Any payment of principal of or Make‑Whole Amount or interest on this Bond that is due on a day other than a Business Day shall be made on the next succeeding Business Day without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day; provided that if the maturity date of this Bond is a day other than a Business Day, the payment otherwise due on such maturity date shall be made on the next succeeding Business Day and shall include the additional days elapsed in the computation of interest payable on such next succeeding Business Day. For purposes of this paragraph, a “Business Day” is any day, other than a Saturday or Sunday, which is not a day on which commercial banks in New York, New York or Rapid City, South Dakota are required or authorized to be closed.
This Bond shall not be valid or become obligatory for any purpose until the certificate of authentication hereon shall have been signed by the Trustee, or its successor as Trustee, under the Indenture.
This Bond is one of an authorized issue of Bonds of the Company known as its “First Mortgage Bonds,” issued and to be issued in one or more series under, and all equally and ratably secured (except as any sinking, amortization, improvement, renewal or other analogous

-5-


fund, established in accordance with the provisions of the Indenture hereinafter mentioned, may afford additional security for the Bonds of any particular series) by a Restated and Amended Indenture of Mortgage and Deed of Trust, dated as of September 1, 1999, executed by the Company to JPMorgan Chase Bank, N.A. (formerly known as The Chase Manhattan Bank), as Trustee (the successor to which is The Bank of New York Mellon), as supplemented and amended by a First Supplemental Indenture, dated as of August 13, 2002 and as supplemented and amended by a Second Supplemental Indenture, dated as of October 27, 2009 and as further supplemented and amended by a Third Supplemental Indenture, dated as of October 1, 2014 (said Restated Indenture as so supplemented and amended being hereinafter collectively called the “Indenture”), to which Indenture and all further instruments supplemental thereto reference is hereby made for a description of the properties mortgaged and pledged, the nature and extent of the security, the rights of the holders of said Bonds and the coupons appurtenant to coupon Bonds, if any, and of the Trustee and of the Company in respect of such security, and the terms and conditions upon which said Bonds are and are to be issued and secured.
To the extent permitted by the Indenture and as provided therein, with the consent of the Company and upon the written consent or affirmative vote of at least sixty‑six and two‑thirds percent in principal amount of the Bonds then outstanding and entitled to consent, and of not less than sixty‑six and two‑third percent, in principal amount of the Bonds then outstanding and entitled to consent of each series affected thereby in case one or more but less than all of the series of Bonds issued under the Indenture are so affected, the rights and obligations of the Company and of the holders of Bonds and coupons appurtenant to coupon Bonds, if any, and the terms and provisions of the Indenture and of any instrument supplemental thereto may be modified from time to time, provided that no such modification or alteration shall be made which would postpone the date fixed herein or in the Indenture for the payment of the principal of, or any installment of interest on, the Bonds, or reduce the principal of, or the rate of interest payable on, the Bonds, or reduce the percentage of the principal amount of Bonds the consent of which is required for the authorization of any such modification or alteration, without the consent of all of the holders affected thereby. The rights, duties or immunities of the Trustee shall not be modified without the written consent of the Trustee.
As provided in the Indenture, said Bonds are issuable in series which may vary as in the Indenture provided or permitted. This Bond is one of a series of Bonds authorized by the Third Supplemental Indenture and entitled “First Mortgage Bonds, 4.43% Series AG Due October 20, 2044” (the “Bonds of the Series AG”).
As provided in the Indenture, the Bonds of the Series AG are subject to redemption prior to maturity at the option of the Company either as a whole at any time or in part, from time to time, and in certain other cases, at the principal amount of the Bonds so to be redeemed and accrued interest to the date fixed for redemption, together with a premium equal to the Make-Whole Amount, if any (as defined in Section 2.3(d) of the Third Supplemental Indenture). Except as specifically set forth in the Indenture, the Bonds of the Series AG are not subject to optional redemption.
Pursuant to the provisions of Section 8.05 of the Indenture, the Company may request the Trustee to apply moneys deposited with the Trustee (“Trust Moneys”) for various reasons

-6-


toward the redemption of those Bonds, including payment of premium, if applicable, and accrued interest, selected by the Company, provided that there shall be no premium payable in connection with a redemption under Section 8.08 of the Indenture.
Pursuant to the provisions of Section 8.08 of the Indenture, the Bonds of the Series AG are further subject to redemption, in whole or in part, by the Trustee applying certain Trust Moneys which have been held by the Trustee for a period of over two years. Any such redemption is made pro rata among the series of Bonds then outstanding in the ratio of principal amount. Pursuant to the terms of the Third Supplemental Indenture, any redemption under Section 8.08 of the Indenture (and no other Section) shall be at 100 percent of principal (with no premium), plus accrued interest to the redemption date.
Notice of each redemption of the Bonds of the Series AG shall be mailed to all registered owners of the Bonds of the Series AG not less than ten nor more than sixty days before the redemption date.
If this Bond or any portion thereof ($1,000 or a multiple) shall be duly called for redemption as provided in the Indenture, this Bond or such portion thereof shall (unless the Company shall default in the payment of the redemption price) cease to bear interest from and after the date fixed for redemption.
Upon any partial redemption of this Bond, this Bond may, at the option of the registered holder hereof, be either (a) surrendered to the Trustee in exchange for one or more new Bonds of the Series AG for the principal amount of the unredeemed portion of this Bond or (b) submitted to the Trustee for notation hereon by the Trustee of the payment of the portion of the principal hereof so called for redemption.
If an Event of Default, as defined in the Indenture, shall occur and be continuing, the principal of all the Bonds outstanding may become or be declared due and payable, in the manner and with the effect provided in the Indenture. In the event the payment of the Bonds of the Series AG is accelerated pursuant to the Indenture, the aggregate principal amount hereof and interest hereon shall be due and payable together with the Make‑Whole Amount, if any.
The Bonds of the Series AG are issuable as fully registered Bonds without coupons of the denominations of $100,000 and any multiple of $1,000 which may be executed by the Company and delivered to the Trustee for authentication and delivery. The Bonds of the Series AG, upon surrender thereof to the Trustee at its principal corporate trust office in the Borough of Manhattan, The City of New York, are exchangeable for other Bonds of the same series in such authorized denomination or denominations in the same aggregate principal amount, as may be requested by the holders surrendering the same.
The Company and the Trustee may deem and treat the person in whose name this Bond is registered as the absolute owner hereof, for the purpose of receiving payment of or on account of the principal hereof and interest due hereon, and neither the Company nor the Trustee shall be affected by any notice to the contrary. Interest payable hereon on an Interest Payment Date shall be paid to the Person in whose name this Bond is registered at the close of business on the

-7-


April 1 or October 1 (whether or not on a business day) next preceding the Interest Payment Date, except for defaulted interest and unmatured accrued interest on the Bonds of the Series AG called for redemption on a date other than an interest payment date.
No recourse shall be had for the payment of the principal of or the interest on this Bond, or for any claim based hereon or otherwise in respect hereof or of the Indenture or of any indenture supplemental thereto, against any incorporator, stockholder, director or officer, as such, past, present or future, of the Company or of any predecessor or successor corporation, either directly or through the Company or any predecessor or successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or by any legal or equitable proceeding or otherwise howsoever; all such liability being, by the acceptance hereof and as a part of the consideration for the issuance hereof, expressly waived and released by every holder hereof, as more fully provided in the Indenture; provided, however, that nothing herein or in the Indenture contained shall be taken to prevent recourse to and the enforcement of the liability, if any, of any shareholder or any stockholder or subscriber to capital stock upon or in respect of shares of capital stock not fully paid up.

IN WITNESS WHEREOF, the Company has caused this Bond to be signed in its name by its President or one of its Vice Presidents, and its corporate seal to be impressed or imprinted hereon and attested by its Secretary or one of its Assistant Secretaries.

Section 2.2.    Pursuant to the Indenture, the Bonds of the Series AG are subject to redemption, in whole or in part, out of certain monies required to be deposited with the Trustee, but in such cases the redemption shall be effected at the principal amount of the Bonds of the Series AG to be redeemed and accrued interest to the date fixed for redemption, without premium, if redeemed pursuant to Section 8.08 of the Indenture.
Section 2.3.     (a) The Company may, at its option, upon notice as provided below, prepay at any time all, or from time to time any part of, the Bonds of the Series AG at 100% of the principal amount so prepaid, and the Make‑Whole Amount determined for the Settlement Date specified by the Company in such notice with respect to such principal amount. The Company, or the Trustee (at the Company’s written request in the name and at the expense of the Company, which request shall be given to the Trustee at least five Business Days (or such shorter period as shall be acceptable to the Trustee) prior to the latest date that notice of such prepayment must be delivered to the registered owners of the Bonds of the Series AG), will give each registered owner of Bonds of the Series AG written notice (by first class mail or such other method (acceptable to the Trustee) as may be agreed upon by the Company and such registered owner) of each optional prepayment under this Section 2.3(a) not less than 10 days and not more than 60 days prior to the date fixed for such prepayment, to each such registered owner at its last address appearing on the registry books. Each such notice shall specify the Settlement Date (which shall be a Business Day), the aggregate principal amount of the Bonds of the Series AG to be prepaid on such date, the principal amount of each Bond held by such registered owner to be prepaid (determined in accordance with subsection (b) of this Section 2.3), and the interest to be paid on the Settlement Date with respect to such principal amount being prepaid, and shall be accompanied by a certificate signed by a Senior Financial Officer as to the estimated Make‑Whole Amount due in connection with such prepayment (calculated as if the date of such

-11-


notice were the date of the prepayment), setting forth the details of such computation. Two Business Days prior to such Settlement Date, the Company, or the Trustee (at the Company’s written request in the name and at the expense of the Company), shall send to each registered owner of Bonds of the Series AG (by first class mail or by such other method (acceptable to the Trustee) as may be agreed upon by the Company and such registered owner) a certificate signed by a Senior Financial Officer specifying the calculation of such Make‑Whole Amount as of the specified Settlement Date. As promptly as practicable after the giving of the notice and the sending of the certificates provided in this subsection, the Company shall provide a copy of each to the Trustee (unless the Company has elected in writing to have the Trustee deliver such notices and certificates, in which case the Company shall not be required to provide further copies). The Trustee shall be under no duty to inquire into, may conclusively presume the correctness of, and shall be fully protected in relying upon the information set forth in any such notice or certificate. The Bonds of the Series AG are not otherwise subject to voluntary or optional prepayment.
(b)    In the case of each partial prepayment of the Bonds of the Series AG, the principal amount of the Bonds of the Series AG to be prepaid shall be allocated by the Company among all of the Bonds of the Series AG at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts thereof not theretofore called for prepayment; provided that the remaining principal amount of each Bond shall be an authorized denomination.
(c)    In the case of each notice of prepayment of Bonds of the Series AG pursuant to this Section 2.3, if cash sufficient to pay the principal amount to be prepaid on the Settlement Date (which shall be a Business Day), together with interest on such principal amount accrued to such date and the applicable Make‑Whole Amount, if any, is not paid as agreed upon by the Company and each registered owner of the affected Bonds, or, to the extent that there is no such agreement entered into with one or more such owners, deposited with the Trustee on or before the Settlement Date, then such notice of prepayment shall be of no effect. If such cash is so paid or deposited, such principal amount of the Bonds of the Series AG shall be deemed paid for all purposes and interest on such principal amount shall cease to accrue. In case the Company pays any registered owner pursuant to an agreement with that registered owner, the Company shall notify the Trustee as promptly as practicable of such agreement and payment, and shall furnish the Trustee with a copy of such agreement; in case the Company deposits any cash with the Trustee, the Company shall provide therewith a list of the registered owners and the amount of such cash each registered owner is to receive. The Trustee shall be under no duty to inquire into, may conclusively presume the correctness of, and shall be fully protected in relying upon the information set forth in any such notice, list or agreement, and shall not be chargeable with knowledge of any of the contents of any such agreement. Any Bond prepaid in full shall be surrendered to the Company or the Trustee for cancellation (and shall not be reissued) in accordance with Section 9 of the Bond Purchase Agreement referred to in Section 3.3 of this Third Supplemental Indenture.
(d)    “Make‑Whole Amount” means, with respect to any Bonds of the Series AG, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Bonds of the Series AG over the amount of such Called Principal, provided that the Make‑Whole Amount may in no event be less than zero.

-12-


For the purposes of determining the Make‑Whole Amount, the following terms have the following meanings:
“Business Day” means any day other than a Saturday, a Sunday or a day on which commercial banks in New York City are required or authorized to be closed.
“Called Principal” means, with respect to any Bonds of the Series AG, the principal of such bond that is to be prepaid pursuant to subsection (a) of this Section 2.3 or has become or is declared to be immediately due and payable pursuant to Article Eleven of the Indenture, as the context requires.
“Discounted Value” means, with respect to the Called Principal of any Bonds of the Series AG, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Bonds of the Series AG is payable) equal to the Reinvestment Yield with respect to such Called Principal.
“Reinvestment Yield” means, with respect to the Called Principal of any Bonds of the Series AG, 0.50% over the yield to maturity implied by (i) the yields reported as of 10:00 a.m. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded U.S. Treasury securities having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable (including by way of interpolation), the Treasury Constant Maturity Series Yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (519) (or any comparable successor publication) for actively traded U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. Such implied yield will be determined, if necessary, by (a) converting U.S. Treasury bill quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between (1) the actively traded U.S. Treasury security with the maturity closest to and greater than such Remaining Average Life and (2) the actively traded U.S. Treasury security with the maturity closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Bonds of the Series AG.
“Remaining Average Life” means, with respect to any Called Principal, the number of years (calculated to the nearest one‑twelfth year) obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years (calculated to the nearest one‑twelfth year) that will elapse

-13-


between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment.
“Remaining Scheduled Payments” means, with respect to the Called Principal of any Bonds of the Series AG, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms of the Bonds of the Series AG, then (for the purpose of this calculation) the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date.
“Senior Financial Officer” means the chief financial officer, principal accounting officer, treasurer or controller of the Company.
“Settlement Date” means, with respect to the Called Principal of any Bonds of the Series AG, the date on which the principal of such Bonds is to be prepaid pursuant to subsection (a) of this Section 2.3 or is declared to be immediately due and payable pursuant to Article Eleven of the Indenture, as the context requires.
The words “prepay”, “prepaid” and “prepayment”, as used in this Section 2.3, shall mean “redeem”, “redeemed” and “redemption”, as those terms are used in the Indenture, the term “Settlement Date”, as used in this Section 2.3, shall mean “redemption date”, “date of redemption” and any similar term, as those terms are used in the Indenture and the prepayment price provided for in this Section 2.3 shall mean “redemption price” for purposes of the Indenture. Any prepayment under this Section 2.3 shall be made in accordance with Article Ten of the Indenture except to the extent Section 2.3 shall provide otherwise.
Section 2.4.    The Company will not and will not permit any Affiliate to purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Bonds of the Series AG except upon the payment or prepayment of the Bonds of the Series AG in accordance with the terms of this Third Supplemental Indenture and the Bonds of the Series AG. The Company will promptly cancel all Bonds of the Series AG acquired by it or any Affiliate pursuant to any payment or prepayment of Bonds pursuant to any provision of this Third Supplemental Indenture and no Bonds of the Series AG may be issued in substitution or exchange for any such Bonds.
Section 2.5.        All monies paid to the Trustee pursuant to Sections 2.2 and 2.3 of this Article II shall be held by the Trustee in trust for the benefit of the respective registered owners of the Bonds of the Series AG which are to be redeemed (in whole or in part) and shall be paid to them as provided in Article Ten of the Indenture.
Section 2.6.        Nothing contained in the Indenture or in any Bond shall be construed to imply any obligation upon the Trustee to make any payment, except out of monies deposited with it for such purpose by the Company.

-14-
