Such interest shall be payable semiannually in arrears, on May 15 and November 15 of each year (each such date, an "Interest Payment Date"), commencing May 15, 2006.

succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay) with the same force and effect as if made on the date the payment was originally payable.

(d) Any principal and premium, if any, and any installment of interest, which is overdue shall bear interest at the rate of 6.05% per annum (to the extent permitted by law), from the dates such amounts are due until they are paid or made available for payment, and such interest shall be payable on demand.

KANSAS CITY POWER & LIGHT COMPANY, a Missouri corporation (hereinafter called the "Company", which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to the registered holder named above or registered assigns, on the maturity date stated above, the principal sum stated above and to pay interest thereon from November 17, 2005, or from the most recent interest payment date to which interest has been duly paid or provided for, initially on May 15, 2006, and thereafter semi-annually on May 15 and November 15 of each year, at the interest rate stated above, until the date on which payment of such principal sum has been made or duly provided for. The interest so payable on any interest payment date will be paid to the person in whose name this Security is

registered at the close of business on the May 1 or November 1, as the case may be, immediately preceding that interest payment date, except as otherwise provided in the Indenture.

The principal and interest payments on the Security will be made by the Company to DTC for disbursement to the registered holder named above. All such payments shall be made in such coin or currency of the United States of America as at the time of payment is legally tender for payment of public and private debts.

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, dated as of March 1, 2002 (herein called the "Indenture", which term shall have the meaning assigned to it in such instrument), between the Company and The Bank of New York, as Trustee (herein called the "Trustee", which term includes any successor trustee under the Indenture). Reference is made to the Indenture and any supplemental indenture thereto for the provisions relating, among other things, to the respective rights of the Company, the Trustee and the holders of the Securities, and the terms on which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, initially limited in aggregate principal amount to $250,000,000; provided, however, that the authorized aggregate principal amount of the Securities may be increased above such amount by a Board Resolution to such effect.

The Company shall have the right to redeem the Securities of this series, in whole or in part, at its option at any time from time to time at a price equal to the greater of (i) 100% of the principal amount thereof or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities to be redeemed (not including any portion of such payments of interest accrued to the date of redemption) discounted to the date of redemption on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable treasury rate plus 25 basis points, plus, in each case, accrued and unpaid interest on the principal amount of the Securities being redeemed to the redemption date. The treasury rate will be calculated on the third business day preceding the date fixed for redemption.

For purposes of determining the redemption price:

"treasury rate", means, with respect to any redemption date: (i) 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 U.S. 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 life (as defined below), yields for the two published maturities most closely corresponding to the comparable treasury issue will be determined and the treasury rate will be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month); or (ii) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semiannual 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;

"comparable treasury issue" means the U.S. Treasury security selected by an independent investment banker as having a maturity comparable to the remaining term ("remaining life") of the Securities to be redeemed 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 the remaining term of such Securities;

If an Event of Default (as defined in the Indenture) shall have occurred and be continuing with respect to the Securities, the principal hereof may be declared, and upon such declaration shall become due and payable, in the manner, with such effect and subject to the conditions provided in the Indenture. Any such declaration may be rescinded by holders of a majority in principal amount of the outstanding Securities if all Events of Default with respect to the

Securities (other than the non-payment of principal of the Securities which shall have become due by such declaration) shall have been remedied.

The Indenture contains provisions permitting the Company and the Trustee, with the consent of the holders of not less than a majority in aggregate principal amount of the Securities at the time outstanding, evidenced as in the Indenture provided, to execute supplemental indentures adding any provisions to the Indenture or to any supplemental indenture with respect to the Securities, or modifying in any manner the rights of the holders of the Securities; provided, however, that no such supplemental indenture shall (i) extend the fixed maturity of any Securities or reduce the principal amount thereof, or reduce the rate thereon, or make the principal thereof, or interest thereon, payable in any coin or currency other than that in the Securities provided, without the consent of each holder of the Securities so affected, or (ii) reduce the aforesaid principal amount of the Securities, the holders of which are required to consent to any such supplemental indenture without the consent of the holders of all Securities then outstanding. The Indenture also contains provisions permitting the holders of not less than a majority in aggregate principal amount of the Securities at the time outstanding, evidenced as in the Indenture provided, to waive certain past defaults under the Indenture and their consequences.

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 premium, if any) and interest on this Security at the times, place and rate, and in the coin or currency, herein provided.

This Security is issuable as a registered Security only, in the denomination of $1,000 and any integral multiples of $1,000 approved by the Company, such approval to be evidenced by the execution thereof.

As provided in the Indenture and the Supplemental Indenture No. 1, dated as of November 15, 2005 (herein called "Supplemental Indenture No. 1") and subject to certain limitations therein set forth, this Security is transferable by the registered holder hereof in person or by his attorney duly authorized in writing on the books of the Company at the office or agency to be maintained by the Company for that purpose, but only in the manner, subject to the limitations and upon payment of any tax or governmental charge for which the Company may require reimbursement as provided in the Indenture, and upon surrender and cancellation of this Security. Upon any registration of transfer, a new registered Security or Securities, of authorized denomination or denominations, and in the same aggregate principal amount, will be issued to the transferee in exchange therefore.

The Company, the Trustee, any paying agent and any Security Registrar may deem and treat the registered holder hereof as the absolute owner of this Security (whether or not this Security shall be overdue and notwithstanding any notations of ownership or other writing hereof made by anyone other than the Security Registrar) for the purpose of receiving payment of or on account of the principal hereof and interest due hereon as herein provided and for all other purposes, and neither the Company nor the Trustee nor any paying agent nor any Security Registrar shall be affected by any notice to the contrary.

No recourse shall be had for the payment of the principal of or interest on this Security, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator or against any past, present or future stockholder, officer or member of the Board of Directors, as such, of the Company, whether by virtue of any constitution, state or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as party of the consideration for the issue hereof, expressly waived and released.

By its acceptance of this Security bearing a legend restricting transfer, each holder of this Security acknowledges the restrictions on transfer of this Security set forth in the Indenture, Supplemental Indenture No. 1 and such legend and agrees that it will transfer this Security only as provided in the Indenture and Supplemental Indenture No. 1. In addition to the rights provided to holders of this Security under the Indenture, holders shall have all the rights set forth in that certain Registration Rights Agreement, dated November 17, 2005, among the Company and the Initial Purchasers, including without limitation the right to receive Additional Interest as described in Section 6 thereof. This Security and all 6.05% Senior Notes due 2035 Series A and 6.05% Senior Notes due 2035 Series B from time to time issued and outstanding under the Indenture (collectively, the "2035 Securities") will vote and consent together on all matters as one class and none of the 2035 Securities will have the right to vote or consent as a class separate from one another on any matter.

This Security shall be deemed to be a contract made under the laws of the State of New York, and for all purposes shall be construed in accordance with the laws of the State of New York.

All terms used in this Security which are defined in the Indenture and Supplemental Indenture No. 1 and not defined herein shall have the meaning assigned to them in the Indenture and Supplemental Indenture No. 1.

This Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose until the certificate of authentication on the face hereof is manually signed by the Trustee.

This Note has not been registered under the Securities Act of 1933, as amended (the "Securities Act"), or under the securities laws of any state or other jurisdiction, and this Note may not be offered, sold, pledged or otherwise transferred except pursuant to an effective registration statement or in accordance with an applicable exemption from the registration requirements of the Securities Act (subject to the delivery of such evidence, if any, required under the indenture pursuant to which this Note is issued) and in accordance with any applicable securities laws of any state of the United States or any other jurisdiction. Each purchaser of this Note is hereby notified that the seller may be relying on the exemption from the provisions of Section 5 of the Securities Act provided by Rule 144A thereunder or another exemption under the Securities Act. The holder of this Note agrees for the benefit of Kansas City Power & Light Company that (a) prior to the date which is two years after the later of the date of original issuance of this Note and the last

date on which Kansas City Power & Light Company or any of its affiliates was the owner of this Note (or any predecessor of this Note) or such shorter period as may be prescribed by Rule 144(k), or any successor provision thereof, under the Securities Act (the "Resale Restriction Termination Date"), this Note may be resold, pledged or otherwise transferred only (1) (A) for so long as the Note is eligible for resale pursuant to Rule 144A, to a person who the seller reasonably believes is a Qualified Institutional Buyer (as defined in Rule 144A under the Securities Act) in a transaction meeting the requirements of Rule 144A, (B) in an offshore transaction complying with Rule 903 or Rule 904 of Regulation S under the Securities Act, (C) in a transaction meeting the requirements of Rule 144 under the Securities Act, (D) in accordance with another exemption from the registration requirements of the Securities Act as long as, prior to any offer, sale or transfer of this Note the registrar receives a certification of the transferor and, if required by the Company or the Trustee in the case of (B), (C) or (D) above, an opinion of counsel that such transfer is in compliance with the Securities Act, (2) to Kansas City Power & Light Company or (3) pursuant to an effective registration statement and, in each case, in accordance with any applicable securities laws of any state of the United States or any other applicable jurisdiction and (b) the holder will and each subsequent holder is required to notify any purchaser from it of this Note of the resale restriction set forth in (a) above. This legend will be removed upon the request of the holder after the Resale Restriction Termination Date or such earlier time as determined by Kansas City Power & Light Company in accordance with applicable law.
