TUCSON ELECTRIC POWER COMPANY
1.500% SENIOR NOTE DUE 2030
Tucson Electric Power Company, a corporation duly organized and existing under the laws of the State of Arizona (herein referred to as the “Company,” which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to _________________, or registered assigns, the principal sum of _________________________ Dollars ($___________) on August 1, 2030, and to pay interest on said principal sum semi-annually on February 1 and August 1 of each year commencing February 1, 2021 (each an Interest Payment Date) at the rate of 1.500% per annum, until the principal hereof is paid or made available for payment and to pay interest on any overdue principal and, to the extent permitted by law, interest, at the rate then borne by the Securities of this series.  Interest on the Securities of this series will accrue from, and include, August 10, 2020, to the first Interest Payment Date, and thereafter will accrue from the last Interest Payment Date to which interest has been paid or duly provided for.  In the event that any Interest Payment Date 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 such delay) with the same force and effect, and in the same amount, as if made on the Interest Payment Date.  The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the close of business on (i) the Business Day next preceding such Interest Payment Date so long as the Securities are held by a securities depository in book-entry form, or (ii) if the Securities are not held by a securities depository in book‐entry form, the 15th calendar day next preceding such Interest Payment Date, provided, however, that interest payable at Maturity will be paid to the Person to whom principal is paid.

Payment of the principal of and premium, if any, and interest on this Security will be made upon presentation at the office or agency of the Company maintained for that purpose in the City of New York, the State of New York in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts, provided, however, that, at the option of the Company, the principal of and premium, if any, and interest on this Security may be paid by check mailed to the address of the person entitled thereto, as such address shall appear on the Security Register or by wire transfer to an account designated by the person entitled thereto; and provided, further, that, after payment in full of this Security the Holder shall promptly surrender this Security at the office or agency of the Company in the City of New York, the State of New York.
Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

[FORM OF REVERSE OF NOTE]
General.
    
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture (For Unsecured Debt Securities), dated as of November 1, 2011 (herein, together with any amendments thereto, called the “Indenture,” which term shall have the meaning assigned to it in such instrument), between the Company and U.S. Bank National Association, as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture, including the Board Resolutions and Officer’s Certificate filed with the Trustee on August 10, 2020 creating the series designated on the face hereof, for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered.


Optional Redemption.


At any time prior to May 1, 2030, the Securities of this series will be redeemable at the option of the Company (each a “Redemption Date”), in whole or in part, on not less than 30 nor more than 60 days’ notice prior to the Redemption Date.  If the Company redeems all or any part of the Securities of this series, it will pay a Redemption Price (the “Redemption Price”) equal to the greater of:


(1) 100% of the principal amount of the Securities of this series being redeemed, and
(2) the sum of the present values of the remaining scheduled payments of principal of and interest on the Securities of this series being redeemed (assuming, for this purpose, that the Securities of this series were stated to mature on May 1, 2030 and excluding the portion of any such interest accrued to the Redemption Date), discounted (for purposes of determining such present values) to the Redemption Date on a semi-annual basis (assuming a 360‐day year consisting of twelve 30‐day months) at the Adjusted Treasury Rate plus 15 basis points, all as determined by the Independent Investment Banker,
plus, in each case, accrued and unpaid interest on the Securities of this series being redeemed to the Redemption Date.
At any time on or after May 1, 2030, the Securities of this series will be redeemable at the option of the Company, in whole or in part, on not less than 30 nor more than 60 days’ notice prior to the Redemption Date, at the Redemption Price equal to 100% of the principal amount of the Securities of this series to be redeemed, plus accrued and unpaid interest thereon to the Redemption Date.
“Adjusted Treasury Rate” means, with respect to any Redemption Date:


4







(1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the remaining term of the Securities of this series (assuming, for this purpose, that the Securities of this series were stated to mature on May 1, 2030), yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month); or 
(2) if such release (or any successor release) is not published during the week preceding the calculation date for the Adjusted Treasury Rate or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.  
The Adjusted Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date.
“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a maturity comparable to the remaining term of the Securities of this series (assuming, for this purpose, that the Securities of this series were stated to mature on May 1, 2030) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to such remaining term of the Securities of this series (assuming, for this purpose, that the Securities of this series were stated to mature on May 1, 2030).
“Comparable Treasury Price” means, with respect to any Redemption Date, (1) the average of five Reference Treasury Dealer Quotations for such Redemption Date after excluding the highest and lowest such Reference Treasury Dealer Quotations or (2) if the Independent Investment Banker obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations.
“Independent Investment Banker” means one of the Reference Treasury Dealers that the Company appoints to act as the Independent Investment Banker from time to time or, if any of such firms are unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the Company.
“Reference Treasury Dealer” means a primary U.S. Government securities dealer appointed by the Company.


5







“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date.
The Company shall deliver to the Trustee before any Redemption Date for the Securities of this series its calculation of the Redemption Price applicable to such redemption.  The Trustee shall be under no duty to inquire into, may presume the correctness of, and shall be fully protected in acting upon the Company’s calculation of any Redemption Price of the Securities of this series.
In lieu of stating the Redemption Price, notices of redemption of the Securities of this series pursuant to the first paragraph under “Optional Redemption” shall state substantially the following:  “The Redemption Price of the Securities of this series to be redeemed shall equal the sum of (a) the greater of (i) 100% of the principal amount of such Securities of this series, or (ii) as determined by the Independent Investment Banker, the sum of the present values of the remaining scheduled payments of principal of and interest on the Securities of this series being redeemed (excluding the portion of any such interest accrued to the Redemption Date), discounted (for purposes of determining such present values) to the Redemption Date on a semi-annual basis (assuming a 360‐day year consisting of twelve 30‐day months) at the Adjusted Treasury Rate plus 15 basis points.”
If less than all of the Securities of this series are to be redeemed consistent with the terms hereof, the particular Securities to be redeemed shall be selected by the Trustee from the Outstanding Securities of such series in a manner it deems fair and appropriate.
If at the time notice of redemption is given, the redemption moneys are not on deposit with the Trustee, then the redemption shall be subject to their receipt on or before the Redemption Date and such notice shall be of no effect unless such moneys are received.
Upon payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Securities of this series or portions thereof called for redemption.
The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security upon compliance with certain conditions set forth in the Indenture including the Officer’s Certificate described above.

The Indenture contains provisions permitting the Holders of a majority in aggregate principal amount of the Securities of all series then Outstanding to waive compliance by the Company with certain provisions of the Indenture.

Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of a majority in aggregate principal amount of the Securities of all series at the time Outstanding in respect of which an Event of Default shall have occurred and be continuing shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity satisfactory to it against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of a majority in aggregate principal amount of Securities of all series at the time Outstanding in respect of which an Event of Default shall have occurred and be continuing a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity.  The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.
