To the extent permitted by, and as provided in the Indenture, modifications or alterations of the Indenture or of any indenture supplemental thereto, and of the rights and obligations of the Company and of the holders of the Bonds and coupons, may be made with the consent of the Company by an affirmative vote of not less than 60% in principal amount of the Bonds entitled to vote then outstanding, at a meeting of holders of the Bonds called and held as provided in the Indenture, and by an affirmative vote of not less than 60% in principal amount of the Bonds of any series entitled to vote then outstanding and affected by such modification or alteration, in case one or more but less than all of the series of Bonds then outstanding under the Indenture are so affected. No modification or alteration shall be made which will affect the terms of payment of the principal of or premium, if any, or interest on, this Bond, which are unconditional. The Company has reserved the right to make certain amendments to the Indenture, without any consent or other action by holders of the Bonds of this series to the extent necessary from time to time to qualify the Indenture under the Trust Indenture Act of 1939 and to make certain other amendments, all as more fully provided in the Indenture and in the Supplemental Indenture.

This Bond is subject to redemption by the Company, prior to December 15, 2034 (the “Par Call Date”) at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimals) equal to the greater of: (1)(a) the sum of present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the bonds matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate applicable to the Bond plus 15 basis points less (b) interest accrued to the redemption date; and (2) 100% of the principal amount of the Bond to be redeemed, plus in either case, accrued and unpaid interest thereon to, but excluding, the redemption date.

This Bond is subject to redemption by the Company on or after Par Call Date at its option, in whole or in part, at any time and from time to time in part, at a redemption price equal to 100% of the principal amount of the Bond to be redeemed, plus accrued and unpaid interest thereon, but excluding, the redemption date.

For purposes of the optional redemption provisions, the following term has the following meaning:

“Treasury Rate” means, with respect to any redemption date, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities—Treasury constant maturities — Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable:

•

the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date (the “Remaining Life”); or

•

if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or

•

if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this clause, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date. If there is no United States Treasury security maturing on the Par Call Date, but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date, or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury

securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

The Trustee shall have no obligation or duty whatsoever to determine, or to verify the Company’s calculations of, the redemption price.

Such redemption in every case shall be effected upon notice given: (1) at least ten days and not more than sixty days prior to the redemption date, to the registered owners of such Bonds at their addresses as the same shall appear on the transfer register of the Company; and (2) stating, among other things, the redemption price (or if not then ascertainable, the manner of calculation thereof) and date, in each case, subject to the conditions of and as more fully set forth in the Indenture. If less than all of the outstanding Bonds are to be redeemed, the Bonds to be redeemed shall be selected in accordance with the policies and procedures of The Depository Trust Company (or any successor depositary thereto), provided that in the event the Bonds are no longer held in the global form, the Bonds to be redeemed shall be selected by the Trustee by lot.

Notwithstanding the foregoing, so long as there is no existing default in the payment on the Bonds of the 5.25% Series due 2035, installments of interest on the Bonds of the 5.25% Series due 2035 that are due and payable on an interest payment date falling on or prior to a redemption date shall be payable on such interest payment date to the registered owners of the Bonds of the 5.25% Series due 2035 as of the close of business on the relevant record date according to the Bonds of the 5.25% Series due 2035 and the Indenture, except as and to the extent the Company shall default in the payment of the interest due on such interest payment date, in which case defaulted interest shall be paid to the person in whose name such Bond of the 5.25% Series due 2035 is registered on the date of payment of such defaulted interest. The redemption price will be calculated assuming a 360-day year consisting of twelve 30-day months.

A notice of redemption may provide that the optional redemption described in such notice is conditioned upon the occurrence of certain events before the redemption date. Such notice of conditional redemption will be of no effect unless all such conditions to the redemption have occurred before the redemption date or have been waived by the Company. If any of these events fail to occur and are not waived by the Company, the Company will be under no obligation to redeem the Bonds or pay the holders thereof any redemption proceeds, and the Company’s failure to so redeem the Bonds will not be considered a default or event of default under the Indenture. In the event that any of these conditions fail to occur and are not waived by the Company, the Company will promptly notify the Trustee in writing that the conditions precedent to such redemption have failed to occur and the Bonds will not be redeemed.

Unless the Company defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the Bonds or portions of the Bonds called for redemption.

In case an event of default, as defined in the Indenture, shall occur, the principal of all of the Bonds at any such time outstanding under the Indenture may be declared or may become due and payable, upon the conditions and in the manner and with the effect provided in the Indenture. The Indenture provides that such declaration may in certain events be waived by the holders of a majority in principal amount of the Bonds outstanding.

This Bond is transferable by the registered owner hereof, in person or by duly authorized attorney, on the books of the Company to be kept for that purpose at the agency of the Company in the City of Chicago, Illinois, and at the agency of the Company in the Borough of Manhattan, The City of New York, upon surrender and cancellation of this Bond and on presentation of a duly executed written instrument of transfer, and thereupon a new registered Bond or Bonds of the same series, of the same aggregate principal amount and in authorized denominations will be issued to the transferee or transferees in exchange herefor; and this Bond, with or without others of like form and series, may in like manner be exchanged for one or more new registered Bonds of the same series of other authorized denominations but of the same aggregate principal amount; all upon payment of the charges and subject to the terms and conditions set forth in the Indenture.

The Company or a successor entity may deliver to the Trustee in substitution for any Bonds of the 5.25% Series due 2035, mortgage bonds or other similar instruments as set forth in the Indenture.

Subject to the preceding sentence, no recourse shall be had for the payment of the principal of or premium, if any, or interest on this Bond, or for any claim based hereon or on the Indenture or any indenture supplemental thereto, against any incorporator, or against any stockholder, director or officer, past, present or future, of the Company, or of any predecessor or successor corporation, as such, either directly or through the Company or any such 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 otherwise, all such liability, whether at common law, in equity, by any constitution, statute or otherwise, of incorporators, stockholders, directors or officers being released by every owner hereof by the acceptance of this Bond and as part of the consideration for the issue hereof, and being likewise released by the terms of the Indenture.

No director, officer, employee or stockholder of the Company will have any liability for any obligations of the Company under the Bonds or Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder by accepting a Bond waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Bonds. The waiver may not be effective to waive liabilities under the federal securities laws. It is the view of the Securities and Exchange Commission that this type of waiver is against public policy.

This Bond shall not be entitled to any benefit under the Indenture or any indenture supplemental thereto, or become valid or obligatory for any purpose, until The Bank of New York Mellon Trust Company, N.A., the Trustee (as successor to Harris Trust and Savings Bank) under the Indenture, or a successor trustee thereto under the Indenture, shall have signed the form of certificate endorsed hereon.

IN WITNESS WHEREOF, EVERGY KANSAS CENTRAL, INC. has caused this Bond to be signed in its name by its Chairman of the Board, President and Chief Executive Officer or a Vice President, manually or electronically, and its corporate seal (or a facsimile thereof) to be hereto affixed and attested by its Secretary or an Assistant Secretary, manually or electronically.

The Trustee shall have the right to accept and act upon instructions (“Instructions”), including fund transfer instructions given pursuant to this Supplemental Indenture and delivered using Electronic Means; provided, however, that the Company shall provide to the Trustee an incumbency certificate listing officers and other Company personnel with the authority to provide such Instructions (“Authorized Officers”) and containing specimen signatures of such Authorized Officers, which incumbency certificate shall be amended by the Company whenever a person is to be added or deleted from the listing or promptly upon reasonable request of the Trustee. If the Company elects to give the Trustee Instructions using Electronic Means and the Trustee in its reasonable discretion elects to act upon such Instructions, the Trustee’s reasonable understanding of such Instructions shall be deemed controlling. The Company understands and agrees

that the Trustee shall be entitled to presume that directions that purport to have been sent by an Authorized Officer listed on the incumbency certificate provided to the Trustee have been sent by such Authorized Officer. The Company shall establish reasonable procedures to ensure that only Authorized Officers transmit such Instructions to the Trustee and that the Company and all Authorized Officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt by the Company. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such Instructions notwithstanding such directions conflict or are inconsistent with a subsequent written instruction. The Company agrees: (i) to assume all risks arising out of the use of the Electronic Means it selects to submit Instructions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized Instructions, and the risk of interception and misuse by third parties; (ii) that it is informed of the protections and risks associated with the various methods of transmitting Instructions to the Trustee and that there may be more secure methods of transmitting Instructions than the method(s) selected by the Company; (iii) that the security procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances; and (iv) to notify the Trustee immediately upon learning of any compromise or unauthorized use of the security procedures. For purposes of this Section 7, “Electronic Means” shall mean the following communications methods: e-mail, secure electronic transmission containing applicable authorization codes, passwords and/or authentication keys issued by the Trustee, or another method or system specified by the Trustee as available for use in connection with its services hereunder.

Section 8. OFAC Compliance. With respect to the Bonds of the 5.25% Series due 2035:

(a) The Company covenants and represents that neither it nor, to the knowledge of the Company, any of its affiliates, subsidiaries, directors or officers are the target or subject of any sanctions enforced by the US Government (including the Office of Foreign Assets Control of the US Department of the Treasury (“OFAC”)), the United Nations Security Council, the European Union, His Majesty’s Treasury, or other relevant sanctions authority (collectively, “Sanctions”).

(b) The Company covenants and represents that neither it nor any of its affiliates, subsidiaries, directors or officers will use any part of the proceeds received in connection with the Indenture or any other of the transaction documents (i) to fund or facilitate any activities of or business with any person who, at the time of such funding or facilitation, is the subject or target of Sanctions, (ii) to fund or facilitate any activities of or business with any country or territory that is the target or subject of Sanctions, or (iii) in any other manner that will result in a violation of Sanctions by any person.

Section 9. FATCA. In order to comply with applicable tax laws, rules and regulations (inclusive of directives, guidelines and interpretations promulgated by competent authorities) in effect from time to time (“Applicable Law”) that a foreign financial institution, issuer, trustee, paying agent, holder or other institution is or has agreed to be subject to related to this Supplemental Indenture, the Company agrees (i) to provide to the Trustee sufficient information about holders or other applicable parties and/or transactions (including any modification to the terms of such transactions) so the Trustee can determine whether it has tax related obligations under Applicable Law, (ii) that the Trustee shall be entitled to make any withholding or deduction from payments under the Indenture to the extent necessary to comply with Applicable Law for which the Trustee shall not have any liability, and (iii) to hold harmless the Trustee for any losses it may suffer due to the actions it takes to comply with such Applicable Law.
