11. Indemnification and Contribution.

(a) Atmos Energy and the Issuer, jointly and severally, shall indemnify and hold harmless the Underwriter, its directors, officers, agents, affiliates and employees and each person, if any, who controls the Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of the Bonds), to which the Underwriter, director, officer, agent, affiliate, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in (A) the Registration Statement, the Preliminary Prospectus, the Pricing Package, the Intex File, the Prospectus or in any amendment or supplement thereto and (B) any Issuer Free Writing Prospectus or in any amendment or supplement thereto or (ii) the omission or alleged omission to state in the Registration Statement, the Preliminary Prospectus, the Pricing Package, the Intex File, the Prospectus or any Issuer Free Writing Prospectus or in any amendment or supplement thereto, any material fact required to be stated therein or necessary to make the statements therein not misleading, and shall reimburse the Underwriter and each such director, officer, employee, agent, affiliate or controlling person promptly upon demand for any legal or other expenses reasonably incurred by the Underwriter, director, officer, employee, agent, affiliate or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim,

- 25 -

damage, liability or action as such expenses are incurred; provided, however, that Atmos Energy and the Issuer shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Preliminary Prospectus, the Pricing Package, the Prospectus, any Issuer Free Writing Prospectus or in any such amendment or supplement thereto, in reliance upon and in conformity with the Underwriter Provided Information. The foregoing indemnity agreement is in addition to any liability which Atmos Energy and the Issuer may otherwise have to the Underwriter or to any director, officer, employee, agent, affiliate or controlling person of the Underwriter.

(b) The Underwriter shall indemnify and hold harmless Atmos Energy and the Issuer, and each of their respective directors, managers, officers, agents and employees, and each person, if any, who controls Atmos Energy or the Issuer within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage, liability or expense (including reasonable attorney’s fees and expenses relating to investigating or defending or preparing to defend), or any action in respect thereof, to which Atmos Energy or the Issuer, or any such director, manager, officer, employee, agent, affiliate or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Preliminary Prospectus, the Pricing Package, the Prospectus or any Issuer Free Writing Prospectus or in any amendment or supplement thereto, or (ii) the omission or alleged omission to state in the Registration Statement, the Preliminary Prospectus, the Pricing Package, the Prospectus or any Issuer Free Writing Prospectus or in any amendment or supplement thereto, any material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning the Underwriter furnished to Atmos Energy through the Underwriter by or on behalf of the Underwriter specifically for inclusion therein, which information is limited to the information set forth in Schedule IV of this Agreement (“Underwriter Provided Information”). The foregoing indemnity agreement is in addition to any liability that the Underwriter may otherwise have to the Atmos Energy, or any such director, officer, employee, agent, affiliate or controlling person.

(c) Promptly after receipt of notice by an indemnified party under this Section 11 of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 11, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 11 except to the extent it has been materially prejudiced by such failure and, provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 11. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 11 for any legal or other

- 26 -

expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the indemnified party shall have the right to employ such other counsel as the indemnified party may deem necessary, and the indemnifying party shall bear the reasonable legal or other expenses of such other counsel if (i) the indemnifying party shall have agreed; (ii) the indemnifying party has failed within a reasonable time to assume the defense of and retain counsel reasonably satisfactory to the indemnified party; or (iii) the named parties in any such proceeding (including any impleaded parties) include both the indemnified party and the indemnifying party, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them; provided, further, however, that the indemnifying party shall not, in connection with any one such claim or action or separate but substantially similar or related claims or actions in the same jurisdiction, arising out of the same general allegations or circumstances, be liable for the legal or other expenses of more than one separate firm of attorneys (in addition to one local counsel in each jurisdiction) for all of the indemnified parties, which firm shall be designated in writing by Atmos Energy or the Underwriter, as applicable, and that all such legal or other expenses shall be reimbursed as they are incurred. No indemnifying party shall (i) without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding, provided that such unconditional release may be subject to parallel release by a claimant or plaintiff of such indemnified party, and does not include any findings of fact or admissions of fault or culpability as to the indemnified party, or (ii) be liable for any settlement of any such action effected without its written consent, but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d) If the indemnification provided for in this Section 11 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 11(a) or 11(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by Atmos Energy, on the one hand, and the Underwriter, on the other, from the offering of the Bonds or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of Atmos Energy, on the one hand, and the Underwriter, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by Atmos Energy or the Issuer, on the one hand, and the Underwriter, on the other, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Bonds purchased under this Underwriting Agreement (before deducting expenses) received by Atmos Energy and the Issuer, as set forth in the table on the cover page of the Prospectus, on the one hand, and the total underwriting discounts and commissions received by the Underwriter with respect to the aggregate principal

- 27 -

amount of Bonds purchased under this Underwriting Agreement, as set forth in the table on the cover page of the Prospectus, on the other hand. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by Atmos Energy and the Issuer or the Underwriter, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. Atmos Energy, the Issuer and the Underwriter agree that it would not be just and equitable if contributions pursuant to this Section 11(d) were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 11(d) shall be deemed to include, for purposes of this Section 11(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action. Notwithstanding the provisions of this Section 11(d), the Underwriter shall not be required to contribute any amount in excess of the amount by which the total underwriting discount and commission received by the Underwriter with respect to the offering of the Bonds underwritten by it exceeds the amount of any damages that the Underwriter has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

12. Termination. This Underwriting Agreement may be terminated, at any time prior to the Closing Date with respect to the Bonds by the Underwriter by written notice to the Issuer if after the date hereof and at or prior to the Closing Date (a) there shall have occurred any general suspension of trading in securities on the New York Stock Exchange (“NYSE”) or there shall have been established by the NYSE, or by the Commission any general limitation on prices for such trading or any general restrictions on the distribution of securities, or a general banking moratorium declared by New York or federal authorities or (b) there shall have occurred any (i) material outbreak or escalation of hostilities (including, without limitation, an act of terrorism) or (ii) declaration by the United States of war or national or international calamity or crisis, including, but not limited to, a material escalation of hostilities or a calamity that existed prior to the date of this Underwriting Agreement or (iii) material adverse change in the financial markets in the United States, and the effect of any such event specified in clause (a) or (b) above on the financial markets of the United States shall be such as to materially and adversely affect, in the reasonable judgment of the Underwriter, their ability to proceed with the public offering or the delivery of the Bonds on the terms and in the manner contemplated by the Prospectus. Any termination hereof pursuant to this Section 12 shall be without liability of any party to any other party except as otherwise provided in Sections 8(a)(vi) and 11 hereof.

13. Representations, Warranties and Covenants of the Underwriter. The Underwriter represents, warrants and agrees with the Issuer and Atmos Energy that, unless the Underwriter obtained, or will obtain, the prior written consent of the Issuer or Atmos Energy, it (x) has not delivered, and will not deliver, any Rating Information (as defined below) to any Rating Agency until and unless the Issuer or Atmos Energy advises the Underwriter that such Rating Information is posted to password-protected website maintained by the Servicer pursuant to paragraph (a)(3)(iii)(B) of Rule 17g-5 under the Exchange Act in the same form as it will be provided to such Rating Agency, and (y) has not participated, and will not participate, with any Rating Agency in any oral communication of any Rating Information without the participation of a representative of the Issuer or Atmos Energy. For purposes of this Section 13, “Rating Information” means any information provided to a Rating Agency for the purpose of determining an initial credit rating on the Bonds.

- 28 -

14. Absence of Fiduciary Relationship. Each of the Issuer and Atmos Energy acknowledges and agrees that the Underwriter is acting solely in the capacity of an arm’s length contractual counterparty to the Issuer and Atmos Energy with respect to the offering of the Bonds contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Issuer or Atmos Energy. Additionally, the Underwriter is not advising the Issuer or Atmos Energy as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Issuer and Atmos Energy shall consult with their own advisors concerning such matters and shall be responsible for making their own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriter shall have no responsibility or liability to the Issuer or Atmos Energy with respect thereto. Any review by the Underwriter of the Issuer or Atmos Energy, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriter and shall not be on behalf of the Issuer or Atmos Energy.

15. Notices. All communications hereunder will be in writing and may be given by United States mail, courier service, telecopy, telefax or facsimile (confirmed by telephone or in writing in the case of notice by telecopy, telefax or facsimile) or any other customary means of communication, and any such communication shall be effective when delivered, or if mailed, three days after deposit in the United States mail with proper postage for ordinary mail prepaid, and if sent to the Underwriter, to it at the address specified in Schedule I hereto; and if sent to Atmos Energy, to it at 1800 Three Lincoln Centre, 5430 LBJ Freeway, Dallas, Texas 75240, Fax: (972) 855-3080, Attention: General Counsel; and if sent to the Issuer, to it at 1800 Three Lincoln Centre, 5430 LBJ Freeway, Dallas, Texas 75240, Attention: Manager. The parties hereto, by notice to the others, may designate additional or different addresses for subsequent communications.

16. Successors. This Underwriting Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and controlling persons referred to in Section 11 hereof, and no other person will have any right or obligation hereunder.

17. Applicable Law. This Underwriting Agreement will be governed by and construed in accordance with the laws of the State of New York.

18. Counterparts. This Underwriting Agreement may be signed in any number of counterparts, each of which shall be deemed an original, which taken together shall constitute one and the same instrument. The words “execution,” “signed,” “signature,” “delivery,” and words of like import in or relating to this Underwriting Agreement or any document to be signed in connection with this Underwriting Agreement shall be deemed to include electronic signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, and the parties hereto consent to conduct the transactions contemplated hereunder by electronic means.

- 29 -

19. Integration. This Underwriting Agreement supersedes all prior agreements and understandings (whether written or oral) among the Issuer, Atmos Energy and the Underwriter, or any of them, with respect to the subject matter hereof.

20. Recognition of the U.S. Special Resolution Regimes

(a) In the event that the Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from the Underwriter of this Underwriting Agreement, and any interest and obligation in or under this Underwriting Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Underwriting Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b) In the event that the Underwriter that is a Covered Entity or a BHC Act Affiliate of the Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Underwriting Agreement that may be exercised against the Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Underwriting Agreement were governed by the laws of the United States or a state of the United States.
