 ARTICLE III

 COKE PRICE AND PAYMENT TERMS 
 3.1 Coke Price. 
 (a) Components. 

(i) During the period of September 1, 2009 through December 31, 2009, the Coke Price is the sum of
(A) $***** per Ton of Coke, and (B) any Per Ton Fuel Surcharge; and 
 (ii) During the period of
January 1, 2010 through December 31, 2010, the Coke Price is the sum of (A) $***** per Ton of Coke, (B) the Per Ton Railroad Rate Index Charge and (C) any Per Ton Fuel Surcharge; and 

(iii) During each Contract Year commencing January 1, 2011, 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. 

  
 7 








 (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) Forecasted O&M Component, Actual O&M Component and Annual
True-Up. 
 (i) [Intentionally omitted] 

(ii) At least sixty (60) days prior to January 1, 2011 and the commencement of each subsequent 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 Coke Plants 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. 
 (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 Coke Plants; (ii) historic operations and maintenance history at the Coke Plants; (iii) subject to Article VII, compliance with
Governmental Requirements in respect of the Coke Plants, including Government Mandated Additional Expenses; (iv) property taxes in respect of the Coke Plants; (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 Coke Plants; (vii) Prudent Operating and Maintenance Practices; (viii) the reasonable cost of all premiums 

  
 8 








 
or, as applicable, allocations, in respect of required and commercially reasonable insurance coverages for the Coke Plants, Coke Plant operations, and employees of Seller (provided such
allocations or premiums constitute O&M Expenses), and (ix) other reasonable conditions specific to the Coke Plants 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, 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, 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 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 Coke Plants set forth in the approved Forecast for the applicable Contract Year ÷ Coke Plants 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) in respect of the Cogeneration Plant set forth in the approved
Forecast for the applicable Contract Year ÷ *****% of the Coke Plants Targeted Coke Production in respect of the Coal Blend(s) to be utilized during such Contract Year]. 

  
 9 








 (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 = actual O&M Expenses in respect of the Coke Plants for the applicable Contract Year ÷ actual Coke
Tonnage produced at the Coke Plants during such Contract Year (including Nonconforming Coke Tonnage rejected by Purchaser) + [actual O&M Expenses in respect of the Cogeneration Plant for the applicable Contract Year ÷ *****% of the actual
Coke Tonnage produced at 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 *****% 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 for 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. 
 (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 Coke Plants, 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 

  
 10 









 
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 Coke Plants 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 (1 – *****) 

(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, plus a *****% 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 

  
 11 









 
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 track scales
operated by Seller. Such scales shall have an accuracy of not less than 0.25% and shall be calibrated by an independent third party at a minimum of once per year or more often as required by the manufacturer’s instructions or Prudent Operating
and Maintenance Practices, 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, starting in the Contract Year commencing January 1, 2010, if any Coke qualifies for a credit under 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. 

(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; 

  
 12 









 
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, 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 

  
 13 









 
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. 
 3.3 Terms of
Payment/Invoicing. 
 (a) Provisional Shipment Invoices. On or promptly following the date of each Shipment during
the Term and any renewal thereof, Seller will submit to Purchaser in Writing a provisional invoice in respect of each such Shipment. The invoiced amount for such Shipment shall be the sum of (i) the product of (x) the applicable Coke Price
(based on Seller’s good faith estimate of Coal costs) multiplied by (y) the Coke Tonnage in respect of such Shipment, plus (ii) amounts payable by Purchaser to Seller in respect of any Third Party Supplied Coke, as set forth in
Section 6.4, plus (iii) Taxes thereon, plus or minus, as applicable, and (iv) the applicable adjustments set forth in Section 3.3(c). 
 (b) Final Invoice. Revisions to the provisional invoice set forth in Section 3.3(a) will be made on a special Monthly final invoice delivered to Purchaser to reflect actual adjustments to the
Coal costs for Coke delivered to Purchaser during the preceding Month and, as applicable, any amounts payable in accordance with Section 3.3(c). That invoice will be submitted to Purchaser within fifteen (15) days following the end of each
applicable Month. The final invoice shall incorporate, as applicable, credits due to Purchaser or any additional amounts due from Purchaser. In the case of any credits, such credits will be deducted from the next succeeding invoice(s) submitted to
Purchaser. 
 (c) Invoice Adjustments. 

(i) Throughout the Term, amounts payable by Purchaser to Seller pursuant to Section 3.3(b) shall be subject to the
following Monthly adjustments (as applicable):

(H) Any credit or payment, as the case may be, as determined in accordance with Section 3.1(c)(iv); and 

(I) 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), 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 (i) for the period from
September 1, 2009 through December 31, 2010, on or within twenty-three (23) days after each applicable invoice is delivered by Seller or its designee to Purchaser, and (ii) for the period commencing January 1, 2011 through
the end of the Term, as set forth in the last sentence of this Section 3.3(d) (clause (i) or (ii) of this paragraph, as applicable, 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 January 1, 2011, 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 seven (7) fewer days than the due date for payment as set forth in such Coal purchase contracts.

 (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 

  
 15 









 
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 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”).

 3.5 By-Products; Option to Purchase Breeze. Seller shall retain all By-Products for its own account, and Seller shall
retain all proceeds from the sale or other disposition of By-Products; provided, however, during each Calendar Year starting in 2010, Purchaser may, at its option, purchase *****% of the available Breeze for the market price therefore FOB the Coke
Plants in effect as of the date Purchaser exercises that option. In order to exercise that option, Purchaser must notify Seller, in Writing, of its exercise thereof at least ninety (90) days prior to the commencement of the applicable Calendar
Year. In the event that Purchaser exercises its option to purchase Breeze, Seller shall deliver Breeze to Purchaser at the Breeze Delivery Point and Seller and Purchaser shall reasonably cooperate in scheduling Breeze deliveries. 

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. 

ARTICLE IV 

COAL BLENDS 
 4.1 Selection. Starting Contract Year 2011, 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. The Parties acknowledge that a portion of the Coals have been committed to be purchased through March 31, 2012 (the
“Committed Coal”) and, therefore, the Coal Committee will select the remaining Coals required for the Coal Blend taking into account these prior commitments. The quantity, price and specifications of the Committed Coal are set forth on
Schedule 4.1. 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. 

  
 16 









 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) 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 Coke Plants adversely affects the Coke Plants 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 Coke Plants 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 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 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 Coke Quality Standards, without any requirement to consult with or obtain the approval of Purchaser. 

ARTICLE V 

COKE SAMPLING, ANALYSIS AND QUALITY 
 5.1 Coke Moisture and Coke Quality. 
 (a) One (1) representative Coke
sample increment will be taken from the loading belt during the loading of each railcar. Each such increment will be a complete cross section cut as taken from the loading belt by the mechanical sampling system. All such samples shall be stored in a
closed container situated within a controlled, indoor environment prior to the testing and analysis thereof as required in Section 5.1(c). Upon twenty-four (24) hour notice to Seller, Purchaser shall be entitled to be present during the
sampling, preparation, analysis, and loading of Coke shipments. 
 Coke samples will be prepared on a daily basis by an
independent laboratory in accordance with ASTM Standards or, where no ASTM Standards apply, in accordance with generally accepted industry standards. Seller shall notify such independent laboratory to retain such samples for no less than thirty
(30) days from the date the samples are prepared. 

  
 17 









 Moisture, size, sulfur, ash, volatile matter and stability of Coke will be tested and
analyzed on a daily basis, and the results thereof shall be arithmetically averaged, on a Shipment basis, to determine conformity with the Coke Quality Standards applicable thereto. Such testing and analysis shall be performed in accordance with
ASTM Standards or other procedures approved by the Parties in Writing, and shall govern for the purposes of determining conformity with the Coke Quality Standards. All daily results (prior to any averaging thereof), and all consolidated results
utilized to determine compliance with the Coke Quality Standards, will be provided by Seller to Purchaser promptly in Writing prior to the delivery of the applicable Shipment. Absent Manifest Error, those results shall be conclusive and binding on
the Parties for the purposes of determining conformity with the Coke Quality Standards and any adjustments to the Coke Price as set forth in Section 5.1(b) and Schedule 5.1. Purchaser shall have the right to conduct an audit of all results of
such sampling, preparation, testing and analysis for the purpose of auditing Seller’s compliance with such sampling, preparation, testing and analysis procedures. 
 (b) Coke Quality Standards. 
 (i) Subject to the
availability of Coals that conform to the Coal Blend Standards, Coke shall conform to the Coke Quality Standards set forth in the Schedule 5.1 and Seller will implement commercially reasonable measures to achieve conformity with the “mean”
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 Coke or Third Party Supplied Coke Tonnage does not conform to the “threshold” limits provided for in the 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 Coke shipments and will
promptly inform Purchaser in Writing of such corrective measures. 
 (iii) If 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 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 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 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 

  
 18 









 
Coke, title to such Nonconforming Coke shall revert to Seller and Seller shall accept all risk of loss, damage, or destruction therefore. 

(iv) Seller may blend up to *****% Nonconforming Coke into other Coke Shipments such that (A) such Nonconforming Coke
is added onto the coke conveyor only with new, unscreened coke production, (B) such blended Coke does not exceed or, as applicable, is not less than the “reject” limits set forth in the Coke Quality Standards, (C) the ash
content, volatile matter content, sulfur content, moisture content and size of such Nonconforming Coke, are not less than *****% or do not exceed *****%, as applicable, of the “reject” limits set forth in the Coke Quality Standards and
(D) the stability of such Nonconforming Coke is not less than the “reject” limit set forth in the Coke Quality Standards. Purchaser may waive the requirements set forth in clauses (C) and (D) of this Section 5.1(b)(iv)
from time to time in its sole discretion. 
 (v) 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 Coke deliveries, and shall promptly notify Purchaser in Writing of such corrective measures. 

(c) Changes to 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 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 Coke Plants, the “threshold” or “reject” 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. 

  
 19 









 ARTICLE VI 
 OBLIGATIONS RELATED TO COKE SUPPLY AND DELIVERIES 
 6.1
[Intentionally omitted] 
 6.2 Coke Supply and Purchase Obligation. 

(a) Seller’s Supply Obligation. Subject to Section 6.6, beginning January 1, 2010 and for each subsequent Contract
Year Seller’s obligation (“Coke Supply Obligation”) in respect of the Coke Supply and Purchase Obligation is: 
 (i) as respects the Base Case Coal Blend, not less than 90% of five hundred fifty thousand (550,000) Tons of Coke or, as applicable, Third Party Supplied Coke; 

(ii) as respects each Coal Blend that contains a volatile matter content percentage which varies from the Base Case Coal
Blend, not less than 90% of the Coke and Third Party Supplied Coke Tonnage provided for in the corresponding volatile matter content percentage set forth in the attached and incorporated Schedule 6.2(a). 

(b) Purchaser’s Purchasing Obligation. Subject to Section 6.6 and Purchaser’s rejection rights in respect of
Nonconforming Coke, Purchaser’s obligation in respect of the Coke Supply and Purchase Obligation is to purchase all Coke conforming to the Coke Quality Standards produced by Seller delivered by Seller to the Coke Rail Delivery Point, not to
exceed 105% of the Purchaser’s Targeted Coke Production. 
 (c) Ratability of Coke Production. In accordance with
Prudent Operating and Maintenance Practices, but subject to Seller Force Majeure Event(s), 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 to the Coke Rail Delivery Point not less than *****% (*****%, in the case of the Contract Year commencing January 1, 2010) of the
Targeted Coke Production (the “Minimum Ratability Standard”). 
 6.3 Coke Deliveries. 

(a) Coke Delivery Points. All Coke deliveries by Seller to Purchaser shall be made at the Coke Rail Delivery Point. In the case of
such deliveries, Purchaser shall supply all railcars reasonably required to receive such Coke from Purchaser at the rail yard located at the Site. The Parties shall reasonably cooperate in scheduling such Coke 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 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 Coke Tonnage; (ii) Purchaser will reimburse Seller for Seller’s actual handling costs associated


  
 20 









 
therewith, including reasonable storage, incurred by Seller in connection with the stockpiling of such Coke Tonnage; and (iii) the moisture content of such Coke Tonnage, or any blending of
such Coke Tonnage with other Coke Tonnage performed at Purchaser’s request, shall not be required to conform to the moisture specification set forth in the Coke Quality Standards; provided, however, Seller shall not be obligated to store more
than fifteen thousand (15,000) Tons of Coke at the Coke Plants (“Stored Coke”) on behalf of the Purchaser at any point during the Term or any renewal thereof. 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 either (i) Purchaser fails to pay for
such wrongfully refused Coke Tonnage, (ii) Coke stored at the Coke Plants exceeds the allocated storage amount of fifteen thousand (15,000) Tons, or (iii) Purchaser does not remove from the Coke Plants the Stored Coke within six
(6) months of the first Coke Tonnage entering the stockpile, then in any such case Seller may resell the same upon Written notice 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), less any amount paid to Seller by Purchaser for such Coke Tonnage, between (i) the sum of (x) the product of the applicable (A) Coke Price multiplied by (B) such Coke
Tonnage, plus (y) reasonable storage and re-screening costs and degradation and handling losses in respect thereof, plus (z) any Incidental Damages in respect thereof, 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) Title and Risk
of Loss. Title and all risk of loss, damage or destruction in respect of (i) Coke Tonnage will pass to and be assumed by Purchaser upon its delivery to the Coke Delivery Point, and (ii) any Breeze purchased 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) (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 

  
 21 









 
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 the Ashland 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 or the Ashland 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 in accordance with Section 3.3(d). Notwithstanding anything to the contrary set forth in this Agreement, except as respects the occurrence of Seller Force Majeure Event(s), if Seller reasonably determines that the
Coke production capacity of the Coke Plants 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 or the Ashland 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) 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 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 January 1, 2011, 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 

  
 22 









 
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. 

(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 Coke Plants 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 Coke Plants, 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 Coke Quality Standards; (ii) the Coal Blend Standards, (iii) the Guaranteed Coke Yield Percentage; (iv) the cost of
operating or maintaining the Coke Plants (including associated capital costs); (v) the production capacity of the Coke Plants and Cogeneration Plant (including Coke and electrical 

  
 23 









 
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. 
 (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 

  
 24 









 (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 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 Coke that conforms to or approximates the 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. 

  
 25 









 (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 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 Coke
Plants). 
 (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 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


  
 26 









 
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. 
 (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 and the Related Energy Sales 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.

part of the Guaranteed Obligations shall affect, impair or be a defense to this Guaranty, and this Guaranty shall be primary, absolute and unconditional notwithstanding the occurrence of any event or the existence of any other circumstances which
might constitute a legal or equitable discharge of a surety or guarantor 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 shall any single or partial exercise of any right, power or
privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein expressly specified are cumulative and not exclusive of any rights or remedies which AK would
otherwise have. Other than the notice required to be given to Guarantors as specified in Section 2 of this Guaranty, no notice to or demand on Guarantors in any case shall entitle 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. 
 7. Guarantors waive, to the maximum extent permitted by applicable law, any right to require AK to (a) proceed against Seller or (as applicable) any other person; or (b) pursue any other of its
remedies. 
 8. Guarantors assume all responsibility for being and keeping themselves informed of Seller’s financial
condition and assets, and of all other circumstances bearing upon the risk of nonpayment or nonperformance of the Guaranteed Obligations and the nature, scope and extent of the risks which Guarantors assume and incur hereunder, and agree that AK
shall have no duty to advise Guarantors of information known to them regarding such circumstances or risks. 
 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

successors and assigns. 
 12. Neither this Guaranty nor any provision hereof may be changed, waived, discharged or terminated
except with the written consent of AK and Guarantors.

(“Guarantor”), for the benefit of Haverhill North Coke Company, a Delaware corporation (“Seller”). 

Recitals 
 A. This Guaranty is made pursuant to the Coke Purchase Agreement dated as of August 31, 2009 by and between Seller and AK Steel Corporation, a Delaware corporation (“AKS”) (“Coke
Purchase Agreement”). 
 B. This Guaranty is made for the benefit of Seller to guarantee the performance by AKS of its
obligations under the Coke Purchase Agreement (the obligations referred to herein are collectively the “Guaranteed Obligations”).

as otherwise set forth in Section 1.6 of the Coke Purchase Agreement. 
 D. Guarantor will obtain benefits from AKS
entering into the Coke Purchase Agreement and, accordingly, desires to execute this Guaranty in order to satisfy the conditions described in the preceding paragraph and to induce Seller to enter into the Coke Purchase Agreement. 

Agreements 
 NOW, THEREFORE, in consideration of the foregoing and other benefits accruing to Guarantor, the receipt and sufficiency of which are hereby acknowledged, Guarantor hereby makes the following
representations and warranties to Seller and hereby covenants to Seller as follows: 
 1. Guarantor guarantees to Seller the
full performance of all Guaranteed Obligations. Guarantor understands, agrees and confirms that Seller may enforce this Guaranty against Guarantors without first proceeding against AKS. 

2. The liability of Guarantor hereunder shall not be affected or impaired by (a) any other continuing or other guaranty, undertaking
or maximum liability of Guarantor or of any other person as to the obligations and performance of AKS; (b) any reduction of any such other guaranty or undertaking; (c) any dissolution, termination or increase, decrease or change in
personnel by AKS; (d) any payment made to Seller in respect of the Guaranteed Obligations which Seller repays to AKS pursuant to court order in any bankruptcy, reorganization, arrangement, moratorium or other debtor relief proceeding, and
Guarantor waives any right to the deferral or modification of their obligations hereunder by reason of any such proceeding; (e) any assignment by AKS of any of its rights under the Coke Purchase Agreement; or (f) the sale, transfer or

SCHEDULE 1.5 
 PAGE 1 








 3. Other than the notice required to be given to Guarantor as specified in Section 2 of
this Guaranty, Guarantor hereby waives notice of acceptance of this Guaranty and notice of any liability to which it may apply, and waives promptness, diligence, presentment, demand of payment, protest, notice of dishonor or nonpayment of any such
liabilities, suit or taking of other action by Seller against Guarantor. 
 4. Seller may at any time and from time to time

(b) settle or compromise any of the Guaranteed Obligations or any liability (including any of those hereunder) incurred
directly or indirectly in respect thereof or hereof; and/or 
 (c) consent to or waive any breach of, or any act,
omission or default under, the Coke Purchase Agreement, or otherwise amend, modify or supplement the Coke Purchase Agreement. 

5. No invalidity, irregularity or unenforceability of all or any part of the Guaranteed Obligations shall affect, impair or be a defense

entitle Guarantor to any other further notice or demand in similar or other circumstances or constitute a waiver of the rights of Seller to any other or further action in any circumstances without notice or demand. It is not necessary for Seller to
inquire into the capacity or powers of AKS 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.

 7. Guarantor waives, to the maximum extent permitted by applicable law, any right to require Seller to (a) proceed
against AKS or (as applicable) any other person; or (b) pursue any other of its remedies.

 These quality standards and price adjustments are for use on Coke with a minimum bottom coke size of
*****”. 
 Ash and Total Sulfur Shipment Standards – Each of the Shipment 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 Shipment 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 Shipment coal sample(s) result in an average ash content of
*****% and an average volatile matter content of *****%, then the Shipment standards for ash are: (Target = *****%, Quality Threshold = *****% and Reject Standard = *****%). The Shipment 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 Shipment coal sample(s) result in an average sulfur content of *****%, then the Shipment standards for sulfur are: (Target =*****%, Quality
Threshold = *****% and Reject Standard =*****%). 
 Stability Penalty and Credit – For each one (1) 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


  

SCHEDULE 5.1

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. 
 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. 
 Pro-Rata Adjustments: 
 For ash, volatile matter, sulfur and moisture, any
percentage over the threshold amount shall be pro-rated for each *****(*****) 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 ***** basis. For moisture, sulfur, ash, volatile matter and stability, and the results thereof shall be ***** on a
Shipment basis.

 Attachment A 
 Fuel Surcharge 
 In the event the average per-barrel monthly price of West Texas Intermediate
Crude Oil (the "WTI Average Price”) exceeds $***** as calculated using the daily prices published in The Wall Street Journal and as further described below, Norfolk Southern Railway Company (“NS”) will assess a fuel surcharge on all
line haul freight charges under the transportation contract C-9381 between NS and Seller for Coal delivered to the Coke Plants as set forth in this Attachment A. The applicable fuel surcharge percentage shall be applied to each shipment having a
bill of lading dated on or after the 1st day of the second calendar month following the calendar month of a given WTI Average Price calculation. The fuel surcharge will change monthly per the table below: 

 

							
	 Calendar Month of

	 May
	  	July 1	  	November	  	January 1
	 June
	  	August 1	  	December	  	February 1

 The fuel surcharge will be *****% of the line haul freight charge for every $***** per barrel, or portion thereof, by
which the WTI Average Price exceeds $*****. The WTI Average Price for a given calendar month will be determined by adding the daily West Texas Intermediate Crude Oil prices published in The Wall Street Journal during a calendar month and dividing
the result by the number of days so published in that given month. The result will be rounded to the nearest cent. If The Wall Street Journal ceases publication of the price of West Texas Intermediate Crude Oil, NS will employ a suitable substitute
source of price or measure. The following schedule reflects the applicable fuel surcharge within the WTI Average Price ranges noted below and is not exclusive.
