 Maximum Daily Volume ("MDV"): MDV is the maximum amount of RNG produced by the Project that will be sold to Buyer and the amount of
transportation capacity that will be deducted from the fixed price. MDV shall be equal to the volumes set forth in the Table
below. Notwithstanding anything contained herein to the contrary, until the successful permitting, construction and commencement of commercial operation of an expansion to the existing gas processing
facility that is part of the Project to at least 15 million standard cubic feet per day inlet capacity of raw landfill gas, the MDV shall be equal to 4500 MMBtu/day; provided however, that no
increases from the 4500 MMBtu/day MDV will be effective unless Seller has given Buyer eight Months' prior written notice of the expected commencement date of the expansion. 

Buyer
and Seller agree that irrespective of actual gas volumes delivered under this Transaction Confirmation that Seller is fully responsible for all EPNG Firm Monthly Reservation Charges for the MDV
capacity for the entire Delivery Period to the extent that such EPNG capacity has been contracted by Buyer. 

 Seller's and Buyer's Firm Obligation: Seller agrees to deliver to Buyer and Buyer agrees to purchase, on a daily Firm basis, all RNG produced from the Project up
to the MDV, except for (a) and (b) below. 

 Table:

	 	6000 MMBtu per day

	a.
	RNG
actually consumed in the process ("Consumed RNG") of making raw landfill gas pipeline quality is excluded from this transaction when total Project daily
RNG production is less than or equal to the sum of MDV plus Consumed RNG. When total Project daily RNG production is greater than the sum of MDV plus Consumed RNG, Buyer shall get the full MDV.

	b.
	On
sixty (60) days' prior written notice to Buyer, DCE may elect to reserve (and thus reduce MDV) up to 500 MMBtu's of daily production for use or
sale as a vehicle fuel, in connection with any agreement between DCE or any DCE affiliate with the City of Dallas or other refuse collection fleet, provided that Buyer shall have the right to request
the associated meter data to validate the amounts reduced from production. Seller agrees to provide said meter data to Buyer promptly. 

In
the event the actual RNG volumes for an entire year average less than 50% of the MDV, then upon receipt of written request from Buyer, Buyer and Seller will meet for the purpose of discussing
whether it is appropriate to adjust the MDV. 

"PPT" mean Pacific Prevailing Time. 

"Project" means Seller's McCommas Bluff Landfill Gas Processing Facility in Dallas, Texas. 

"Renewable Natural Gas" ("RNG") means Gas production from the Project that: 

(i)  consists
of pipeline-quality Landfill Gas, as that term is defined in the California Energy Commission's ("CEC") Renewable Energy Program Overall Program Guidebook (January 2008); and 

(ii)  contains
all the environmental attributes associated with the use of a pipeline quality Landfill Gas-derived fuel for the generation of electric power, but excluding
(a) any federal or state tax credits associated with the collection, production, transfer or sale of such Landfill Gas (unless an amount equal to 115% of such tax credits are added to the
purchase price for the Renewable Natural Gas and paid as earned), (b) any emission reduction credits required or available for the operation of a Landfill Gas processing facility at the
Landfill to convert collected Landfill Gas to pipeline quality gas standards, and (c) any credits or payments associated with the reduction in or avoidance of Greenhouse Gas emissions at the
Landfill, 

	***

including
emission reduction credits, verified emission reductions, voluntary emission reductions, offsets, allowances, voluntary carbon units, avoided compliance costs, emission rights and
authorizations, and CO2 reduction and sequestration. For purposes hereof, "Greenhouse Gas" means carbon dioxide (CO2), methane (CH4), nitrous oxide
(N2O), hydrofluorocarbons, perfluorocarbons, sulphur hexafluoride, or any other substance or combination of substances that may become regulated or designated as Greenhouse Gases under any
federal, state or local law or regulation, or any emission reduction registry, trading system, or reporting or reduction program for Greenhouse Gas emission reductions that is established, certified,
maintained, or recognized by any international, governmental (including U.N., federal, state, or local agencies), or non-governmental agency from time to time, in each case measured in
increments of one metric tonne of carbon dioxide equivalent. 

(iii).  Seller represents and warrants that all gas scheduled hereunder for purchase by Buyer shall be RNG Gas. Notwithstanding the
foregoing, Seller shall transfer and assign or cause to be transferred and assigned without additional cost to Buyer such number of GHG emission reduction credits whether from the Project or a
comparable number of such credits from another source, as may be reasonably required, as determined by the CEC or other applicable regulatory authority, to achieve zero net emissions associated with
the kilowatt hours of electricity attributable to the use of the RNG supplied by Seller to be utilized by Buyer in its multi-fuel generating facility that meets the eligibility standards
for certification under the CEC's Renewables Portfolio Standard Eligibility Guidebook, (Third Edition, January 2008) or successor standards. To implement this transfer, Buyer shall provide to Seller
at least 30 days notice, requesting Seller to transfer the specified number of required GHG emission reduction credits together with an explanation of why such GHG reduction credits will be
required to achieve zero net emissions with respect to the kilowatt-hours anticipated to be produced using the RNG sold by Seller hereunder. Seller will transfer or cause the transfer of GHG emission
reduction credits as soon as reasonably practicable. 

"Surplus Daily Capacity" ("SDC") means any excess unutilized volumes of Buyer's EPNG transportation
capacity resulting from the difference between the applicable MDV and the gas volumes actually nominated for a given gas day. 

 Term: Buyer shall have the exclusive right for the first 45 days of the last 60 day period of the initial Delivery Period to negotiate an extension
of this Transaction at terms mutually agreeable to Buyer and Seller if at that end of the Delivery Period DCE has at least 5 years remaining on the term of the Landfill Gas Lease with the City
of Dallas that is part of the Project that is not subject to any right of termination, for convenience or otherwise, in favor of the City of Dallas. 

 Contract Price:  

As part of the pricing formulas and volume terms and conditions below the Fixed Price component
is: 

	•
	[***] per MMBtu for April to December 2009  
	•
	[***] per MMBtu for January to December 2010  
	•
	[***] per MMBtu for January 2011 to March 2024 

 Contract Price for actual gas volumes delivered by Seller to Buyer:  

Buyer shall pay Seller the Fixed Price per MMBtu multiplied by the actual volume of MMBtus delivered less 

the
EPNG Firm Monthly Reservation Charge multiplied by the MDV and less 

the
EPNG variable charges and a Determined Value for fuel losses* multiplied by the actual daily volumes.  

	*
	For
purposes hereof, the Determined Value for fuel losses shall be equal to a "monetized value" for fuel losses equal to the percentage set forth in the then
applicable tariff of EPNG of actual daily volumes measured each day in MMBtus for fuel losses multiplied by the Gas Daily Permian Basin midpoint price. 

During
the Delivery period hereof, upon Seller's request, Buyer will convert the fuel formula above from a "monetized value" to an "in-kind" process based on the applicable EPNG tariff, (a
reduction in volume equivalent to the fuel charges), if there are no regulatory limitations to such conversion. 

As a 2009 daily illustrative example on a day with actual volumes delivered to Buyer of 3100 MMBtus, assuming EPNG charges are the following:

 Optimization of Surplus Daily Capacity and Pricing:  

Buyer shall provide optimization services to Seller for the Surplus Daily Capacity. Buyer and Seller shall share in equal positive values extracted
from this optimization calculated as follows: 

"Market Spread" means Gas Daily PG&E South midpoint minus Gas Daily El Paso Permian Basin midpoint 

"EPNG Variable Charges" consist of Base Usage, Surcharges and Fuel 

If
Market Spread is greater than EPNG Variable Charges then: 

Buyer
shall credit to Seller Fifty percent (50%) of the difference between Market Spread less EPNG Variable Charges; multiplied by the Surplus Daily Capacity. 

As a 2009 daily illustrative example, assuming that the Market Spread is $1.00/MMBtu and the SDC is 200 MMBtu consistent with the pricing example above and EPNG Variable
Charges are the following:

 Damages for Intra-Day Volume Changes.  

The following damages shall constitute "Alternative Damages" to be effective in lieu of Section 3.2 of the Base
Contract for the purposes of this Confirmation:

Seller
shall be responsible for costs to Buyer associated with intra-day volume changes according to the following formula: 

If
Actual Volume Produced is greater than Nominated Volume, then (El Paso Permian Basin midpoint minus El Paso Permian Basin Absolute Low) * (Actual Volume Produced minus Nominated Volume) 

If
Actual Volume Produced is less than Nominated Volume (El Paso Permian Basin Absolute High minus El Paso Permian Basin midpoint) * (Nominated Volume minus Actual Volume Produced) 

As an illustrative example, assuming the following Gas Daily prices on any one day:

												
	Permian

Abs High 	 	Permian

Abs Low 	 	Permian

Midpoint 	 	Volume

Nominated 	 
	 	6.78	 	 	6.56	 	 	6.64	 	 	1,000	 

If
Actual Volume Produced was 1,500 MMBtu/day, then (6.64 - 6.56) * (1,500 - 1,000) = $40 due from Seller to Buyer for the day. 

If
Actual Volume Produced was 500 MMBtu/day, then (6.78 - 6.64) * (1,000 - 500) = $70 due from Seller to Buyer for the day. 

 Agency Agreement on Atmos Pipeline. Buyer agrees to be Seller's agent for purposes of scheduling and invoicing on the Atmos Pipeline and gathering system.
Imbalances on Atmos Pipeline shall remain the financial responsibility of Seller but Buyer agrees to act on Seller's behalf to minimize any adverse impacts to the extent commercially and reasonably
possible. The Parties agree to work out a mutually agreeable arrangement on credit for associated Atmos charges. For example, Seller may post a deposit of one month's average Atmos Pipeline charges
with Buyer in order to enable Buyer to pay Atmos on Seller's behalf. Such charges shall then be deducted from Seller's monthly revenue. 

 Early Termination of this Transaction Confirmation:  

	a.
	Each
party hereto shall have the right to terminate this Transaction Confirmation upon 30 days' written notice given to the other party hereto if the
California Energy Commission makes a written determination or adopts a ruling or regulation after the date of the Base Contract and this Transaction Confirmation that the RNG subject to this
Transaction Confirmation and the Base Contract will from the date of such ruling or regulation no longer qualify as a California Renewable Portfolio Standard eligible fuel. Specifically such ruling or
regulation by the California Energy Commission must be sufficiently specific so as to clearly apply to the Base Contract and the Transaction Confirmation and the RNG to be delivered and sold
thereunder and not merely to renewable natural gas that is similar to or the same as the RNG, but that is not subject to a binding contract at the time that the California Energy Commission issues its
ruling or regulation.

	b.
	Buyer
shall have the right at its sole discretion to terminate this Transaction Confirmation upon 30 days' notice to Seller if the volumes of RNG gas
scheduled and delivered, calculated monthly on a rolling two-year average, are less than an annual average of 630,720 MMBtu per year (2,083 MMBtu per day) measured at the Project
interconnect with the Atmos pipeline system.

 Consent to Collateral Assignment:  

Subject to the provisions hereunder, Seller shall have the right to assign this Agreement as collateral for any financing or refinancing of the gas
processing facility located at the McCommas Bluff Landfill in Dallas, Texas and any replacements or expansions thereto, the collection system and any related equipment and contractual rights (the
"Project"). 

In
connection with any financing or refinancing of the Project by Seller, Buyer shall in good faith work with Seller and Lender to agree upon a consent to collateral assignment of this Agreement
("Collateral Assignment Agreement"); provided, however, if Seller and Lender are unable to reach agreement on the terms of such Collateral Assignment Agreement within sixty (60) days from the
commencement of negotiations thereon, Seller shall have the right to terminate this Agreement upon the giving of written notice to Buyer. 

The
Collateral Assignment Agreement shall be in form and substance agreed to by Buyer, Seller and Lender, and shall include, among others, the following provisions: 

	(a)
	Buyer
shall give Notice of an Event of Default by Seller, to the person(s) to be specified by Lender in the Collateral Assignment Agreement, and shall
provide Lender with a reasonable period of time to cure any such Event of Default or, if additional rights are needed by Lender to effectuate such cure, to gain sufficient rights from Seller to allow
Lender to cure such Event of Default prior to exercising its right to terminate this Agreement as a result of such Event of Default;

	(b)
	Lender
shall have the right to cure an Event of Default on behalf of Seller, only if Lender sends a written notice to Buyer prior to the end of any cure
period including any extended cure period provided to Lender, indicating Lender's intention to cure. Lender must remedy or cure the Event of Default within the cure period under the Collateral
Assignment Agreement; provided that, if such cure cannot be completed within the applicable cure period, then such cure must have been commenced within such cure period and diligently pursued to
completion;

	(c)
	Cure
periods for monetary defaults shall not exceed 15 days from the date the Lender is given Notice, and Buyer can give notice contemporaneously
with the Notice given to Seller;

	(d)
	Cure
periods for non-monetary defaults, other than an event of Seller's bankruptcy, shall, subject to the provisions of subparagraph (b)
above, not exceed 60 days from the receipt of notice by Lender, and Buyer can give notice contemporaneously with the Notice given to Seller;

	(e)
	Cure
periods in the event Seller becomes bankrupt, other than involuntary bankruptcy, shall be no longer than 30 days. Cure periods in the event
Seller has an involuntary bankruptcy proceeding filed against it, shall be no longer than 60 days;

	(f)
	Buyer,
Seller, and Lender shall agree that, subject to Buyer's compliance with the notice, written consent and cure rights of Lender set forth herein,
nothing herein shall waive Buyer's right to terminate this Transaction Confirmation or will prevent the Transaction Confirmation from expiring on its own terms;

	(g)
	Buyer
shall not be obligated to provide Lender with an opinion of counsel, but shall, if requested by Lender or Seller, timely provide Lender with an
estoppel certificate with respect to this Agreement on terms reasonably requested by Lender or Seller;

	(h)
	Lender
shall have the right to receive notice prior to any termination of this Agreement which does not arise out of an Event of Default, and Buyer shall
not enter into any agreement of mutual termination of this Agreement without providing such notice to Lender;

	(i)
	Lender
shall receive prior Notice of and the right to approve material amendments to this Agreement, which approval shall not unreasonably be withheld,
delayed or conditioned, but in any event such approval will be deemed to have been given if no objection from Lender is received by Buyer within 15 Business Days after notice of any intent to amend;

	(j)
	In
the event Lender, directly or indirectly, takes possession of, or title to the Project other than through a lease entered into solely for purposes of
providing financing to Seller for all or any part of the Project (including possession by a receiver or title by foreclosure or deed in lieu of foreclosure), Lender shall assume all of Seller's
obligations arising under this Agreement and all related agreements for only the period of time during which Lender has taken such possession (subject to such limits on liability as are mutually
agreed to by Seller, Buyer and Lender as set forth in the Collateral Assignment Agreement);

provided that, Lender shall have no personal liability for (i) any monetary obligations of Seller under this Agreement which are due and owing to
Buyer as of the assumption date, (ii) or that arise following any assignment of this Agreement and the assumption of its obligations by an assignee from Lender pursuant to the rights granted to
Lender in any Collateral Assignment Agreement; provided further, however, that prior to such assumption, if Buyer advises Lender that Buyer will require
that Lender cure (or cause to be cured) any Event of Default existing as of the possession date as to which the Lender has the power to cure, in order to avoid the exercise by Buyer (in its sole
discretion) of Buyer's right to terminate this Agreement with respect to such Event of Default, then Lender at its option, and in its sole discretion,
may elect to either: 

	(i)
	Cause
such Event of Default to be cured, or

	(ii)
	Not
assume this Agreement;

	(k)
	If
Lender elects to sell or transfer the Project (after Lender directly or indirectly, takes possession of, or title to the Project), or sale of the Project
occurs through the actions of Lender (for example, a foreclosure sale where a third party is the buyer, or otherwise), then Lender must cause the
transferee or buyer to assume all of Seller's obligations, and cure all defaults susceptible to being cured, arising under this Agreement and all related agreements as a condition of the sale or
transfer. Such sale or transfer may be made only to an entity with financial qualifications and operating experience (whether directly or through a contract with an experienced operations and
maintenance contractor) reasonably equivalent to Seller as of the Effective Date; and

  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 2.7. 

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. However, nothing herein shall be construed as a waiver of any objection to the admissibility of such evidence.

nonperforming party.

sole and exclusive remedy of the parties in the event of a breach of a Firm obligation to deliver or receive Gas shall be recovery of the following: (i) in the event of a
breach by Seller on any Day(s), payment by Seller to Buyer in an amount equal to the difference between the Contract Quantity and the actual quantity delivered by Seller and received by Buyer for such

to Seller in an amount equal to the difference between the Contract Quantity and the actual quantity delivered by Seller and received by Buyer for such Day(s), multiplied by the positive difference,
if any, obtained by subtracting the applicable Spot Price from the Contract Price. Imbalance Charges shall not be recovered under this Section 3.2, but Seller and/or Buyer shall be responsible
for Imbalance Charges, if any, as provided in Section 4.3. The amount of such unfavorable difference shall be payable five Business Days after presentation of the performing party's invoice,
which shall set forth the basis upon which such amount was calculated. 

3.3.  Notwithstanding
Section 3.2, the parties may agree to Alternative Damages in a Transaction Confirmation executed in writing by both parties. 

3.4.  In
addition to Sections 3.2 and 3.3, the parties may provide for a Termination Option in a Transaction Confirmation executed in writing by both parties. The Transaction
Confirmation containing the Termination Option will designate the length of nonperformance triggering the Termination Option and the procedures for exercise thereof, how damages for nonperformance
will be compensated, and how liquidation costs will be calculated. 

SECTION 4.    TRANSPORTATION, NOMINATIONS, AND IMBALANCES    

4.1.  Seller
shall have the sole responsibility for transporting the Gas to the Delivery Point(s). Buyer shall have the sole responsibility for transporting the Gas from the Delivery

prior Notice, sufficient to meet the requirements of all Transporter(s) involved in the transaction, of the quantities of Gas to be delivered and purchased each Day. Should either party become aware
that actual deliveries at the Delivery Point(s) are greater or lesser than the Scheduled Gas, such party shall promptly notify the other party. 

4.3.  The
parties shall use commercially reasonable efforts to avoid imposition of any Imbalance Charges. If Buyer or Seller receives an invoice from a Transporter that includes Imbalance
Charges, the parties shall determine the validity as well as the cause of such Imbalance Charges. If the Imbalance Charges were incurred as a result of Buyer's receipt of quantities of Gas greater
than or less than the Scheduled Gas, then Buyer shall pay for such Imbalance Charges or reimburse Seller for such Imbalance Charges paid by Seller. If the Imbalance Charges were incurred as a result
of Seller's delivery of quantities of Gas greater than or less than the Scheduled Gas, then Seller shall pay for such Imbalance Charges or reimburse Buyer for such Imbalance Charges paid by Buyer. 

SECTION 5.    QUALITY AND MEASUREMENT    

All
Gas delivered by Seller shall meet the pressure, quality and heat content requirements of the Receiving Transporter. The unit of quantity measurement for purposes of this Contract shall be one
MMBtu dry. Measurement of Gas quantities hereunder shall be in accordance with the established procedures of the Receiving Transporter. 

6

 

SECTION 6.    TAXES    

The parties have selected either "Buyer Pays At and After Delivery Point" or "Seller Pays Before and At Delivery Point" as indicated on the Base
Contract.

 Buyer Pays At and After Delivery Point:  

Seller shall pay or cause to be paid all taxes, fees, levies, penalties, licenses or charges imposed by any government authority ("Taxes") on or with
respect to the Gas prior to the Delivery Point(s). Buyer shall pay or cause to be paid all Taxes on or with respect to the Gas at the Delivery Point(s) and all Taxes after the Delivery Point(s). 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. Any party entitled to an exemption from any such Taxes or charges shall furnish the other party any necessary
documentation thereof. 

 Seller Pays Before and At Delivery Point:  

Seller shall pay or cause to be paid all taxes, fees, levies, penalties, licenses or charges imposed by any government authority ("Taxes") on or with
respect to the Gas prior to the Delivery Point(s) and all Taxes at the Delivery Point(s). Buyer shall pay or cause to be paid all Taxes on or with respect to the Gas after the Delivery Point(s). 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. 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    

7.1.  Seller
shall invoice Buyer for Gas delivered and received in the preceding Month and for any other applicable charges, providing supporting documentation 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 Day, payment is due on the next Business Day following that date. In the event any Payments are due
Buyer hereunder, payment to Buyer shall be made in accordance with this Section 7.2. 

7.3.  In
the event payments become due pursuant to Sections 3.2 or 3.3, the performing party may submit an invoice to the nonperforming party for an accelerated payment setting
forth the basis upon which the invoiced amount was calculated. Payment from the nonperforming party will be due five Business Days after receipt of invoice. 

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. In the event the parties are
unable to resolve such dispute, either party may pursue any remedy available at law or in equity 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 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. 

7.6.  A
party shall have the right, at its own expense, upon reasonable Notice and at reasonable times, to examine and audit and to obtain copies of the relevant portion of the books,
records, and telephone recordings of the other party only to the extent reasonably necessary to verify the accuracy of any statement, charge, payment, or computation made under the Contract. This
right to examine, 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 shall make a single payment of the net amount to the other party in accordance with Section 7; provided
that no payment required to be made pursuant to the terms of any Credit Support Obligation or pursuant to Section 7.3 shall be subject to netting under this Section. If the parties have
executed a separate netting agreement, the terms and conditions therein shall prevail to the extent inconsistent herewith. 

7

 

SECTION 8.    TITLE, WARRANTY, AND INDEMNITY    

8.1.  Unless
otherwise specifically agreed, title to the Gas shall pass from Seller to Buyer at the Delivery Point(s). Seller shall have responsibility for and assume any liability with
respect to the Gas prior to its delivery to Buyer at the specified Delivery Point(s). Buyer shall have responsibility for and any liability with respect to said Gas after its delivery to Buyer at the
Delivery Point(s). 

8.2.  Seller
warrants that it will have the right to convey and will transfer good and merchantable title to all Gas sold hereunder and delivered by it to Buyer, free and clear of all
liens, encumbrances, and claims. EXCEPT AS PROVIDED IN THIS SECTION 8.2 AND IN SECTION 14.8, ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING ANY WARRANTY OF MERCHANTABILITY OR OF
FITNESS FOR ANY PARTICULAR PURPOSE, ARE DISCLAIMED. 

8.3.  Seller
agrees to indemnify Buyer and save it harmless from all losses, liabilities or claims including reasonable attorneys' fees and costs of court ("Claims"), from any and all
persons, arising from or out of claims of title, personal injury or property damage from said Gas or other charges thereon which attach before title passes to Buyer. Buyer agrees to indemnify Seller
and save it harmless from all Claims, from any and all persons, arising from or out of claims regarding payment, personal injury or property damage from said Gas or other charges thereon which attach
after title passes to Buyer. 

8.4.  Notwithstanding
the other provisions of this Section 8, as between Seller and Buyer, Seller will be liable for all Claims to the extent that such arise from the failure of Gas
delivered by Seller to meet the quality requirements of Section 5. 

SECTION 9.    NOTICES    

9.1.  All
Transaction Confirmations, invoices, payments and other communications made pursuant to the Base Contract ("Notices") shall be made to the addresses specified in writing by the
respective parties from time to time. 

9.2.  All
Notices required hereunder may be sent by facsimile or mutually acceptable electronic means, a nationally recognized overnight courier service, first class mail or hand
delivered. 

9.3.  Notice
shall be given when received on a Business Day by the addressee. In the absence of proof of the actual receipt date, the following presumptions will apply. Notices sent by
facsimile shall be deemed to have been received upon the sending party's receipt of its facsimile machine's confirmation of successful transmission. If the day on which such facsimile is received is
not a Business Day or is after five p.m. on a Business Day, then such facsimile shall be deemed to have been received on the next following Business Day. Notice by overnight mail or courier
shall be deemed to have been received on the next Business Day after it was sent or such earlier time as is confirmed by the receiving party. Notice via first class mail shall be considered delivered
five Business Days after mailing. 

SECTION 10.    FINANCIAL RESPONSIBILITY    

10.1.  If
either party ("X") has reasonable grounds for insecurity regarding the performance of any obligation under this Contract (whether or not then due) by the other party ("Y")
(including, without limitation, the occurrence of a material change in the creditworthiness of Y), X may demand Adequate Assurance of Performance. "Adequate Assurance of Performance" shall mean
sufficient security in the form, amount and for the term reasonably acceptable to X, including, but not limited to, a standby irrevocable letter of credit, a prepayment, a security interest in an
asset or a performance bond or guaranty (including the issuer of any such security). 

10.2.  In
the event (each an "Event of Default") either party (the "Defaulting Party") or its guarantor shall: (i) make an assignment or any general arrangement for the benefit of
creditors; (ii) file a petition or otherwise commence, authorize, or acquiesce in the commencement of a proceeding or case under any bankruptcy or similar law for the protection of
creditors or have such petition filed or proceeding commenced against it; (iii) otherwise become bankrupt or insolvent (however evidenced); (iv) be unable to pay its debts as they fall
due; (v) have a receiver, provisional liquidator, conservator, custodian, trustee or other similar official appointed with respect to it or substantially all of its assets; (vi) fail to
perform any obligation to the other party with respect to any Credit Support Obligations relating to the Contract, (vii) fail to give Adequate Assurance of Performance under Section 10.1
within 48 hours but at least one Business Day of a written request by the other party; or (viii) not have paid any amount due the other party hereunder on or before the second Business
Day following written Note that such payment is due; then the other party (the "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. 

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 or that are, in the reasonable opinion of the Non-Defaulting Party, commercially impracticable to liquidate and terminate
("Excluded Transactions"), which Excluded Transactions must be liquidated and terminated as soon thereafter as is reasonably practicable, 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. 

8

 

 The parties have selected either "Early Termination Damages Apply" or "Early Termination Damages Do Not 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. 

The parties have selected either "Other Agreement Setoffs Apply" or "Other Agreement Setoffs Do Not Apply" as indicated on the Base Contract.

 Other Agreement Setoffs 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 (i) any Net Settlement Amount owed to the Non-Defaulting Party against any margin or other collateral held by it in connection
with any Credit Support Obligation relating to the Contract; or (ii) any Net Settlement Amount payable to the Defaulting Party against any amount(s) payable by the Defaulting Party to the
Non-Defaulting Party under any other agreement or arrangement between the parties. 

 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 owed to the Non-Defaulting Party against any margin or other collateral held by it in connection with any
Credit Support Obligation relating to the Contract. 

9

 

        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 such 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 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 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. 

10.5.  The
parties agree that the transactions hereunder constitute a "forward contract" within the meaning of the United States Bankruptcy Code and that Buyer and Seller are each "forward
contract merchants" within the meaning of the United States Bankruptcy Code. 

10.6.  The
Non-Defaulting Party's remedies under this Section 10 are the sole and exclusive remedies of the Non-Defaulting Party with respect to the
occurrence of any Early Termination Date. Each party reserves to itself all other rights, setoffs, counterclaims and other defenses that it is or may be entitled to arising 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; 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 (iii) economic hardship, to include, without limitation, Seller's ability to sell Gas at a
higher or more advantageous price than the Contract Price, Buyer's 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 Agreement; (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 Seller's gas supply or depletion of reserves, except, in either case, as provided In Section 11.2. The party claiming Force
Majeure shall not be excused from its responsibility for Imbalance Charges. 

11.4.  Notwithstanding
anything to the contrary herein, 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. 

10

 

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. 

11.6.  Notwithstanding
Sections 11.2 and 11.3, the parties may agree to alternative Force Majeure provisions in a Transaction Confirmation executed in writing by both parties. 

SECTION 12.    TERM    

This
Contract may be terminated on 30 Days written Notice, but shall remain in effect until the expiration of the latest Delivery Period of any transaction(s). The rights of either party pursuant to
Section 7.6 and Section 10, the obligations to make payment hereunder, and the obligation of either party to indemnify the other, pursuant hereto shall survive the termination of the
Base Contract or any transaction. 

SECTION 13.    LIMITATIONS    

FOR
BREACH OF ANY PROVISION FOR WHICH AN EXPRESS REMEDY OR MEASURE OF DAMAGES IS PROVIDED, SUCH EXPRESS REMEDY OR MEASURE OF DAMAGES SHALL BE THE SOLE AND EXCLUSIVE REMEDY. A PARTY'S LIABILITY
HEREUNDER SHALL BE LIMITED AS SET FORTH IN SUCH
PROVISION, AND ALL OTHER REMEDIES OR DAMAGES AT LAW OR IN EQUITY ARE WAIVED. IF NO REMEDY OR MEASURE OF DAMAGES IS EXPRESSLY PROVIDED HEREIN OR IN A TRANSACTION, A PARTY'S LIABILITY SHALL BE LIMITED
TO DIRECT ACTUAL DAMAGES ONLY. SUCH DIRECT ACTUAL DAMAGES SHALL BE THE SOLE AND EXCLUSIVE REMEDY, AND ALL OTHER REMEDIES OR DAMAGES AT LAW OR IN EQUITY ARE WAIVED. UNLESS EXPRESSLY HEREIN PROVIDED,
NEITHER PARTY SHALL BE LIABLE FOR CONSEQUENTIAL, INCIDENTAL, PUNITIVE, EXEMPLARY OR INDIRECT DAMAGES, LOST PROFITS OR OTHER BUSINESS INTERRUPTION DAMAGES, BY STATUTE, IN TORT OR CONTRACT, UNDER ANY
INDEMNITY PROVISION OR OTHERWISE. IT IS THE INTENT OF THE PARTIES THAT THE LIMITATIONS HEREIN IMPOSED ON REMEDIES AND THE MEASURE OF DAMAGES BE WITHOUT REGARD TO THE CAUSE OR CAUSES RELATED THERETO,
INCLUDING THE NEGLIGENCE OF ANY PARTY, WHETHER SUCH NEGLIGENCE BE SOLE, JOINT OR CONCURRENT, OR ACTIVE OR PASSIVE. TO THE EXTENT ANY DAMAGES REQUIRED TO BE PAID HEREUNDER ARE LIQUIDATED, THE PARTIES
ACKNOWLEDGE THAT THE DAMAGES ARE DIFFICULT OR IMPOSSIBLE TO DETERMINE, OR OTHERWISE OBTAINING AN ADEQUATE REMEDY IS INCONVENIENT AND THE DAMAGES CALCULATED HEREUNDER CONSTITUTE A REASONABLE
APPROXIMATION OF THE HARM OR LOSS. 

SECTION 14.    MISCELLANEOUS    

14.1.  This
Contract shall be binding upon and inure to the benefit of the successors, assigns, personal representatives, and heirs of the respective parties hereto, and the covenants,
conditions, rights and obligations of this Contract shall run for the full term of this Contract. No assignment of this Contract, in whole or in part, will be made without the prior written consent of
the non-assigning party (and shall not relieve the assigning party from liability hereunder), which consent will not be unreasonably withheld or delayed; provided, either party may
(i) transfer, sell, pledge, encumber, or assign this Contract or the accounts, revenues, or proceeds hereof in connection with any financing or other financial arrangements, or
(ii) transfer its interest to any parent or affiliate by assignment, merger or otherwise without the prior approval of the other party. Upon any such assignment, transfer and assumption, the
transferor shall remain principally liable for and shall not be relieved of or discharged from any obligations hereunder. 

14.2.  If
any provision in this Contract is determined to be invalid, void or unenforceable by any court having jurisdiction, such determination shall not invalidate, void, or make
unenforceable any other provision, agreement or covenant of this Contract. 

14.3.  No
waiver of any breach of this Contract shall be held to be a waiver of any other or subsequent breach. 

14.4.  This
Contract sets forth all understandings between the parties respecting each transaction subject hereto, and any prior contracts, understandings and representations, whether oral
or written, relating to such transactions are merged into and superseded by this Contract and any effective transaction(s). This Contract may be amended only by a writing executed by both parties. 

14.5.  The
interpretation and performance of this Contract shall be governed by the laws of the jurisdiction as indicated on the Base Contract, excluding, however, any conflict of laws
rule which would apply the law of another jurisdiction. 

11

 

14.6.  This
Contract and all provisions herein will be subject to all applicable and valid statutes, rules, orders and regulations of any governmental authority having jurisdiction over
the parties, their facilities, or Gas supply, this Contract or transaction or any provisions thereof.

is no third party beneficiary to this Contract. 

14.8.  Each
party to this Contract represents and warrants that it has full and complete authority to enter into and perform this Contract. Each person who executes this Contract on behalf

headings and subheadings contained in this Contract are used solely for convenience and do not constitute a part of this Contract between the parties and shall not be used to
construe or interpret the provisions of this Contract. 

14.10.  Unless
the parties have elected on the Base Contract not to make this Section 14.10 applicable to this Contract, neither party shall disclose directly or indirectly without
the prior written consent of the other party the terms of any transaction to a third party (other than the employees, lenders, royalty owners, counsel, accountants and other agents of the party, or
prospective purchasers of all or substantially all of a party's assets or of any rights under this Contract, provided such persons shall have agreed to keep such terms confidential) except
(i) in order to comply with any applicable law, order, regulation, or exchange rule, (ii) to the extent necessary for the enforcement of this Contract, (iii) to the extent
necessary to implement any transaction, or (iv) to the extent such information is delivered to such third party for the sole purpose of calculating a published index. Each party shall notify
the other party of any proceeding of which it is aware which may result in disclosure of the terms of any transaction (other than as permitted hereunder) and use reasonable efforts to prevent or limit
the disclosure. The existence of this Contract is not subject to this confidentiality obligation. Subject to Section 13, the parties shall be entitled to all remedies available at law or in
equity to enforce, or seek relief in connection with this confidentiality obligation. The terms of any transaction hereunder shall be kept confidential by the parties hereto for one year from the
expiration of the transaction. 

In
the event that disclosure is required by a governmental body or applicable law, the party subject to such requirement may disclose the material terms of this Contract to the extent so required, but
shall promptly notify the other party, prior to disclosure, and shall cooperate (consistent with the disclosing party's legal obligations) with the other party's efforts to obtain protective orders or
similar restraints with respect to such disclosure at the expense of the other party. 

14.11  The
parties may agree to dispute resolution procedures in Special Provisions attached to the Base Contract or in a Transaction Confirmation executed in writing by both parties. 

DISCLAIMER: The purposes of this Contract are to facilitate trade, avoid misunderstandings and make more definite the terms of contracts of purchase and

TO NAESB'S DISCLAIMER OF, ANY AND ALL WARRANTIES, CONDITIONS OR REPRESENTATIONS, EXPRESS OR IMPLIED, ORAL OR WRITTEN, WITH RESPECT TO THIS CONTRACT OR ANY PART THEREOF, INCLUDNG ANY AND ALL IMPLIED
WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY, OR FITNESS OR SUITABILITY FOR ANY PARTICULAR PURPOSE (WHETHER OR NOT NAESB KNOWS, HAS REASON TO KNOW, HAS BEEN
ADVISED, OR IS OTHERWISE IN FACT AWARE OF ANY SUCH PURPOSE), WHETHER ALLEGED TO ARISE BY LAW, BY REASON OF CUSTOM OR USAGE IN THE TRADE, OR BY COURSE OF DEALING. EACH USER OF THIS CONTRACT ALSO AGREES
THAT UNDER NO CIRCUMSTANCES WILL NAESB BE LIABLE FOR ANY DIRECT, SPECIAL, INCIDENTAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES ARISING OUT OF ANY USE OF THIS CONTRACT.

  SPECIAL PROVISIONS TO BASE CONTRACT FOR
  SALE AND PURCHASE OF NATURAL GAS (FORM NAESB Standard 6.3.1)
  BY AND BETWEEN SHELL ENERGY NORTH AMERICA (US), L.P. AND DALLAS CLEAN ENERGY, LLC
  DATED MARCH
30, 2009    
    

 SECTION  

			
	1.2	 	Oral Transaction Procedure:
	

 	
 	
Delete the fifth sentence, and replace with the following: "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 the Section 1.2 (Oral Transaction Procedure); provided, however, the parties agree that
with respect to any transaction having a Delivery Period of less than one Month that such transactions shall be documented by a recording of the telephone transaction, which recording may be made by either or both parties, and that neither party
shall submit a written Transaction Confirmation. If any transaction having a Delivery Period of less than one Month is not recorded by the Confirming Party, then the Confirming Party shall, and the other party may, confirm such transaction by sending
a Transaction Confirmation by facsimile, EDI or mutually agreeable electronic means. The failure to send a Transaction Confirmation shall not invalidate the oral agreement of the parties."
	
1.4	
 	
At the end of Section 1.4, insert the following text: "For those transactions documented by telephone recordings, no such transaction shall be vitiated should a malfunction occur in equipment regularly utilized
for recording transactions or retaining any recorded transactions or the operation thereof, and in such event the transaction shall be evidenced by the written and computer records of the parties concerning the transaction made contemporaneously with
the telephone conversation."
	
2.27	
 	
At the end of the sentence add the phrase: "except for those transactions having a Delivery Period of less than one Month which are documented by telephone recordings pursuant to Section 1.2."
	
5	
 	
Add the following sentence at the end of the paragraph: "EXCEPT FOR THE OTHER PROVISIONS IN THIS SECTION 5, SELLER HEREBY NEGATES ALL EXPRESS, IMPLIED, OR STATUTORY REPRESENTATIONS AND WARRANTIES OF ANY KIND,
INCLUDING THOSE RELATING TO MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR ARISING FROM COURSE OF DEALING OR USAGE OF TRADE."
	
10.1	
 	
At the end of Section 10.1, insert the following sentence: "In the event that Shell Energy North America (US), L.P. maintains either an S&P issuer rating of BBB- or a Moody's corporate issuer rating of
Baa3, or higher, then Shell Energy North America (US), L.P. shall not be required to provide any Adequate Assurance of Performance."
	
10.3.1	
 	
Add the following sentence to the end of the first paragraph of Section 10.3.1: "If the determination pursuant to clauses (x) and (y) above of the difference between the Market Value(s) and Contract
Value(s) of all the Terminated Transactions does not result in an amount being owed to the Non-Defaulting Party, it shall be deemed that such difference is zero."
	
11.2	
 	
Insert the phrase "and (vi) a claim of Force Majeure of the foregoing type by a third party supplying the Gas delivered or to be delivered hereunder" before the period and after the word "jurisdiction" in the
seventh line of Section 11.2.
