MASTER EXTENSION, NEW COMMITMENT AND AMENDMENT AGREEMENT

Reference is made to the Third Amended and Restated Credit Agreement dated as of November 18, 2016, as amended, modified, extended or restated from time to time (the “Credit Agreement”) among AutoZone, Inc., the Lenders party thereto, Bank of America, N.A., as Administrative Agent and JPMorgan Chase Bank, N.A., as Syndication Agent. Terms defined in the Credit Agreement are used in this Master Extension, New Commitment and Amendment Agreement (this “Agreement”) with the same meanings.

1. Each undersigned Lender hereby confirms its Revolving Commitment, effective as of the Effective Date set forth below, to make Loans under the Credit Agreement up to the principal amount of such Revolving Commitment as set forth on Schedule 2.1(a) attached hereto and, if applicable, agrees that its existing Revolving Commitment is hereby replaced. In order to effect the modified Revolving Commitments of the Lenders as of the Effective Date, assignments of Revolving Commitments shall be deemed to be made among the applicable Lenders in such amounts as may be necessary, and with the same force and effect as if such assignments of Revolving Commitments were evidenced by Assignment and Assumptions (but without the payment of any related assignment fee), and no other notices, consents, or documents shall be required in connection with such assignments (all of which, to the extent otherwise required are hereby waived). If the undersigned Lender is not already a Lender under the Credit Agreement, such Lender hereby acknowledges, agrees and confirms that, by its execution of this Agreement, such Lender will, as of the Effective Date, be a party to the Credit Agreement and be bound by the provisions of the Credit Agreement and, to the extent of its Revolving Commitment, have the rights and obligations of a Lender thereunder. The parties hereto acknowledge and agree that this Agreement constitutes (x) a New Commitment Agreement substantially in the form of Schedule 3.4(b) to the Credit Agreement and (y) an Assignment and Assumption substantially in the form of Schedule 10.3(a) to the Credit Agreement. For the avoidance of doubt, with respect to any Lender whose Revolving Commitment as of the Effective Date is zero, such Lender shall, as of the Effective Date, be released from its obligations under the Credit Agreement (and cease to be a party thereto), except for those obligations of Lenders in respect of expense reimbursement and indemnification which by their express terms survive termination of the Commitments, but shall continue to be entitled to the benefits of Sections 3.9, 3.10 and 3.11 of the Credit Agreement with respect to facts and circumstances occurring prior to the Effective Date.

2. Furthermore, each undersigned Lender (together constituting Required Lenders under the Credit Agreement), the Borrower and the Administrative Agent agree that (a) the $400,000,000 increase option pursuant to Section 3.4(b) of the Credit Agreement is hereby “refreshed” as of the Effective Date, (b) to that end, the references to “$400,000,000” and “$2,000,000,000” set forth in Section 3.4(b)(i) of the Credit Agreement are hereby amended to read “$800,000,000 (inclusive of the $400,000,000 increase to the Revolving Committed Amount effective as of November 18, 2017)” and “$2,400,000,000,” respectively, (c) in Section 3.4(d) of the Credit Agreement, the words “up to two (2) written requests” are hereby replaced with the following “make one written request” and (d) in Section 3.4(d) of the Credit Agreement, the words “(x) in the case of the first such request, no earlier than 60 days prior to the first anniversary of the Closing Date, but no later than 45 days prior to the first anniversary of the Closing Date and (y) in the case of the second such request,” are hereby deleted.

3. Each undersigned Lender hereby agrees that (a) pursuant to Section 3.4(d) of the Credit Agreement and effective as of the Effective Date, the Termination Date relating to its Commitment is extended by one (1) year to November 18, 2022 and (b) the definition of “Termination Date” in Section 1.1 of the Credit Agreement is amended to replace the reference to “November 18, 2021” with a reference to “November 18, 2022.”

4. The parties hereto agree that, effective as of the Effective Date, Schedule 2.1(a) to the Credit Agreement is restated in its entirety to read as set forth on Schedule 2.1(a) attached hereto. The Borrower hereby ratifies and reaffirms the Credit Agreement, as amended hereby, and the other Credit Documents and acknowledges and reaffirms that, after giving effect to the increase in the Revolving Commitments pursuant to this Agreement and the other amendments contained herein, it is bound by all terms of this Credit Agreement and the other Credit Documents.

5. The Borrower agrees to pay on the Effective Date all fees and expenses relating to this Agreement which are due and payable on such date, including all reasonable out-of-pocket costs and expenses of the Administrative Agent in connection with the preparation, execution and delivery of this Amendment (including, without limitation, the reasonable fees and expenses of Moore & Van Allen PLLC, special counsel to the Administrative Agent).

6. Subject to (a) receipt by the Administrative Agent of (i) executed signature pages to this Agreement from the Borrower, each Lender party hereto (which, for the avoidance of doubt, must constitute Required Lenders) and the Administrative Agent and (ii) the items required to be delivered by the Borrower pursuant to clauses (A), (C) and (D) of Section 3.4(b)(ii) of the Credit Agreement (to the extent applicable), and (b) payment by the Borrower of the fees set forth in Section 5 above, the Effective Date of the extensions and new Revolving Commitments pursuant to this Agreement shall be November 18, 2017 (the “Effective Date”).

7. Nothing contained in this Agreement shall be deemed to constitute a waiver of any rights or remedies the Administrative Agent or any Lender may have under the Credit Agreement or any other Credit Documents or under applicable law.

8. This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

9. This Agreement shall constitute a Credit Document.

10. This Agreement may be executed in any number of counterparts, each of which where so executed and delivered shall be an original, but all of which shall constitute one and the same instrument. It shall not be necessary in making proof of this Agreement to produce or account for more than one such counterpart. Delivery of an executed counterpart of a signature page by telecopy, “pdf” or other electronic imaging means shall be effective as delivery of a manually executed counterpart.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed as of the date first written above.
