CONSTRUCTION & OPERATING AGREEMENT 
  
 THIS PIPELINE
CONSTRUCTION & OPERATING AGREEMENT (this “Agreement”) is made and entered into on this 30 day of November, 2005, by and between ATMOS PIPELINE - TEXAS, a Division of Atmos Energy Corporation, a Texas and Virginia corporation
(“Atmos”) and ENERGY TRANSFER FUEL, LP, a Delaware limited partnership (“ETF”). Atmos and ETF may sometimes be referred to collectively as “Parties” or individually as a “Party.” 
  
 PURPOSE 
  
 The Parties have agreed to construct a natural gas pipeline to serve gas distribution customers in developing areas of North
Texas and to provide gas producers and other shippers in the Fort Worth Basin area of Texas with pipeline capacity to reach markets on both the Atmos and ETF pipeline systems. The Parties have agreed to construct a pipeline and to contribute
portions of the capacity on each Party’s respective existing pipeline systems in order to achieve that purpose. 
  
 RECITALS 
  
 1. The Parties have agreed to construct, operate and own a 30-inch pipeline approximately 45 miles in length, running from an interconnection with Atmos’ Line W near Justin in Denton County, Texas to a point at or near the ETF Collin
Line and the Atmos D17-9 pipeline, both of which are in Collin County, Texas (together with all appurtenances, real property interests and associated compression at or near Justin, Texas and Howard, Texas, the “NSL Pipeline”). 

 
 2. Each Party will own a 50% undivided interest in the NSL Pipeline.

  
 3. This Agreement sets forth the terms and conditions
governing the rights and relationship of the Parties in and to the NSL Pipeline. 
  
 4. Capitalized terms used in this Agreement, when not defined in context, are defined in the Accounting Procedures or other Schedules and Exhibits to this Agreement. The Schedule of Definitions attached hereto lists
terms defined in this Agreement and the Section number where the definition may be found.

	 	1.	the rights to utilize certain pipeline line rights-of-way that are owned by it, and that are described on the exhibit to Exhibit F hereto, to facilitate Construction;


  

	 	2.	all engineering and other work completed to date concerning pipeline routing and design; 

  

	 	3.	any work performed by Atmos pursuant to Section 4.8; and 

  

	 	4.	the cost of outside legal counsel reasonably acceptable to both Parties, in connection with the review and negotiation of easements and rights-of-way by ETF under
Section 4.2(a)(iv) and 4.2(b), below, with the exception of costs under Section 4.2(a)(iv)4 (which costs shall remain the responsibility of ETF). 

  

	 	(ii)	provide an amount of money that is equal to: 

  

	 	1.	50% of that portion of the Construction Costs described in Section 4.5(a), for Construction of the pipeline portion of the NSL Pipeline. This portion of Atmos’
contribution is limited to a total of $42,500,000.00; and 

  

	 	2.	50% of that portion of the Construction Costs described in Section 4.5(b), for constructing compression, without regard to the limit set forth in sub-paragraph 2.1(a)(ii)1
above. 

  
 (b) The Management Committee will, no
later than January 10, 2006, determine: 
  

	 	(i)	the portion of the NSL Pipeline that was in service and capable of flowing gas as of December 31, 2005, based upon any Segment Certificate of Completion issued pursuant to
Section 4.11(d) or by issuing a Segment Certificate of Completion effective as of December 31, 2005; and 

  

 Pipeline Construction and 
 Operating Agreement - Page 5 









	 	(ii)	the portion of the Construction Costs attributable to any such Segment (the “Segment Cost”). 

  
 (c) In order to make the contribution set forth in paragraph (a)(ii), above, Atmos will pay: 
  

	 	(i)	50% of Atmos’ share of the Segment Cost. This payment will be made no later than 10 days following Atmos’ receipt of ETF’s invoice setting forth the Segment Cost as
determined by the Management Committee; and 

  

	 	(ii)	subject to being “trued-up” pursuant to Section 2.4(a), 50% of the balance of Atmos’ portion of the Construction Costs, no later than 10 days following the
Operational Date. 

  

	2.2	ETF Contributions. As its contribution under this Agreement, ETF will provide an amount of money that is equal to the difference between: 

  
 (a) the Construction Costs (as defined in Section 4.5(c)); and

 (c) Upon such “true-up,” 50% of the agreed-upon value will be credited toward payment of Atmos’ share of the Construction Costs as
determined pursuant to paragraph (b) of this Section 2.4. For example, if the Management Committee determines that the value of 100% of such contribution is $5,000,000 and the Management Committee determines, pursuant to the audit
performed under the terms of paragraph (a), that Atmos owes ETF $10,000,000, Atmos will only be required to pay ETF $7,500,000 ($10,000,000, less 50% of $5,000,000 or $2,500,000 equals $7,500,000). 
  
 (d) No later than 10 days following the release of the results of the audit
performed pursuant to paragraph (b) of this Section 2.4, the Party owing the greater amount, according to the results of the audit, will pay the other Party the net amount.

 (b) From the date the Constructor or Operator notifies the Management
Committee in writing of its intention to do either of items (i) or (ii), above, the Management Committee will have 120 days in which to select a successor Constructor or Operator. The current Constructor, or Operator, as applicable, will
continue to serve in that capacity until the Management Committee has selected a successor. 
  
 (c) The Constructor’s or Operator’s withdrawal under this Section 3.3 does not affect a Party’s, or its permitted assignee’s, right to vote as a Member of the Management Committee. 

 

	3.4	Removal of the Constructor or Operator. 

  
 (a) The Constructor or Operator will be discharged and its powers, rights, and duties terminated if the Constructor or Operator: 
  

	 	(i)	becomes insolvent as defined in §101.32 of the U.S. Bankruptcy Code.;

simultaneously with each announced change in the Bank Prime Loan Rate. 
  
 (c) Interest will be compounded daily and computed for the actual number of days elapsed on the basis of a year consisting of 365, or, when appropriate, 366 days. 
  
 (d) In no event may the interest rate provided for in this Agreement ever exceed the maximum lawful interest rate allowed by
the laws of the State of Texas and if at any time or under any circumstances the interest rate calculated herein exceeds the maximum rate allowed by law, the amount due will be limited to the maximum lawful interest rate. 
  

	6.5	Other Effects of Late Payment. Without limiting the other remedies available to the Operator, if a Party is more than 30 days late in making any payment due under the terms
of this Agreement, the Operator may file the Recording Memorandum, attached hereto as Exhibit H, or any other documents it deems necessary as a lien or mortgage in the applicable real estate records or a financing statement with the proper
officer under the Uniform Commercial Code (the “Code”), or both, and will be entitled to exercise the rights and remedies of a secured party under the Code. The Party filing the lien or mortgage must promptly place of record a release of
the lien or mortgage if the owing Party makes payment in full of the amounts due. 

  

	6.6	Payment Disputes.

 (b) Upon the termination of this Agreement, all rights and obligations hereunder will cease, other than: 
  

	 	(i)	rights and obligations which accrued prior to termination; 

  

	 	(ii)	the rights of each Party to its own undivided interest in the NSL Pipeline; and 

  

	 	(iii)	any other rights expressly provided in this Agreement to be rights surviving termination of this Agreement. 

  
 9.2 Liquidation Upon Termination. 
  
 (a) If at the end of the Term, as set forth in Section 9.1(a), a Party
(the “Selling Party”) wishes to dispose of its interest, other than as permitted by Section 9.4(a), it must give written notice of its desire to the other Party and will have the obligation, upon request of the other Party (the
“Continuing Party”) to negotiate in good faith regarding a sale of its interest to the Continuing Party. 
  
 (b) If the negotiation is unsuccessful, then the Selling Party may liquidate its interest, or any part thereof, by sale to the highest and best bidder,
intact, in parts or as salvage. If the Selling Party elects to sell under the terms of this paragraph (b) of this Section 9.2, then the Selling Party must: 
  

	 	(i)	notify the Continuing Party in writing of its intent to sell in this manner. The notice must set forth the estimated amount for which the Selling Party’s interest may be sold
and the manner in which Seller intends to sell; 

  

	 	(ii)	allow the Continuing Party a period of 60 days from the date of the notice in which to agree to match the amount or amounts set forth in the notice and to agree to acquire the
Selling Party’s interest, or the part or parts thereof offered for sale, for its own separate ownership and account. The Continuing Party must purchase all of the interest offered for sale; 

  

	 	(iii)	notify each prospective bidder that the Continuing Party has a prior right of first refusal. 

  

 Pipeline Construction and 
 Operating Agreement - Page 29 








 (c) If the Continuing Party does not elect, within the 60 day right of first refusal period, to purchase
the Selling Party’s interest as offered in sub-paragraph (b)(ii) of this Section 9.2, then the Selling Party may sell its interest or any part thereof to the highest bidder. 
  

	9.3	Dispute Resolution. Any dispute under this Article IX will be handled under the dispute resolution procedures of Article XII. 

  

	9.4	Restrictions on Transfer of Party Interests. 

  
 (a) No Party may transfer its interest in the NSL Pipeline, except as set forth in this Section 9.4. Any purported transfer not in compliance with
the provisions of this Section 9.4 and other applicable provisions of this Agreement contravenes this Agreement and is ineffective. For purposes of this Section 9.4, the word “transfer” and its derivatives includes all forms of
direct or indirect transfer or disposition, voluntary or involuntary, by merger or operation of law or otherwise, as well as the creation of any lien or encumbrance on all or any part of the NSL Pipeline or either Party’s interest therein.

  
 (b) Each Party may, from time to time, transfer all, but not
less than all, of its interest in the NSL Pipeline to a person or entity controlling, controlled by or under common control with, such Party (and for this purpose control means the direct or indirect beneficial and record ownership of all of the
economic and voting interests in the assignee)(an “Affiliate”) and the assignee will succeed to all of the assignor’s rights and obligations hereunder, but only if at the time of such transfer: 
  

	 	(i)	the assignee or transferee agrees in a writing delivered to the other Party that it will be bound in all respects by this Agreement; and 

  

	 	(ii)	the assignor or transferor is not relieved of its obligations under this Agreement unless: 

  

	 	1.	the assignee or transferee agrees, in a writing delivered to the other Party, to fully assume the performance of all such obligations; and 

  

	 	2.	the other Party agrees in writing to such assumption of performance by the assignee or transferee. 

  
 (c) Either Party may, without the consent of the other Party, transfer all, but not less than all, of its interest in the
NSL Pipeline to a party not the Affiliate of the Party, and the transferee will succeed to all of the transferor’s rights and obligations hereunder: 
  

	 	(i)	if the transferee agrees in a writing delivered to the other Party that it will be bound in all respects by this Agreement; and 

  

	 	(ii)	then only if such transfer is: 

  

	 	1.	as a result of a merger, corporate reorganization, consolidation or conversion; or 

  

 Pipeline Construction and 
 Operating Agreement - Page 30 









	 	2.	in connection with the sale of substantially all of a Party’s gas transmission assets located in the State of Texas. 

  
 In either case, the transferor is not relieved of its obligations under this Agreement
unless: 
  

	 	3.	the assignee or transferee agrees, in a writing delivered to the other Party, to fully assume the performance of all such obligations; and 

  

	 	4.	the other Party agrees in writing to such assumption of performance by the assignee or transferee.

the amount of $50,000.00. 

  
 (d) To the extent
necessary to permit either Party to enforce any provision of this Article X, the other Party agrees that, with respect to any Claims within the scope of this Article X, it will and does hereby waive any defense it may have by virtue of the
workers’ compensation laws of any state. 
  
 (e) Neither
Party shall have any obligations, pursuant to this Article X, to the extent that any portions of any Claims are collectible or otherwise recoverable: 
  

	 	(i)	under insurance maintained by Atmos, covering or otherwise pertaining to Claims resulting from the personal injury, including death resulting therefrom, to any employee, agent, or
representative of Atmos or ETF, in connection with the operation of the NSL Pipeline;

of the NSL Pipeline, neither Party shall be liable to the other Party, in connection with operations conducted by the Constructor or the Operator hereunder, for any loss or damage to, or destruction of: 
  

	 	(i)	the NSL Pipeline; or 

  

	 	(ii)	any property of the other Party. 

  
 (b) Section 10.2(a) notwithstanding, in the event that, in connection with operations conducted by the Constructor or the Operator hereunder, loss,
damage, or destruction occurs to either: 
  

	 	(i)	the NSL Pipeline, or 

  

 Pipeline Construction and 
 Operating Agreement - Page 32 









	 	(ii)	any property of either Party; then: 

  

	 	1.	Atmos will be responsible for and bear the cost of such loss, damage, or destruction to the extent of the Atmos Interest; and 

  

	 	2.	ETF will be responsible for and bear the cost of such loss, damage, or destruction to the extent of the ETF Interest; 

  
 provided, however, that to the extent that any such loss, damage, or
destruction results from any act or omission constituting the willful misconduct of either Party (including, without limitation, the willful misconduct of that Party’s employees, agents, or representatives), that Party shall be liable for, and
shall promptly reimburse the other Party for, the cost of such loss, damage, or destruction. 
  

	10.3	Liability for Damages. NOTWITHSTANDING ANY OTHER PROVISION HEREIN, IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER PARTY FOR ANY LOSS OF PROFITS, INCIDENTAL,

 ARTICLE XI 
 RELATIONSHIP OF PARTIES 
  

	11.1	No Partnership. Nothing in this Agreement shall be construed to create a relationship between the Parties, their agents, representatives, employees, consultants or
subcontractors of: (i) employer and employee; (ii) general or limited partnership (other than for federal or state income tax purposes); or (iii) fiduciary. This Agreement does not authorize any Party to act as general agent for the
other Party. Except as expressly provided for in this Agreement, neither Party shall have the authority to bind or obligate the other in any manner. Each Party shall (i) maintain complete supervision and control over its agents, employees,
consultants and sub-contractors; and (ii) determine the manner in which it fulfills its obligations under this Agreement. Notwithstanding anything to the contrary contained herein, each Party will indemnify and hold the other Party harmless
from any loss, liability, damage or expense, including reasonable attorney’s fees and court costs arising out of any unauthorized actions by a Party or its agents or representatives. 

  

	11.2	 Tax Matters. It is not the purpose or intention of the Parties to create, and this Agreement shall never be construed as creating, a joint venture, mining
partnership or other relationship whereby any Party shall be held liable for the acts, either of omission or commission, of any other Party hereto. If, however, for federal income tax purposes, this Agreement and the relationship established hereby
should be regarded as a partnership, then each of the Parties elects to be excluded from the application of all of the provisions of Subchapter K, Chapter 1, Subtitle A, of the Internal Revenue Code of 1986, as permitted and authorized by
Section 761 of said Code and the regulations promulgated 



  

 Pipeline Construction and 
 Operating Agreement - Page 33 









	 	 
thereunder. Should there be any requirement that each Party further evidence this election, each Party agrees to execute such documents and furnish such
other evidence as may be required by the Federal Internal Revenue Service. Each Party further agrees not to give any notices or take any other action inconsistent with the elections made hereby. If any future income tax law of the United States or
of any applicable state contains provisions permitting making of an election of the type permitted under the existing provisions of said laws referred to above, each of the Parties hereby makes such election or agrees to make such election as may be
permitted by such laws. In making these elections, each of the Parties states that the income derived by it from the operations under this Agreement or any other agreement executed pursuant hereto can be adequately determined without computation of
partnership taxable income. 


  

	11.3	Waiver of Partition. The ownership of the NSL Pipeline will at all times be maintained in the proportions set forth in this Agreement so that the NSL Pipeline may be operated
as a unit. During the term of this Agreement, the Parties each waive any right of partition (including any right to have any interest sold for the purposes of dividing the proceeds of such sale) of the NSL Pipeline or any part thereof or any real
and/or personal property owned by the Parties hereto as tenants-in-common pursuant to this Agreement, notwithstanding the grant of such right by any applicable law, and each Party hereto does hereby covenant that during the term of this Agreement it
will not at any time resort to any action at law or in equity to so partition. 

  
 ARTICLE XII 
 DISPUTE RESOLUTION 
  

	12.1	Disputes. Any dispute under this Agreement not resolved by the Management Committee must be submitted to the dispute resolution procedures of this Article XII. Any dispute
may be submitted to these procedures upon the written request of the Party seeking resolution.

of natural gas (individually, a “Layman,” collectively, the “Laymen”). The third member must be an attorney whose practice deals with pipeline issues (whether from a regulatory, operational or business perspective). Each Party
will choose one Layman, and the Laymen will choose the attorney member of the panel. 

  

	12.3	Submission to Arbitration. 

  
 (a) Either Party may request arbitration by submitting a written request to the other Party. The written request for arbitration must include the
requesting Party’s choice of a Layman to serve as arbitrator. 
  
 (b) The Party receiving the notice must respond to the requesting Party within 15 days of the receipt of the notice. The response must include its own choice of a Layman to serve as arbitrator. 
  

 Pipeline Construction and 
 Operating Agreement - Page 34 








 (c) The two Laymen must meet within 5 days of the date of the response letter to choose an attorney to
serve as the third arbitrator. The two Laymen must use reasonable efforts to choose a third arbitrator who will be impartial and independent of the Parties. The arbitration will commence as soon as possible after the third member of the arbitration
panel is selected. 
  
 (d) If the responding Party fails or
refuses to appoint an arbitrator, or the Laymen are unable to agree upon a third arbitrator, either Party may request the Chief U.S. District Court Judge for the Northern District of Texas or such other person designated by such judge to select an
arbitrator as soon as possible. 
  
 (e) Any arbitration hearing,
if one is desired by the arbitration panel, must be held at a place acceptable to the arbitration panel. The arbitration panel may elect to conduct the proceeding by written submissions from the Parties with exhibits, including interrogatories,
supplemented with appearances by the Parties as the arbitration panel may desire. The arbitration proceeding, subject only to the terms hereof, should be conducted informally and expeditiously and in such a manner as to result in a good faith
resolution as soon as reasonably possible under the circumstances. 
  
 (f) The award, and any other decision by the arbitration panel, must be by majority vote of the arbitrators. The decision of the arbitration panel with respect to any disputed matters submitted to the arbitration panel will be reduced to
writing, signed by each arbitrator and binding on the parties. Judgment upon the award(s) rendered by the arbitration panel may be entered and execution had in any court of competent jurisdiction, or application may be made to such court for a
judicial acceptance of the award and an order of enforcement. 
  
 (g) Each Party will bear their own legal fees and other costs incurred in presenting their respective cases, and the fees and expenses of the arbitrator appointed by that Party. The charges and expenses of the third arbitrator will be
shared equally by the parties. 
  

	12.4	Procedure. 

  
 (a) In fulfilling its duties hereunder, the arbitration panel may consult with and engage disinterested third parties to advise the arbitration panel
including, without limitation, engineers, attorneys, accountants and consultants, and the fees and expenses of such third parties will be considered to be charges and expenses of the arbitration panel. 
  
 (b) The arbitration panel may not award punitive, consequential, special or
incidental damages. 
  

	12.5	Replacement Arbitrator. Any replacement arbitrator, should one become necessary, will be selected in the same manner as the original arbitrators were selected.


  

	12.6	Exclusivity. No lawsuit based on a dispute under this Agreement may be instituted by either Party, other than to compel arbitration proceedings or enforce the award of the
arbitration panel. 

  

 Pipeline Construction and 
 Operating Agreement - Page 35 









	12.7	Privileges. All privileges under Texas and federal law, including attorney-client and work-product privileges, will be preserved and protected to the same extent that such
privileges would be protected in a federal or state court proceeding applying Texas or federal law, as the case may be.

reorganization, moratorium or similar laws affecting creditors’ rights generally and subject, as to enforceability, to equitable principles of general application regardless of whether enforcement is sought in a proceeding in equity or at law);

  
 (d) there is not pending or, to its knowledge, threatened
legal proceedings that could materially adversely affect its ability to perform its obligations under this Agreement; 
  
 (e) no Default Event with respect to it has occurred and is continuing and no such event or circumstance would occur as a result of its entering into or

 (g) it has entered into this Agreement in connection with the conduct of its business. 
  

	13.2	No Liens. 

  
 (a) Other than any lien created under Section 6.5, unless the Management Committee approves, neither the Operator nor Constructor may allow the NSL
Pipeline to be 

  

 Pipeline Construction and 
 Operating Agreement - Page 36 








 
encumbered by any lien without the prior written consent of the other Party, not to be unreasonably withheld. A reasonable condition of the other
Party’s consent will be the protection of the lien created under Section 6.5. 
  
 (b) Each Party agrees that the Operator or the other Party, at their option, may pay and discharge any tax, mortgage, or other lien upon the other Party’s interest in the NSL Pipeline, except for charges and
assessments properly and timely contested in good faith by any Party, and if the Operator or the other Party does so then the Operator or Party discharging the lien shall be subrogated to the lien, with the right to enforce the lien in any manner
provided by law. 
  

	13.3	Interpretation. 

  
 (a) When reference is made in this Agreement to a Section, such reference shall be to a Section of this Agreement unless otherwise indicated. 

 
 (b) For purposes of this Agreement the words “include,”
“includes” and “including” shall be deemed to be followed by the words “without limitation.” 
  
 (c) This Agreement shall be construed without regard to any presumption or rule requiring construction or interpretation against the party drafting or
causing any instrument to be drafted. 
  
 (d) The headings of the
various subdivisions of this Agreement (including the Accounting Procedure) are for convenience of reference only and shall be afforded no significance in the interpretation or construction of this Agreement. 
  
 (e) This Agreement may not be altered, changed or amended, except by an
instrument in writing, executed by all of the Parties. 
  

	13.4	No FERC Jurisdiction. Each Party hereto acknowledges that the other Party is an intrastate pipeline not subject to the jurisdiction of the Federal Energy Regulatory
Commission (“FERC”) under the Natural Gas Act of 1938. Any and all movement of natural gas through the pipeline facilities of either Atmos or ETF shall be structured and accomplished in such manner as to preserve the existing intrastate
nature of such pipeline facilities and neither Party shall be required to use its pipeline facilities hereunder in any manner that would make such facilities subject to FERC jurisdiction under the Natural Gas Act of 1938. Notwithstanding the
foregoing, to the extent that both Parties have the ability to offer transportation services under §311(a)(2) of the Natural Gas Policy Act to qualified shippers for the movement of interstate gas, the Parties will agree to work together to
offer this service to such approved shippers. 

  

	13.5	Regulatory Compliance. This Agreement and all operations hereunder shall be subject to all valid and applicable orders, laws, rules and regulations of any state or federal
authority having jurisdiction, but nothing contained herein shall be construed as an admission of jurisdiction, or the applicability of any order, law, rule or regulation which does not in fact apply. 

  

 Pipeline Construction and 
 Operating Agreement - Page 37 









	13.6	Force Majeure. Performance under this Agreement, other than to make payments due, shall be excused in the event any Party or the Operator is rendered unable, wholly or in
part, by force majeure to carry out its obligations under this Agreement, and, in this regard, it is agreed that, on such Party or the Operator giving notice in reasonably full particulars of such force majeure, in writing or by electronic means, to
the other Parties and the Operator, within a reasonable time after the occurrence of the cause relied on, then the obligations of the Operator or the Party giving such notice, so far as they are affected by such force majeure, shall be suspended
during the continuance of any inability so caused, but for no longer period, and such cause shall, so far as possible, be remedied with all reasonable dispatch. The term “force majeure” as employed herein means: acts of God; strikes,
lockouts or other industrial disturbances; acts of the public enemy, terrorist acts, wars, blockades, insurrections, civil disturbances, riots; epidemics, landslides, lightning, earthquakes, fires, storms, floods, and washouts; arrests, orders,
directives, requisitions, and actions, orders, rules, regulations or restraints of any government and governmental agencies and instrumentalities, either federal or state, civil or military; application of governmental curtailment rules and
regulations; explosions, breakage, or accident to machinery or lines of pipe; breakdown or accident to electric transmission lines and freezing of lines of pipe; and, other causes, whether of the kind herein enumerated or otherwise, not reasonably
within the control of the Party claiming suspension. It is understood and agreed that the settlement of strikes or lockouts is entirely within the discretion of the Party having the difficulty, and that the above requirement that any force majeure
be remedied with all reasonable dispatch does not require the settlement of labor disputes, strikes or lockouts by acceding to the demands of an opposing Party when such course is inadvisable in the discretion of the Party having the difficulty.


  

	13.7	Notices. Any notice, request, consent, election, report, or other communication required to be given hereunder shall be sent in writing via United States Mail or by
electronic transmission addressed as follows:

	13.8	 Waiver of Defaults or Rights. No waiver of any Party hereto, or of the Operator, of any one or more defaults or right(s) under any provisions of this
Agreement will operate as a waiver of any future defaults or right(s), whether of a like or of a different character. A

Party may reassert any right not previously asserted by providing written notice to the other Party. In the event of any dispute under this Agreement, the
Parties and the Operator shall, notwithstanding the pendency of such dispute, diligently proceed with the performance of this Agreement without prejudice to the rights of any Party. 


  

	13.9	Choice of Law and Venue. THIS AGREEMENT IS GOVERNED BY AND WILL BE CONSTRUED IN ACCORDANCE WITH LAWS OF THE STATE OF TEXAS WITHOUT GIVING EFFECT TO ANY CHOICE OR CONFLICT OF
LAW PROVISION OR RULE (WHETHER OF THE STATE OF TEXAS OR ANY OTHER JURISDICTION) THAT WOULD CAUSE THE APPLICATION OF THE LAWS OF ANY JURISDICTION OTHER THAN THE STATE OF TEXAS. THE PARTIES AGREE THAT THE AGGREGATE VALUE OF THE CONSIDERATION GIVEN AND
RECEIVED UNDER THIS AGREEMENT IS GREATER THAN $1 MILLION AND, THEREFORE, THIS AGREEMENT CONSTITUTES A “MAJOR TRANSACTION” AS DEFINED BY SECTION 15.020 OF THE TEXAS CIVIL PRACTICE AND REMEDIES CODE. THE PARTIES ALSO AGREE, PURSUANT TO
SECTION 15.020, THAT ANY LAWSUIT INVOLVING THIS AGREEMENT BROUGHT BY EITHER PARTY WILL BE BROUGHT ONLY IN DALLAS COUNTY, TEXAS, WHETHER SUCH LAWSUIT BE BROUGHT IN FEDERAL OR STATE COURT. THE PARTIES MUTUALLY CONSENT TO THE JURISDICTION OF THE
FEDERAL AND STATE COURTS IN DALLAS COUNTY, TEXAS, AND AGREE THAT ANY ACTION, SUIT, OR PROCEEDING CONCERNING, RELATED TO, OR ARISING OUT OF THIS AGREEMENT AND THE NEGOTIATION OF THIS AGREEMENT WILL BE BROUGHT ONLY IN A FEDERAL OR STATE COURT IN
DALLAS COUNTY, TEXAS. THE PARTIES AGREE THAT THEY WILL NOT RAISE ANY DEFENSE OR OBJECTION OR FILE ANY MOTION BASED ON LACK OF PERSONAL JURISDICTION, IMPROPER VENUE, INCONVENIENCE OF THE FORUM, OR THE LIKE IN ANY CASE FILED IN A FEDERAL OR STATE
COURT IN DALLAS COUNTY, TEXAS. THIS AGREEMENT IS MADE AND PARTIALLY PERFORMABLE IN DALLAS COUNTY, TEXAS, AND VENUE SHALL BE IN DALLAS COUNTY, DALLAS, TEXAS. 

  

	13.10 	Entire Agreement. This Agreement and the attachments thereto constitute the entire agreement between the Parties with respect to the subject matter hereof, superseding any
and all prior agreements, written or oral, between the Parties. This Agreement may not be amended other than by written amendment signed by both Parties.

Measurement Law, Chapter 91, Subchapter C of the Texas Natural Resources Code, the atmospheric (barometric) pressure will be presumed, to be 14.4 psia (irrespective of variations in actual atmospheric pressure from time to time) for purposes of
meter calibration and Gas measurement. 
  
 3.5 Temperature
Measurement. The temperature of the Gas will be determined by the continuous use of a recording thermometer. The temperatures recorded each day, during periods of flow only, will be used in computing the Gas volume for that day. 
  
 3.6 Specific Gravity. The specific gravity of the Gas may be
determined by means of: 
  
 (A) a chromatograph,
in which case the specific gravity recorded each day, during periods of flow only, must be used in computing the Gas volume for that day; or 
  
 (B) a continuous sample taken at the delivery points and the redelivery points, in which case the specific gravity of the Gas must be
determined at intervals of not more than 1 month, by fractional analysis calculated on a real Gas basis in accordance with ANSI/ASTM D3588-79 as it is now and from time to time may be revised, amended or supplemented. Specific gravities so
determined will be used in calculating Gas deliveries hereunder for the month in which the test is made and all succeeding months until a new sample is taken. 
  

 Page 4 








 3.7 Gross Heating Value. The Gross Heating Value of the Gas will be determined: 
  
 (A) by means of a chromatograph or other recording device
generally acceptable in the industry, in which case the arithmetical average of the hourly Gross Heating Value recorded each day, during periods of flow only, will be considered as the Gross Heating Value of the Gas delivered or redelivered during
such day; or 
  
 (B) if a recording device is not
available, by the use of a continuous sample taken at the delivery points and redelivery points at 1 month intervals, in which case the Gross Heating Value will be obtained by chromatographic analysis in accordance with ANSI/ASTA D3588-79, on a real
Gas basis, using the value of the physical constants for the Gas compounds set forth therein. The Gross Heating Value of the Gas so determined will be used in calculating Gas deliveries for the month in which the sample is taken and all succeeding
months until such time as a new sample is taken. 
  
 3.8
Standards. All measurement volumes will be corrected for super-compressibility and deviation from the Ideal Gas Laws, as determined by use of tables or formulas published by the AGA (AGA 8 Detailed, AGA-Gross or NX-19), as amended, revised or
supplemented from time to time. 
  
 3.9 Inaccuracy or Failure
of Measurement Equipment. 
  
 (A) If any Gas
measurement equipment is found to be inaccurate by 1% or more when tested, the Operator must correct: 
  

	 	(1)	the registration of the equipment so that it measures accurately; and 

  

	 	(2)	any Gas accounting based upon the incorrect registration, at the rate of the inaccuracy: 

  

	 	(a)	for any period during which the inaccuracy is definitely known or agreed upon; or 

  

 Page 5 









	 	(b)	for any period not known or agreed upon, for a period extending back  1/2 of the time elapsed since the day of the last calibration. 

  
 (B) If any Gas measurement equipment is, for any reason, out of service or out of repair, so that the quantity of Gas deliveries or
redeliveries through such meter cannot be ascertained or computed by actual measurement, the quantity of Gas delivered during such period will be estimated upon the basis of the best available data, using the first of the following methods which is
feasible: 
  

	 	(1)	by using the registration of any check measuring equipment of any Party; 

  

	 	(2)	by correcting the error if the percentage of error is ascertainable by calibration, test or mathematical calculation; or 

  

	 	(3)	by estimating the quantity of deliveries or redeliveries during preceding periods under similar conditions when the meter was registering accurately.

TXOK) Point and the Hunt Point are referred to herein collectively as the “Secondary Delivery Points.” 
  
 (C) If all of the Equivalent Quantity cannot be delivered at the applicable Secondary Delivery Points, Atmos may nevertheless exercise the
Recall Rights with respect to the portion of the Equivalent Quantity that may be delivered at the Secondary Delivery Points, and the Parties will take all reasonable actions, including the use of other mutually agreeable points of delivery, to
permit the exercise of the Recall Rights with respect to the entire Equivalent Quantity. 
  
 (D) Notwithstanding Section 1.3(A)(1), above, Atmos and ETF may mutually agree from time to time to deliver and receive the Howard
Equivalent Quantity at other points that are not set forth herein. 
  
 1.4 Exchange Rights. 
  
 (A) ETF
will provide supplies of Gas at certain delivery points on the ETF pipeline system (as set forth below) to assist Atmos in providing services to its gas distribution customers (the “Exchange Rights”) by effecting the delivery of Gas to
Atmos at requested delivery points on the ETF system (each such requested transaction being an “Exchange”), so long as: 
  

	 	(1)	ETF has sufficient capacity available to make the Exchange without interrupting its customers; and 

  

	 	(2)	the Exchange does not negatively impact ETF economically or operationally. 

  

 3 of 6 








 (B) If Atmos intends to exercise the Exchange Rights, Atmos will endeavor to provide ETF
with at least 24 hours notice, but in any event, as much notice as is reasonably practicable under the circumstances, of its intent to exercise the Exchange Rights and an estimate of the quantity of Gas subject to the Exchange Rights. 
  
 (C) If Atmos requests an Exchange, and ETF, in its sole
reasonable opinion can accomplish the Exchange, under the standards set forth in paragraph (A), above, ETF will make Gas (the “Exchange Quantity”) available to Atmos at the following delivery points on the existing ETF pipeline system
(collectively, the “Exchange Delivery Point(s)”): 
  

	 	(1)	Springtown; 

  

	 	(2)	North Fort Worth; and 

  

	 	(3)	the Collin Point. 

  
 (D) ETF will also make Gas available to Atmos to assist Atmos in providing services to its distribution customers, to the extent that ETF
has Gas available, at: 
  

	 	(1)	when constructed, ETF’s North Main Point; and 

  

	 	(2)	when constructed, one or more delivery point(s) on the Bastrop Line. 

  
 (E) If Atmos receives an Exchange Quantity, Atmos will simultaneously provide an equivalent quantity of Gas at the Group A Points, the
Group B Points and the Bethel Point, in the same order of priority described in Section 1.3(a)(1) above.

 (A) The Parties agree that as of the date of this Agreement, neither Party is aware of any costs associated
with the exercise of the Recall Rights or the Exchange 

  

 4 of 6 








 
Rights nor do the Parties intend that the exercise of the Recall Rights or the Exchange Rights will cause either Party to interrupt customers.
Notwithstanding the foregoing, if ETF will incur, or at any time thereafter incurs, any Exchange Costs, ETF will so notify Atmos. Atmos will not be responsible for any Exchange Costs incurred prior to such notification by ETF, but will be
responsible for Exchange Costs after such notification if ETF is instructed to proceed with the Exchange or the exercise of the Recall Rights. The term “Exchange Costs” means: (i) a change in operating conditions that will result in
additional costs to ETF on its system or any affiliated systems; or (ii) charges from third parties as a result of the Exchange or the exercise of the Recall Rights. 
  
 (B) The Parties recognize that portions of the Gas hereunder may be transported or measured by third
parties, and therefore, the measurement of gas under this Agreement may involve the allocation of gas receipts or deliveries. The Parties will endeavor to work with such third parties in order to effectuate the delivery of the Gas hereunder. Each
Party will furnish or cause to be furnished to the other Party all data required to accurately account for all Gas received and delivered hereunder. 
  
 (C) Gas made available to ETF at the Secondary Delivery Point(s) must meet the quality specifications set forth in the Gas Quality,
Measurement and Testing Schedule attached to the Agreement. 
  
 (D) Atmos will reimburse ETF for any taxes ETF incurs that ETF would not otherwise have incurred, by reason of the exercise of the Recall Rights or the Exchange Rights.
