AGREEMENT, dated as of September 17, 2004 (this "Amendment"), in respect of (i)
the Uncommitted Amended and Restated Credit Agreement, dated as of July 1, 2002
(as amended, supplemented or otherwise modified prior to the date hereof, the
"Existing Credit Agreement"; as amended hereby and as further amended, restated,
supplemented or otherwise modified and in effect from time to time, the "Credit
Agreement") among ATMOS ENERGY MARKETING, LLC (formerly known as Woodward

the financial institutions from time to time parties thereto (the "Banks"),
FORTIS CAPITAL CORP., a Connecticut corporation ("Fortis"), as a Bank, an

         WHEREAS, the parties hereto desire to amend the Existing Credit
Agreement and the Support Agreement as more fully set forth herein;

         NOW, THEREFORE, in consideration of premises, and for other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties hereto hereby agree as follows:

         1. Defined Terms. Unless otherwise defined herein, terms defined in the
Existing Credit Agreement are used herein as therein defined.

         2. Amendments to Existing Credit Agreement. The Existing Credit
Agreement is hereby amended as follows:

         (a) Subsection (a) of the definition of "Eligible Accounts" set forth
in Section 1.01, Certain Defined Terms, is hereby deleted in its entirety and
the following new subsection (a) is inserted in lieu thereof:

                  "(a) Such Account (i) if for an amount in excess of
         $750,000.00, is acceptable to the Banks in their sole discretion and
         either (x) is the result of a sale to a Tier I or Tier II Account
         Party, or (y) is secured by letters of credit in form acceptable to the
         Banks in their sole discretion and issued by banks approved by the
         Banks in their sole discretion, or (ii) if for an amount of $750,000.00
         or less, such Account will be included as a Tier II Account unless




         such Account has been previously approved by the Banks as a Tier I
         Account;"

         (b) Subsection (i) of the definition of "Eligible Accounts" set forth
in Section 1.01, Certain Defined Terms, is hereby deleted in its entirety and
the following new subsection (i) is inserted in lieu thereof:

                  "(i) No Account Debtor in respect of such Account is (i)
         incorporated in or primarily conducting business in any jurisdiction
         outside of the U.S., unless such Account Debtor and the Account is
         approved by the Banks and the Borrower is notified in writing by the
         Administrative Agent, or (ii) an Affiliate of the Borrower, other than
         Atmos Energy Corporation, provided, that as long as Atmos Energy
         Corporation maintains an S&P rating of BBB or a Moody's rating of Baa2
         or better, and such Accounts would otherwise qualify as Eligible
         Accounts, Accounts of Atmos Energy Corporation (and its Subsidiaries
         and Affiliates that have been approved by Agents as Tier I Account
         Parties) may be included as Tier I Accounts to the extent that such
         Accounts do not exceed 50% of Borrower's total Accounts, provided,
         further, should Atmos Energy Corporation not maintain such ratings, and
         such Accounts would otherwise qualify as Eligible Accounts, Accounts of
         Atmos Energy Corporation may be included, subject to the approval of
         the Banks, as Eligible Accounts as a Tier I Account or a Tier II
         Account."


         (c) The definition of "Swap Bank" in Section 1.01, Certain Defined
Terms, is hereby amended by deleting such definition in its entirety and
substituting in lieu thereof the following new definition:

                  "'Swap Bank' means BNP Paribas, Societe Generale, or Fortis,
         or any Affiliate of BNP Paribas, Societe Generale, or Fortis, or any
         other Bank approved by the Agents."

         3. Amendment to Support Agreement. The sixth paragraph of the Support
Agreement is hereby amended by deleting such paragraph in its entirety and
substituting in lieu thereof the following new paragraph:

                  "Further, within 30 days of the event that our long-term
         unsecured debt is rated BBB- or lower by Standard and Poor's and Baa3
         or lower by Moody's, we will cause you, for the benefit of the Banks
         (as defined in the Facility), to be named as an additional insured and
         loss payee under all applicable insurance policies by endorsement of
         such policies in a manner reasonably satisfactory to you."

         4. Representations. To induce the Administrative Agent and the Banks to
enter into this Amendment, the Borrower ratifies and confirms each
representation and warranty set forth in the Credit Agreement as if such
representations and warranties were made on even date herewith, and further
represents and warrants that


                                      -2-


(a) no material adverse change has occurred in the financial condition or
business prospects of the Borrower since the date of the last financial
statements delivered to the Administrative Agent and the Banks, (b) no Default
or Event of Default has occurred and is continuing, and (c) the Borrower is
fully authorized to enter into this Amendment. THE BORROWER ACKNOWLEDGES THAT
THE CREDIT AGREEMENT PROVIDES FOR A CREDIT FACILITY THAT IS COMPLETELY OPTIONAL
ON THE PART OF THE BANKS AND THAT THE BANKS HAVE ABSOLUTELY NO DUTY OR
OBLIGATION TO ADVANCE ANY REVOLVING LOAN OR TO ISSUE ANY LETTER OF CREDIT.
BORROWER REPRESENTS AND WARRANTS TO THE BANKS THAT BORROWER IS AWARE OF THE
RISKS ASSOCIATED WITH CONDUCTING BUSINESS UTILIZING AN UNCOMMITTED FACILITY.

         5. Conditions Precedent. This Amendment shall become effective on the
first date (the "Effective Date") on which each of the following conditions
precedent shall have been satisfied:


         (a) Fees and Expenses. Each of the Agents and the Banks parties to this

         reasonably request.

         (c) No Default. On the Effective Date, the Borrower shall be in
compliance in all material respects with all of the terms and provisions set

AGREEMENTS AMONG THE PARTIES.
