AMENDMENT NO. 1

TO

ASSET PURCHASE AGREEMENT

THIS AMENDMENT NO. 1 TO ASSET PURCHASE AGREEMENT (“Amendment”) is made and entered into as of August 1, 2012, by and between Atmos Energy Corporation, a corporation incorporated in the State of Texas and the Commonwealth of Virginia (“Seller”), and Liberty Energy (Midstates) Corp., a Missouri corporation (“Buyer”), and amends that certain Asset Purchase Agreement, dated May 12, 2011 (the “Agreement”), by and between the parties.

WHEREAS, Seller and Buyer entered into the Agreement on May 12, 2011;

WHEREAS, pursuant to Section 11.1 of the Agreement, Seller and Buyer now desire to amend certain provisions of the Agreement in the manner set forth herein.

NOW THEREFORE, in consideration of the parties’ respective covenants, representations, warranties, and agreements hereinafter set forth, and intending to be legally bound hereby, the parties agree as follows:

1. Amended Agreement. The Agreement is amended as follows:

(a) Subsection (b) of Section 2.1 (Purchased Assets) of the Agreement is amended by deleting all existing text of that subsection in its entirety and substituting the following text in its entirety:

“all Billed Revenues and Unbilled Revenues, each as defined in Section 3.5, which for the avoidance of doubt and notwithstanding any other provision of this Agreement to the contrary, shall constitute Current Assets for purposes of calculating the Adjustment Amount;”

(b) Subsection (a) of Section 2.2 (Excluded Assets) of the Agreement is amended by deleting all existing text of that subsection in its entirety and substituting the word “Reserved”.

(c) Section 3.5 (Unbilled Revenues) of the Agreement is amended by deleting all existing text of that subsection in its entirety and substituting the following text in its entirety:

“On and prior to the Closing Date, Seller shall read all customer meters in their normal cycle and in due course render the related bills to its customers served by the Business. Seller shall also read each daily read transportation customer meter (collectively, “Large Volume Meters”) on the day immediately preceding the Closing Date. Seller shall provide Buyer with the last meter reading from each of the Large Volume Meters made on the day immediately preceding the Closing Date as soon as practicable after the Closing Date. After the Closing Date, Buyer shall read the customer meters for their first time, in the normal cycle, and in due course render bills for service during the period between Seller’s last reading in the normal cycle and Buyer’s first reading in the normal cycle to the customers served by the Business. Buyer shall determine the volume of gas sold by Seller prior to the Closing Date through Large Volume Meters by Seller’s meter readings on the day immediately preceding the Closing Date. Buyer shall determine by allocation

the volumes of gas sold through all meters other than Large Volume Meters, by Seller prior to the Closing Date, and by Buyer on and after the Closing Date and prior to its first meter reading, through meters without charts. Such allocation shall be consistent with Seller’s past practices for unbilled revenues. The receivables related to the volume of gas allocable to Seller under this Section but not yet billed to customers served by the Business shall be defined as “Unbilled Revenue.” “Billed Revenue” shall mean all outstanding bills to customers served by the Business that have not been paid as of the Closing Date less (i) any offset that results from the difference between installment payments and gas consumed and (ii) allowance for bad debt, which shall be calculated consistent with Seller’s past practices.”

(d) Subsection (e) of Section 7.10 (Employee Benefits) of the Agreement is amended by deleting all existing text of that subsection in its entirety and substituting the following text in its entirety:

“Seller shall fully vest all Transferred Employees in their account balances under Seller’s Retirement Savings Plan (the “Seller’s 401(k) Plan”), effective as of the Closing Date. Effective as of the Closing Date, Buyer shall maintain or designate, or cause to be maintained or designated, a defined contribution plan and related trust intended to be qualified under Sections 401(a), 401(k) and 501(a) of the Code (the “Buyer’s 401(k) Plan”). Effective as of the Closing Date, the Transferred Employees shall cease participation in Seller’s 401(k) Plan, and shall commence participation in Buyer’s 401(k) Plan. The Buyer’s 401(k) Plan shall provide for the receipt from Transferred Employees of “eligible rollover distributions” (as such term is defined under Section 402 of the Code), including rollovers of outstanding plan loans under the Seller’s 401(k) Plan (and all assets and liabilities associated thereto). As soon as practicable following the Closing Date, Buyer shall provide Seller with such documents and other information as Seller shall reasonably request to assure itself that the Buyer’s 401(k) Plan is tax-qualified and provides for the receipt of eligible rollover distributions. Each Transferred Employee shall be given the opportunity to receive a distribution of his or her account balance under Seller’s 401(k) Plan and shall be given the opportunity to elect a direct rollover of such account balance, including the rollover of any outstanding plan loans, to the Buyer’s 401(k) Plan, subject to and in accordance with the provisions of such plan and applicable Law. Seller and Buyer shall cooperate in order to facilitate any such distribution or rollover and to effect an eligible rollover distribution for those Transferred Employees who elect to rollover their account balances directly to the Buyer’s 401(k) Plan. With respect to each Transferred Employee who elects to effect an eligible rollover distribution of their account balances to the Buyer’s 401(k) Plan and has an outstanding plan loan under Seller’s 401(k) Plan as of the Closing Date, Seller and Buyer shall cooperate to take such steps as may be necessary to (i) name the trustee of the Buyer’s 401(k) Plan as the obligee of such loan, (ii) obtain an executed written acknowledgement from such Transferred Employee that Buyer’s Plan will be the obligee of such loan, and (iii) permit any such Transferred Employee to make timely loan service payments to Buyer’s 401(k) Plan through payroll deductions by Buyer (or its applicable Affiliate) on or after completion of

2

the eligible rollover distribution. On and after the Closing Date and prior to the completion by any Transferred Employee of an eligible rollover distribution which includes the rollover of an outstanding plan loan, Buyer and Seller shall cooperate to permit such Transferred Employee to make timely loan service payments to Seller’s 401(k) Plan through payroll deductions by Buyer (or its applicable Affiliate).”

(e) Section 8.2 (Conditions to Buyer’s Closing Obligations) of the Agreement is amended by adding a new Subsection (i) following the existing text of that section, which new Subsection (i) shall read in its entirety:

“A FERC waiver effectuating the transfer of transportation capacity to Buyer will be obtained prior to the Closing, or, if a waiver is not obtained prior to the Closing, the Parties shall ensure that the transportation capacity pricing and service to which Seller is currently entitled is preserved through the transaction.”

(f) Subsection (b)(ii) of Section 1 (Adjustment Amount) of Appendix A to the Agreement is amended by deleting all existing text of that subsection in its entirety and substituting the following text in its entirety:

““Regulatory Liabilities” means the Value as of the Effective Time of the FERC Accounts related to liabilities to refund or credit amounts to customers through rates and charges in future periods (together with any interest or return thereon), that result specifically from ratemaking action by the Applicable Commission (whether pursuant to a decrease or offset to rate base for ratemaking purposes or pursuant to an authorized recovery or credit mechanism), that are included in Assumed Obligations as of the Effective Time or are imposed on Buyer by any Applicable Commission for rate purposes in connection with the approval of the transaction (and excluding any amounts included in the Closing Net PPE Amount); provided that the rate base offset required pursuant to that certain Unanimous Stipulation and Agreement in Case No. GM-2012-0037 before the Public Service Commission of the State of Missouri (the “Missouri Rate Base Offset”) shall, in no circumstance, constitute a Regulatory Liability or affect the calculation of Regulatory Liabilities. For the avoidance of doubt, notwithstanding any provision of the Agreement to the contrary, the Missouri Rate Base Offset shall not affect the calculation of the Adjustment Amount, and the Purchase Price shall not be increased, decreased or otherwise adjusted in respect of the Missouri Rate Base Offset.”

(g) The Schedules to the Agreement, other than the Seller Disclosure Schedules, are amended by deleting all existing such Schedules in their entirety and substituting the Schedules of corresponding numbers attached to this Amendment.

2. Miscellaneous.

(a) Capitalized Terms. Unless otherwise defined herein, each of the capitalized terms used herein, but not defined herein, shall have the same meaning given to such term in the Agreement. Terms defined herein that are used in an amended provision of the Agreement shall have the same meaning as their definitions herein.

3

(b) Entire Agreement. This Amendment will be a valid and binding agreement of the parties only if and when it is fully executed and delivered by the parties, and until such execution and delivery no legal obligation will be created by virtue hereof or any discussions with respect hereto. This Amendment embodies the entire agreement and understanding of the parties hereto in respect of the matters contemplated by this Amendment. This Amendment supersedes all prior agreements and understandings between the parties with respect to such matters contemplated hereby.

(c) Ratification; Interpretation. Except as specifically amended by this Amendment, the Agreement remains in effect in accordance with all terms and conditions contained therein. For the avoidance of doubt, the phrases “as of the date hereof”, “as of the date of this Agreement” or words of similar import as used in the Agreement (as amended pursuant to this Amendment) shall mean “as of May 12, 2011” (i.e., the date the Agreement was executed).

(d) Amendment. This Amendment may be amended, modified, or supplemented only by written agreement of Seller and Buyer.

(e) Governing Law. This Amendment (as well as any claim or controversy arising out of or relating to this Amendment or the transactions contemplated hereby) shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflicts of laws rules thereof that would otherwise require the laws of another jurisdiction to apply.

(f) Delivery. This Amendment may be executed in multiple counterparts (each of which will be deemed an original, but all of which together will constitute one and the same instrument), and may be delivered by facsimile transmission, with such facsimile signature constituting an original for all purposes.
