(vi). 
 (d) Payment. Subject to Section 3.3(e), provisionally and Monthly invoiced amounts as set forth herein shall be due and payable in immediately available funds by wire transfer to accounts
identified by Seller or its designee on or within ten (10) days after each applicable invoice is delivered by Seller or its designee to Purchaser (the “Due Date”), and such payments shall not be subject to any right of set off or
other condition. Overdue amounts shall accrue interest at the Interest Rate from the applicable Due Date. Commencing the first Contract Year, the Due Date shall be set annually based on the payment terms set forth in Seller’s Coal purchase
contracts based upon the weighted average, in Tons, of the Coal to be delivered under such Coal purchase contracts, provided that the Due Date will be the greater of (i) ten (10) days, or (ii) twenty (20) fewer days than the
weighted average of the due dates for payment as set forth in such Coal purchase contracts, in each case after the applicable invoice is delivered by Seller or its designee to Purchaser. 

(e) Manifest Error Exception. If, based upon Manifest Error, Purchaser reasonably believes that any invoice incorporates
overcharged amounts in respect of amounts properly payable under this Agreement, then it shall notify Seller in Writing of such overcharge, including the amount and the basis of its belief, prior to the Due Date. Subject to the foregoing, undisputed
amounts shall be paid as set forth in Section 3.3(d), and the Parties shall attempt, in good faith, to agree upon the disputed amounts within fifteen (15) days after such Written notice is delivered by Purchaser. If the Parties cannot
resolve any such dispute within such fifteen (15) day period, then either Party may invoke the provisions of Section 9.2. Disputed amounts confirmed to be actually due by Purchaser shall be payable within five (5) Business Days, and
shall accrue interest at the Interest Rate from the applicable Due Date. If it is determined in accordance with Section 9.2 that Purchaser has overpaid Seller under this Agreement, then Seller shall promptly reimburse Purchaser for the full
amount of such overpayment, with interest in respect of such overpayment accruing at the Interest Rate from the date of such overpayment by Purchaser through the date of reimbursement by Seller. 

3.4 Reimbursement of Interconnection Costs. 
 (a) Interconnection Charges. Purchaser and Seller acknowledge that, as of the Effective Date, costs, fees and expenses in respect of developing and constructing improvements in respect of
(i) connecting the Cogeneration Plant to the local electrical energy grid, and (ii) completing transmission and distribution system upgrades required to accommodate new capacity in respect of electrical energy production from the
Cogeneration Plant (collectively, “Interconnection Costs”) have not been determined. Accordingly, the Parties acknowledge that such Interconnection Costs have not been incorporated into the Fixed Price Component. 

  
 12 









 (b) Reimbursement by Purchaser. Seller will pay the Interconnection Costs in a timely
manner, and will invoice Purchaser for such Interconnection Costs on a Monthly basis as such Interconnection Costs are incurred. Each such invoice will include reasonable support for the Interconnection Costs incurred during each invoice period, and
will be payable within fifteen (15) days following the delivery thereof by Seller to Purchaser. Overdue payments shall bear interest at the Interest Rate. 
 3.5 By-Products. Seller shall retain all By-Products for its own account. Seller shall retain all proceeds from the sale or other disposition of By-Products. 

3.6 Audit Rights. Purchaser or its designee shall have the right, during normal working hours of Seller, to review and inspect
such books and records of Seller and, as applicable, SunCoke as Purchaser deems reasonably necessary to verify any amounts payable by Purchaser under this Agreement. Purchaser shall provide Seller with at least two (2) Business Days Written
notice prior to its commencement of any such review and inspection. Such review and inspection shall take place at the place in which such books and records are customarily maintained. 

3.7 Production Turndown Adjustment Fee. In the event Purchaser requests a Production Turndown, in addition to the amounts payable
by Purchaser pursuant to Section 3.1(a)(iii), Purchaser shall pay Seller an amount equal to the sum of (a) the product of (x) $*****, multiplied by (y) the Monthly Coke Purchase Shortfall, and (b) the Lost Energy
Charge (the “Production Turndown Adjustment Fee”). 
 ARTICLE IV 

COAL BLENDS 
 4.1 Selection. The Coal Committee shall select, by majority vote, Coal Blends that conform to the Coal Blend Standards, and may make recommendations to Seller regarding the acquisition of Coals in
respect of this Agreement and related testing, blending, handling and delivery procedures. Purchaser and Seller shall each be entitled to exercise one vote in respect of Coal Committee matters. Meetings of the Coal Committee shall be scheduled at
intervals and at locations to be mutually agreed upon by the Parties. In the event of a tie, Purchaser shall have the final and deciding vote; provided, however, Purchaser shall not utilize such final and deciding vote to select a Coal Blend that
does not conform to the Coal Blend Standards. 
 4.2 Sampling and Testing. A qualified independent laboratory, reasonably
acceptable to both Parties, shall perform sampling, proximate analysis (including moisture analysis), total sulfur analysis, oxidation analysis, plastic behavior analysis, and petrography of each Coal shipment. Such sampling, analysis and
petrography shall be performed in accordance with ASTM Standards. The results of such analysis and petrography shall be promptly provided to each member of the Coal Committee in Writing, and shall be used for determining compliance with the Coal
Blend Standards in respect of each Coal Blend. 
 4.3 Unsuitability or Insufficiency of Coal Blends. If any Coal Blend
does not in practice conform to the Coal Blend Standards or if sufficient quantities thereof become unavailable, then Seller shall promptly inform Purchaser in Writing of such (applicable) 

  
 13 









 
nonconformity or unavailability. If, pending selection of any new Coal Blend, the use by Seller of the Coal Blend originally selected by for use at the Plant adversely affects the Plant or
Seller’s ability to comply with its obligations under this Agreement then, pending the selection of a new Coal Blend, Seller shall have the authority to utilize another Coal Blend that incorporates the Coals available at the Plant or Coals that
are otherwise reasonably available to Seller and which, in Seller’s reasonable judgment, meet or reasonably approximate the Coal Blend Standards. If such a Coal Blend is not available to Seller, then the Screened Coke Quality Standards and the
Coke Supply and Purchase Obligation shall be, as appropriate, adjusted at the reasonable discretion of Seller; provided, however, Seller shall provide Purchaser with Written notice of such circumstance, and the basis for any corresponding adjustment
to, as applicable, the Screened Coke Quality Standards and/or the Coke Supply and Purchase Obligation. 
 4.4 Authority of
Seller. Subject to Seller’s obligations in respect of Sections 4.1, 4.2 and 4.3, Seller shall retain the responsibility and authority for daily operating matters involving the Coal Blends and compliance with the Screened Coke Quality
Standards, without any requirement to consult with or obtain the approval of Purchaser. 
 ARTICLE V 

SCREENED COKE SAMPLING, ANALYSIS AND QUALITY 
 5.1 Coke Moisture and Screened Coke Quality. 
 (a) Coke and Screened
Coke Sampling and Analysis. Coke and Screened Coke will each be sampled by automatic swing arm cross cut samplers located within the Plant that will collect composite Coke and Screened Coke samples at least once each ***** hour production turn
in accordance with ASTM standards. Such samples will be analyzed by an independent laboratory selected by Seller and approved by Purchaser (which approval shall not be unreasonably withheld, conditioned or delayed) in accordance with ASTM Standards,
or such other standards agreed upon by the Parties in Writing. Purchaser shall be provided with a referee split of all samples. Such independent laboratory shall retain such samples for not less than thirty (30) days. The sulfur, ash, volatile
matter, and stability content of Screened Coke will be tested and analyzed on a daily basis for the purposes of determining whether (i) Coke is subject to being rejected as Nonconforming Coke, and (ii) any Coke Price adjustments pursuant
to the “Threshold” limits set forth in Schedule 5.1, based in each case upon an arithmetical average of such shift samples. Total moisture shall be determined on a Weekly basis based upon a composite of such Screened Coke shift samples. A
designated representative of Purchaser will be entitled to be present during such sampling, preparation and analysis upon reasonable verbal notice of its intention to be present during such sampling, preparation and analysis, and Purchaser may audit
such sampling and analysis procedures for the purpose of determining whether such procedures conform to ASTM Standards. Seller will report the results thereof to Purchaser as soon as those results are available. Absent Manifest Error, those results
shall be conclusive and binding on the Parties for the purposes of determining conformity with the Screened Coke Quality Standards and any adjustments to the Coke Price as set forth in Section 5.1(b) and Schedule 5.1. 

(b) Screened Coke Quality Standards. 

  
 14 









 (i) Subject to the availability of Coals that conform to the Coal Blend
Standards, Screened Coke shall conform to the Screened Coke Quality Standards set forth in the Schedule 5.1 and Seller will implement commercially reasonable measures to achieve conformity with the “mean” Screened Coke Quality Standards
set forth in Schedule 5.1. 
 (ii) Subject to the availability of Coals that conform to the Coal Blend Standards
and Section 5.1(c), if Screened Coke or Third Party Supplied Coke Tonnage does not conform to the “threshold” limits provided for in the Screened Coke Quality Standards set forth in Schedule 5.1, then the Coke Price in respect of such
Coke Tonnage will be adjusted as set forth in Schedule 5.1 as respects each such nonconformity. In addition, Seller will implement prompt corrective measures to correct any such nonconformity in respect of further Screened Coke shipments and will
promptly inform Purchaser in Writing of such corrective measures. 
 (iii) Subject to the availability of Coals
that conform to the Coal Blend Standards, if not less than ***** hours prior to pushing, Seller has reason to believe that the Plant will produce Screened Coke that exceeds or, as applicable, is less than the “reject” limits set forth in
Schedule 5.1 (“Nonconforming Coke”), then Seller shall notify Purchaser’s designee at the Middletown Plant in Writing thereof. Such notice will include the basis for Seller’s determination, its reasonable estimate of the quality
of such Nonconforming Coke (particularly with respect to the “reject” standards set forth in Schedule 5.1), and the estimated delivery time of such Nonconforming Coke. Following such notification but prior to the delivery of such
(presumptive) Nonconforming Coke, Purchaser may reject such (presumptive) Nonconforming Coke; provided, however, Seller may subsequently blend such (presumptive) Nonconforming Coke into other Coke such that such blended Coke does not exceed or, as
applicable, is not less than the “reject” limits set forth in the Screened Coke Quality Standards. Purchaser may rely on Seller’s notice as accurate and shall be deemed to have properly rejected such (presumptive) Nonconforming Coke
regardless of whether or not it is determined to meet the Screened Coke Quality Standards. 
 (iv) If such
(presumptive) Nonconforming Coke is later determined to meet the Screened Coke Quality Standards based upon sampling, preparation, testing and analysis set forth in Section 5.1(a), then Purchaser shall have no liability for having rejected such
(presumptive) Nonconforming Coke and Seller may thereafter deliver such Coke to Purchaser. 
 (v) If Screened
Coke is delivered to Purchaser and is subsequently determined to be Nonconforming Coke based upon sampling, preparation, testing and analysis set forth in Section 5.1(a), and such Nonconforming Coke is consumed or commingled with any other
screened coke acquired by Purchaser, then Seller shall be credited an amount equal to (i) the product of the (y) Coke Price multiplied by (z) the product of the Coke Tonnage from which such Nonconforming Coke Tonnage is derived (as
adjusted for quality pursuant to the 

  
 15 









 
Schedule 5.1), minus (ii) $***** per Ton in respect of such Nonconforming Coke Tonnage (the “Coke Price Discount”). Payment for such Nonconforming Coke shall be made in accordance
with Section 3.3. However, where Nonconforming Coke is not consumed or is not commingled with other screened coke acquired by Purchaser, Purchaser may either (y) reject such Nonconforming Coke by means of prompt Written notification
thereof delivered by Purchaser to Seller (provided such Written notice is delivered within three (3) Business Days following Seller’s notification to Purchaser of such Nonconforming Coke Tonnage), or (z) purchase such Nonconforming
Coke Tonnage for the Coke Price less the Coke Price Discount. Upon rejection of such Nonconforming Coke, title to such Nonconforming Coke shall revert to Seller and Seller shall accept all risk of loss, damage, or destruction therefore. 

(vi) As applicable, Seller shall be required to remove from Purchaser’s facilities any Nonconforming Coke that is
properly rejected by Purchaser. Seller will be responsible for all removal costs. Purchaser may require Seller to make up the corresponding shortfall pursuant to a reasonable shipment schedule to be specified by Purchaser. In addition, Seller shall
implement appropriate corrective measures prior to further Screened Coke deliveries, and shall promptly notify Purchaser in Writing of such corrective measures. 
 (c) Changes to Screened Coke Quality Standards. In conjunction with the annual review of the Coal Blends by the Coal Committee, or as reasonably required based on prevailing market conditions in
respect of Coal availability and price, Purchaser may request reasonable revisions to the Screened Coke Quality Standards. Promptly after receipt of Purchaser’s request, Seller will enter into good faith discussions with Purchaser regarding
such changes; provided, however, Seller will not be required to make any adjustment that would have a detrimental effect on (i) Coal Blend Standards; (ii) Seller’s economic returns (including the operating or capital costs associated
with the Plant, the “threshold” or “reject” Screened Coke Quality Standards), and/or (iii) contracts between Seller and third parties including Coal purchase contracts. Any increase or decrease in costs and charges
associated with any such change shall be for the account of Purchaser. If the Parties are unable to reach agreement as respects any such proposed revisions, then such dispute shall be subject to the dispute resolution procedures set forth in Article
IX. 
 5.2 Title. Seller warrants that at the time of delivery of Coke or Third Party Supplied Coke to Purchaser it shall
have good title and full right and authority to transfer such Coke or Third Party Supplied Coke to Purchaser, and that the title conveyed shall be good and its transfer shall be rightful and that such Coke or Third Party Supplied Coke shall be
delivered free from any security interest or other lien or encumbrance. 
 5.3 Exclusivity. THE WARRANTIES EXPRESSLY SET
FORTH IN THIS ARTICLE V ARE EXCLUSIVE AND ARE IN LIEU OF ALL OTHER WARRANTIES, WHETHER WRITTEN OR ORAL, IMPLIED IN FACT OR IN LAW, AND WHETHER BASED ON STATUTE, CONTRACT, TORT, STRICT LIABILITY OR OTHERWISE. THE WARRANTY OF MERCHANTABILITY AND
WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE ARE EXPRESSLY EXCLUDED AND DISCLAIMED.

 ARTICLE VI 
 OBLIGATIONS RELATED TO COKE SUPPLY AND DELIVERIES 
 6.1 Coke
Supply during the Initial Year. During the Initial Operating Period, Seller shall sell, and Purchaser shall purchase, all Coke from the Plant as such Coke is produced and delivered to the delivery points described in Section 6.3, subject to
Purchaser’s rejection rights in respect of Nonconforming Coke; provided, however, but subject to (i) Purchaser’s compliance with its performance obligations under this Agreement in respect of compliance with the Coal Blend Standards,
blending of coals in accordance with Section 4.3, and (ii) the availability of Coals that comply with the Coal Blend Standards (collectively, the “Requirements”), following the conclusion of the Initial Operating Period and for
the balance of the Initial Year thereafter, the Coke Supply and Purchase Obligation is a fraction of such Tonnage of Coke, the numerator of which is the number of days transpiring during each such period and the denominator of which is 365.

 6.2 Coke Supply and Purchase Obligation. 
 (a) Seller’s Supply Obligation. Subject to the Requirements and Section 6.7, for each Contract Year Seller’s obligation (“Coke Supply Obligation”) in respect of the Coke
Supply and Purchase Obligation is:

Delivery Point, and (ii) all Breeze produced by Seller and made available by Seller at the Breeze Delivery Point. 
 (c)
Ratability of Coke Production. In accordance with Prudent Operating and Maintenance Practices, but subject to the Requirements and Seller Force Majeure Event(s), following the Initial Operating Period Screened Coke deliveries pursuant to
Section 6.3 shall be made on a commercially reasonable ratable basis at intervals such that (subject to Seller’s Coke Supply Obligation) for any consecutive four (4) Week period, on a rolling basis, Seller shall deliver not less than
*****% of the Targeted Coke Production (the “Minimum Ratability Standard”). 
 6.3 Coke Deliveries. 


  
 17 









 (a) Screened Coke Delivery Points. All Screened Coke deliveries by Seller to
Purchaser shall be made by conveyor to the Screened Coke Conveyor Delivery Point or, when Purchaser’s conveyor is out of service, to either (i) the Screened Coke Rail Delivery Point or (ii) the Screened Coke Truck Delivery Point as
directed by Purchaser. In the case of such deliveries to the Screened Coke Rail Delivery Point or, as applicable, the Screened Coke Truck Delivery Point caused by Purchaser’s conveyor (“Purchaser’s Conveyor”) being out of
service, (y) Purchaser shall supply all transportation (as applicable, railcars or trucks) reasonably required to deliver such Screened Coke from the Screened Coke Rail Delivery Point or, as applicable, the Screened Coke Truck Delivery Point to
the Middletown Plant, and (z) the Parties shall reasonably cooperate in scheduling such rail and truck deliveries. 
 (b)
Seller’s Rights When Purchaser Wrongfully Refuses Delivery of Coke. If Purchaser refuses or, except as set forth in Section 8.2, below, is unable to accept any delivery of Screened Coke Tonnage, and such refusal or failure is a
breach of Purchaser’s obligations under this Agreement, then without in any way limiting Seller’s remedies in respect this Agreement, (i) Purchaser shall pay Seller an amount equal to the product of the Coke Price in respect of such
Screened Coke Tonnage; (ii) Purchaser will reimburse Seller for Seller’s actual handling costs associated therewith, including reasonable storage and re-screening costs, incurred by Seller in connection with the stockpiling of such
Screened Coke Tonnage; and (iii) the moisture content of such Screened Coke Tonnage, or any blending of such Screened Coke Tonnage with other Screened Coke Tonnage performed at Purchaser’s request, shall not be required to conform to the
moisture specification set forth in the Screened Coke Quality Standards; provided, however, (y) Seller shall not be obligated to store more than one thousand five hundred (1500) Tons of Screened Coke at the Plant on behalf of the Purchaser
at any point during the Term or any renewal thereof, and (z) in the event such storage capacity is exceeded, and such exceedance results from Purchaser’s refusal or inability to accept any delivery of Screened Coke Tonnage (including, as
applicable, Purchaser’s refusal or inability to remove Screened Coke Tonnage from the Screened Coke Truck Delivery Point), then Seller shall be entitled to reduce its stockpile of Screened Coke Tonnage by delivering the same by truck to the
Middletown Plant (to a delivery point therein to be reasonably designated by Purchaser), and Seller’s reasonable direct costs in respect thereof shall be reimbursed by Purchaser to Seller on a Monthly basis in accordance with Section 3.3.
Where Seller is entitled to such reimbursement from Purchaser, it shall promptly notify Purchaser in Writing of the amount and basis for determining Seller’s direct costs, which Written notice will include reasonable support for such direct
costs; provided, however, if Purchaser fails to pay for such Screened Coke Tonnage, then Seller may resell the same upon Written notification by Seller to Purchaser of its intention to do so. Where such resale is made in good faith and in a
commercially reasonable manner, Seller shall recover the positive difference (if any) between (i) the sum of (v) the product of the applicable (A) Coke Price multiplied by (B) such Screened Coke Tonnage, plus (w) reasonable
storage and re-screening costs and degradation and handling losses in respect thereof, plus (x) any Incidental Damages in respect thereof, on the one hand, and (ii) the sum of the (y) resale proceeds in respect of such Coke Tonnage,
plus (z) expenses saved (if any) as a consequence of Purchaser’s breach. 
 (c) Breeze Storage and Deliveries.
The Parties acknowledge that (i) the Plant will incorporate storage capacity in respect of Breeze Tonnage of ***** Tons, (ii) Breeze will be delivered to Purchaser at the Breeze Delivery Point, (iii) Seller and Purchaser will
reasonably 

  
 18 









 
cooperate in scheduling Breeze deliveries, and (iv) Purchaser will provide and make available a sufficient number of trucks to load and transport Breeze Tonnage such that Seller’s
stockpile of Breeze does not exceed such storage capacity. In the event such storage capacity is exceeded, and such exceedance results from Purchaser’s refusal or inability to remove Screened Coke Tonnage from the Breeze Delivery Point, then
Seller shall be entitled to reduce its stockpile of Breeze Tonnage, and Seller’s reasonable direct costs in respect thereof shall be reimbursed by Purchaser to Seller on a Monthly basis (as a credit) in accordance with Section 3.3. Where
Seller is entitled to such reimbursement from Purchaser, it shall promptly notify Purchaser in Writing of the amount and basis for determining Seller’s direct costs, which Written notice will include reasonable support for such direct costs.

 (d) Risk of Loss. Title and all risk of loss, damage or destruction in respect of (i) Screened Coke Tonnage will
pass to and be assumed by Purchaser upon its delivery to the Screened Coke Conveyor Delivery Point or, as applicable, the Screened Coke Rail Delivery Point or the Screened Coke Truck Delivery Point, and (ii) Breeze will pass to and be assumed
by Purchaser upon its loading into trucks supplied by Purchaser at the Breeze Delivery Point; provided, however, title and risk of loss of Nonconforming Coke shall not pass to Purchaser if it is rejected by Purchaser. 

6.4 Third Party Supplied Coke. If, at any point during any Contract Year, Seller has reason to believe that it will be unable to
produce and deliver sufficient Coke to meet the minimum range set forth in Section 6.2(a) of the Coke Supply and Purchase Obligation or the Minimum Ratability Standard, then Seller shall promptly provide Written notice of the same to Purchaser
and Seller shall exercise commercially reasonable efforts to obtain Third Party Supplied Coke in respect of the product of either such shortfall (measured in Tons) multiplied by ***** (each, as applicable, a “Coke Production Shortfall”).
Furthermore, if Purchaser has a reasonable basis to conclude that Seller will be unable to deliver sufficient Coke meet such minimum range of the Coke Supply and Purchase Obligation or the Minimum Ratability Standard, then Purchaser shall provide
Written notice thereof to Seller (including the basis of such conclusion), and following Seller’s receipt of such Written notice Seller shall, within a reasonable time under the circumstances, provide Purchaser with Written reasonable
assurances that it will comply with the minimum range of the Coke Supply and Purchase Obligation or, as applicable, the Minimum Ratability Standard (collectively, “Seller’s Reasonable Assurance Obligations”). If Seller does not comply
with Seller’s Reasonable Assurance Obligations then, subject to Section 6.5, it shall exercise commercially reasonable efforts to obtain Third Party Supplied Coke in respect of such Coke Production Shortfall. The quality of such Third
Party Supplied Coke shall not exceed or, as applicable, be less than the “reject” limits set forth in Schedule 5.1. The price Purchaser shall pay for such Third Party Supplied Coke shall be the lesser of (i) the price of such Third
Party Supplied Coke (as adjusted in accordance with Schedule 5.1) delivered to the Middletown Plant, or (ii) the current Coke Price (as adjusted in accordance with Schedule 5.1). Seller shall arrange for the shipment and delivery of Third Party
Supplied Coke and shall exercise reasonable, good faith efforts to arrange for such deliveries in accordance with Purchaser’s requested delivery schedule. Promptly following the delivery to the Middletown Plant of any Third Party Supplied Coke
shipment, Seller shall deliver by facsimile transfer or electronic mail, or by such other method agreed upon by the Parties in Writing, an invoice for each such shipment to the Purchaser. Payment by Purchaser to Seller for such Third Party Supplied
Coke in respect of the Month during which it is supplied to Purchaser shall be

made within ten (10) days following Seller’s delivery of such invoice to Purchaser; provided, however, and except as respects the occurrence of Seller Force Majeure Event(s), if
Seller reasonably determines that the Coke production capacity of the Plant is or will be less than *****% of Targeted Coke Production, and Seller is unable to establish or restore such production capacity notwithstanding its good faith and
commercially reasonable efforts to do so, then Seller’s obligation to cover such Coke Production Shortfall (either in respect of Third Party Supplied Coke or Purchaser Obtained Coke) shall not exceed twelve (12) months in duration (the
“Production Capacity Liability Limitation”). 
 6.5 Purchaser Obtained Coke. In the event Seller (i) fails
to comply with its obligations in respect of Section 6.4 (including Seller’s Reasonable Assurances Obligations and its obligation to obtain Third Party Supplied Coke sufficient to satisfy the Minimum Ratability Standard), or
(ii) notifies Purchaser that it has reason to believe that it will be unable to cover any applicable Coke Production Shortfall with Third Party Supplied Coke, then Purchaser may make commercially reasonable arrangements to acquire Purchaser
Obtained Coke sufficient to cover such Coke Production Shortfall, and Purchaser shall so notify Seller in Writing of such arrangements. Subject to the Production Capacity Liability Limitation, if the commercially reasonable price of Purchaser
Obtained Coke Tonnage plus the actual, direct costs incurred by Purchaser to deliver such Purchaser Obtained Coke Tonnage to the Middletown Plant is greater than the sum of (i) the product of (y) the current Coke Price for Coke (as
adjusted in accordance with Schedule 5.1) divided by ***** multiplied (z) by such Coke Tonnage, and (ii) the applicable Purchaser freight cost, then Seller shall reimburse Purchaser for the amount of such excess. In the event Purchaser
secures Purchaser Obtained Coke, then it shall use commercially reasonable efforts to limit its use of Purchaser Obtained Coke to the time period for which Purchaser reasonably believes, based on facts and circumstances disclosed in Writing to
Purchaser by Seller, that a Coke Production Shortfall will not be covered by Coke or Third Party Supplied Coke Tonnage. 
 6.6
Purchaser’s Conveyor. In the event Purchaser’s Conveyor is not operating as of the commencement of Coke production at the Plant such that Purchaser’s conveyor can accept all Coke deliveries, then (pending the successful
completion and testing of Purchaser’s Conveyor) all Screened Coke deliveries shall be to the Screened Coke Rail Delivery Point or Screened Coke Truck Delivery Point, and such deliveries shall be subject to the terms, conditions and requirements
in respect thereof set forth in Section 6.3. 
 6.7 Production Turndown. 

(a) To assist Purchaser in its preservation of working capital during periods when it experiences a significant reduction in the demand
for steel, AK will have the right, exercisable on or after one (1) year from the commencement of Coke sales, to nominate a Production Turndown, provided that the Production Turndown Conditions are satisfied. 

(b) Purchaser must provide Seller at least forty-five (45) days (but not more than sixty (60) days) prior Written notice (the
“Production Turndown Notice”) of its desire to nominate a Production Turndown. The Production Turndown Notice shall specify the Production Turndown Period and the quantity of Coke to be taken during the Production Turndown Period.


  
 20 









 (c) Purchaser may increase the amount of Coke it desires to purchase during a Production
Turndown Period (a “Production Turndown Increase”) upon at least forty-five (45) days prior Written notice to Seller (the “Production Turndown Increase Notice”), provided that (i) the Coal Committee is able to procure
Coal in sufficient quantity and meeting the Coal Blend Standards to satisfy such increased Coke demand, and (ii) Purchaser and Seller are able to agree upon a revised Forecast of O&M Expenses for the remainder of the Production Turndown
Period. 
 (d) Within fifteen (15) days following its receipt of a Production Turndown Notice or a Production Turndown
Increase Notice, Seller shall prepare and provide to Purchaser a revised Forecast that sets forth in reasonable detail its good faith estimate of the O&M Expenses in respect of the Plant for the Production Turndown Period. For the avoidance of
doubt, such O&M Expenses include operating and maintenance costs in respect of the Cogeneration Plant notwithstanding the circumstance that payments in respect of electrical energy produced by such Cogeneration Plant are made pursuant to the
Related Energy Sales Agreement. Such Forecast shall be based on the criteria set forth in Section 3.1(c)(iii) as adjusted to take into account the effect of the Production Turndown or Production Turndown Increase. Such Forecast shall further be
adjusted to reflect the deferment of costs related to the Production Turndown or Production Turndown Increase, to the extent that such costs can reasonably be deferred without adversely impacting the integrity, performance or safe operation of the
Plant, as determined in Seller’s sole discretion. Within fifteen (15) days following Seller’s delivery of such Forecast to Purchaser, Seller and Purchaser shall confer in good faith for the purpose of reviewing and approving such
Forecast. If, within fifteen (15) days thereafter, the Parties do not agree upon such Forecast, then the Production Turndown or Production Turndown Increase, as applicable, shall not become effective. Neither Party shall have the right to
submit a dispute regarding the Forecast to arbitration in accordance with Section 9.2. If the Parties agree upon such Forecast, it shall be the Forecast used to determine the Forecasted O&M Component pursuant to Section 3.1(c).

 ARTICLE VII 
 CHANGES IN GOVERNMENTAL REQUIREMENTS 
 7.1 Government Mandated
Additional Expenditures. 
 (a) Notification. If, following the date of this Agreement, Seller determines that a
change in Governmental Requirements may materially burden its performance of its obligations under this Agreement, then Seller shall so notify Purchaser in Writing. Seller’s performance shall be materially burdened where any such Governmental
Requirement has a material adverse economic impact on Seller, including such impacts in respect of (i) the Screened Coke Quality Standards; (ii) the Coal Blend Standards, (iii) the Guaranteed Coke Yield Percentage; (iv) the cost
of operating or maintaining the Plant (including associated capital costs); (v) the production capacity of the Plant (including Coke and electrical energy); or (vi) Seller’s performance obligations to third parties related to Coal
purchasing, transportation or handling contracts. Such notice shall incorporate Seller’s good faith proposals for complying with those changes in Governmental Requirements, including the estimated cost thereof. 

  
 21 









 (b) Good Faith Negotiations. During the sixty (60) day period following delivery
of any such notice, Seller and Purchaser shall negotiate in good faith to reach agreement as to (i) whether any such change in Governmental Requirements should be challenged, including the scope and manner of such challenge; and (ii) the
most economical and commercially prudent methods for complying with such change in Governmental Requirements. 
 (c)
Implementation. If such negotiations result in agreement as to whether to challenge the change in Governmental Requirements or the methods for complying with the change in Governmental Requirements, then Seller shall promptly implement such
challenge or methods as appropriate. Costs and charges associated with any such challenge (including attorneys’ and consultants’ fees, and fines and penalties) shall be borne equally by Seller and Purchaser. If no such agreement is reached
or if such challenge is unsuccessful, then Seller will implement commercially reasonable methods for complying with the change in Governmental Requirements. In connection therewith, any associated Government Mandated Additional Capital Expenditures
or Government Mandated Additional Expenses shall be performed at the lowest practicable cost at the time each such cost is incurred. 
 7.2 Government Mandated Additional Capital Expenditures. Government Mandated Additional Capital Expenditures shall have an assumed useful life equal to the greater of seven (7) Contract Years
or the remainder of the Term following completion of the Government Mandated Additional Capital Expenditures. As soon as the Government Mandated Additional Capital Expenditures have been completed, the monthly amortized cost thereof for the
remaining months of the Term will be calculated based on the applicable examples set forth in Schedule 7.2, and such allocated monthly amortized cost shall be payable by Purchaser to Seller in accordance with Section 3.3; provided, however, if
Seller incurs a Government Mandated Additional Capital Expenditure and if the remainder of the Term is less than seven (7) Contract Years, then Purchaser shall not be obligated to pay to Seller the unamortized balance of such Government
Mandated Additional Capital Expenditure. 
 ARTICLE VIII 

FORCE MAJEURE EVENT(S) 
 8.1 Seller Force Majeure Event(s). 
 (a) Seller Force Majeure Event(s) are:

 (i) acts of God, acts of the public enemy, insurrections, riots, strikes, lockouts, boycotts, floods,
interruptions to transportation, actions or inactions of a Governmental Authority, embargoes, acts of military authorities or other causes of a similar nature which wholly or partly prevent the production, transportation or delivery of Coke; or

 (ii) the unavailability of sufficient quantities of Coals utilized for any Coal Blend, or transportation
services in respect thereof; 
 provided, that no event shall constitute a Seller Force Majeure Event unless such event is beyond the reasonable
control of and without the fault or negligence of Seller and which by the exercise 

  
 22 









 
of due foresight Seller could not reasonably have been expected to avoid and which Seller is unable to overcome by the exercise of due diligence and reasonable care. 

(b) Seller will provide Purchaser with prompt Written notice of the nature and probable duration of each Seller Force Majeure Event and
of the extent of its effects on Seller’s performance hereunder, including its good faith estimate of the amount of Coke, if any, Seller will be able to deliver to Purchaser during such Seller Force Majeure Event. Seller will exercise
commercially reasonable efforts to deliver to Purchaser the amount of Coke Tonnage that Seller notifies Purchaser it will be able to deliver during each Seller Force Majeure Event. 

(c) Seller will use commercially reasonable efforts to limit the effects and duration of each Seller Force Majeure Event, including (as
applicable) restoring any damaged property necessary to reinstate the obligations of Seller under this Agreement, selecting alternate Coals for a Coal Blend that, in Seller’s reasonable judgment, conforms to or reasonably approximates the Coal
Blend Standards and, to the extent reasonably possible, that is calculated to produce Screened Coke that conforms to or approximates the Screened Coke Quality Standards, and supporting Purchaser in locating alternate sources of substitute coke
Tonnage for the duration of such Seller Force Majeure Event; provided, however, nothing in this Section shall be deemed to require Seller to resolve any strike or other labor dispute except on terms that are satisfactory to Seller in its sole
discretion. Purchaser’s obligation to purchase Coke shall be limited to that portion of the Coke Tonnage (excluding Nonconforming Coke Tonnage) that Seller is able to deliver to Purchaser, but in any event not in excess of that which Seller
indicated that it could supply to Purchaser in Seller’s notice of Seller Force Majeure Event provided pursuant to Section 8.1(b). Once Seller’s ability to deliver Coke is no longer suspended as a result of the applicable Seller Force
Majeure Event, the obligations of Seller and Purchaser under this Agreement will be reinstated with a prorated portion of the remaining of the Coke Supply and Purchase Obligation in respect of the Contract Year during which Seller’s ability to
perform hereunder is no longer suspended as a result of such Seller Force Majeure Event. 
 8.2 Purchaser Force Majeure
Event(s). 
 (a) Purchaser Force Majeure Event(s) are acts of God, acts of the public enemy, insurrections, riots, strikes,
lockouts, boycotts, floods, interruptions to transportation, actions or inactions of a Governmental Authority, embargoes, acts of military authorities or other causes of a similar nature which in whole or in part prevent Purchaser from being able to
accept Coke from Seller; provided, that no event shall constitute a Purchaser Force Majeure Event unless such event is beyond the reasonable control of and without the fault or negligence of Purchaser and which by the exercise of due foresight
Purchaser could not reasonably have been expected to avoid and which Purchaser is unable to overcome by the exercise of due diligence and reasonable care. 
 (b) Purchaser will provide Seller with prompt Written notice of the nature and probable duration of each Purchaser Force Majeure Event and of the extent of its effects on Purchaser’s performance
hereunder; provided, however, during such Purchaser Force Majeure Event, Purchaser shall be obligated to purchase from Seller all Coke Tonnage that meets its requirements (it being understood that Purchaser’s Ashland Works’ blast furnace
under normal operation currently obtains all of its coke from its Ashland, Kentucky coke plant and may not 

  
 23 









 
have any requirement for Coke Tonnage), in respect of any blast furnaces that may continue to be operated by Purchaser and its Affiliates during the Purchaser Force Majeure Event (such Tonnage to
be priced at the applicable Coke Price f.o.b. the Plant). 
 (c) Purchaser will use commercially reasonable efforts to limit the
effects and duration of each Purchaser Force Majeure Event, including (as applicable) restoring any damaged property necessary to fully reinstate the obligations of Purchaser under this Agreement; provided, however, nothing in this Section shall be
deemed to require Purchaser to resolve any strike or other labor dispute except on terms that are satisfactory to such Purchaser in its sole discretion. Once Purchaser’s ability to perform is no longer suspended as a result of the applicable
Purchaser Force Majeure Event, the obligations of Purchaser and Seller under this Agreement will be reinstated with a prorated portion of the remaining Coke Supply and Purchase Obligation in respect of the Contract Year during which Purchaser’s
ability to perform hereunder is no longer suspended as a result of such Purchaser Force Majeure Event. 
 ARTICLE IX

 DISPUTE RESOLUTION 
 9.1 Attempt at Resolution. Except for claims or causes of action in respect of Equitable Relief, and subject to Sections 3.1(c)(iv) and 7.1(b), should any claim, cause of action or dispute
(collectively, a “Dispute”) arise out of any of the provisions of this Agreement, the Parties shall first attempt in good faith to resolve such Dispute within thirty (30) days after either Party notifies the other that a Dispute
exists. No Party may commence an arbitration under Section 9.2 below until after the passage of such thirty (30) day period. 
 9.2 Interpretation and Dispute Resolution. 
 (a) Except as respects the
exercise or prosecution of claims or causes of action for Equitable Relief, for which the Parties shall have the right to proceed in any court of appropriate jurisdiction, any Dispute not resolved pursuant to (as applicable) Sections 3.1(c)(iv),
7.1(b) or 9.1 between the Parties arising out of or relating to this Agreement, the Related Energy Sales Agreement, the Equipment Agreement, the relationship of the Parties created by those agreements, or the breach, validity or enforceability of
those agreements shall be resolved by binding arbitration pursuant to the terms of the United States Arbitration Act, whether or not federal jurisdiction is obtained. Any and all arbitration(s) hereunder shall be conducted in Cincinnati, Ohio in
accordance with the Commercial Arbitration Rules (the “Rules”) of the American Arbitration Association. 
 (b) Any and
all such arbitration(s) shall be conducted by a panel of three (3) neutral arbitrators. The claimant shall appoint an arbitrator when it serves its demand for arbitration, the respondent shall submit an answering statement within thirty
(30) days of service of the demand for arbitration and shall at that time appoint an arbitrator, and the two Party-appointed arbitrators shall select a third arbitrator to chair the arbitration within fifteen (15) days after service of the
answering statement. If the Party-appointed arbitrators are unable to agree upon a third arbitrator, then the third arbitrator shall be appointed in accordance with the Rules. 

  
 24 









 (c) The arbitration award by the arbitration panel shall be final and binding, shall include
interest at the Interest Rate and, unless the arbitrator panel expressly determines them not to be appropriate, shall include costs, including reasonable attorneys’ fees, together with interest at the Interest Rate. Any arbitration award may be
enforced by the state or federal courts sitting in Cincinnati, Ohio or any other court of competent jurisdiction (including any jurisdiction in which the Party against whom the award is sought to be enforced holds or keeps assets). 

(d) Upon the date of an arbitration award pursuant to this Section 9.2, if it is determined that an amount is due from one Party to
the other Party, then such amount will be paid to the Party to whom it is due within ten (10) days from the Written determination of the arbitration panel. Overdue payments shall bear interest at the Interest Rate. The failure by such Party to
pay any amount due or otherwise take the required actions within the required time hereunder shall be a Purchaser Event of Default or Seller Event of Default, as applicable. 
 9.3 Consolidation. If the Parties initiate multiple arbitration proceedings (i) relating to this Agreement, the Related Energy Sales Agreement and/or the Equipment Agreement, or (ii) for
which the subject matters are related by common questions of law or fact, then all such proceedings shall be consolidated into a single arbitral proceeding heard by the same arbitral panel. The arbitral panel shall be authorized to establish
procedures which it deems appropriate in its discretion to adjudicate consolidated Disputes, including bifurcating the issues or issuing interim awards.

 1. Guarantors guarantee to AK the full performance
of all Guaranteed Obligations. Guarantors understand, agree and confirm that AK may enforce this Guaranty against Guarantors without first proceeding against Seller.

the obligations and performance of Seller; (b) any reduction of any such other guaranty or undertaking; (c) any dissolution, termination or increase, decrease or change in personnel by Seller; (d) any payment made to AK in respect of

to cure such default within the applicable cure period set forth in the Coke Purchase Agreement. 
 3. Other than the notice
required to be given to Guarantors as specified in Section 2 of this Guaranty, Guarantors hereby waive notice of acceptance of this Guaranty and notice of any liability to which it may apply, and waive promptness, diligence, presentment, demand

except payment in full of the Guaranteed Obligations. 
 6. This Guaranty is a continuing one and all liabilities to which it
applies or may apply under the terms hereof shall be conclusively presumed to have been created in reliance hereon. No failure or delay on the part of AK in exercising any right, power or privilege hereunder shall operate as a waiver thereof; nor

Guarantors to any other further notice or demand in similar or other circumstances or constitute a waiver of the rights of AK to any other or further action in any circumstances without notice or demand. It is not necessary for AK to inquire into
the capacity or powers of Seller or the officers, directors, or agents acting or purporting to act on its behalf, and any indebtedness made or created in reliance upon the professed exercise of such powers shall be guaranteed hereunder.

9. If and to the extent that Guarantors make any payment or performance to AK pursuant to or in respect of this Guaranty, then any claim
which Guarantors may have against Seller by reason thereof shall be subject and subordinate to the prior payment and performance in full of the Guaranteed Obligations to AK. 
 10. Guarantors hereby agree to pay all reasonable out-of-pocket costs and expenses of AK (including, without limitation, the reasonable fees and disbursements of counsel employed by AK) in connection with
the enforcement of this Guaranty and any amendment, waiver or consent relating hereto against Guarantors.

 These quality standards and price adjustments are for use on Screened Coke with a minimum bottom coke size of
*****”. 
 Ash and Total Sulfur Daily Standards – Each of the daily Screened Coke quality standards (Target, Quality Threshold
and Reject Standard) for ash and sulfur will be established based upon the test results of the daily sample(s) of the corresponding coal charged to the ovens. The daily Coke ash standard will be derived from the ash content of the coal charged,
adjusted for the expected coke yield formula (*****% minus the volatile matter content of the coal charged minus the expected *****% burn loss). By way of example, if the daily coal sample(s) result in an average ash content of *****% and an average
volatile matter content of *****%, then the daily standards for ash are: (Target = *****%, Quality Threshold = *****% and Reject Standard = *****%). The daily sulfur standards will be derived from the sulfur content of the coal charged, adjusted for
the expected coke retention factor of *****. By way of example, if the daily coal sample(s) result in an average sulfur content of 1.00%, then the daily standards for sulfur are: (Target = *****%, Quality Threshold = *****% and Reject Standard =
*****%). 
 Stability Penalty and Credit – For each ***** point variation in respect of Coke Tonnage that contains less than *****
Stability, the Coke Price will be decreased by $***** for such Coke Tonnage. For each one (1) point variation in respect of Coke Tonnage that contains more than ***** Stability, the Coke Price will be increased by $***** for such Coke Tonnage.
For Coke that measures between ***** stability and ***** stability, there shall be no adjustment to the Coke Price. 

  

SCHEDULE 5.1 
 PAGE 1 








 Moisture Penalty and Premium – For each *****% variation in moisture over *****%, the Coke Price
will be decreased $***** per ton for such coke tonnage. For each *****% variation in moisture under *****%, the Coke Price will be increased $***** per ton. 
 For coke that measures moisture between *****% and *****%, there shall be no adjustments to the Coke Price. For any day that Coke is rejected due to moisture content greater than the Reject Standard, such
tonnage will be excluded from the weekly average moisture calculation for quality adjustments. 
 Pro-Rata
Adjustments: 
 For ash, volatile matter, sulfur and moisture, any percentage over the threshold amount shall be pro-rated for
***** percentage point increment exceedance. By way of example, a volatile matter percentage of *****% will result in a Coke Price decrease of $*****. 
 Testing Frequency: 
 Moisture, sulfur, ash, volatile matter and
stability will be tested and analyzed on a daily basis. Results for moisture shall be arithmetically averaged on a weekly basis for Coke Price adjustments. For sulfur, ash, volatile matter and stability, if multiple samples are taken for a single
day, the results thereof shall be arithmetically averaged for that day for Coke Price adjustments.
