 General Terms and Conditions 

Base Contract for Sale and Purchase of Natural Gas 

SECTION 1. PURPOSE AND PROCEDURES 
 1.1. These General
Terms and Conditions are intended to facilitate purchase and sale transactions of Gas on a Firm or Interruptible basis. “Buyer” refers to the party receiving Gas and “Seller” refers to the party delivering Gas. The entire
agreement between the parties shall be the Contract as defined in Section 2.9. 
  

	
	The parties have selected either the “Oral Transaction Procedure” or the “Written Transaction Procedure” as indicated on the Base Contract.
	  
 Oral Transaction Procedure:

	
	 1.2. The parties will use the following Transaction Confirmation procedure. Any Gas purchase and sale transaction may be effectuated in an
EDI transmission or telephone conversation with the offer and acceptance constituting the agreement of the parties. The parties shall be legally bound from the time they so agree to transaction terms and may each rely thereon. Any such transaction
shall be considered a “writing” and to have been “signed”. Notwithstanding the foregoing sentence, the parties agree that Confirming Party shall, and the other party may, confirm a telephonic transaction by sending the other
party a Transaction Confirmation by facsimile, EDI or mutually agreeable electronic means within three Business Days of a transaction covered by this Section 1.2 (Oral Transaction Procedure) provided that the failure to send a Transaction
Confirmation shall not invalidate the oral agreement of the parties. Confirming Party adopts its confirming letterhead, or the like, as its signature on any Transaction Confirmation as the identification and authentication of Confirming Party. If
the Transaction Confirmation contains any provisions other than those relating to the commercial terms of the transaction (i.e., price, quantity, performance obligation, delivery point, period of delivery and/or transportation conditions), which
modify or supplement the Base Contract or General Terms and Conditions of this Contract (e.g., arbitration or additional representations and warranties), such provisions shall not be deemed to be accepted pursuant to Section 1.3 but must be
expressly agreed to by both parties; provided that the foregoing shall not invalidate any transaction agreed to by the parties.
  

	Written Transaction Procedure:
	
	1.2. The parties will use the following Transaction Confirmation procedure. Should the parties come to an agreement regarding a Gas purchase and sale transaction for a particular Delivery Period, the Confirming Party shall, and the
other party may, record that agreement on a Transaction Confirmation and communicate such Transaction Confirmation by facsimile, EDI or mutually agreeable electronic means, to the other party by the close of the Business Day following the date of
agreement. The parties acknowledge that their agreement will not be binding until the exchange of nonconflicting Transaction Confirmations or the passage of the Confirm Deadline without objection from the receiving party, as provided in
Section 1.3.

 1.3. If a sending party’s Transaction Confirmation is materially different from the receiving party’s understanding
of the agreement referred to in Section 1.2, such receiving party shall notify the sending party via facsimile, EDI or mutually agreeable electronic means by the Confirm Deadline, unless such receiving party has previously sent a Transaction
Confirmation to the sending party. The failure of the receiving party to so notify the sending party in writing by the Confirm Deadline constitutes the receiving party’s agreement to the terms of the transaction described in the sending
party’s Transaction Confirmation. If there are any material differences between timely sent Transaction Confirmations governing the same transaction, then neither Transaction Confirmation shall be binding until or unless such differences are
resolved including the use of any evidence that clearly resolves the differences in the Transaction Confirmations. In the event of a conflict among the terms of (i) a binding Transaction Confirmation pursuant to Section 1.2, (ii) the oral
agreement of the parties which may be evidenced by a recorded conversation, where the parties have selected the Oral Transaction Procedure of the Base Contract, (iii) the Base Contract, and (iv) these General Terms and Conditions, the
terms of the documents shall govern in the priority listed in this sentence.

 1.4. The parties agree that each party may electronically record all telephone conversations with respect to
this Contract between their respective employees, without any special or further notice to the other party. Each party shall obtain any necessary consent of its agents and employees to such recording. Where the parties have selected the Oral
Transaction Procedure in Section 1.2 of the Base Contract, the parties agree not to contest the validity or enforceability of telephonic recordings entered into in accordance with the requirements of this Base Contract.

acceptable in industry practice to support the amount charged. If the actual quantity delivered is not known by the billing date, billing will be prepared based on the quantity of Scheduled Gas. The invoiced quantity will then be adjusted to the
actual quantity on the following Month’s billing or as soon thereafter as actual delivery information is available. 
 7.2. Buyer shall remit the amount
due under Section 7.1 in the manner specified in the Base Contract, in immediately available funds, on or before the later of the Payment Date or 10 Days after receipt of the invoice by Buyer; provided that if the Payment Date is not a Business

 7.4. If the invoiced party, in good faith, disputes the amount of any such invoice or any part thereof, such
invoiced party will pay such amount as it concedes to be correct; provided, however, if the invoiced party disputes the amount due, it must provide supporting documentation acceptable in industry practice to support the amount paid or disputed
without undue delay. In the event the parties are unable to resolve such dispute, either party may pursue any remedy available at law or inequity to enforce its rights pursuant to this Section. 

7.5. If the invoiced party fails to remit the full amount payable when due, interest on the unpaid portion shall accrue from the date due until the date of

audit, and to obtain copies shall not be available with respect to proprietary information not directly relevant to transactions under this Contract. All invoices and billings shall be conclusively presumed final and accurate and all associated
claims for under- or overpayments shall be deemed waived unless such invoices or billings are objected to in writing, with adequate explanation and/or documentation, within two years after the Month of Gas delivery. All retroactive adjustments under
Section 7 shall be paid in full by the party owing payment within 30 Days of Notice and substantiation of such inaccuracy. 
 7.7. Unless the parties
have elected on the Base Contract not to make this Section 7.7 applicable to this Contract, the parties shall net all undisputed amounts due and owing, and/or past due, arising under the Contract such that the party owing the greater amount

“Non-Defaulting Party”) shall have the right, at its sole election, to immediately withhold and/or suspend deliveries or payments upon Notice and/or to terminate and liquidate the transactions under
the Contract, in the manner provided in Section 10.3, in addition to any and all other remedies available hereunder. 

  
 Page 10 of 25 

 10.3. If an Event of Default has occurred and is continuing, the
Non-Defaulting Party shall have the right, by Notice to the Defaulting Party, to designate a Day, no earlier than the Day such Notice is given and no later than 20 Days after such Notice is given, as an early
termination date (the “Early Termination Date”) for the liquidation and termination pursuant to Section 10.3.1 of all transactions under the Contract, each a “Terminated Transaction”. On the Early Termination Date, all
transactions will terminate, other than those transactions, if any, that may not be liquidated and terminated under applicable law (“Excluded Transactions”), which Excluded Transactions must be liquidated and terminated as soon thereafter
as is legally permissible, and upon termination shall be a Terminated Transaction and be valued consistent with Section 10.3.1 below. With respect to each Excluded Transaction, its actual termination date shall be the Early Termination Date for
purposes of Section 10.3.1. 
  

	
	 The parties have selected either “Early Termination Damages Apply” or “Early Termination Damages Do No Apply” as
indicated on the Base Contract.
  

	Early Termination Damages Apply:
	  
 10.3.1. As of the Early Termination Date, the Non-Defaulting Party shall determine, in good faith and in a commercially reasonable manner, (i) the amount owed (whether or not then due) by each party with respect to all Gas delivered and received between
the parties under Terminated Transactions and Excluded Transactions on and before the Early Termination Date and all other applicable charges relating to such deliveries and receipts (including without limitation any amounts owed under
Section 3.2), for which payment has not yet been made by the party that owes such payment under this Contract and (ii) the Market Value, as defined below, of each Terminated Transaction. The
Non-Defaulting Party shall (x) liquidate and accelerate each Terminated Transaction at its Market Value, so that each amount equal to the difference between such Market Value and the Contract Value, as
defined below, of such Terminated Transaction(s) shall be due to the Buyer under the Terminated Transaction(s) if such Market Value exceeds the Contract Value and to the Seller if the opposite is the case; and (y) where appropriate, discount
each amount then due under clause (x) above to present value in a commercially reasonable manner as of the Early Termination Date (to take account of the period between the date of liquidation and the date on which such amount would have
otherwise been due pursuant to the relevant Terminated Transactions).
  
 For purposes
of this Section 10.3.1, “Contract Value” means the amount of Gas remaining to be delivered or purchased under a transaction multiplied by the Contract Price, and “Market Value” means the amount of Gas remaining to be
delivered or purchased under a transaction multiplied by the market price for a similar transaction at the Delivery Point determined by the Non-Defaulting Party in a commercially reasonable manner. To
ascertain the Market Value, the Non-Defaulting Party may consider, among other valuations, any or all of the settlement prices of NYMEX Gas futures contracts, quotations from leading dealers in energy swap
contracts or physical gas trading markets, similar sales or purchases and any other bona fide third-party offers, all adjusted for the length of the term and differences in transportation costs. A party shall not be required to enter into a
replacement transaction(s) in order to determine the Market Value. Any extension(s) of the term of a transaction to which parties are not bound as of the Early Termination Date (including but not limited to “evergreen provisions”) shall
not be considered in determining Contract Values and Market Values. For the avoidance of doubt, any option pursuant to which one party has the right to extend the term of a transaction shall be considered in determining Contract Values and Market
Values. The rate of interest used in calculating net present value shall be determined by the Non-Defaulting Party in a commercially reasonable manner.

 

	Early Termination Damages Do Not Apply:
	  
 10.3.1 As of the Early Termination Date, the Non-Defaulting Party shall determine, in good faith and in a commercially reasonable manner, the amount owed (whether or not then due) by each party with respect to all Gas delivered and received between the parties
under Terminated Transactions and Excluded Transactions on and before the Early Termination Date and all other applicable charges relating to such deliveries and receipts (including without limitation any amounts owed under Section 3.2), for
which payment has not yet been made by the party that owes such payment under this Contract.

	Bilateral Setoff Option:
	
	 10.3.2. The Non-Defaulting Party shall net or aggregate, as appropriate, any and all amounts owing
between the parties under Section 10.3.1, so that all such amounts are netted or aggregated to a single liquidated amount payable by one party to the other (the “Net Settlement Amount”). At its sole option and without prior Notice to
the Defaulting Party, the Non-Defaulting Party is hereby authorized to setoff any Net Settlement Amount against (i) any margin or other collateral held by a party in connection with any Credit Support
Obligation relating to the Contract; and (ii) any amount(s) (including any excess cash margin or excess cash collateral) owed or held by the party that is entitled to the Net Settlement Amount under any other agreement or arrangement between
the parties.
  

	Triangular Setoff Option:
	  
 10.3.2 The Non-Defaulting
Party shall net or aggregate, as appropriate, any and all amounts owing between the parties under Section 10.3.1, so that all such amounts are netted or aggregated to a single liquidated amount payable by one party to the other (the “Net
Settlement Amount”). At its sole option, and without prior Notice to the Defaulting Party, the Non-Defaulting Party is hereby authorized to setoff (i) any Net Settlement Amount against any margin or
other collateral held by a party in connection with any Credit Support Obligation relating to the Contract; (ii) any Net Settlement Amount against any amount(s) (including any excess cash margin or excess cash collateral) owed by or to a party
under any other agreement or arrangement between the parties; (iii) any Net Settlement Amount owed to the Non-Defaulting Party against any amount(s) (including any excess cash margin or excess cash
collateral) owed by the Non-Defaulting Party or its Affiliates to the Defaulting Party under any other agreement or arrangement; (iv) any Net Settlement Amount owed to the Defaulting Party against any
amount(s) (including any excess cash margin or excess cash collateral) owed by the Defaulting Party to the Non-Defaulting Party or its Affiliates under any other agreement or arrangement; and/or (v) any
Net Settlement Amount owed to the Defaulting Party against any amount(s) (including any excess cash margin or excess cash collateral) owed by the Defaulting Party or its Affiliates to the Non-Defaulting Party
under any other agreement or arrangement.
  

	Other Agreement Setoffs Do Not Apply:
	  
 10.3.2 The Non-Defaulting
Party shall net or aggregate, as appropriate, any and all amounts owing between the parties under Section 10.3.1, so that all such amounts are netted or aggregated to a single liquidated amount payable by one party to the other {the “Net
Settlement Amount”). At its sole option and without prior Notice to the Defaulting Party, the Non-Defaulting Party may setoff any Net Settlement Amount against any margin or other collateral held by a
party in connection with any Credit Support Obligation relating to the Contract.
  

 10.3.3. If any obligation that is to be included in any netting, aggregation or setoff pursuant to Section 10.3.2 is
unascertained, the Non-Defaulting Party may in good faith estimate that obligation and net, aggregate or setoff, as applicable, in respect of the estimate, subject to the
Non-Defaulting Party accounting to the Defaulting Party when the obligation is ascertained. Any amount not then due which is included in any netting, aggregation or setoff pursuant to Section 10.3.2 shall
be discounted to net present value in a commercially reasonable manner determined by the Non-Defaulting Party. 

10.4. As soon as practicable after a liquidation, Notice shall be given by the Non-Defaulting Party to the Defaulting
Party of the Net Settlement Amount, and whether the Net Settlement Amount is due to or due from the Non-Defaulting Party. The Notice shall include a written statement explaining in reasonable detail the
calculation of the Net Settlement Amount, provided that failure to give such Notice shall not affect the validity or enforceability of the liquidation or give rise to any claim by the Defaulting Party against the
Non-Defaulting Party. The Net Settlement Amount as well as any setoffs applied against such amount pursuant to Section 10.3.2, shall be paid by the close of business on the second Business Day following
such Notice, which date shall not be earlier than the Early Termination Date. Interest on any unpaid portion of the Net Settlement Amount as adjusted by setoffs, shall accrue from the date due until the date of payment at a rate equal to the lower
of (i) the then-effective prime rate of interest published under “Money Rates” by The Wall Street Journal, plus two percent per annum; or (ii) the maximum applicable lawful interest rate.

from the Contract. 
 10.7. With respect to this Section 10, if the parties have executed a separate netting agreement with close-out netting provisions, the terms and conditions therein shall prevail to the extent inconsistent herewith. 

SECTION 11. FORCE MAJEURE 
 11.1. Except with regard to a
party’s obligation to make payment(s) due under Section 7, Section 10.4, and Imbalance Charges under Section 4, neither party shall be liable to the other for failure to perform a Firm obligation, to the extent such failure was
caused by Force Majeure. The term “Force Majeure” as employed herein means any cause not reasonably within the control of the party claiming suspension, as further defined in Section 11.2. 

11.2. Force Majeure shall include, but not be limited to, the following: (i) physical events such as acts of God, landslides, lightning, earthquakes,
fires, storms or storm warnings, such as hurricanes, which result in evacuation of the affected area, floods, washouts, explosions, breakage or accident or necessity of repairs to machinery or equipment or lines of pipe; (ii) weather related
events affecting an entire geographic region, such as low temperatures which cause freezing or failure of wells or lines of pipe; (iii) interruption and/or curtailment of Firm transportation and/or storage by Transporters; (iv) acts of
others such as strikes, lockouts or other industrial disturbances, riots, sabotage, insurrections or wars, or acts of terror; and (v) governmental actions such as necessity for compliance with any court order, law, statute, ordinance,
regulation, or policy having the effect of law promulgated by a governmental authority having jurisdiction. Seller and Buyer shall make reasonable efforts to avoid the adverse impacts of a Force Majeure and to resolve the event or occurrence once It
has occurred in order to resume performance. 
 11.3. Neither party shall be entitled to the benefit of the provisions of Force Majeure to the extent
performance is affected by any or all of the following circumstances: (i) the curtailment of interruptible or secondary Firm transportation unless primary, in-path, Firm transportation is also curtailed;
(ii) the party claiming excuse failed to remedy the condition and to resume the performance of such covenants or obligations with reasonable dispatch; or (ii) economic hardship, to Include, without limitation, Sellers ability to sell Gas
at a higher or more advantageous price than the Contract Price, Buyers ability to purchase Gas at a lower or more advantageous price than the Contract Price, or a regulatory agency disallowing, in whole or in part, the pass through of costs
resulting from this Contract; (iv) the loss of Buyer’s market(s) or Buyer’s inability to use or resell Gas purchased hereunder, except, in either case, as provided in Section 11.2; or (v) the loss or failure of Sellers gas

within the sole discretion of the party experiencing such disturbance. 
 11.5. The party whose performance is prevented by Force Majeure must provide Notice
to the other party. Initial Notice may be given orally; however, written Notice with reasonably full particulars of the event or occurrence is required as soon as reasonably possible. Upon providing written Notice of Force Majeure to the other
party, the affected party will be relieved of its obligation, from the onset of the Force Majeure event, to make or accept delivery of Gas, as applicable, to the extent and for the duration of Force Majeure, and neither party shall be deemed to have
failed in such obligations to the other during such occurrence or event.

 SECTION 14. MARKET DISRUPTION 

If a Market Disruption Event has occurred then the parties shall negotiate in good faith to agree on a replacement price for the Floating Price (or on a method
for determining a replacement price for the Floating Price) for the affected Day, and if the parties have not so agreed on or before the second Business Day following the affected Day then the replacement price for the Floating Price shall be
determined within the next two following Business Days with each party obtaining, in good faith and from non-affiliated market participants in the relevant market, two quotes for prices of Gas for the affected
Day of a similar quality and quantity in the geographical location closest in proximity to the Delivery Point and averaging the four quotes. If either party fails to provide two quotes then the average of the other party’s two quotes shall
determine the replacement price for the Floating Price. “Floating Price” means the price or a factor of the price agreed to in the transaction as being based upon a specified index. “Market Disruption Event’’ means, with
respect to an index specified for a transaction, any of the following events: (a) the failure of the index to announce or publish information necessary for determining the Floating Price; (b} the failure of trading to commence or the permanent
discontinuation or material suspension of trading on the exchange or market acting as the index; (c) the temporary or permanent discontinuance or unavailability of the index; (d) the temporary or permanent closing of any exchange acting as
the index; or (e) both parties agree that a material change in the formula for or the method of determining the Floating Price has occurred. For the purposes of the calculation of a replacement price for the Floating Price, all numbers shall be
rounded to three decimal places. If the fourth decimal number is five or greater, then the third decimal number shall be increased by one and if the fourth decimal number is less than five, then the third decimal number shall remain unchanged.

 SPECIAL PROVISIONS TO 

BASE CONTRACT FOR SALE AND PURCHASE OF NATURAL GAS 

Dated August 24, 2018 

by and between 
 GSF
Energy, L.L.C. (“Seller”) and 
 Trillium Transportation Fuels, LLC (“Buyer”) 

These Special Provisions amend the North American Energy Standards Board, Inc. (“NAESB”) Base Contract for Sale and purchase of Natural Gas and its
accompanying General Terms and Conditions, as published September 5, 2006 (the “Base Contract”). The Base Contract, together with these Special Provisions, the Transaction Confirmation and any Credit Support form a single agreement
between the parties, collectively, the “Contract”. Except as amended in these Special Provisions, the Base Contract and the General Terms and Conditions remain in full force and effect. All capitalized terms not otherwise defined in these
Special Provisions have the meaning set out in the Base Contract. 
 Any reference to a Section in these Special Provisions refers to the same Section of
the General Terms and Conditions to the Base Contract. 
 Collectively, Seller and Buyer shall be referred to as the “Parties”, and individually
may be referred to as a “Party”. 
 Section 2. Definitions 

The definition of “Credit Support Obligation” in Section 2.13 shall be deleted in its entirety and the following substituted in lieu thereof:

 “Credit Support Obligation(s)” shall mean any obligation(s) to provide or establish credit support for, or on behalf of, a party
to this Contract such as cash, an irrevocable standby letter of credit, a margin agreement, a prepayment, a security interest in an asset, a guaranty, or other good and sufficient security of a continuing nature. The issuer of any such security
and/or the guarantor must be acceptable to the other party at its sole discretion. The other party agrees to act in a reasonable manner in evaluating such issuer and/or guarantor. 

The definition of “Payment Date” in Section 2.27 shall be deleted and replaced with the following: 

“Payment Date” shall mean a date, as indicated on the Base Contract, on or before which payment is due from one Party to the other as
set forth in Section 7.” 
 The definition of “Spot Price” in Section 2.31 shall be amended by deleting the last sentence and
replacing with the following: 
 “If no price or range of prices is published for such Day, then the Spot Price shall be determined in
accordance with Section 14 as modified herein.” 
 Add the following at the end of Section 2: 

“2.36 “Applicable Law” means any foreign, federal, state, tribal or local law, statute, regulation, code, ordinance, license,
permit, compliance requirement, decision, order, writ, injunction, directive, judgment, policy, decree, including any judicial or administrative interpretations thereof, or any agreement, concession or arrangement with any governmental authority,
applicable to either Party or either Party’s performance under a transaction, and any amendments or modifications to the foregoing.

 Section 3. Performance Obligation 

Add the following as new Section 3.5: 

“3.5. Each Party is entering into this Contract in reliance on the Applicable Laws and Taxes in effect on the date hereof. If at any time
after a transaction is entered into: 
 (i) new Applicable Law is enacted, existing Applicable Law is amended, new Taxes are imposed, or
existing Taxes are changed (a “Regulatory Event”), in a way which individually or collectively has a material adverse economic effect upon a party (such party the “Affected Party”) under a particular transaction (each such
transaction an “Affected Transaction”) and which does not constitute a Force Majeure event, then the Affected Party may notify the other party that it desires in good faith to renegotiate the material terms or conditions of the Affected
Transaction(s) in order to address the effects of the Regulatory Event. Such Notice shall state how the Regulatory Event impacts the Affected Transactions and the proposed terms upon which the Affected Party would like to continue to perform the
Affected Transaction(s) with respect to any Gas not yet delivered; or 
 (ii) after giving effect to any applicable provision or remedy
specified in the Contract, it becomes unlawful for a party, (such party the “Affected Party”) under the Applicable Law to perform any material provision in relation the Contract or any particular transaction, (each such transaction an
“Affected Transaction”) (an “Illegality”), then the Affected Party may terminate such Affected Transaction as provided for below. 

If a Regulatory Event occurs and the Parties fail to renegotiate the price or other material terms or conditions within thirty (30) Days
of the Notice, or if an Illegality occurs and such event continues for at least three (3) Business Days, either party shall have the right by Notice to designate a Day, no earlier than the Day such Notice is given and no later than twenty
(20) Days after such Notice is given as the Early Termination Date to terminate and liquidate the Affected Transaction(s). 
 On the
Early Termination Date (i) if there is one Affected Party damages shall be determined in accordance with Section 10 of the Contract, except that references to the Defaulting Party and to the
Non-Defaulting Party will be deemed references to the Affected Party and to the Non-affected Party, or (ii) if there are two Affected Parties, each party shall
determine damages in accordance with Section 10 of the Contract with the Market Value being the arithmetic average of the amounts so determined. The Market Value for each Terminated Transaction shall be determined by using the mid-market quotations or values without regard to the creditworthiness of the party performing the calculations.” 

Section 6. Taxes 
 Section 6 is
amended by adding the following provisions to the end of Section 6: 
 “Gross Receipts and Consumption, and Compensating
Taxes. For clarity, the Contract Price does not include any applicable state or local, gross receipts, compensating, utility, transaction privilege, sales or use tax which may be assessed as a result of sales of or use of Gas hereunder, whether
measured by quantity or revenues (“Gross Receipts” or “Compensating Tax”). If there is such a Gross Receipts and/or Compensating Tax, either of which being applicable to that quantity of Gas sold to or used by Buyer hereunder,
Seller will invoice Buyer and Buyer will pay Seller the amount of the Gross Receipts or Compensating Tax, and Seller will remit same as required by Applicable Law. 

  
 19 

 Protest and Payment. If a Party is required to remit or pay Taxes that are the other
Party’s responsibility hereunder, the Party responsible for such Taxes shall promptly reimburse the other Party for such Taxes, except to the extent either Party has filed, or provides prior notice to the other Party that it will timely file, a
good faith protest, contest, dispute or complaint with the taxing authority or applicable court with jurisdiction, which tolls the requirement to pay such Taxes. Any Party is entitled to make such good faith protests, contests, disputes or
complaints with the applicable taxing authority or applicable court with jurisdiction or to file for a request for refund for such Taxes already paid in a timely manner as to any Taxes that it is responsible to pay or remit or for which it is
responsible to pay or reimburse the other Party. In the event either Party makes such filings, the other Party shall cooperate with such filing Party by providing any relevant information within that Party’s possession, which will support the
filing Party’s filing upon request by and as specified by the filing Party. Upon the issuance by the taxing authority or court of a final, non-appealable order, which lifts the tolling of an obligation to
pay and requires payment of the applicable Taxes, and absent a stay of such order, the responsible Party shall either pay directly to the applicable taxing authority, or reimburse the other Party for, such Taxes and any other amounts (including
interest) required by such order. Any Party entitled to an exemption from any such Taxes or charges shall furnish the other Party any necessary documentation thereof.” 

Section 7. Billing, Payment and Audit 

Section 7.7 is amended by adding the following phrase to the end of the first sentence: 

“provided further, however, that the Party due payment under Section 7.3 may net all undisputed sums due thereunder against any
amounts payable by it when making payments under Section 7.” 
 Section 10. Financial Responsibility 

Section 10.2 is amended by (i) deleting the word “or” before “(ix)” in such Section; and (ii) adding the following
immediately after the “;” at the end of subclause (ix) of such Section: 
 “(x) repudiate, reject or challenge the
validity of, this Contract; (xi) transfer all or substantially all of its assets or merge into or consolidate with any entity or reorganize, incorporate, reincorporate, or reconstitute into or as, another entity, or another entity transfers all
or substantially all its assets to, or reorganizes, incorporates, reincorporates, or reconstitutes into or as, the Defaulting Party where the merging party’s obligations are not assumed by operation of law or written instrument; (xii) have
made any representation or warranty herein which is false or misleading in any material respect when made or when deemed made or repeated; (xiii) fail to perform or breach any other material obligation or covenant under this Contract (except to
the extent such failure constitutes a separate Event of Default, and except for such Party’s obligations to deliver or receive Gas, the exclusive remedy for which is provided in Section 3) if such failure is not remedied within fifteen
(15) Business Days after receipt of written notice.” 
 Section 10.2 is amended by adding the following at the end before the “.”
in the last sentence: 
 “, provided that no suspension of performance shall continue for more than ten (10) Days unless an Early
Termination Date has been declared and the Defaulting Party given Notice thereof in accordance with Section 10.3.” 
 Section 10.3.1 is
amended by adding the following sentence at the end of the first paragraph: 
 “Notwithstanding the foregoing, in no event shall the Non-Defaulting Party owe any amounts to the Defaulting Party on account of this Transaction as a Terminated Transaction, whatever the difference between Market Value and Contract Value. However, nothing in this
section releases Buyer from its obligation to remit any undisputed payment to Seller for any natural gas or Biogas delivered to Buyer pursuant to any Transaction Confirmation.” 

  
 20 

 Delete the words “and without prior Notice to the Defaulting Party” in Section 10.3.2.

 Add the following after the last sentence in each option given for Section 10.3.2: 

“Nothing in this Section will be effective to create a charge or other security interest. This Section will be without prejudice and in
addition to any right of setoff, offset, combination of accounts, lien, right of retention or withholding or similar right or requirement to which a party is at any time otherwise entitled or subject (whether by operation of law, contract or
otherwise).” 
 Section 10.4 is amended by (i) replacing “second” in the sixth line with “fifth,” and (ii) adding
the following at the end thereof: 
 “Notwithstanding the foregoing, if the Non-Defaulting Party
owes the Net Settlement Amount to the Defaulting Party, the obligation of the Non-Defaulting Party to pay to the Defaulting Party the Net Settlement Amount, shall not arise until, and shall be subject to the
condition precedent that, (i) all transactions are terminated in accordance with this Contract and (ii) all obligations (contingent or absolute, matured or unmatured) of the Defaulting Party and any Affiliate of the Defaulting Party to
make any payment to the NonDefaulting Party or any Affiliate of the Non-Defaulting Party shall have been fully and finally performed.” 

Delete Section 10.5 in its entirety and replace it with the following: 

“10.5. “Each Party further represents and warrants to the other Party that (i) this Base Contract and all transaction(s)
governed by the Base Contract constitute “forward contracts” and/or “swap agreements” within the meaning of the United States Bankruptcy Code (the “Code”); (ii) it is a “forward contract merchant” within the
meaning of the Code with respect to any transactions that constitute “forward contracts”; (iii) all payments made or to be made on its behalf pursuant to the Contract, including the application by a Party of any collateral or security to
any amounts due and owing to such Party, constitute “settlement payments” within the meaning of the Code; and (iv) its rights under Section 10, “Financial Responsibility”, of the Contract constitute a “contractual
right to liquidate, terminate, or accelerate” or the transactions within the meaning of the Code. Each Party further agrees that the other Party is not a “utility” as such term is used in 11 U.S.C. Section 366, and each Party
agrees to waive and not to assert the applicability of the provisions of 11 U.S.C. Section 366 in any bankruptcy proceeding involving such Party. In addition, each Party agrees that, for any Gas actually consumed (rather than resold) by such
Party, if Gas is not delivered pursuant to this Contract, the local gas distribution utility for such Party is the provider of last resort and can supply such Party’s Gas consumption needs.” 

Section 11. Force Majeure 
 Delete
Section 11.4 and replace it with the following: 
 “Notwithstanding anything to the contrary in this Section 11, the Parties
agree that the settlement of strikes, lockouts, or other industrial disturbances shall be within the sole discretion of the Party experiencing such disturbance; and further agree that, upon the occurrence and continuance of any event of Force Maj
ewe, neither Party shall be obligated to purchase or sell Gas hereunder if such purchase or sale would result in material economic impact to such Party under the transaction(s) affected by the event of Force Majeure.” 

Add the following as new Section 11.7: 

“11.7 Without restricting the generality of the foregoing, if an event of Force Majeure occurs, the Party affected may, in its sole
discretion and without notice to the other Party, determine not to make a claim of Force Majeure and to waive its rights hereunder as they would apply to such event. Such determination or waiver shall not preclude the affected Party from claiming
Force Majeure in respect of any subsequent event, including any event that is substantially similar to the event in respect of which such determination or waiver is made.” 

  
 Page 21 of 25 

 Add the following as new Section 11.8: 

“11.8 If an event of Force Majeure impairs or prevents Seller from delivering or Buyer from purchasing Gas under this Contract and such
event of Force Majeure continues (i) for a continuous period of time greater than ninety (90) Days or (ii) for more than one hundred and eighty (180) cumulative Days during any calendar year, the Party not claiming the event of
Force Majeure may terminate and liquidate the transactions affected by such event of Force Majeure utilizing the same methodology (including rights and remedies) set forth under Section 3. Notwithstanding the foregoing, (a) if the Party
claiming an event of Force Majeure proceeded with reasonable efforts to resolve the event or occurrence once it occurred in order to resume performance but performance under the Contract cannot resume until after the time periods set forth in (i),
the Party not claiming the event of Force Majeure may not terminate and liquidate the transactions affected by such event of Force Majeure unless performance is not resumed within one hundred and eighty (180) Days from the event of Force
Majeure; and (b) to the extent the event of Force Majeure relates to the events described in any of the events described in (i)-(iii) of Section 11.2, any affected transactions shall be terminated between the Parties without either Party
being liable to the other Party for any damages under the Contract except for indemnification obligations.” 
 Section 12. Term

 Delete the second sentence and replace it with the following: 

“The rights of either Party pursuant to: (i) Section 7, (ii) Section 10, (iii) Section 13, (iv) Section 14, (v)
Section 15, (vi) Waiver of Jury Trial provisions (if applicable), (vii) the obligations to make payment hereunder, and (viii) the obligation of either Party to indemnify the other pursuant hereto, shall survive the termination of the Base
Contract or any transaction.” 
 Section 14. Market Disruption 

Delete Section 14 and replace it with the following: 

“If a Market Disruption Event has occurred then the Parties shall negotiate in good faith to agree on a replacement price for the Floating
Price (or on a method for determining a replacement price for the Floating Price) for the affected Day, and if the Parties have not so agreed on or before the second Business Day following the affected Day then the replacement price for the Floating
Price shall be determined within the next two following Business Days with each Party attempting to obtain, in good faith and from non-affiliated market participants in the relevant market, at least four
quotes for prices of Gas for the affected Day of a similar quality and quantity in the geographical location closest in proximity to the Delivery Point and averaging the four quotes, Once the Parties obtain the quotes, the following methodology
shall be used to determine the replacement price for the Floating Price: (i) if each Party obtains four or more quotes, the arithmetic mean of the quotations, excluding the highest and lowest values, shall be utilized; (ii) if one Party
obtains four or more quotes and the other Party obtains less than four, the highest and lowest values of all obtained quotes shall be excluded and the arithmetic mean of the remaining quotations shall be utilized; or (iii) if both Parties
obtain less than four quotes, the Parties shall resort to the negotiation process set out in Section 15.16 to resolve the dispute with the quotes being only indicative of an illiquid market which shall allow both Parties to utilize other
industry information, including internal valuations to resolve the dispute. For purposes of the foregoing sentence, if more than one quotation is the same as another quotation, and such quotations are the highest and/or lowest values, only one of
the quotations shall be excluded. “Floating Price” means the price or a factor of the price agreed to in the transaction as being based upon a specified index. “Market Disruption Event” means, with respect to an index specified
for a transaction, any of the following events: (a) the failure of the index to announce or publish information necessary for determining the Floating Price; (b) the failure of trading to commence or the permanent discontinuation or
material suspension of trading on the exchange or market acting as the index; (c) the temporary or permanent discontinuance or unavailability of the index; (d) the temporary or permanent closing of

  
 Page 22 of 25 

 
any exchange acting as the index; or (e) a material change in the formula for or the method of determining the Floating Price has occurred. For the purposes of the calculation of a
replacement price for the Floating Price, all numbers shall be rounded to three decimal places. If the fourth decimal number is five or greater, then the third decimal number shall be increased by one and if the fourth decimal number is less than
five, then the third decimal number shall remain unchanged.” 
 Section 15. Miscellaneous 

Delete Section 15.3 in its entirety and replace it with the following: 

“15.3 No waiver of any breach of this Contract, or delay, failure or refusal to exercise or enforce any rights under this Contract
(including any rights to claim excused performance as a result of an event of Force Majeure), shall be held to be a waiver of any other or subsequent breach, or be construed as a waiver of any such right then existing or arising in the future.”

 Section 15.5 is amended by inserting the following at the end thereof: 

“In the event judicial proceedings are instituted by either Party for the enforcement of this Contract or any provisions hereof, the
prevailing Party shall be entitled to award of its reasonable costs and attorneys’ fees incurred in connection with such proceedings.” 
 Add the
following as new Section 15.13: 
 “15.13 To the extent, if any, that a transaction does not qualify as a “first sale” as
defined by the Natural Gas Act and §§ 2 and 601 of the Natural Gas Policy Act, each Party irrevocably waives its rights, including its rights under §§ 4-5 of the Natural Gas Act,
unilaterally to seek or support a change to any terms and conditions of the Contract, including but not limited to the rate(s), charges, or classifications set forth therein. By this provision, each Party expressly waives its right to seek or
support, either directly or indirectly, and by whatever means: (i) an order from the U.S. Federal Energy Regulatory Commission (“FERC”) seeking to change any of the terms and conditions of the Contract agreed to by the Parties; and
(ii) any refund from the other Party with respect to the Contract. Each Party further agrees that this waiver and covenant shall be binding upon it notwithstanding any regulatory or market changes that may occur after the date of the Base
Contract or any transaction entered into between the Parties. Absent the agreement of both Parties to the proposed change, the standard of review for changes to any terms and conditions of the Contract proposed by (a) a Party, to the extent
that the waiver set forth in this Section 15.13 is unenforceable or ineffective as to such Party due to a final determination being made under applicable law that precludes the Party from waiving its rights to seek or support changes from the
FERC to the terms and conditions of this Contract, (b) a non-party, or (c) the FERC acting sua sponte, shall solely be the “public interest” application of the “just and
reasonable” standard of review set forth in United Gas Pipe Line Co. v. Mobile Gas Service Corp., 350 U.S. 332 (1956) and Federal Power Commission v. Sierra Pacific Power Co., 350 U.S. 348 (1956) (the “Mobile-Siena”), as
Mobile-Siena has been clarified by Morgan Stanley Capital Group, Inc, v. Public Util. Dist. No. 1 of Snohomish, 128 S.Ct. 2733 (2008), and NRG Power Marketing, LLC v. Maine Public Utilities Commission,
130.S.Ct.” 693 (2010).” 
 Add the following as new Section 15.14: 

“15.14 This Contract shall be considered for all purposes as prepared through the joint efforts of the Parties and shall not be construed
against one Party or the other as a result of the manner in which this Contract was negotiated, prepared, drafted or executed.” 

  
 Page 23 of 25 

 Add the following as new Section 15.15: 

“15.15 Each Party will be deemed to represent to the other Party each time a transaction is entered into that: (i) it is acting for
its own account, and it has made its own independent decisions to enter that transaction and as to whether that transaction is appropriate or proper for it based upon its own judgment and upon advice from such advisors as it has deemed necessary;
(ii) it is not relying on any communication (written or oral) of the other Party as investment advice or as a recommendation to enter into that transaction; it being understood that information and explanations related to the terms and
conditions of a transaction shall not be considered investment advice or a recommendation to enter into that transaction; (iii) no communication (written or oral) received from the other Party shall be deemed to be an assurance or guarantee as
to the expected results of that transaction; (iv) it is capable of assessing the merits (on its own behalf or through independent professional advice), and understands and accepts, the terms, conditions and risks of that transaction;
(v) it is capable of assuming, and assumes, the risks of that transaction; and (vi) the other Party is not acting as a fiduciary for, or an advisor to, it in respect of that transaction.” 

Add the following as new Section 15.16: 

“15.16 The Parties covenant and agree to comply with all Applicable Laws, rules and regulations associated with any Transaction.”

 Add the following as new Section 15.17: 

“15.17. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER
BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR IN ANY WAY RELATING TO THIS CONTRACT OR THE PERFORMANCE OR NONPERFORMANCE OF OBLIGATIONS ARISING UNDER OR IN CONNECTION WITH THIS CONTRACT.” 

The Parties represent and warrant that the General Terms and Conditions of the Base Contract have not been modified, altered, or amended in any respect except
for (i) these Special Provisions and (ii) as explicitly set forth in the Transaction Confirmation.
