This TWELFTH SUPPLEMENTAL INDENTURE, dated as of August 25, 2011, is between Arizona Public Service Company, a corporation duly organized and existing under the laws of the State of Arizona (herein called the “Company”), having its principal office at 400 North Fifth Street, Phoenix, Arizona 85004, and The Bank of New York Mellon Trust Company, N.A., successor to JPMorgan Chase Bank, N.A. (formerly known as The Chase Manhattan Bank), a national banking association, as Trustee (herein called the “Trustee”) under the Indenture dated as of January 15, 1998 between the Company and the Trustee (the “Indenture”).

Pursuant to the terms of the Indenture, the Company desires to provide for the establishment of a new series of its Securities to be known as its 5.05% Notes due 2041 (herein called the “Notes”), the forms and substance of such Notes and the terms, provisions, and conditions thereof to be set forth as provided in the Indenture and this Twelfth Supplemental Indenture.
All things necessary to make this Twelfth Supplemental Indenture a valid agreement of the Company, and to make the Notes described herein, when executed by the Company and authenticated and delivered by the Trustee, the valid obligations of the Company, have been done.
NOW, THEREFORE, THIS TWELFTH SUPPLEMENTAL INDENTURE WITNESSETH:
For and in consideration of the premises and the purchase of the Notes by the Holders thereof, and for the purpose of setting forth, as provided in the Indenture, the form and substance of each of the Notes and the terms, provisions, and conditions thereof, it is mutually agreed, for the equal and proportionate benefit of all Holders of the Notes, as applicable, as follows:
ARTICLE ONE

GENERAL TERMS AND CONDITIONS OF THE NOTES

SECTION 101.    Authentication and Delivery. There shall be and is hereby authorized a series of Securities designated the “5.05% Notes due 2041” initially limited in aggregate principal amount to $300,000,000, which amount shall be as set forth in any Company Order for the authentication and delivery of Notes. The Notes shall mature and the principal shall be due and payable together with all accrued and unpaid interest thereon on September 1, 2041, and the Notes shall be issued in the form of registered Securities without coupons.

1
13602893.1



The foregoing principal amount of the Notes may be increased from time to time as permitted by Section 301 of the Indenture. All Notes need not be issued at the same time and such series may be reopened at any time, without notice to, or the consent of, the then existing Holders, for issuance of additional Notes. Any such additional Notes will be equal in rank and have the same respective maturity, payment terms, redemption features, and other terms as the Notes initially issued, except for the issue date, public offering price, payment of interest accruing prior to the issue date, and first payment of interest following the issue date of the additional Notes.
SECTION 102.    Global Security. The Notes shall be issued in certificated form, except that the Notes shall be issued initially as a Global Security to and registered in the name of Cede & Co., as nominee of The Depository Trust Company, as Depositary therefor. Any Notes to be issued or transferred to, or to be held by, Cede & Co. (or any successor thereof) for such purpose shall bear the depositary legend in substantially the form set forth at the top of the form of Note in Section 301 hereof (in lieu of that set forth in Section 204 of the Indenture), unless otherwise agreed by the Company, such agreement to be confirmed in writing to the Trustee. Each such Global Security may be exchanged in whole or in part for Notes registered, and any transfer of such Global Security in whole or in part may be registered, in the name(s) of Persons other than such Depositary or a nominee thereof only under the circumstances set forth in clause (2) of the last paragraph of Section 305 of the Indenture, or such other circumstances in addition to or in lieu of those set forth in clause (2) of the last paragraph of Section 305 of the Indenture as to which the Company shall agree, such agreement to be confirmed in writing to the Trustee. Upon the occurrence of any such event, the Notes will be issued in such names as the Depositary shall instruct the Trustee.
SECTION 103.     Place of Payment and Place for Registration of Transfers and Exchange. Principal of, and premium, if any, and interest on, the Notes will be payable, the transfer of Notes will be registrable and the Notes will be exchangeable for Notes bearing identical terms and provisions, at the office or agency of the Company in the Borough of Manhattan, The City and State of New York; provided, however, that payment of interest may be made at the option of the Company by wire transfer to any Holder or by deposit to the account of the Holder of any such Notes if such account is maintained with the Trustee, in each case according to the written instructions given by such Holder on or prior to the applicable record date to the Trustee, which written instructions shall remain in effect until revised by such Holder by an instrument in writing delivered to the Trustee.
SECTION 104.    Payment of Interest. The Notes will bear interest at the rate of 5.05% per annum from August 25, 2011 or from the most recent Interest Payment Date (as hereinafter defined) to which interest has been paid or duly provided for until the principal thereof is paid or made available for payment, payable on March 1 and September 1 of each year (each, an “Interest Payment Date”), commencing on March 1, 2012, to the person in whose name such Note or any Predecessor Security is registered, at the close of business on February 15 and August 15, as the case may be, whether or not a Business Day, immediately preceding the Interest Payment Date. Any such interest installment not punctually paid or duly provided for shall forthwith cease to be payable to the Holders on such Regular Record Date, and may be paid to the Person in whose name such Note (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date to be fixed by the Trustee for the payment of such Defaulted Interest, notice whereof

2
13602893.1



shall be given to the Holders of the Notes not less than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully described in the Indenture.
The amount of interest payable for any period will be computed on the basis of a 360-day year of twelve 30-day months. Interest will accrue from August 25, 2011 or from the most recent Interest Payment Date to which interest has been paid or duly provided for to, but not including, the relevant payment date. In the event that any date on which interest is payable on the Notes is not a Business Day, then payment of interest payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay), in each case with the same force and effect as if made on such date. A “Business Day” shall mean any day except a Saturday, a Sunday or a legal holiday in The City of New York on which banking institutions are authorized or required by law, regulation or executive order to close.
SECTION 105.    Redemption of the Notes. The Company may redeem all or any portion of the Notes, at its option, at any time or from time to time, upon notice as provided in the Indenture. The Redemption Price for any of the Notes to be redeemed on any Redemption Date prior to March 1, 2041 will be equal to the greater of the following amounts:
(a)    100% of the principal amount of the Notes being redeemed on the Redemption Date; or
(b)    the sum of the present values of the remaining scheduled payments of principal and interest on the Notes being redeemed on that Redemption Date (not including any portion of any payments of interest accrued to the Redemption Date) discounted to the Redemption Date on a semiannual basis at the Adjusted Treasury Rate plus 25 basis points as determined by a Reference Treasury Dealer appointed by the Company for such purpose;
plus, in each case, accrued and unpaid interest thereon to the Redemption Date. The Redemption Price for any of the Notes to be redeemed on any Redemption Date on or after March 1, 2041 will be equal to 100% of the principal amount of the Notes being redeemed on the Redemption Date plus accrued and unpaid interest thereon to the Redemption Date.
Notwithstanding the foregoing, installments of interest on the Notes that are due and payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable on the Interest Payment Date to the Holders as of the close of business on the relevant record date in accordance with the terms of such Notes and the Indenture.

The Company shall give the Trustee written notice of the Redemption Price, promptly after the calculation thereof.
The Trustee shall be under no duty to inquire into, may conclusively presume the correctness of, and shall be fully protected in acting upon, the Company’s calculation of any Redemption Price.
