Exhibit 10.1

Execution Version

FOURTH AMENDMENT TO REVOLVING CREDIT AGREEMENT

THIS FOURTH AMENDMENT TO REVOLVING CREDIT AGREEMENT (this “Amendment”), is made
and entered into as of August 22, 2014 by and among ATMOS ENERGY CORPORATION, a
Texas and Virginia corporation (the “Borrower”), the several banks and other
financial institutions from time to time party hereto (collectively, the
“Lenders”) and THE ROYAL BANK OF SCOTLAND PLC, in its capacity as Administrative
Agent for the Lenders (the “Administrative Agent”).

W I T N E S S E T H:

WHEREAS, the Borrower, the Lenders and the Administrative Agent are parties to a
certain Revolving Credit Agreement, dated as of May 2, 2011 (as amended,
restated, supplemented or otherwise modified from time to time, the “Credit
Agreement”; capitalized terms used herein and not otherwise defined shall have
the meanings assigned to such terms in the Credit Agreement), pursuant to which
the Lenders have made certain financial accommodations available to the
Borrower;
WHEREAS, the Borrower has notified the Administrative Agent and each of the
Lenders that the Borrower proposes to increase the Aggregate Commitment Amount
under the Credit Agreement by the amount of $300,000,000 which increase shall be
made without using the existing $250,000,000 uncommitted incremental facility
set forth in Section 2.21 of the Credit Agreement;

WHEREAS, certain Lenders have agreed to increase their Commitments as requested
by the Borrower and the Credit Agreement will continue to contemplate an up to
$250,000,000 uncommitted incremental facility set forth in Section 2.21 of the
Revolving Credit Agreement that may be used in addition to the incremental
Commitments provided below; and

WHEREAS, the Borrower has also requested that the Lenders and the Administrative
Agent amend certain provisions of the Credit Agreement, including an extension
of the term of the Commitments and reduction in pricing related thereto, and
subject to the terms and conditions hereof, the Lenders are willing to do so;

NOW, THEREFORE, for good and valuable consideration, the sufficiency and receipt
of all of which are acknowledged, the Borrower, the Lenders and the
Administrative Agent agree as follows:

1.Increase in Commitments. Each of the parties hereto consents to the increase
in the aggregate principal amount of the Commitments to $1,250,000,000. Each
Lender executing this Amendment agrees that, effective as of the Fourth
Amendment Date (defined below), its Commitment is in the amount set forth on
Schedule II. Each of the parties acknowledges and agrees that the Commitments of
each of the Lenders are several and not joint commitments and obligations of
such Lender. Immediately after giving effect to this Amendment, the outstanding
Borrowings shall be reallocated ratably based upon the Commitments as set forth
on Schedule II. Each of the parties hereto acknowledges and agrees that the
foregoing increase in the Commitments is independent of Section 2.21 of the
Credit Agreement, and the Borrower retains the right to further increase the
Commitments by up to $250,000,000 after the Fourth Amendment Date on the terms
set forth in Section 2.21 of the Credit Agreement.

--------------------------------------------------------------------------------

such later date to which such Lender has agreed to extend its Revolving
Commitment pursuant to Section 2.23, (ii) the date on which the Commitments are
terminated pursuant to Section 2.6 and (iii) the date on which all amounts
outstanding under this Agreement have been declared or have automatically become
due and payable (whether by acceleration or otherwise).

following definition of “Fourth Amendment Date” in its entirety in the

Borrower, together with certificates of good standing or existence, as may be

The credit ratings to be utilized for purposes of this Schedule are those
assigned to the senior, unsecured long-term debt securities of the Borrower
without third-party credit enhancement, whether or not any such debt securities
are actually outstanding, and any rating assigned to any other debt security of
the Borrower shall be disregarded. The rating in effect on any date is that in
effect at the close of business on such date. If the ratings established or
deemed to have been established by Moody’s, S&P and Fitch for the Borrower fall
within different Levels, the highest rating (or numerically lower Level) shall
apply, unless the ratings differ by more than one Level, in which case, if the
rating is the same by two rating agencies, and the third agency rating is lower,
then the higher rating shall govern and otherwise, the governing rating shall be
the rating next below the highest of the three. If the Borrower is not rated by
Moody’s, S&P or Fitch, then the rate shall be established by reference to Level
V.
If the rating system of Moody’s, S&P or Fitch shall change, or if any of these
rating agencies shall cease to be in the business of rating corporate debt
obligations, the Borrower, the Lenders and the Administrative Agent shall
negotiate in good faith to amend this Schedule to reflect such changed rating
system or the unavailability of ratings from such rating agency and, pending the
effectiveness of any such amendment, the Applicable Margin and the Applicable
Percentage shall be determined by reference to the rating most recently in
effect prior to any such change or cessation. If after a reasonable time (not to
exceed 90 days) the parties cannot agree to a mutually acceptable amendment, the
Applicable Margin and the Applicable Percentage shall be determined by reference
to Level V.
