WHEREAS, the Settlement Agreement resolves all issues relating to the Atmos Energy Corp., Mid-Tex Division Statement of Intent filed with the ACSC Cities on September 24, 2007, in a manner that Atmos and ACSC ("the Signatories") believe is consistent with the public interest, and the 5ignatories represent diverse interests; WHEREAS, the Signatories believe that a fully contested hearing in the case would be time-consuming and entail substantial additional expense for all parties and that the public interest will be served by adoption of an ordinance consistent with the Settlement Agreement; NOW, THEREFORE, in consideration of the mutual agreements and covenants established herein, the Signatories, through their undersigned representatives, agree to and recommend for approval by the ACSC Cities the following Settlement Terms as a rneans of fully resolving ail issues raised in the September 20, 2007 Statement of Intent filed by Atmos on behalf of its Mid-Tex division: Settlement Terms N 1. Atmos and the ACSC Cities agree to the rates, terms and conditions reflected in the tariffs attached to this Settlement Agreement as Exhibit A. Said tariffs should allow Atmos an additional $10 million in annual revenue by implementation of rates shown in 1 SETTLEMENT AGREEMENT STATEMENT OF INTENT FILED BY ATMOS ENERGY, CORP., MID-TEX DIVISION ON SEPTEMBER 20, 2007 the proof of revenues attached as Exhibit B. Atmos and the ACSC Cities further agree that the rates, terms, and conditions reflected in Exhibit A to this Settlement Agreement comply with the rate-setting requirements of Chapter 104 of the Texas Utilities Code. ' The gas rates, terms and conditions established by this Settlement Agreement shall be effective for bills rendered on or after March 1, 2008. 2. The net plant amounts shown in the attached Exhibit B are reasonable for the plant that is used and useful in providing gas utility service. 3. Included as part of Exhibit A is a Rate Review Mechanism ("Rider RRM") that provides for an annual rate adjustment to reflect changes in billing determinants, operating and maintenance expense, depreciation expense, other taxes expense, and revenues as well as changes in capital investment and associated changes in gross revenue related taxes. Atmos agrees that effective with the implementation of the first RRM rate adjustment, Atmos shall file with the ACSC Cities a revised Rate R-Residential Sales Tariff to reduce the customer charge per bill from $10.69 per month to $7.OQ per month and to increase the volumetric portion of the rate (shown as $1.271 in Exhibit A) to the appropriate level to reflect reduction in customer charge from $10.69 to $7.00, as well as to reflect any change resulting from the RRM implementation. The first RRM rate adjustment is expected to occur October 1, 2008. Atmos and the ACSC Cities agree that following the initial RRM adjustment any subsequent implementation of RRM adjustments shall be supported as described in the Rider RRM, and sha11 limit changes to residential and commercial customer charge to no more than 20%. Further, the parties agree that any approved adjustment in excess of the 20% limitation on the residential and commercial customer chaxge shall be recovered through the volumetric portion of the rate. 4. With respect to the RRM, Atmos and the ACSC Cities agree that the rate increase limita.tions set forth in Rider RRM under Calculation of Rate Adjustment, subpart (c) sha11 not preclude Atmos from recovering any excluded costs during a subsequent Evalua.tion Period in which the 5% limitation for O&M expenses or net plant investment, respectively, is not reached or in a subsequent Statement of Intent case. To the extent that Atmos seeks to recover any excluded costs during a subsequent Evaluatian Period in which the 5% limitation for O&M expenses or net plant investment, respectively, is not reached or in a subsequent Statement of Intent case, Atmos shall identify these costs as a specific line item in the schedule accompanying the RRM rate adjustment filing. 5. With respect to the RRM, Atrnos further agrees to pay a11 reasonable and necessary expenses of each entity having original jurisdiction that are incurred to review the Company's annual RIZM filings. Atmos further agrees that in calculating the proposed rate for any Rate Effective Period, the Company shall not include: (1) any external legal, expert, or consultant costs to prepare and/or provide supportive information related to its filing; or (2) reimbursements to original jurisdiction entities, 6. Notwithstanding pazagraph 5 of this Settlement Agreement, Atmos and ACSC agree tha.t in the event of an appeal of an original jurisdiction entity's decision regarding a proposed RRM adjustment, recovery of rate case expenses shall be determined according to Chapters 103 and 104, T~x. U7T~,. CoDE Artr~r. Further, in the event of such appeal(s), 2 SETTLEMENT AGREEMENT STATEMENT OF INTENT FILED BY ATMOS ENERGY, CORP., MID-TEX DIVISION ON SEPTEMBER 20, 2007 Atmos shall recover any reimbursement made to the original jurisdiction entity through a surcharge to customer rates whether such reimbursements are made during the initial review period or appeal period. 7. Atmos agrees that it will make no filings on behalf of its Mid-Tex division under the provisions of T~x. U7'~L. CoDE At~7N. § 104.301 while the Rider RRM is in place, and any such filings pending at the time the RRM is approved will be trued-up for revenue and rate base components prior to implementation of the annual RRM. In the event that a regulatory authority fails to act or enters an adverse decision regarding the proposed annual RRM adjustment, the Railroad Commission of Texas shall, pursuant to the provisions of the Texas Utilities Code, have exclusive appellate jurisdiction to review the action or inaction of the regulatory authority exercising exclusive original jurisdiction over the RRM request. In addition, the Signatories agree that this Settlement Agreement shall not be construed as a waiver of the ACSC Cities' right to initiate a show cause proceeding or the Company's right to file a Statement of Intent under the provisions of the Texas Utilities Code. 8. Atmos and the ACSC Cities commit that during the Initial Implementation Period, as defined in the RRM tariff, Atmos and the ACSC Cities will not devote resources or efforts to advocate statutory changes involving rate stabilization mechanisms or the Gas Reliability Infrastructure Plan that is currently codified under TEx. UTIL. CODE § 104.301. 9. Atmos and the ACSC Cities agree that the gas cost portion of uncollectible expense sha11 be recovered through the Company's Rider GCR rather than through base rates. The change in accounting for the gas cost portion of uncollectible expense (including both the accrual of expense and write-off of accounts) shall become effective with the implementation of the first RRM rate adjustment. The first RRM rate adjustment is expected to occur October 1, 2008. In calculating the rate for the first Rate Effective Period, the Company shall utilize the same methodology as used in the Company's September 20, 2007 Statement of Intent with the only modification being to exclude the effects of the gas cost portion of uncollectible expense from the base rate calculation. 10. Atmos and the ACSC Cities further agree that expense associated with lost and unaccountable gas shall, based on an annual period, be recoverable through the Company's Rider GCR up to a ma~cimum of five {5) percent of the quantity of inetered gas, as provided under Commission Rule 7.5525, Lost and Unaccounted for Gas. Such change shall be effective with the complete 12 month reporting period ending June 30, 2008. 11. Included as part of Exhibit A to this Settlement Agreement is a new gas conservation program tariff (Rider CEE) that will be effective October 1, 2008. Atmos and the ACSC Cities agree that Atmos will fund $1 million of the allowable expenses incurred annually, with a customer rate component providing the remainder $1 million of funding. All customer-supplied funds will, prior to the commencement of the program, be used toward program implementation efforts and, upon implementation, be applied directly to the gas conservation materials and supplies. 3 SETTLEMENT AGREEMENT STATEMENT OF INTENT FILED BY ATMOS ENERGY, CORP., MID-TEX DNISION ON SEPTEMBER 20, 2007 12. Atmos and the ACSC Cities agree that the Company's requested revision of its weather normalization adjustment ("WNA") mechanism is appropriate, as modified by ACSC, and should be approved as set forth in Exhibit A to this Settlement Agreement, Specifically, the revision excludes non-weather sensitive commercial customers and modifies the WNA mechanism to calculate the VJNA adjustment based on weather stations at a regional level rather than under the current practice of associating all customers with a single weather location for purposes of determining the VJNA adjustment. 13. Atmos and the ACSC Cities agree that the three-year gas cost review process that is currently in effect for the Mid-Tex division should be eliminated. Atmos and the ACSC Cities further agree to collaborate to establish an alternate process wherein the prudence of gas costs recovered through the Rider GCR can be addressed. Until an agreed upon replacement mechanism has been established, the current gas cost review process shall remain in effect, unless changed by order of the Commission. 14. It is the intention of the Signatories that the ACSC Cities receive the benefit of any settlement agreement that Atmos enters into with other entities arising out of GUD No. 9672 (consolidated cases) or any associated appeals of GUD No. 9672. Therefore, Atmos agrees that if the rates, revenues, terms and conditions, or benefits accruing to the settling entity would be more beneficial to the ACSC Cities than the terms of this Settlement - Agreement, as determined by the ACSC Cities, such more favorable rates, revenues, terms and conditions, or benefits shall additionally accrue to the ACSC Cities. Similarly, if the Final Order in GUD No. 9672 or orders resulting from any associated appeals aze . determined by the ACSC Cities to result in rates, revenues, terms and conditions, or benefits that are more beneficial than the terms or this Settlement Agreement, such more favorable terms, revenues, terms and conditions shall additionally accrue to the ACSC Cities. However, the Signatories agree that the approval of the Rider RRM, the Rider WNA, the Rider CEE, and the Rider GCR, as shown in Exhibit A hereto, shall not be affected by the application of the "most favored nations" provisions contained in this paragraph, it being the understanding and the intent of the Signatories hereto that such taziffs shall continue in effectiveness according to their terms. The Signatories further , agree that the agreement reflected in paragraph 10 of this Settlement Agreement sha.ll not be affected by the application of the "most favored na.tions" provisions contained in this paragraph. 15.

With respect to the rate case expenses directly incurred by Atmos, the amount to be recovered through the surcharge to customers within the ACSC Cities shall be determined on a pro rata basis, consistent with the ACSC Cities' percentage of total Mid-Tex residential load (52%).

The total gas cost recovery amount due is determined by adding the gas cost calculated in Section (a) below and the pipeline cost calculated in Section (b) be{ow. The amount due for gas cost (Section (a)) is determined by multiplying the Gas Cost Recovery Factor (GCRF) by the Customer's monthly volume. For Customers receiving service under Rate R and Rate C, monthly volume will be calculated on an Mcf basis. For Customers receiving service under Rate I, monthly volume will be calcufated on an MMBtu basis and the quantities will be adjusted as necessary to recover actual costs. The amount due for pipeline cost (Section (b)) is determined by multiplying the Pipeline Cost Factor (PCF) by the Customer's monthly volume. For Customers receiving service under Rate R and Rate C, monthly volume will be calculated on an Mcf basis. For Customers receiving service under Rate I and ~ Rate T, mcrnthly volume will be°calculated on an M~IBtu basis and the quantities will be adjusted as necessary to recover actual costs. (a) Gas Cost Method of Calculation The monthly gas cost adjustment is calculated by the application of a Gas Cost Recovery Factor (GCRF), as determined with the following formula: GCRF = Estimated Gas Cost Factor (EGCF) + Reconciliation Factor (RF) + Taxes (TXS) + Adjustments (ADJ) EGCF = Estimated cost of gas, including lost and unaccounted for gas attributed to residential, commercial, and industrial sales, and any reconciliation balance of unrecovered gas costs, divided by the estimated total residential, commercial, and industriai sales. RF = Calculated by dividing the difference between the Actual Gas Cost lncurred, inclusive of interest, over the preceding twelve-month period ended June 30 and the Actual Gas Cost Bifled over that same twelve-month period by the estimated total residential, commercial, and industrial sales for the succeeding October through June billing months. Actual Gas Cost Tncurred = The sum of the costs booked in Atmos Energy Corp., Mid-Tex Division account numbers 80o through 8i3 and 858 of the NARUC Uniform System of Accounts, including the net impact of injecting and withdrawing gas from storage. Also includes a credit or debit for any out-of-period adjustments or unusual or nonrecurring costs typically considered gas costs and a credit for amounts received as Imbalance Fees or Curtailment Overpull Fees. Actual Gas Cost Billed = EGCF multiplied by the monthly volumes billed to Residential, Commercial and Industrial Sales customers, less the total amount of gas cost determined to have been uncollectible and written off which remain unpaid for each month of the reconciliation period. 17 EXHIBIT A TARIFF FOR GAS SERVICE ATMOS ENERGY CORP., MID-TEX DIVISION RIDER: Ridec GCR - Gas Cost Recovery I APPLICABLE TO: Entire System REVISION: DATE: EFFECTIVE DATE: PAGE: 2 OF 3 October 1, 2008 Any amount remaining in the reconciliation balance after the conclusion of the period of amortization will be maintained in the reconciliation balance and included in the collection of the next RF. Atmos Energy shall file annual reports with the Commission, providing by month the following amounts: Gas Cost Written Off. Margin Written Off, Tax and Other Written Off, Total Written Off, Gas Cost Collected and Margin Collected. TXS = Any statutorily imposed assessments or taxes applicabie to the purchase of gas divided by ~ the estimated total residential, commercial, and industrial sales. ADJ = Any surcharge or refund ordered by a regulatory authority, inclusive of interest, divided by the estimated total residential, commercial, and industrial sales. (b) Pipeline Cost Method of Calculation m Each month, a Pipeline Cost Factor (PCF) is cafculated separatefy for each Pipeline Cost Rate Class listed below. The formula for the PCF is: PCF = PP / S, where: PP =(P - A) x D, where: P= Estimated monthfy cost of pipeline service calculated pursuant to Rate CGS . D= Pipeline service allocation factor for the rate class as approved in the Company's most recent rate case, as follows: Pi eline Cost Rate Class Allocation Factor D Rate R - Residential Service .634783 Rate C - Commercial Service .302805 Rate I- Industrial Service and Rate T- Trans ortation Service .062412 A= Adjustment applied in the current month to correct for the difference between the actual and sstimated pipeline cost revenue of the second preceding month, calculated by the formula: A = R - (C = A2}, where: R= Actual revenue received from the appiication of the PP component in the second preceding month. C= Actual pipeline costs for the second preceding month. ~ A2 = The adjustment (A) applied to the PP component in the second preceding month.

The total gas cost recovery amount due is determined by adding the gas cost calcutated in Section (a) below and the pipeline cost calcutated in Section (b) below. The amount due for gas cost (Section (a)} is determined by multiplying the Gas Cost Recovery Factor (GCRF) by the Customer's monthly volume. For Customers receiving service under Rate R and Rate C, monthly volume wiN be calculated on an Mcf basis. For Customers receiving service under Rate I, monthly volume will be calculated on an MMBtu basis and the quantities will be a~justed as necessary to recover actual costs. The amount due for pipeline cost (Section (b}} is determined by multiptying the Pipeline Cost Factor (PCF) by the Customer's monthly volume. For Customers receiving service under Rate R and Rate C, monthly volume will be calculated on an Mcf basis. For Customers receiving service under Rate I and 4vi_ Ftate T, monthiy volume will be calculated on an MMBtu basis and the quantities will be adjusted as necessary to recover actual costs. (a) Gas Cost Method of Calculation The monthly gas cost adjustment is calculated by the application of a Gas Cost Recovery Factor (GCRF), as determined with the following formula: GCRF = Estimated Gas Cost Factor (EGCF) + Reconciliation Factor (RF) + Taxes (TXS) + Adjustments (ADJ) EGCF = Estimated cost of gas, including iost and unaccounted for gas attributed to residential, commercial, and industrial sales, and any reconciliation balance of unrecovered gas costs, divided by the estimated total residential, commercial, and industrial sales. RF = Calculated by dividing the difference between the Actual Gas Cost Incurred, inclusive of interest, over the preceding twelve-month period ended June 30 and the Actual Gas Cost Billed over that same twelve-month period by the estimated total residential, commerciai, and industrial sales for the succeeding October through June billing months. Actual Gas Cost Incurred = The sum of the costs booked in Atmos Energy Corp., Mid-Tex Division account numbers 80o through 8i3 and 8~8 of the NARUC Uniform System of Accounts, including the net impact of injecting and withdrawing gas from storage. Also includes a credit or debit for any out-of-period adjustrnents or unusual or nonrecurring costs typically considered gas costs and a credit for amounts received as Imbalance Fees or Curtailment Overpull Fees. Actual Gas Cost Billed = EGCF multiplied by the monthly volumes billed to Residential, Commercial and Industrial Sales customers, less the total amount of gas cost determined to have been uncollectible and written off which remain unpaid for each month of the reconcliation period.

Margin Written Off, Tax and Other Written Off, Total Written Off, Gas Cost Collected and Margin Collected. TXS = Any statutorily imposed assessments or taxes applicable to the purchase of gas divided by the estimated totat residential, commercial, and industrial sales. ADJ = Any surcharge or refund ordered by a regulatory authority, inclusive of interest, divided by the estimated total residential, commercial, and industrial sales. (b) Pipeline Cost Method of Ca(culation Each month, a Pipeline Cost Factor (PCF} is calculated separately for each Pipeline Cost Rate Class listed below. The formula for the PCF is: PCF = PP / S, where: PP =(P - A) x D, where: P= Estimated monthly cost of pipeline service calcuiated pursuant to Rate CGS D= Pipeline service allocation factor for the rate class as approved in the Company's most recent rate case, as follows: Pi efine Cost Rate Ctass Alfocation Factor d Rate R - Residential Service .634783 Rate C - Commercial Service .302805 Rate I- Industrial Service and Rate T- Trans ortation Service .062412 A= Adjustment applied in the current month to correct for the difference between the actual and estimated pipeline cost revenue of the second preceding month, calculated by the formula: A = R - (C - A2), where: R= Actual revenue received from the application of the PP component in the second preceding month. C= Actual pipeline costs for the second preceding month. A2 = The adjustment (A) applied to the PP component in the second preceding month.
