projection of the total quantity of each type of Feedstock (in Gallons) that it will require Seller to sell and make available during such Contract Year at each Plant (the “Annual Planned Requirements”); provided that the
Annual Planned Requirements for the first Contract Year shall equal Buyer’s forecasted aggregate requirements of Feedstock (in Gallons) for such Contract Year beginning on the Effective Date and ending December 31, 2014. The Annual Planned
Requirements shall: 

  

	 	(a)	identify applicable quantities of Ethane and Propane that are, in Buyer’s good faith determination, required at the Calvert City Plant and at the Lake Charles Plants for Buyer to produce the Annual Planned
Production of Ethylene during such Contract Year; 

  

	 	(b)	be based on Buyer’s then-current budget for each Plant; and

 ARTICLE IV 

PURCHASE AND DELIVERY OBLIGATIONS 
  

	4.1	Purchase and Take Commitments. 

  

	 	(a)	Commencing with the Effective Date, and continuing throughout the Term, subject in each case to the terms and conditions of this Agreement, Seller shall sell and make available, and Buyer shall purchase, take delivery
of and accept at the applicable Receipt Points, during each Contract Year, the quantity of the Annual Planned Requirements notified to Seller under Section 3.1 in respect of the relevant Contract Year (as adjusted pursuant to this
Section 4.1, the “Annual Quantity”), not to exceed a quantity of Feedstock necessary to produce 3.8 billion pounds of Ethylene in a given Contract Year. Buyer shall use commercially reasonable efforts to purchase,
take delivery of, and accept the Annual Quantity during each Contract Year on a ratable Monthly basis. 

  

	 	(b)	Notwithstanding anything contained herein to the contrary, Buyer shall be entitled from time to time during the Term, by prior notice, to adjust the Annual Quantity upward or downward if it determines, in its reasonable
discretion, that any such adjustment is appropriate in order to (i) account for operating conditions or marketing conditions or (ii) source from other suppliers all or a part of the Feedstock required to sell approximately 5% of the
aggregate quantities of Ethylene actually produced at the Plants during such Contract Year to Third Parties. 

  

	 	(c)	The Annual Quantity for the Contract Year in which the Term commences and ends, respectively, shall be proportionately reduced based on the number of Days during such Contract Year that occur during the Term, if
applicable. 

  

	 	(d)	Seller shall use commercially reasonable efforts to deliver the Feedstock mix notified to Seller under Section 3.1. The Parties shall consult with one another from time to time during the Contract Year and
use commercially reasonable efforts to achieve an economically optimal Feedstock mix for the operation of the Plants, as determined by Buyer in good faith. 

  

	4.2	Seller Deficiency. 

  

	 	(a)	If the total quantity of Feedstock sold and delivered by Seller under this Agreement during any Contract Year (in Gallons) is less than 


 

	 	(i)	the applicable Annual Quantity, minus 


  
 7 










	 	(ii)	the quantities (in Gallons) made available by Seller but not purchased and taken by Buyer during such Contract Year due to either 

  

	 	(A)	Buyer’s breach of its obligations hereunder or 

  

	 	(B)	Force Majeure affecting the Plants to the extent that any such occurrence exceeds 45 consecutive Days, 


then such deficiency (in Gallons) shall be the “Seller Deficiency Quantity.” 

 

	 	(b)	For the avoidance of doubt, the Seller Deficiency Quantity shall not be reduced by any quantity of Feedstock not made available by Seller due to 


 

	 	(i)	Seller’s breach of any of its obligations hereunder, or 

  

	 	(ii)	Force Majeure affecting the Plants to the extent that any such occurrence does not exceed 45 consecutive Days; or 

  

	 	(iii)	Force Majeure affecting Seller. 

  

	 	(c)	If, in respect of any Contract Year, there is a Seller Deficiency Quantity, Seller shall pay Buyer a deficiency fee ($) (the “Feedstock Shortfall Fee”) equal to the quantity of Ethylene (in pounds)
that Buyer was unable to produce and deliver from the Plants as a result of the Seller Deficiency Quantity multiplied by the sum of: 

  

	 	(i)	$0.10/lb plus 

  

	 	(ii)	the then-current All Other Cash Production Costs ($/lb), plus 

  

	 	(iii)	the then-current Prior Year Adjustment ($), if any, divided by the Annual Planned Production of Ethylene (expressed in pounds) for such Contract Year; 


provided, however, Buyer shall rebate to Seller the Variable Cash Conversion Costs and the Cost of Feedstock (each as defined in the
Ethylene Sales Agreement) that are actually avoided by Buyer for such Contract Year, if any, as a result of such deficiency, such rebate to be by way of credit in the invoice for the last Month of the Contract Year. 

 

	 	(d)	If at any time the Feedstock Shortfall Fee and the Ethylene Shortfall Fee may be applied to the same volume of Ethylene not produced or purchased, then with respect to only such volume of Ethylene contemplated by this
Section 4.2(d): 

  

	 	(i)	Downstream Buyer shall pay the applicable Ethylene Shortfall Fee in accordance with Section 4.2(c) of the Ethylene Sales Agreement and 


  
 8 










	 	(ii)	Seller shall have no obligation to pay the applicable Feedstock Shortfall Fee hereunder, 

 it
being understood and agreed that the Ethylene Shortfall Fee and the Feedstock Shortfall Fee shall not be applied in respect of the same volume of Ethylene not produced or delivered. 

 

	4.3	Uniformity. Seller shall make available and Buyer shall receive and take quantities of Feedstock hereunder at each Receipt Point, as nearly as practicable, at uniform hourly and daily rates of flow for the
quantities of Feedstock purchased hereunder. 

  

	4.4	Title, Transfer and Possession. 

  

	 	(a)	Title to and risk of loss of the Feedstock delivered hereunder shall pass from Seller to Buyer at the applicable Receipt Point free and clear of all liens, claims and encumbrances. 


 

	 	(b)	Seller shall be deemed to be in exclusive control and possession of the Feedstock deliverable to Buyer hereunder prior to the time such Feedstock shall have been delivered to Buyer at the applicable Receipt Point, and
Buyer shall be deemed to be in exclusive control and possession thereof after such delivery. 

  

	 	(c)	Seller shall bear all costs of any nature concerning the Feedstock before delivery to each applicable Receipt Point, including all applicable taxes payable by Seller in accordance with Article XVI. Buyer
shall bear all costs of any nature concerning the Feedstock at or after delivery to each applicable Receipt Point, including all applicable taxes payable by Buyer in accordance with Article XVI. 


ARTICLE V 
 PRICE

  

	5.1	Price. Commencing with the Effective Date and continuing for each Month of the Term, Buyer shall reimburse Seller for (a) the purchase of Feedstock for sale under this Agreement at a deemed purchase price
equal to the OPIS Index, plus (b) all commercially reasonable and verifiable costs incurred (excluding internal costs of Seller) for the storage, handling, and transportation of such quantities from the Mont Belvieu pricing point to the
applicable Receipt Points. Seller will use commercially reasonable efforts to minimize such costs. 

  

	5.2	Index. 

  

	 	(a)	“OPIS Index” means the monthly average of the daily high and low prices per Gallon, for the month of delivery, as quoted by Oil Price Information Service, or its successor-in-interest, in the OPIS LPG
Report for “Any Current Month” under “Mont Belvieu Spot Gas Liquids Prices” using (i) the Purity Ethane prices for Ethane (“Ethane Price”), and (ii) the “Non-TET” prices for Propane
(“Propane Price”). 


  
 9 










	 	(b)	If, for any given Month, the Ethane Price or the Propane Price fails to settle or be published prior to invoicing hereunder, the provisional price therefor shall be the Ethane Price or the Propane Price (as applicable)
for the immediately preceding Month or the last settled Month of delivery, as the case may be. Once the Ethane Price or the Propane Price (as applicable) has settled for the Month of delivery or is otherwise published, Seller will promptly
reissue the invoice for the Month in question, which invoice will provide the appropriate adjustment to reflect the change to the provisional price. Any additional amounts owing by Buyer will be paid within 15 Days of the receipt of such
invoice and any credits owing to Buyer will be applied to the next invoice delivered by Seller. 

  

	 	(c)	Should the OPIS Index be discontinued, it will be replaced by the index specified by the applicable publisher to be the replacement index therefor, or, if no replacement index is specified by the applicable publisher,
the Parties shall promptly and in good faith attempt to mutually agree to a satisfactory and comparable successor index or publication. 


ARTICLE VI 
 STATEMENTS
AND PAYMENT 
  

	6.1	Monthly Statements. On or before the 20th Day of each Month, Seller shall provide to Buyer a statement for each of the Receipt Points setting forth Seller’s calculation of the total amount payable by Buyer
for the prior Month for deliveries made to each Receipt Point (each, a “Monthly Statement”). The Parties shall provide for the exchange of all relevant data reasonably necessary in connection with preparing each Monthly Statement,
including the aggregate quantities (in Gallons) of each Feedstock delivered by Seller and taken by Buyer for each Day of such Month at each Receipt Point, information relating to any Seller Deficiency Quantity for such Month at each Receipt Point
(if applicable), and information relating to any events of Force Majeure. 

  

	6.2	Payment. 

  

	 	(a)	Buyer shall pay the amount of each Monthly Statement, other than any amount thereof that is disputed in accordance with clause (d) below, no later than the 5th Day following receipt by Buyer of such Monthly
Statement. If the due date for payment is not a Business Day, then the due date for payment shall be the immediately succeeding Business Day. Any adjustments necessary to reconcile the resolution of a disputed amount with the amount actually paid
shall be paid within five Days following resolution of the disputed amount. Any adjustments, whether for overpayment or underpayment, for disputed amounts shall bear interest at the Base Rate from the date of overpayment or underpayment, as the case
may be, until the actual date of payment. 

  

	 	(b)	In the event that any amount reflected in any statement or invoice is not paid when due, other than any amount thereof that is disputed in accordance with clause (d) below, such unpaid amount shall bear
interest from and including the Day following the due date therefor up to and including the date when payment is made, at the Default Rate. 


  
 10 










	 	(c)	If Buyer fails to make payment of any amount of any Monthly Statement, other than any amount thereof that is disputed in accordance with clause (d) below, on or before the later of (i) the 60th Day
after such payment is due and (ii) the 30th Day after notice by Seller of such non-payment, Seller shall have the right to suspend deliveries of Feedstock hereunder to Buyer until such payment is made. 


 

	 	(d)	Seller and Buyer, as the case may be, may withhold payment of all or any portion of any amount reflected as owing by such Party in any statement or invoice received from the other Party to the extent that the receiving
Party disputes payment of such amount or such portion thereof in good faith. For the avoidance of doubt, as to any Monthly Statement, Buyer may withhold payment as to any disputed amount, including to account for any credit Buyer believes it is owed
with respect to the purchase, sale or delivery of Feedstock, or the failure thereof. In the event of such a dispute, the disputing Party shall promptly notify the other Party, stating its reason for disputing such amount and, to the extent
available, providing reasonable supporting documentation therefor. 

  

	 	(e)	Buyer may dispute a Monthly Statement or any portion thereof, by notice to Seller, up to one calendar year following receipt of such Monthly Statement; provided that if Buyer fails to deliver such notification
within such period, Buyer shall be deemed to have waived the right to dispute the applicable Monthly Statement. 

  

	6.3	Payment Method. All payments under this Agreement shall be made in United States dollars by wire transfer in immediately available funds by deposit to the bank account designated in writing by the Party receiving
the payment. Any wire transfer charges shall be for the account of the Party making the payment. If a Party elects to change the bank or account to which payments are to be made, that Party shall notify the other Party before the effective date of
such change. 

  

	6.4	Access to Books and Records. To the extent necessary to verify the accuracy of any statement, invoice, charge or computation made under this Agreement, each Party shall have the right, at its cost, to interview
representatives of the other Party and to examine the books and records of the other Party relating to this Agreement during normal business hours and upon reasonable notice to the other Party; provided that each Party has the right to redact
from the records subject to examination any portions thereof as necessary to comply with such Party’s confidentiality obligations. Such examination must be commenced within 12 Months of receiving said statement, invoice, charge or computation
made under this Agreement and will take place at a location mutually agreeable to the Parties. All records subject to examination hereunder shall be caused to be retained for no less than two calendar years after their creation. If any such
examination establishes any inaccuracy in any billing made prior to such examination, the necessary adjustments to such billings will be made promptly without any interest charge. 


  
 11 










	6.5	Adequate Assurance of Performance. 

  

	 	(a)	If Seller, in its sole judgment, has reasonable grounds for insecurity regarding the ability of Buyer to perform its financial obligations hereunder, or any other material obligation under this Agreement, the
Parties shall work together in good faith to resolve Seller’s concerns. If the Parties cannot resolve such concerns, Seller may request that Buyer provide Adequate Assurance of Performance (as defined below) and if Buyer fails to provide
such Adequate Assurance of Performance within five Business Days of receipt of request therefor, Seller may, without waiving any other rights or remedies available to it under this Agreement or now or hereafter existing at Law or in equity, withhold
further deliveries until the demanded Adequate Assurance of Performance is received. 

  

	 	(b)	Buyer’s duty to provide such Adequate Assurance of Performance, if demanded in accordance herewith, shall be a condition precedent to Seller’s obligation to perform under this Agreement. 


 

	 	(c)	As of the Effective Date, Seller acknowledges that it is satisfied with Buyer’s ability to perform its obligations under this Agreement and therefore, as of the Effective Date, no Adequate Assurance of Performance
is required from Buyer. 

  

	 	(d)	“Adequate Assurance of Performance” shall mean sufficient security or proof of Buyer’s capability to perform its obligations under this Agreement in the form of any one of or a combination of one
or more of the following: (i) a guarantee from a creditworthy entity, (ii) a standby irrevocable letter of credit (in a form and amount and for a term reasonably acceptable to Seller and issued by a financial institution reasonably
acceptable to Seller), (iii) a prepayment, or (iv) a cash payment security deposit (to be held by Seller without obligation for payment of interest thereon). 


ARTICLE VII 

QUALITY 
  

	7.1	Specifications. All Feedstock sold and delivered to Buyer at each applicable Receipt Point pursuant to this Agreement shall conform to the applicable specifications set forth in Schedule 7.1 (the
“Specifications”). 

  

	7.2	Off-Spec Feedstock. 

  

	 	(a)	The Parties will work together to minimize (i) any deliveries or receipts of Feedstock that does not or will not conform to the Specifications (“Off-Spec Feedstock”), and (ii) the negative
consequences that may result if and when Off-Spec Feedstock is delivered at a Receipt Point. 

  

	 	(b)	 Seller shall be liable for any damages incurred by Buyer to the extent arising out of or resulting from Off-Spec Feedstock delivered by Seller to
Buyer in accordance with the provisions of this Agreement (including delivery by Buyer to Downstream Buyer of Off-Spec Ethylene (as defined in the Ethylene Sales 



  
 12 










	 	
Agreement), the off-specification nature of which reasonably resulted from such Off-Spec Feedstock); provided, however, that Seller shall not be so liable if (i) Buyer fails to act as
a Reasonable and Prudent Operator in (A) accepting, testing, handling, storing, or throughputting the Off-Spec Feedstock or (B) failing to detect the off-specification nature thereof, or (ii) notwithstanding Buyer’s acting as a
Reasonable and Prudent Operator, Buyer accepts Off-Spec Feedstock with actual knowledge of the off-specification nature thereof. 

  

	 	(c)	Notwithstanding clauses (a) and (b) above, Seller’s liability in connection with the delivery by Seller to a Receipt Point of any Off-Spec Feedstock, on a per Gallon basis, shall not exceed
the amount in $/Gallon calculated as (i) 300% of the amount to be reimbursed to Seller in the applicable Month or Months pursuant to Article V divided by (ii) the total quantity (Gallons) of Feedstock delivered in the
applicable Month or Months. 

 ARTICLE VIII 

MEASUREMENT AND TESTING 
 Seller or its
designee shall own, operate and maintain, at or proximate to each Receipt Point, the metering equipment necessary to measure the quantity of each Feedstock delivered under this Agreement. All measurements and/or tests shall be made in accordance
with the latest standards or guidelines published by the ASTM or other applicable industry standard methods. Seller’s (or its designee’s) volume and/or other measurements of Feedstock shall be used for billing purposes, unless proved to be
in error. Buyer’s laboratory analysis and methods shall determine whether Feedstock specifications have been met, unless Seller proves to Buyer’s reasonable satisfaction that Buyer’s analysis report is erroneous. No Feedstock quantity
claims will be made, including pursuant to Article VII, unless the difference is more than one percent (1%) of the invoiced quantity. 

ARTICLE IX 
 FORCE
MAJEURE 
  

	9.1	Performance Excused. Buyer shall not be liable for any delay or failure in performance hereunder if and to the extent such delay or failure is a result of Force Majeure, except for the performance of any payment
obligation that has accrued prior to the Force Majeure event. Other than in the event of an extended period of Force Majeure pursuant to Section 9.5, nothing contained herein, express or implied, shall be construed to permit Seller to
withhold, delay, or condition payment of any portion of the Feedstock Shortfall Fee in the event that a Seller Deficiency Quantity accrues as a result of the occurrence or continuance of a Force Majeure; provided, however, that Buyer shall
not be entitled to that portion of the Feedstock Shortfall Fee that equals the portion of the then-current All Other Cash Production Costs that Buyer did not actually incur during the continuance of such Force Majeure. 


 

	9.2	 Force Majeure Defined. The term “Force Majeure” shall mean any cause, whether of the kind enumerated herein or otherwise,
which is not within the reasonable control of Buyer, and which by the exercise of reasonable diligence Buyer is unable to prevent or 



  
 13 










	 	
overcome, and which wholly or partially prevents or delays Buyer’s performance of any of its obligations under this Agreement (other than any payment obligations hereunder), including any of
the following which satisfy the foregoing criteria: acts of God; strikes, lockouts or other industrial disputes or disturbances; acts of the public enemy, sabotage, wars, blockades, insurrections, riots and other civil disturbances; epidemics;
landslides, floods, lightning, earthquakes, fires, tornadoes, hurricanes, named storms or other weather events that necessitate extraordinary measures and expenses to maintain operations of any of the Plants, and warnings for any of the foregoing
which may necessitate the precautionary shut-down of any Plant, any portion thereof, or other related facilities; arrests and restraints of governments (either federal, state, civil or military), including any orders of courts or of a Governmental
Authority; explosions, breakage or accidents to equipment, machinery, any Plant or any portion thereof, or lines of pipe, or the making of repairs or alterations to any of the foregoing necessitated as a result of a Force Majeure event; inability to
secure, or unavoidable delays in securing, labor or materials that are required for Buyer’s performance hereunder; electric power shortages or outages; or the necessity for compliance with any applicable Law. 


 

	9.3	Force Majeure Notice. As soon as reasonably possible after the occurrence of a Force Majeure event, Buyer shall provide written notice to Seller, and in such notice shall give reasonably full particulars
concerning the nature, scope and anticipated duration of the Force Majeure. 

  

	9.4	Settlement of Industrial Disturbances. Notwithstanding anything contained herein to the contrary, the settlement of strikes, lockouts or other industrial disturbances shall be entirely within the discretion of
the Party experiencing such situations, and nothing herein shall require such Party to settle industrial disputes by yielding to demands made on it when it considers such action inadvisable. 


 

	9.5	Extended Force Majeure. If, after 45 consecutive Days have elapsed since the commencement of a Force Majeure continuously affecting any Plant, and Buyer has been rendered and remains unable, wholly or in part, by
such Force Majeure to accept delivery of a quantity of Feedstock during a given Contract Year equal to the Annual Quantity, then (a) the Annual Quantity shall be reduced by a quantity of Feedstock equal to the annualized average of such
shortfall, (b) Seller shall be credited such portion of the Feedstock Shortfall Fee(s) paid during the Contract Year (if any) for such deficient quantities, and (c) if (but only if) both Parties are entitled to insurance proceeds from the
same insurance carrier, Buyer shall be entitled to any insurance proceeds from such carrier accruing during such extended period of Force Majeure on a first priority basis. Buyer shall notify Seller as soon as reasonably practicable if and when
Buyer determines such Force Majeure is no longer continuing. Upon receipt of such notice by Seller, the Parties’ respective obligations during such Contract Year to sell and tender, and purchase and receive, a quantity of Feedstock equal to the
Annual Quantity, less that quantity of Feedstock determined in accordance with clause (a) above, shall be reinstated for all purposes hereunder. 


  
 14 









 ARTICLE X 

TERMINATION 
  

	10.1	General. In addition to the further provisions of this Article X, this Agreement shall terminate upon the expiration of the Initial Term or any Renewal Term, as the case may be, and shall be
terminable (a) upon the written agreement of the Parties, (b) by any Party following an uncured breach of this Agreement by the other Party, for a period of 60 Days after receipt by the breaching Party of written notice thereof,
(c) by any Party pursuant to Force Majeure in accordance with Section 10.5, (d) upon the effective date of termination of the Ethylene Sales Agreement, (i) by Seller only, if such termination results from the uncured
breach by Buyer thereunder, and (ii) by Buyer only, if such termination does not result from the uncured breach by Buyer thereunder, or (e) by Buyer only, upon the effective date of expiration (if any) of the Ethylene Sales Agreement.


  

	10.2	Seller Suspension. Without prejudice to any other rights and remedies available under this Agreement, Seller may suspend delivery of Feedstock upon seven Days’ advance written notice in any of the following
circumstances: (a) Buyer has failed to make payments in full when due; (b) Buyer has failed to comply with its obligations under Section 6.5; or (c) at Seller’s reasonable discretion, instead of or prior to
terminating this Agreement, upon the occurrence of any Buyer Event of Default under Section 10.3(b) below. Upon and for the duration of such suspension, Seller shall be relieved of obligations to supply Feedstock under this Agreement,
but Buyer shall not be discharged of any of its obligations under this Agreement. Seller shall resume delivering Feedstock as soon as reasonably practicable following the cure of the events listed above and in any case within two Business Days of
such cure. 

  

	10.3	Events of Default. 

  

	 	(a)	Seller Event of Default. A “Seller Event of Default” shall be deemed to exist upon the occurrence and during the continuance of any one or more of the following events: (i) Seller breaches a
material term of this Agreement, and such breach is not cured within 60 Days following written notice from Buyer; or (ii) Seller fails to pay any amount due under this Agreement in full within 60 Days of the due date of such payment, subject to
Section 17.2. 

  

	 	(b)	Buyer Event of Default. A “Buyer Event of Default” shall be deemed to exist upon the occurrence and during the continuance of any one or more of the following events: (i) Buyer breaches a
material term of this Agreement, and such breach is not cured within 60 Days following written notice from Seller; or (ii) Buyer fails to pay any amount due under this Agreement in full within 60 Days of the due date of such payment, subject to
Section 17.2. 

  

	10.4	Remedies for Events of Default. 

  

	 	(a)	 Upon the occurrence of any Seller Event of Default or Buyer Event of Default that is not cured within the period of time provided by this Agreement,
if any, Buyer (in the case of a Seller Event of Default) or Seller (in the case of a Buyer 



  
 15 










	 	
Event of Default), as applicable, shall have the right to terminate this Agreement with 60 Days’ advance written notice to the defaulting Party and to pursue any other remedy provided under
this Agreement or now or hereafter existing at Law or in equity. Except in such circumstance or as elsewhere expressly provided in this Agreement, each Party waives any right to terminate this Agreement. If a fact giving rise to a right of
termination is wholly or partly overcome during such 60-Day notice period, then any notice of termination furnished under this Article X shall be deemed cancelled and of no effect and this Agreement shall remain in full force and effect.


  

	 	(b)	Other than as expressly provided in this Agreement, Seller will not be entitled to suspend or terminate the delivery of Feedstock to Buyer under this Agreement in any circumstance, including in connection with the
exercise of a right of offset or other equitable remedy, and any purported suspension or termination of any delivery of Feedstock to Buyer shall be deemed to be a material breach of this Agreement by Seller under this Article X and
permit Buyer to exercise the remedies contemplated in this Section 10.4. 

  

	10.5	Termination for Extended Force Majeure. If a Force Majeure continues, or its consequence remains, such that Buyer is unable to substantially comply with its obligations under this Agreement with respect to all
Plants continuously for a period in excess of 12 Months, then, provided such Force Majeure is still in effect at the time of notice, Seller may terminate this Agreement upon 30 Days’ advance notice without any liability upon either of the
Parties to the other Party except to the extent that any amount shall have accrued prior to the occurrence of the event of Force Majeure. 

  

	10.6	Effect of Termination. Except as expressly provided in Section 10.1, no Party shall have any right to terminate this Agreement. Upon the termination of this Agreement, this Agreement shall become void
and have no effect, subject to Section 17.3, except that such termination shall not affect any rights or obligations that have vested, matured or accrued at any time prior to such termination. 


ARTICLE XI 

REPRESENTATIONS AND WARRANTIES 
  

	11.1	Title to Feedstock. Seller warrants title to all Feedstock supplied hereunder and covenants that Seller has all necessary right, authority and interest to sell and deliver the Feedstock under this Agreement and
that such Feedstock will be free from liens, encumbrances, adverse claims and proprietary rights at the passing of title at each Receipt Point. 

  

	11.2	Warranty to Specification. Seller warrants to Buyer that Feedstock delivered hereunder meets the applicable Specifications. 

  

	11.3	Financial Obligations. Buyer warrants to Seller that it is unaware, as of the date hereof, of any fact related to its financial condition that would prevent it from performing its financial obligations under this
Agreement in accordance with the terms and conditions contained herein. 


  
 16 










	11.4	Disclaimer of any Other Warranties. EXCEPT AS OTHERWISE EXPRESSLY SET FORTH HEREIN, THE PARTIES MAKE NO, AND EXPRESSLY DISCLAIM ANY, REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED, AT LAW OR IN EQUITY,
INCLUDING WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, REGARDING ANY PLANT OR PORTION THEREOF, THE FEEDSTOCK OR WITH RESPECT TO THE SUBJECT MATTER HEREOF. 


ARTICLE XII 
 LIMITATIONS
ON LIABILITIES 
  

	12.1	Consequential Loss or Damage. Notwithstanding any other provision of this Agreement, no Party shall be liable to the other Party for or in respect of any consequential loss or damage, special or punitive damages
or loss of profits or business interruption, suffered or incurred by any other Party arising out of, in connection with, or resulting from, this Agreement, whether any claim for such loss or damage is based on tort (including negligence), strict
liability, contract (including breach of or failure to perform this Agreement or the breach of any representation or warranty hereunder, whether express or implied) or otherwise, except as provided in Section 12.2. 


 

	12.2	Liquidated Damages Not Penalty. Because of the unique nature of the economic damages and losses that would be sustained under this Agreement where specified damages are used, it is difficult or impossible to
determine with precision the amount of damages that would or might be incurred by a non-breaching Party in such circumstances. Therefore, it is acknowledged and agreed by the Parties that in such circumstances: (a) it would be impracticable or
extremely difficult to fix the actual damages to a non-breaching Party resulting therefrom; (b) any sums that would be payable under this Agreement in such circumstances are stipulated by the Parties to be in the nature of liquidated damages
and not a penalty, and are acknowledged and agreed to be fair, reasonable and appropriate; (c) such payment represents a reasonable estimate of compensation for a portion of the losses that may reasonably be anticipated from such failure and
shall, without duplication, be the sole and exclusive measurement of monetary damages of such non-breaching Party with respect to such circumstances; and (d) if the breaching Party challenges the enforceability of such liquidated damages, the
non-breaching Party may elect at its option for damages in such circumstances to be based on actual damages instead of liquidated damages and such actual damages shall not be subject to the limitations set forth in Section 12.1.


  

	12.3	Exclusive Remedies. Notwithstanding anything to the contrary contained in this Agreement, from and after the Effective Date, this Agreement contains the Parties’ exclusive remedies against each other with
respect to the transactions contemplated hereby, including breaches of the representations, warranties, and agreements of the Parties contained in this Agreement or in any document delivered pursuant to this Agreement. 


  
 17 









 ARTICLE XIII 

INSURANCE 
 During the Term, each Party
shall, for all risks and circumstances that should and may be covered by insurance in accordance with prudent industry practices, purchase and maintain sufficient casualty, environmental, and property insurance in order to satisfy the legal
liabilities for bodily injuries and damages to properties (including the properties of such Party) as a result of or in association with the performance of this Agreement and sufficient third party liability insurance and other insurance(s) required
by applicable Law and any Governmental Authority. 
 ARTICLE XIV 

CONFIDENTIALITY 
  

	14.1	Information. Each of the Parties agrees that it will utilize any Confidential Information received from the other Party solely in connection with the performance of its obligations hereunder and the exercise by
the recipient Party of its rights and remedies hereunder and under applicable Law, and all such Confidential Information will be subject to and bound by the provisions set forth in this Article XIV. Upon termination of this Agreement,
the recipient Party shall return or destroy all such Confidential Information (and cease all further use and disclosure of such Confidential Information) that has been provided to it, together with all reproductions thereof in the recipient
Party’s possession; provided that the recipient Party shall have the right to retain copies of any such information and records that (a) were created by automatic computer generated backup systems or (b) relate to its
performance of any services and the exercise of its rights and remedies hereunder or under the Related Agreements and under applicable Law, and all such copies and the information reflected thereon shall be subject to the first sentence of this
Section 14.1 and to Section 14.2. 

  

	14.2	Definition. “Confidential Information” means any and all information (regardless of format or medium of exchange) that is disclosed by any disclosing Party or any Affiliate, employee or agent
thereof to the recipient Party or any Affiliate, employee or agent of the recipient Party in connection with the performance of this Agreement or the Related Agreements provided that Confidential Information shall not include any information that is
publicly known or independently developed by such recipient Party. It is further understood that each Party may have the opportunity as a result of proximity or close operational ties to observe or obtain Confidential Information of any other Party
and agrees not to divulge or use such information other than as set forth in this Article XIV. 

  

	14.3	 Legal Requirement. If the recipient Party is legally required (by interrogatories, discovery requests for information or documents, subpoena,
civil or criminal investigative demand or similar process) to disclose any Confidential Information, it is agreed that the recipient Party prior to disclosure will use commercially reasonable efforts to provide the disclosing Party with prompt
notice of such request(s) so that the disclosing Party may seek an appropriate protective order or other appropriate remedy or waive the recipient Party’s compliance with this Article XIV. If such protective order or other remedy is
not obtained, or the disclosing Party grants a waiver hereunder, the recipient Party required to furnish Confidential Information may furnish that portion (and 



  
 18 










	 	
only that portion) of the Confidential Information which, in the opinion of such Party’s counsel, the recipient Party is legally compelled to disclose, and the recipient Party will exercise
commercially reasonable efforts to obtain reliable assurance that confidential treatment will be accorded any Confidential Information so furnished. Disclosure of Confidential Information by the recipient Party shall not violate this
Article XIV to the extent that the recipient Party (or its ultimate parent) in the exercise of reasonable good faith judgment deems it necessary, pursuant to law, regulation or stock exchange rule, to disclose such information in or in
connection with filings made with the U.S. Securities and Exchange Commission, any securities exchange upon which debt or equity securities of such recipient Party or its parent may be listed, to any Governmental Authority or in presentations to
lenders or ratings agencies. 

  

	14.4	Survival. The provisions of this Article XIV shall survive the termination of this Agreement for a period of three years following such termination. 


ARTICLE XV 
 ASSIGNMENT;
CHANGE OF CONTROL 
  

	15.1	Assignment Generally. Each Party hereunder shall be entitled to assign all of its rights and obligations under this Agreement with the prior written consent of the other Party, in each case which consent shall
not be unreasonably withheld by the non-assigning Party. No assignment hereunder shall release the assigning Party from any of its obligations under this Agreement except to the extent expressly agreed in writing by each other Party. Any purported
assignment of this Agreement in violation of this Section 15.1 is null and void ab initio. 

  

	15.2	Assignment to Affiliates. Notwithstanding the foregoing, this Agreement may be assigned by a Party to an Affiliate (other than the other Party) without the consent of the other Party, provided that such
Affiliate executes an agreement satisfactory to the other Party, whereby the Affiliate assumes all of the applicable obligations of the assigning Party under this Agreement; provided further that the assigning Party shall not be released of
its obligations under this Agreement such that the assigning Party and its Affiliate shall be jointly and severally liable for the performance of the obligations of the assigning Party hereunder. 


ARTICLE XVI 
 TAXES

 During the Term, Seller shall be responsible for the payment of any sales, use, and excise taxes or any other tax, fee or charge due and levied by
any federal, state, local or other Governmental Authority on the Feedstock prior to each Receipt Point and for any taxes, fees or charges due as a result of Seller making Feedstock available to Buyer hereunder, except to the extent any such taxes
are, by applicable Law, required to be paid directly by Buyer, in which event such taxes shall be paid by Buyer and reimbursed by Seller, and Seller shall indemnify, defend and hold Buyer harmless from any liability against such taxes, fees or
charges. During the Term, Buyer shall be responsible for the payment of any taxes, fees or charges applicable to the Feedstock at or downstream of each Receipt Point and for taxes, fees and charges applicable to any products


  
 19 









 
produced or manufactured from the use of such Feedstock, except to the extent any such taxes are, by applicable Law, required to be paid directly by Seller, in which event such taxes shall be
paid by Seller and reimbursed by Buyer, and Buyer shall indemnify, defend and hold Seller harmless from any liability against such taxes, fees or charges. The above notwithstanding, Seller shall remain liable for and Buyer shall have no obligation
to reimburse Seller for (a) any taxes imposed on or calculated based upon net profits, gross or net income, profit margin or gross receipts of Seller, (b) any taxes measured by capital value or net worth of Seller; or (c) any ad
valorem or personal property taxes on any Plant or the property of Seller. Any penalties or interest imposed by a taxing authority on either Party due to failure to pass information by the other Party will be paid by the Party failing to pass along
necessary tax notices. 
 ARTICLE XVII 

MISCELLANEOUS 
  

	17.1	Choice of Law; Submission to Jurisdiction. This Agreement shall be subject to and governed by the laws of the State of Texas, excluding any conflicts-of-law rule or principle that might refer the construction or
interpretation of this Agreement to the laws of another state. Each of the Parties hereby agrees: (a) to submit to the exclusive jurisdiction of any state or federal court sitting in Houston, Texas for the enforcement of any arbitration
decision pursuant to Section 17.2, (b) that all claims in respect of any such action or proceeding may be heard and determined in any such court, (c) that such Party will not bring any action or proceeding arising out of or
relating to this Agreement in any other court, and (d) that such Party waives any defense of inconvenient forum to the maintenance of any such action or proceeding, and waives any bond, surety or other security that might be required of any
other Party with respect to any such action or proceeding. 

  

	17.2	Dispute Resolution. 

  

	 	(a)	The dispute resolution provisions set forth in this Section 17.2 shall be the final, binding and exclusive means to resolve all disputes, controversies or claims (each, a “dispute”) arising
under the Agreement, and EACH PARTY IRREVOCABLY WAIVES ANY RIGHT TO ANY TRIAL BY JURY WITH RESPECT TO ANY DISPUTE ARISING UNDER THIS AGREEMENT. 

  

	 	(b)	If a dispute arises, the following procedures shall be implemented: 

  

	 	(i)	Any Party may at any time invoke the dispute resolution procedures set forth in this Section 17.2 as to any dispute by providing written notice of such action to the other Parties. 


 

	 	(ii)	Notwithstanding the existence of any dispute or the pendency of any procedures pursuant to this Section 17.2, the Parties agree and undertake that all payments not in dispute shall continue to be made and
that all obligations not in dispute shall continue to be performed. 

  

	 	(iii)	 Within 30 days after receipt of notice of a dispute under Section 17.2(b)(i), representatives of the Parties shall engage in non-binding
mediation, and a 



  
 20 










	 	
specific timetable and completion date for its implementation shall also be agreed upon. If the completion date therefor shall occur without the Parties having resolved the dispute, then the
Parties shall proceed under Section 17.2(b)(iv). 

  

	 	(iv)	If, after satisfying the requirement above, the dispute is not resolved, the Parties shall resolve the dispute by a binding arbitration, to be held in the State of Texas pursuant to the Federal Arbitration Act and in
accordance with the then-prevailing Commercial Arbitration Rules of the American Arbitration Association (the “AAA”). The AAA shall select one arbitrator. Each Party shall bear its own expenses incurred in connection with
arbitration and the fees and expenses of the arbitrator shall be shared equally by the Parties involved in the dispute and advanced by them from time to time as required. It is the mutual intention and desire of the Parties that the arbitrator be
selected as expeditiously as possible following the submission of the dispute to arbitration. Once the arbitrator is selected and except as may otherwise be agreed in writing by the Parties involved in such dispute or as ordered by the arbitrator
upon substantial justification shown, the hearing for the dispute will be held within 60 days of submission of the dispute to arbitration. The arbitrator shall render his final award within 60 days, subject to extension by the arbitrator upon
substantial justification shown of extraordinary circumstances, following conclusion of the hearing and any required post hearing briefing or other proceedings ordered by the arbitrator. Any discovery in connection with arbitration hereunder shall
be limited to information directly relevant to the controversy or claim in arbitration. The decision of the arbitrator in any such proceeding will be reasoned, final and binding and final judgment may be entered upon such an award in any court of
competent jurisdiction, but entry of such judgment will not be required to make such award effective. Any action against any Party ancillary to arbitration (as determined by the arbitrator), including any action for provisional or conservatory
measures or action to enforce an arbitration award or any judgment entered by any court in respect of any thereof may be brought in any federal or state court of competent jurisdiction located within the State of Texas, and the Parties hereby
irrevocably submit to the non-exclusive jurisdiction of any federal or state court located within the State of Texas over any such action. The Parties hereby irrevocably waive, to the fullest extent permitted by Law, any objection which they may now
or hereafter have to the laying of venue of any such action brought in such court or any defense of inconvenient forum for the maintenance of such action. Each of the Parties agrees that a judgment in any such action may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law. 

  

	 	(c)	 The Parties agree that to the extent that there are two or more related disputes arising under (i) this Agreement, (ii) any guarantee issued
pursuant to Section 6.5 or (iii) any letter of credit issued pursuant to Section 6.5 (as between these Parties 



  
 21 










	 	
or the parties to such guarantee or letter of credit), then they consent to the consolidation of those disputes in circumstances where: 


 

	 	(i)	no arbitration is currently pending under (A) this Agreement, (B) any guarantee issued pursuant to Section 6.5 or (C) any letter of credit issued pursuant to Section 6.5; or


  

	 	(ii)	the tribunal in the first commenced arbitration (or the AAA where no tribunal has yet been constituted in either case) finds (having invited and allowed opportunity for submissions from all the parties to both
arbitrations) that it would be convenient and efficient to do so, having regard to the time and cost impact of consolidating the disputes into one proceeding. Such an application for consolidation must be brought prior to the constitution of a
tribunal in the second commenced arbitration in time, and should be resolved within one Month of the application being received by the relevant tribunal/the AAA. 

  


	17.3	Survival. Cancellation, expiration or termination of this Agreement shall not relieve the Parties of any obligations that, by their very nature, must survive said cancellation, expiration or termination,
including choice of law (Section 17.1), dispute resolution provisions (Section 17.2), limitations of liability (Article XII), confidentiality provisions (Article XIV), and defined terms and certain
miscellaneous provisions (Article I and Article XVII), all of which shall remain in effect until all rights, obligations and remedies have been finally extinguished, and all disputes under Section 17.2 have been
finally resolved. Notwithstanding the foregoing, the statute of limitations for bringing any action with respect to this Agreement or any Party’s performance hereunder is not extended by the provisions of this Section 17.3.


  

	17.4	Notice. All notices, requests or consents provided for by, or permitted to be given pursuant to, this Agreement must be in writing and must be given by depositing same in the United States mail, addressed to the
Person to be notified, postpaid, and registered or certified with return receipt requested or by delivering such notice in person or by facsimile or e-mail to such Party. Notice given by personal delivery or mail shall be effective upon actual
receipt. Notice given by facsimile or e-mail shall be effective upon actual receipt if received during the recipient’s normal business hours or at the beginning of the recipient’s next Business Day after receipt if not received during the
recipient’s normal business hours. All notices to be sent to a Party pursuant to this Agreement shall be sent to or made at the address set forth below such Party’s signature to this Agreement or at such other address as such Party may
stipulate to the other Parties in the manner provided in this Section 17.4.

	17.5	Entire Agreement. This Agreement and the Related Agreements (including any exhibits or schedules hereto or thereto) constitute the entire agreement of the Parties relating to the matters contained herein and
therein, superseding all prior contracts or agreements, whether oral or written, relating to the matters contained herein and therein. 

  

	17.6	Amendment or Modification. This Agreement may be amended or modified from time to time only by the written agreement of all the Parties hereto and each such written agreement shall be designated on its face an
“Amendment” or an “Addendum” to this Agreement. 

  

	17.7	Counterparts. This Agreement may be executed in any number of counterparts with the same effect as if all signatory parties had signed the same document. All counterparts shall be construed together and shall
constitute one and the same instrument. 

  

	17.8	Severability. If any provision of this Agreement shall be finally determined to be unenforceable, illegal or unlawful, such provision shall, so long as the economic and legal substance of the transactions
contemplated hereby is not affected in any materially adverse manner as to any Party, be deemed severed from this Agreement and the remainder of this Agreement shall remain in full force and effect. 


 

	17.9	Further Assurances. In connection with this Agreement and all transactions contemplated by this Agreement, each signatory party hereto agrees to execute and deliver such additional documents and instruments and
to perform such additional acts as may be necessary or appropriate to effectuate, carry out and perform all of the terms, provisions and conditions of this Agreement and all such transactions. 


 

	17.10	No Waiver. Failure of any Party to require performance of any provision of this Agreement shall not affect such Party’s right to full performance thereof at any time thereafter, and the waiver by any Party
of a breach of any provision hereof shall not constitute a waiver of any similar breach in the future or of any other breach or nullify the effectiveness of such provision. 


 

	17.11	Set Off. Each Party has the right to set off against any amounts due to the other Party hereunder any and all amounts that the other Party owes to the first Party under this Agreement or the Related Agreements.


  

	17.12	Rights of Third Parties. The provisions of this Agreement are enforceable solely by the Parties to this Agreement, and no third party shall have the right, separate and apart from the Parties to this Agreement,
to enforce any provision of this Agreement or to compel any Party to this Agreement to comply with the terms of this Agreement. 

  

	17.13	Legal Relationship. The Parties do not intend to create any sort of partnership, joint venture or any other legal entity by entering into or performing this Agreement. Each Party will perform its obligations
under this Agreement in its own name. Each Party will be solely responsible for its own acts and omissions (and the acts and omissions of its employees, consultants and other agents), and without the express written consent of each other Party, no
Party will have the authority nor will purport to act for, or legally bind, any other Party in any transaction.
