defined in that certain Guaranty Agreement, dated as of February 19, 1998, by and between Sun Company, Inc. (the former name of Sunoco) and DTE Indiana Harbor LLC, a Delaware limited liability company, as the beneficiary thereunder
(collectively, with the GE Guarantee, the “Indiana Harbor Guarantees”), (3) any other payment or performance obligation owed by any Person in respect of the operations, obligations, or liabilities of, or relating to, Indiana

support, as may be necessary (i) to provide such funds or to perform such obligations (a) for the benefit of the primary obligor under each Covered Obligation, or (b) if such funding or performance directly for the benefit of the
primary obligor is commercially impractical (by way of illustration and not by way of limitation, if the primary obligor is, in turn, required to deliver documents to, or perform obligations for the benefit of, a Government Authority), then on

Liabilities relating to, arising out of or resulting from such demand, payment, or performance. 
 E. For so long as any Covered
Obligations related to the Indiana Harbor Note remain to be paid or performed, SunCoke desires (i) to restrict the assets (other than additional cash capital contributions) and liabilities of Claymont, to Claymont’s assets and liabilities
existing on the date hereof, and any inter-company demand loans by Claymont to any SunCoke Group Obligor, so long as such loan is made upon arm’s length terms then prevailing between Third Parties (each, and “Arm’s Length
Loan”), (ii) to restrict Claymont’s purposes and business activities to the conduct of the business Claymont is conducting on the date hereof, and (iii) to restrict Claymont’s ability to incur any debt or other

GUARANTY, KEEP WELL FUNDING, AND INDEMNITY 
 2.01 Guaranties by the SunCoke Group Guarantors. 
 (a) Subject to
Section 3.01, the SunCoke Group Obligors hereby, jointly and severally, irrevocably and unconditionally guarantee, for the benefit of each member of the Sunoco Group, the prompt and complete payment and performance when due of each Covered
Obligation and in any event prior to the date demand is entitled to be made on any member of the Sunoco Group for the payment or performance thereof.

assistance as shall be necessary to enable each member of the SunCoke Group to pay or perform each of its Covered Obligations on or before the date the payee or other obligee in respect of such Covered Obligations would be entitled to make demand on
any member of the Sunoco Group for payment or performance in respect thereof.

 2.03 Indemnities. Subject to Section 3.01, if (i) Claymont does not pay all
or any portion of any payment that becomes due under the Indiana Harbor Note on its Payment Date, or (ii) notwithstanding the undertakings of the SunCoke Group Obligors in respect of the Keep Well Undertakings pursuant to Section 2.02, a

 (c) With respect to each SunCoke Group Obligor, no payment made by Claymont, any other primary obligor, any other SunCoke
Group Obligor, or any other Person by virtue of any action or proceeding or any set-off or appropriation or application at any time or from time to time in reduction of or in payment of the Covered Obligations shall be deemed to modify, reduce,
release or otherwise affect the liability of such SunCoke Group Obligor under the Covered Obligation Documents, and such SunCoke Group Obligor shall, notwithstanding any such payment (other than any payment made specifically in respect of a Covered
Obligation), remain liable for the payment and performance of any remaining Covered Obligations up to the Maximum Liability of such SunCoke Group Obligor until the Covered Obligations have been fully satisfied. 

3.02 Rights of Contribution. Each SunCoke Group Obligor hereby agrees that to the extent a SunCoke Group Obligor shall have paid
or be obligated to pay more than its proportionate share of any payment made in respect of the Covered Obligations, such SunCoke Group Obligor shall be entitled to contribution from and against any other SunCoke Group Obligor that has not paid its
proportionate share of such payment. Each SunCoke Group Obligor’s right of contribution shall be subject to the terms and conditions of Section 3.03. The provisions of this Section 3.02 shall in no respect limit the obligations and
liabilities of any SunCoke Group Obligor to any member of the Sunoco Group, and each SunCoke Group Obligor shall remain liable to the members of the Sunoco Group for the payment and performance of the Covered Obligations, up to such SunCoke Group
Obligor’s Maximum Liability.

renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by any member of the Sunoco Group obligated thereon, and (c) any documents executed 

  
 6 

 
and delivered in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, pursuant to the terms and conditions of each such applicable document from time to

3.05 Guarantee Absolute and Unconditional. 
 (a) Each SunCoke Group Obligor waives any and all notice of the creation, renewal, extension, amendment, or accrual of any of the Covered Obligations and notice of or proof of reliance by any member of
the Sunoco Group or any other Person upon the guarantee contained in Article II or acceptance of the guarantee contained in Article II. 
 (b) Each SunCoke Group Obligor waives diligence, presentment, protest, and demand for payment or performance, notice of intent to accelerate, notice of acceleration and notice of default, nonpayment, or
nonperformance to or upon any such SunCoke Group Obligor or any of the other SunCoke Group Obligors with respect to the Covered Obligations. Each SunCoke Group Obligor understands and agrees that the guarantee contained in Article II shall be
construed as a continuing, absolute, irrevocable and unconditional guarantee of payment and performance, and a primary obligation of each SunCoke Group Obligor, without regard to (i) the validity or enforceability or perfection of any of the
Covered Obligations or any other collateral security therefor or guarantee or right of offset with respect thereto at any time or from time to time held by, for, or on behalf of any member of the Sunoco Group, (ii) any defense, set-off or
counterclaim whatsoever (other than a defense of payment or performance) which may at any time be available to or be asserted by any SunCoke Group Obligor or any other Person against any member of the Sunoco Group, or (iii) any other
circumstance whatsoever (with or without notice to or knowledge of any SunCoke Group Obligor), other than payment or performance, which constitutes, or might be construed to constitute, an equitable or legal discharge of any SunCoke Group Obligor
for any of its respective portion of the Covered Obligations or of such SunCoke Group Obligor under the guarantees contained in Article II or any other Covered Obligation Document, in bankruptcy or in any other instance. 

(c) When making any demand hereunder or otherwise pursuing its rights and remedies hereunder against any SunCoke Group Obligor, any
member of the Sunoco Group may, but shall be under no obligation to, make a similar demand on or otherwise pursue such rights and remedies as it may have against any other SunCoke Group Obligor or any other Person for the Covered Obligations or any
right of offset with respect thereto, and any failure by any member of the Sunoco Group to make any such demand, to pursue such other rights or remedies or to collect any payments from any SunCoke Group Obligor or any other Person or to realize upon
any such collateral security or guarantee or to exercise any such right of offset, or any release of any other SunCoke Group Obligor or any other Person or any such collateral security, guarantee or right of offset, shall not relieve such SunCoke
Group Obligor of any obligation or liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of any member of the Sunoco Group against such SunCoke Group Obligor. For the
purposes of this Section 3.05, “demand” shall include the commencement and continuance of any legal proceedings. 

  
 7 

 (d) All dealings in respect of the Covered Obligations between any of the SunCoke Group
Obligors, on the one hand, and any member of the Sunoco Group, on the other hand, shall be conclusively presumed to have been had or consummated in reliance upon the guarantee contained in Article II or in any other Covered Obligation Document.

 3.06 Reinstatement. The guarantee contained in Article II shall continue to be effective, or be reinstated, as the
case may be, if at any time any payment or performance, or any part thereof, of any of the Covered Obligations is rescinded or must otherwise be restored or returned by any member of the Sunoco Group upon the insolvency, bankruptcy, dissolution,
liquidation or reorganization of any SunCoke Group Obligor as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, any SunCoke Group Obligor or any substantial part of its property, or
otherwise, all as though such payments had not been made. 
 3.07 Payments. Each SunCoke Group Obligor hereby agrees and
guarantees that all payments hereunder by such SunCoke Group Obligor will be paid without set-off or counterclaim.

 STEAM SUPPLY AND PURCHASE AGREEMENT 

This STEAM SUPPLY AND PURCHASE AGREEMENT (“Agreement”), entered into on October 19, 2010 and effective as of
January 1, 2011 (the “Effective Date”), by and between Haverhill North Coke Company, a Delaware corporation (“Haverhill”), and Sunoco, Inc. (R&M), a Pennsylvania corporation (“Sunoco”).

 BACKGROUND 
 A. Haverhill has constructed and is operating the Coke Plant (Phase I), and in connection with the operation of the Coke Plant (Phase I) will produce Steam, which Sunoco desires to purchase from
Haverhill; and 
 B. As a result of steam generation by the Coke Plant (Phase I), Boiler Blowdown Water and Drip Leg Condensate
will be taken into Sunoco’s steam system and will be managed by Sunoco; and 
 C. Haverhill desires Boiler Feed Water for
its use at the Coke Plant (Phase I) and River Water for its use at the Coke Plant, and Sunoco desires to make such Boiler Feed Water, River Water available to Haverhill; and 
 D. Haverhill desires to use Natural Gas to create additional heat in the steam generation system of the Coke Plant (Phase I) through Sparging, and to obtain an additional amount of Natural Gas to support
its on-going Coke Plant operations, and Sunoco desires to supply Natural Gas to Haverhill for these purposes; and 
 E. Sunoco
desires to secure a low cost, ratable and reliable supply of Steam and to minimize the operation of the existing boilers at the Chemical Plant; and 
 F. Sunoco has contributed twelve million eight hundred thousand dollars ($12,800,000.00) in capital to the construction of the Steam conveyance and excess Steam condensing facilities at the Chemical
Plant; and 
 G. Haverhill has spent approximately one hundred forty five million dollars ($145,000,000) in capital (net of the
contribution by Sunoco) to develop the Coke Plant (Phase I) based upon ratable returns in respect of coke and Steam sales. 

NOW, THEREFORE, in consideration of the mutual covenants herein contained and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, Haverhill and Sunoco agree as follows: 

 ARTICLE 1

 ARTICLE 3 
 STEAM SUPPLY 
 3.1 Steam Obligations. During the Term of this
Agreement, except for twelve thousand (12,000) pounds per hour which Haverhill currently uses for soot blowing at the Coke Plant, Haverhill shall deliver all of the Steam produced at the Coke Plant (Phase I) to Sunoco at the Steam Delivery
Point and Sunoco shall take delivery of and either consume or condense all such Steam. Notwithstanding the foregoing, if to the extent that the Steam Condensing Facilities reach their capacity, the Parties agree to work together to address how to
process the Steam in excess of the limits of the Steam Condensing Facilities. Notwithstanding the foregoing, nothing in this Agreement shall restrict Sunoco from producing or procuring steam for any purpose, in any amount or quality from its own
facilities or from any third party, in excess of the Maximum Steam Supply Obligation or as necessary to supplement Steam provided by Haverhill under this Agreement. 

  
 - 10 -

 3.2 Monthly Nomination. By providing Haverhill Written notice
thereof on or before the fifteenth (15th) Business
Days of each Month, Sunoco shall nominate the amount of Steam between the Anticipated Minimum Steam Amount and the Maximum Steam Supply Obligation it desires to source from Haverhill for its production process in the upcoming Month (the
“Nominated Steam Amount”). For the avoidance of doubt, the Nominated Steam Amount shall include the Steam necessary for Sunoco to operate the Steam Condensing Facilities. If Haverhill reasonably believes it will be unable to provide
the Nominated Steam Amount, Haverhill shall notify Sunoco within five (5) Business Days of receipt of Sunoco’s nomination. Such notification will set forth the amount of Steam Haverhill reasonably believes it will be able to provide during
the upcoming Month; provided, that such notification shall be for operational purposes only and any Steam Delivery Shortfalls shall be calculated based upon the Nominated Steam Amount. 

3.3 Excess Steam. The Parties acknowledge that as a result of the production process at the Coke Plant (Phase I), in some cases
Haverhill will produce and deliver Steam in excess of the Nominated Steam Amount (“Excess Steam”) and Sunoco shall either consume or condense (subject to Section 3.13) such Excess Steam. 

3.4 Sparging. If Sunoco desires additional Steam in excess of the Nominated Steam Amount and any Excess Steam then being
delivered, Sunoco may request that Haverhill Sparge in order to produce additional Steam. If Haverhill elects to Sparge at such request, then Haverhill shall not be obligated to pay for the Natural Gas used in Sparging to produce such additional
Steam and such additional Steam shall be delivered to Sunoco at no cost based upon the Sparging Efficiency Factor. The additional Steam produced by Sparging in accordance with this Section (“Sparging Generated Steam”) will be
calculated using the following formula (in thousands of pounds): 
  

					
	Sparging Generated Steam	  	=	  	the decatherms of Natural Gas used in Sparging in accordance with Section 3.4 * the Sparging Efficiency Factor

The Parties shall cooperate to improve Sparging efficiency; provided, that any material expenditure of capital or cost for such improvements shall
be borne by the Parties based upon the allocation of the received benefit of such improvements (subject to the agreement of the Parties). To reflect improvement to the Sparging efficiency, the Parties shall, periodically, update the Sparging
Efficiency Factor by mutual Written agreement. 
 3.5 Supplemental Steam. If, as a result of improvements at the Coke
Plant (Phase I), Haverhill is able to consistently produce Steam in excess of the Maximum Steam Supply Obligation (“Supplemental Steam”), Haverhill shall, before using such Supplemental Steam for other purposes, offer such
Supplemental Steam to Sunoco for use at the Chemical Plant. Such offer shall be in Writing and set forth the amount of Supplemental Steam available. Sunoco shall have thirty (30) days in which to review and accept the offer in Writing to
Haverhill. If Sunoco fails to respond in Writing within such thirty (30) day period, the offer shall be deemed to have been rejected and Haverhill may use such Supplemental Steam for such other purposes as its sees fit. If Sunoco accepts the
offer, the Parties shall amend this Agreement in Writing to (a) increase the Maximum Steam Supply Obligation by the amount of Supplemental Steam available, (b)

  
 - 11 -

 
increase the Steam Capacity Reservation Fee by an amount representing the value of the Supplemental Steam provided on an annual basis and (c) increase the point at which the Steam Delivery
Shortfall Penalty Amount is applied. In no event shall Haverhill be obligated to provide the Supplemental Steam until such time as the Parties have executed the requisite amendment to this Agreement. If the Parties are unable to agree in good faith
to an amendment to this Agreement within sixty (60) days of Haverhill’s initial offer of the Supplemental Steam, such offer shall be deemed rejected and Haverhill may use such Supplemental Steam for such other purposes as its sees fit. In
the event that Sunoco rejects the Supplemental Steam, Haverhill’s right to use such Supplemental Steam for other purposes shall be subject to the requirement that Haverhill return steam condensate resulting from the use of such Supplemental
Steam to Sunoco. 
 3.6 Steam Specifications. All Steam supplied hereunder shall conform to the following specifications
(the “Steam Specifications”): 
 (a) Pressure and Temperature. Because Sunoco controls certain
variables which directly impact steam pressure and temperature, including feed water pressure, feed water temperature, load (steam flow rate), and the condensing station operation, Haverhill cannot be held unilaterally responsible for the pressure
or temperature of the Steam delivered under this Agreement. However, Haverhill acknowledges that its HRSGs are designed to provide steam at four hundred sixty (460) PSIG and produce Steam at saturation temperature. To the extent that Steam
pressure or temperature fall outside the reasonably optimal range for the operation of the Chemical Plant and the Coke Plant (Phase I), the Parties shall cooperate and take all such commercially reasonable steps necessary to reasonably optimize
Steam pressure and/or temperature; provided, however, that in no event shall such commercially reasonable steps include the incurrence of a capital expense or materially increase the cost of operating the Chemicals Plant or the Coke Plant
(Phase I) without corresponding economic adjustments to this Agreement which would require the consent of both Parties. 
 (b)
Purity. Subject to the provision by Sunoco of Boiler Feed Water which meets the Boiler Feed Water Standards, Haverhill shall provide a maximum 0.5 PPM sodium carryover at each HRSG. 

3.7 Maintenance Scheduling. 
 (a) Annual Maintenance. Not less than sixty (60) days prior to the commencement of each calendar year, Sunoco will provide Haverhill an expected schedule for Steam demand based on scheduled
maintenance and other conditions at the Chemical Plant for the coming calendar year (the “Annual Steam Plan”). The Parties shall use commercially reasonable efforts to coordinate Sunoco’s scheduled Steam demand (as provided for
in Section 3.2), with Haverhill’s scheduled maintenance of its HRSGs. Notwithstanding anything to the contrary contained in this Section, the Parties agree that total scheduled HRSG maintenance for all HRSGs shall not exceed twenty five
(25) calendar days’ time during any single calendar year. 
 (b) Planned Total Steam Outage. During the
Initial Term and periodically thereafter, approximately once every three years, during any Renewal Term, Haverhill will be required to shut down all of its HRSGs in order to upgrade, in the first instance,

  
 - 12 -

 
and maintain, thereafter, the FGD system at the Coke Plant (Phase I) (each a “Planned Total Steam Outage”). Haverhill shall use commercially reasonable efforts to keep any such
Planned Total Steam Outage under ten (10) calendar days. Scheduling of any Planned Total Steam Outage will be set forth in Haverhill’s annual maintenance planning and coordinated with scheduled maintenance at the Chemical Plant. During a
Planned Total Steam Outage, no Steam Delivery Shortfall Penalty shall apply and the Sunoco’s sole remedy shall be a reduction in the Steam Capacity Reservation Fee equal to twenty eight thousand dollars ($28,000) per day of the Planned Total
Steam Outage. 
 3.7.4 Cooperation. Notwithstanding the Nominated Steam Amount, the Parties shall use reasonable efforts
to balance daily and hourly Steam supply and demand and to accommodate unexpected and unscheduled operations and conditions. To this end, in the event of a Chemical Plant Disruption or a Force Majeure Event, Haverhill shall Sparge when requested to
do so by Sunoco in order to support the safe and reliable operation of the Chemical Plant. 
 3.8 Measurement Instruments.

 3.8.1 Steam Monitor Instruments. Haverhill has installed, at its cost, (i) two (2) meters to measure
Steam flow at the existing pressure transmitters located as shown on Exhibit A, on the west side of the Sunoco boiler area steam header (each, a “Steam Flow Meter” and collectively, the “Steam Flow Meters”)
and (ii) an instrument to measure Steam pressure located near the Steam Flow Meters (the “Steam Pressure Instrument”) and (ii) an instrument to measure Steam temperature each located near the Steam Flow Meters (the
“Steam Temperature Instrument”). The Steam Flow Meters shall continuously measure the flow of Steam delivered from the Coke Plant (Phase I) to the Chemical Plant. The Steam Pressure Instrument and the Steam Temperature Instrument
shall continuously measure the pressure and temperature of Steam delivered from the Coke Plant (Phase I) to the Chemical Plant. The Steam Flow Meters shall be calibrated to measure steam flow to an accuracy of not less than plus or minus two percent
(+/- 2%). The Steam Pressure Instrument shall be calibrated to measure steam pressure to an accuracy of not less than plus or minus one percent (+/- 1%). The Steam Temperature Instruments shall be calibrated to measure steam temperature to
an accuracy of not less than plus or minus five degrees Fahrenheit (+/- 5o F.). The Parties acknowledge that Haverhill has installed the required Steam Monitor Instruments. 

3.8.2 Excess Steam Condensate Instruments. Haverhill shall install, at its cost, (i) a flow meter on the Excess Steam
Condensate Return Line (the “Excess Steam Condensate Flow Meter”), and (ii) a temperature instrument on the Excess Steam Condensate Return Line (the “Excess Steam Condensate Temperature Instrument”), as shown
on Exhibit A (each an “Excess Steam Condensate Instrument” and collectively, the “Excess Steam Condensate Instruments”). The Excess Steam Condensate Instruments shall continuously measure the flow and
temperature of the condensed excess steam in the Excess Steam Condensate Return Line. The Excess Steam Condensate Flow Meter shall be calibrated to plus or minus two percent (+/- 2%). The Excess Condensate Temperature Instrument shall measure
condensate temperature to accuracy of not less than plus or minus five degrees Fahrenheit (+/- 5o F.). The Parties acknowledge that Haverhill has installed the required Excess Steam Condensate Instruments.

 3.9 Steam Calculations. 

3.9.1 Steam Consumption Calculations. When both Steam Flow Meters are operable, the average reading of the Steam Flow Meters shall
be used to determine the quantity of Steam delivered to Sunoco from Haverhill (in thousands of pounds). This average reading shall be established as follows: 
 (a) each hour, the average of the two Steam Flow Meters (adjusted for pressure and temperature) will be calculated by the Sunoco computer system (the “One Hour Average Steam Mass
Reading”); and 
 (b) each day all of the One Hour Average Steam Mass Readings for such day shall be totaled (the
“Daily Steam Consumption Quantity”); and 
 (c) Each Month, all of the Daily Steam Consumption Quantities
occurring during such Month will be added together and that total, less the Excess Steam Condensate Return Credit, shall equal the quantity of Steam consumed by Sunoco for such Month (the “Monthly Steam Consumption Quantity”).

 3.9.2 Steam Delivery Calculations. 
 (a) For determining whether there has been a Steam Delivery Shortfall, Steam delivered on an hourly basis shall be calculated based upon the One Hour Average Steam Mass Reading plus the quantity of Steam
(in thousands of pounds per hour) condensed that hour by the Steam Condensing Facilities calculated pursuant to Section 3.9.3 (the “Steam Delivered (Hourly)”). 

(b) For determining whether a Steam Delivery Shortfall Penalty has occurred on any given day, Steam delivered on a daily basis shall be
calculated based upon the daily average of each day’s One Hour Average Steam Mass Readings plus the average quantity of Steam (in thousands of pounds per hour) condensed that day by the Steam Condensing Facilities calculated pursuant to
Section 3.9.3 (the “Steam Delivered (Daily Average)”). 
 (c) For the avoidance of doubt, the Excess Steam
Condensate Return Credit has no application in the determination of a Steam Delivery Shortfall or a Steam Delivery Shortfall Penalty. 
 3.9.3 Steam Condensing Calculations. 
 The steam condensing flow is
determined using the three valve positions in relation to the control valve flow curves. The Parties shall cooperate to make this calculation as accurate as possible or otherwise improve the measurement of Steam Condensed by the Steam Condensing
Equipment. No more than twice a Contract Year, at the request of Haverhill, Sunoco shall provide the supporting documentation necessary to validate the calculation. 

  
 - 14 -

 3.10 Steam Monitor Instrument Failure. 

3.10.1 Failure of One Steam Flow Meter. If only one Steam Flow Meter is operable, then the average one hour reading for that meter
shall be established as follows: each hour, the average flow of the operating Steam Flow Meter (adjusted for pressure and temperature) will be calculated by the Sunoco Computer System (the “One Meter One Hour Average Steam Mass
Reading”). For the period of time only one Steam Flow Meter is operable, this One Meter One Hour Average Steam Mass Reading will be substituted for the One Hour Average Steam Mass Reading to determine the Steam consumption in accordance
with Section 3.9.1. 
 3.10.2 Failure of Both Steam Flow Meters. If both Steam Flow Meters are inoperable, then the
quantity of Steam delivered during such occurrence shall be deemed to be the product of (i) the average pounds of Steam (measured in thousands of pounds) delivered per hour for the twenty four (24) hour period that immediately precedes
such occurrence, adjusted for any known changes in Sunoco’s Steam consumption, and during which all of the heat recovery steam generators within the Coke Plant (Phase I) were continuously operating and (ii) the duration in hours (rounded
to the nearest minute) of such failure. 
 3.10.3 Inaccuracy of Steam Flow Meters. If the two Steam Flow Meters are not
measuring Steam to within an accuracy of 5% or less of each other, then Sunoco will in good faith and in accordance with Prudent Chemical Plant Practice identify which Steam Flow Meter most closely tracks the One Hour Average Steam Mass Reading
during recent periods of similar Steam demand, and the One Meter One Hour Average Steam Mass Reading for such Steam Flow Meter will be substituted for the One Hour Average Steam Mass Reading to determine the Steam consumption in accordance with
Section 3.9.1 for the time period during which the 5% or greater inaccuracy occurs. 
 3.11 Maintenance and Calibration.

 3.12 Steam Delivery Shortfalls. Except to the extent caused by a Chemical Plant
Disruption or a Force Majeure Event, if Haverhill fails to deliver the Nominated Steam Amount to the Steam Delivery Point (based upon the One Hour Average Steam Mass Reading) a steam delivery shortfall shall have been deemed to have occurred (each a
“Steam Delivery Shortfall”). The occurrence of a Steam Delivery Shortfall shall result in a one-time reduction of the Steam Capacity Reservation Fee for the given year equal to the Steam Shortfall Cost of such Steam Delivery
Shortfall. In addition, if Steam delivered during any Steam Delivery Shortfall is below the Steam Delivery Shortfall Penalty Threshold (based upon the Steam Delivered (Daily Average)), Haverhill will incur an additional penalty (each a
“Steam Delivery Shortfall Penalty”) equal to the Steam Delivery Shortfall Penalty Amount, which shall be offset amounts due for Steam under this Agreement. Except as specifically set forth in Section 10.1.1, the foregoing shall
be Sunoco’s sole remedy for Haverhill’s failure to provide the Nominated Steam Amount under this Agreement. 
 3.13
Steam Condensing Facilities. Sunoco shall condense using the Steam Condensing Facilities any Steam delivered by Haverhill not otherwise consumed in the manufacturing process of the Chemical Plant subject to the capacity of the Steam Condensing
Facilities which can only condense up to two hundred twenty five thousand pounds (225,000) of steam per hour. Sunoco will return the output of such condensing to Haverhill as Boiler Feed Water. 

3.14 Drip Leg Condensate and Boiler Blowdown Water. Sunoco shall manage all Drip Leg Condensate and Boiler Blowdown Water.

 4.1 Haverhill Meter Installation, Calibration,
Maintenance and Repair Obligations. Haverhill shall install, maintain and, as applicable, replace at its sole cost and expense, the water meters that measure Boiler Feed Water and River Water as shown on Exhibit A (each, a “Water
Meter”). Each such Water Meter shall be calibrated (i) in accordance with the frequency recommended by its manufacturer or, if no manufacturer’s recommendation exists, then at the frequency established by accepted industry
standards; and (ii) in any event not less than once per year. All measurements under this Section shall be made available by Haverhill to Sunoco in a manner and at intervals reasonably acceptable to the Parties. Haverhill will inform Sunoco no
less than twenty-four (24) hours prior to the time of any calibrations so that Sunoco Representatives may witness the calibrations. If, upon calibration, any Water Meter is found to be inaccurate or to be in error, then that Water Meter shall
be promptly adjusted to record measurements correctly. Absent Manifest Error, but subject to the foregoing, such measurements shall be binding and conclusive on the Parties. The Parties acknowledge that Haverhill has installed each of the required
Water Meters. 
 4.2 Other Water Equipment. Sunoco shall install, maintain and, as applicable, replace at its sole cost
and expense the water lines and related equipment located on the Chemical Plant, as shown on Exhibit A, that are utilized to deliver, as applicable, Boiler Feed Water and River Water from the Chemical Plant to the Coke Plant. Haverhill shall
install, maintain and, as applicable, replace at its sole cost and expense the water lines and related 

  
 - 17 -

4.3.1 Boiler Feed Water. Solely for use at the Coke Plant (Phase I), Sunoco shall make Boiler Feed Water which consistently meets
the Boiler Feed Water Standards (Current) available to Haverhill at the Boiler Feed Water Delivery Point; provided, however, that occasional failures to meet the Boiler Feed Water Standards (Current) shall not be an event of default under
this Agreement so long as Sunoco is operating in accordance with Prudent Chemical Plant Practice and working to bring the Boiler Feed Water back into compliance. The Parties agree to cooperate to improve the Boiler Feed Water so that the Boiler Feed
Water provided under this Section shall meet the Boiler Feed Water Standards (Target), or such other standards agreed upon by the Parties; provided, that any material expenditure of capital or cost for improvements to the Boiler Feed Water
shall be shared between the Parties based upon the allocation of the received benefit of such improvements (subject to the agreement of the Parties). To reflect improvement to the Boiler Feed Water, the Parties shall, periodically, implement new
Boiler Feed Water Specifications by mutual Written agreement. Boiler Feed Water shall be provided at a flow rate nominally between eight hundred twenty five (825) GPM and one thousand fifty (1050) GPM, with a target average of nine hundred
thirty (930) GPM. Any changes by Haverhill in process piping that could impact the flow rate must be approved in advance by Sunoco in Writing. 
 4.3.2 River Water. Solely for use at the Coke Plant, Sunoco shall make River Water available to Haverhill at the River Water Delivery Point. River Water shall be provided at a flow rate of
nominally between two hundred fifty (250) GPM and nine hundred thirty (930) GPM, with a daily average flow rate not to exceed four hundred eighty (480) GPM, unless approved by Sunoco. Any changes by Haverhill in process piping at the
Coke Plant that could impact the flow rate must be approved in advance by Sunoco in Writing. In the event of an outage of the River Water supplied by Sunoco, Haverhill has installed a backup system to provide water to the Coke Plant.

by Sunoco under the Water Registration and that the availability of Boiler Feed Water and River Water is subject to the Water Registration. Haverhill shall report to Sunoco the amount of River Water used each Month no later than the fifteenth day of
the subsequent Month. In the event that the total consumption of water by Sunoco and Haverhill exceeds the total amount of water that can be obtained in accordance with the Water Registration, Haverhill shall reduce its water intake to allow Sunoco
to be in compliance with the Water Registration. In no event shall Haverhill’s consumption of River Water exceed a maximum of 930 GPM, or a daily average of 480 GPM per day, without the prior approval of Sunoco. If any Governmental Authority
shall require Haverhill to obtain a separate permit for water, the Parties shall negotiate in good faith appropriate amendments to the 

  
 - 18 -

 
water delivery requirements under this Article, provided, however, that Haverhill shall not seek any reduction in Sunoco’s rights to obtain water in applying for its own water
registration or permit. 
 4.5 Water Treatment. Sunoco will contract and pay for water treatment services for the Boiler
Feed Water and Boiler Blowdown Water, and Sunoco shall be responsible for the purchase of water treatment chemicals reasonably necessary for such services. Each Party shall add and manage the addition of water treatment chemicals to its equipment as
recommended by the water treatment service provider at its own expense. Without limiting the foregoing, Sunoco shall install and maintain amine feed and storage equipment at the Chemical Plant at Sunoco’s expense, and shall add amines as

 13.13
Intention of the Parties. 
 13.13.1 Declarations of the Parties. Sunoco’s intention in entering into this
Agreement is to secure an uninterrupted supply of Steam at a cost favorable to the market cost of Steam. In reliance on this Agreement, Sunoco has decommissioned its boilers and made a significant capital investment in condensing facilities and
facilities for the supply of services to the Coke Plant and will be operating these condensing and service facilities for the Coke Plant (Phase I). Haverhill’s intention in entering into this Agreement is to (i) secure the ratable sale of
Steam at a predictable price to a credit worthy customer, in order that Haverhill can realize a reasonable rate of return on its substantial investment, and (ii) substantially reduce its operating costs. In reliance on this Agreement, Haverhill
has developed the Coke Plant (Phase I) at a substantial cost of capital, has integrated the operations of the Coke Plant (Phase I) and the Chemical Plant in such a manner that the Chemical Plant operations are vital to the operation of the Coke
Plant (Phase I) (including, without limitation, compliance with the operating permit for the Coke Plant (Phase I)), and has priced coke sales to third parties based upon Sunoco’s estimates of Steam consumption based upon the Contract Price for
such Steam. 
 13.13.2 Integration in Respect of this Agreement. These declarations of the Parties set forth in
Section 13.13.1 are expressly subject to Section 13.7. Accordingly, they are not intended to expand the rights or obligations of the Parties under this Agreement or otherwise, and in the event of any conflict, inconsistency or ambiguity in
respect of such declarations and the remainder of this Agreement, the remainder of the Agreement shall prevail. 
 13.14
Counterparts. This Agreement may be executed in one or more counterparts and by the different Parties hereto on separate counterparts, each of which when so executed and delivered shall be an original, that all of which shall together constitute
one and same instrument.
