 The principal and
interest payments on this Note will be made by the Company 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 Note is one of a duly authorized issue of notes of the Company (herein called the “Notes”),
issued under an Indenture, dated as of May 1, 2007, as previously supplemented and further supplemented by Supplemental Indenture No. 3, dated as of September 20, 2011, as amended by Supplemental Indenture No. 8 dated as of
March 1, 2019 (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 Mellon Trust Company, N.A. (formerly The Bank of New York Trust
Company, N.A.), 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 Notes, and the terms on which the Notes are authenticated and delivered. This Note is one of the series designated on the face hereof, initially limited in
aggregate principal amount to $400,000,000; provided, however, that the authorized aggregate principal amount of the Notes may be increased above such amount by a Board Resolution authorizing such increase. 

The Notes will be secured by a series of mortgage bonds (the “2041 Collateral Mortgage Bonds”) delivered by the Company to
the Trustee for the benefit of the Holders of the Notes, issued pursuant to the Sixteenth Supplemental Indenture, dated as of March 1, 2019 to the General Mortgage Indenture and Deed of Trust, dated as of December 1, 1986, between the
Company and UMB Bank, N.A. (formerly United Missouri Bank of Kansas City, N.A.) (as amended and supplemented, the “Mortgage Indenture”). Reference is made to the Indenture and the Mortgage Indenture for a description of the rights
of the Trustee as holder of the 2041 Collateral Mortgage Bonds, the property mortgaged and pledged, the nature and extent of the security and rights of the holders of the mortgage bonds under the Mortgage Indenture and the rights of the Company
under the Mortgage Indenture and the terms and conditions upon which the Notes are secured. 
 Prior to April 1, 2041, the Company
shall have the right to redeem the Notes of this series, at its option, at any time in whole, or from time to time in part, at a redemption price equal to the greater of (i) 100% of the principal amount to be redeemed and (ii) the sum of the
present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed (not including any portion of such payments of interest accrued as of the date of redemption), discounted to the date of redemption on a
semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 30 basis points; plus, in each case, accrued and unpaid interest
on the principal amount of the Notes being redeemed to the redemption date. 

  
 A-2 













 On or after April 1, 2041, the Company shall have the right to redeem the 2041 Notes,
at its option, at any time in whole, or from time to time in part, at a redemption price equal to 100% of the principal amount of the 2041 Notes to be redeemed, plus accrued and unpaid interest on the principal amount being redeemed to the
redemption date. 
 For purposes of determining the redemption price: 

“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity
comparable to the remaining term of the Notes 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 the Notes. 
 “Comparable Treasury Price” means, with respect to any redemption date, (1) the
average of four Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (2) if the Quotation Agent obtains fewer than four such Reference Treasury
Dealer Quotations, the average of all such quotations, or (3) if only one such Reference Treasury Dealer Quotation is received, such quotation. 

“Quotation Agent” means a Reference Treasury Dealer appointed by the Company. 

“Reference Treasury Dealer” means (1) each of Barclays Capital Inc. and RBS Securities Inc. or their affiliates, and
their respective successors, unless either of them ceases to be a primary U.S. government securities dealer in the United States of America (“Primary Treasury Dealer”), in which case the Company will substitute therefore another Primary
Treasury Dealer, (2) a Primary Treasury Dealer selected by Wells Fargo Securities, LLC and (3) two other Primary Treasury Dealers selected by the Company. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the
average, as determined by the Quotation Agent, 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 Quotation Agent by such Reference Treasury Dealer
at 5:00 p.m., New York City time, on the third business day preceding such redemption date. 
 “Treasury Rate” means, with
respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming 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 Indenture contains provisions for defeasance at any time of (i) the
entire indebtedness of this Note and (ii) the Company’s obligations under the Indenture and this Note with respect to certain covenants and related Events of Default, upon compliance by the Company with certain conditions set forth in the
Indenture. 

  
 A-3 













 If an Event of Default with respect to the Notes shall occur and be continuing, the
principal of this Note may be declared due and payable in the manner and with the effect provided in the Indenture. 
 The Indenture
permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the securities of each series to be affected under the Indenture at any
time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the securities at the time outstanding of all series to be affected, considered as one class. The Indenture contains provisions
permitting the Holders of a majority in aggregate principal amount of the securities of any series at the time outstanding, on behalf of the Holders of all securities of such series, to waive certain past defaults or Events of Default under the
Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued in exchange, substitution or upon the
registration or transfer hereof, irrespective of whether or not notation of such consent or waiver is made upon this Note. 
 No reference
herein to the Indenture and no provision of this Note 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 Note at the times,
place and rate, and in the coin or currency, herein provided. 
 This Note is issuable as a registered Note only, in the minimum
denomination of $2,000 and integral multiples of $1,000. 
 As provided in the Indenture, this Note 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. Upon any registration of transfer, a new registered Note or Notes, 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 Authenticating Agent may deem and treat the registered Holder hereof as the absolute owner of this Note (whether or not this Note shall be overdue) for the purpose of receiving payment of or on account
of the principal and premium, if any, and interest on this Note as herein provided and for all other purposes, and neither the Company nor the Trustee nor any paying agent nor any Authenticating Agent shall be affected by any notice to the contrary.

 No recourse shall be had for the payment of the principal of or any premium or interest on this Note, 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

whose name this Note is registered at the close of business on the March 1 or September 1, as the case may be (whether or not such day is a Business Day), immediately preceding that Interest Payment Date, except as otherwise provided in
the Indenture. 
 The principal and interest payments on this Note will be made by the Company 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 Note is one of a duly authorized issue of notes of the Company (herein called the “Notes”), issued under an Indenture,
dated as of May 1, 2007, as previously supplemented and further supplemented by Supplemental Indenture No. 4, dated as of March 14, 2013, as amended by Supplemental Indenture No. 8 dated as of March 1, 2019 (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 Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), 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 Notes, and the terms on which the Notes are authenticated and delivered. This Note is one of the series designated on the face hereof, initially limited in aggregate principal amount to
$300,000,000; provided, however, that the authorized aggregate principal amount of the Notes may be increased above such amount by a Board Resolution authorizing such increase. 

The Notes will be secured by a series of mortgage bonds (the “2023 Collateral Mortgage Bonds”) delivered by the Company to
the Trustee for the benefit of the Holders of the Notes, issued pursuant to the Sixteenth Supplemental Indenture, dated as of March 1, 2019 to the General Mortgage Indenture and Deed of Trust, dated as of December 1, 1986, between the
Company and UMB Bank, N.A. (formerly United Missouri Bank of Kansas City, N.A.) (as amended and supplemented, the “Mortgage Indenture”). Reference is made to the Indenture and the Mortgage Indenture for a description of the rights
of the Trustee as holder of the 2023 Collateral Mortgage Bonds, the property mortgaged and pledged, the nature and extent of the security and rights of the holders of the mortgage bonds under the Mortgage Indenture and the rights of the Company
under the Mortgage Indenture and the terms and conditions upon which the Notes are secured. 
 Prior to December 15, 2022, the Company
shall have the right to redeem the Notes of this series, at its option, at any time in whole, or from time to time in part, at a redemption price equal to the greater of (i) 100% of the principal amount to be redeemed and (ii) the sum of the
present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed (not including any portion of such payments of interest accrued as of the date of redemption), discounted to the date of redemption on a
semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 20 basis points; plus, in each case, accrued and unpaid interest
on the principal amount of the Notes being redeemed to the redemption date. 

  
 B-2 













 On or after December 15, 2022, the Company shall have the right to redeem the Notes, at
its option, at any time in whole, or from time to time in part, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest on the principal amount being redeemed to the redemption date.

 For purposes of determining the redemption price: 

“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity
comparable to the remaining term of the Notes 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 the Notes. 
 “Comparable Treasury Price” means, with respect to any redemption date, (1) the
average of four Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (2) if the Quotation Agent obtains fewer than four such Reference Treasury
Dealer Quotations, the average of all such quotations, or (3) if only one such Reference Treasury Dealer Quotation is received, such quotation. 

“Quotation Agent” means a Reference Treasury Dealer appointed by the Company. 

“Reference Treasury Dealer” means (1) each of BNP Paribas Securities Corp. and Merrill Lynch, Pierce, Fenner &
Smith Incorporated or their affiliates, and their respective successors, unless either of them ceases to be a primary U.S. government securities dealer in the United States of America (“Primary Treasury Dealer”), in which case the Company
will substitute therefor another Primary Treasury Dealer, (2) a Primary Treasury Dealer selected by Mitsubishi UFJ Securities (USA), Inc. and (3) two other Primary Treasury Dealers selected by the Company. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the
average, as determined by the Quotation Agent, 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 Quotation Agent by such Reference Treasury Dealer
at 5:00 p.m., New York City time, on the third business day preceding such redemption date. 
 “Treasury Rate” means, with
respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming 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 Indenture contains provisions for defeasance at any time of (i) the
entire indebtedness of this Note and (ii) the Company’s obligations under the Indenture and this Note with respect to certain covenants and related Events of Default, upon compliance by the Company with certain conditions set forth in the
Indenture. 

  
 B-3 













 If an Event of Default with respect to the Notes shall occur and be continuing, the
principal of this Note may be declared due and payable in the manner and with the effect provided in the Indenture. 
 The Indenture
permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the securities of each series to be affected under the Indenture at any
time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the securities at the time outstanding of all series to be affected, considered as one class. The Indenture contains provisions
permitting the Holders of a majority in aggregate principal amount of the securities of any series at the time outstanding, on behalf of the Holders of all securities of such series, to waive certain past defaults or Events of Default under the
Indenture, and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued in exchange, substitution or upon the
registration or transfer hereof, irrespective of whether or not notation of such consent or waiver is made upon this Note. 
 No reference
herein to the Indenture and no provision of this Note 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 Note at the times,
place and rate, and in the coin or currency, herein provided. 
 This Note is issuable as a registered Note only, in the minimum
denomination of $2,000 and integral multiples of $1,000. 
 As provided in the Indenture, this Note 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. Upon any registration of transfer, a new registered Note or Notes, 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 Authenticating Agent may deem and treat the registered Holder hereof as the absolute owner of this Note (whether or not this Note shall be overdue) for the purpose of receiving payment of or on account
of the principal and premium, if any, and interest on this Note as herein provided and for all other purposes, and neither the Company nor the Trustee nor any paying agent nor any Authenticating Agent shall be affected by any notice to the contrary.

 No recourse shall be had for the payment of the principal of or any premium or interest on this Note, 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 part of the consideration for the issue hereof,
expressly waived and released.

 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 June 15, 2017, or from the most recent Interest Payment Date to which interest has been duly paid or provided for, initially on December 15, 2017, and thereafter
semi-annually on June 15 and December 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 Note is registered at the close of business on the fifteenth calendar day prior to such Interest Payment Date (whether or not such day is a Business Day), except as otherwise provided in the Indenture. 

The principal and interest payments on this Note will be made by the Company 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 Note is one of a duly authorized issue of notes of the Company (herein called the “Notes”), issued under an Indenture,
dated as of May 1, 2007, as previously supplemented and further supplemented by Supplemental Indenture No. 6, dated as of June 15, 2017, as amended by Supplemental Indenture No. 8 dated as of March 1, 2019 (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 Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), 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 Notes, and the terms on which the Notes are authenticated and delivered. This Note is one of the series designated on the face hereof, initially limited in aggregate principal amount to
$300,000,000; provided, however, that the authorized aggregate principal amount of the Notes may be increased above such amount by a Board Resolution authorizing such increase. Any additional notes issued pursuant to such increase must rank
equally and ratably with, and have the same interest rate, maturity and other terms (except for the price to public, the Original Issue Date and the first Interest Payment Date, as applicable) as, the Notes. Any additional notes, together with the
Notes, will constitute a single series of notes under the Indenture; provided that if any such additional notes are not fungible for U.S. federal income tax purposes with the Notes, such additional notes will be issued under a separate CUSIP number.

 The Notes will be secured by a series of mortgage bonds (the “2047 Collateral Mortgage Bonds”) delivered by the Company
to the Trustee for the benefit of the Holders of the Notes, issued pursuant to the Sixteenth Supplemental Indenture, dated as of March 1, 2019 to the General Mortgage Indenture and Deed of Trust, dated as of December 1, 1986, between the
Company and UMB Bank, N.A. (formerly United Missouri Bank of Kansas City, N.A.) (as amended and supplemented, the “Mortgage Indenture”). Reference is made to the Indenture and the Mortgage Indenture for a description of the rights
of the Trustee as holder of the 2047 Collateral Mortgage Bonds, the property mortgaged and pledged, the nature and extent of the security and rights of the holders of the mortgage bonds under the Mortgage Indenture and the rights of the Company
under the Mortgage Indenture and the terms and conditions upon which the Notes are secured.

its option, at any time in whole, or from time to time in part, at a redemption price equal to the greater of (i) 100% of the principal amount of the 2047 Notes being redeemed and (ii) the sum of the present values of the remaining scheduled
payments of principal and interest on the 2047 Notes being redeemed that would be due if the 2047 Notes matured on the Par Call Date (not including any portion of such payments of interest accrued as of the date of redemption), discounted to the
date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate, plus 20 basis points; plus, in each case,
accrued and unpaid interest on the principal amount of the 2047 Notes being redeemed to, but excluding, the redemption date. 
 On or after
the Par Call Date, the Company shall have the right to redeem the 2047 Notes, at its option, at any time in whole, or from time to time in part, at a redemption price equal to 100% of the principal amount of the 2047 Notes being redeemed, plus
accrued and unpaid interest on the principal amount of the 2047 Notes being redeemed to, but excluding, the redemption date. 
 For purposes
of determining the redemption price: 
 “Comparable Treasury Issue” means the United States Treasury security selected by
the Quotation Agent as having a maturity comparable to the remaining term of the Notes to be redeemed (assuming, for this purpose, that the Notes matured on the Par Call Date) 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 the Notes. 

“Comparable Treasury Price” means, with respect to any redemption date, (1) the average of the Reference Treasury Dealer
Quotations for such redemption date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, (2) if the Quotation Agent obtains fewer than four of such Reference Treasury Dealer Quotations, the average of all such
Reference Treasury Dealer Quotations, or (3) if only one such Reference Treasury Dealer Quotation is received, such Reference Treasury Dealer Quotation. 

“Par Call Date” means December 15, 2046. 

“Quotation Agent” means a Reference Treasury Dealer appointed by the Company. 

“Reference Treasury Dealer” means (1) BNP Paribas Securities Corp. or its affiliates and successors, unless it ceases to

by SunTrust Robinson Humphrey, Inc., and (3) three other Primary Treasury Dealers selected by the Company.

the Quotation Agent by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such redemption date. 

“Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to
maturity of the Comparable Treasury Issue, assuming 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 Indenture contains provisions for defeasance at any time of (i) the entire indebtedness of this Note and (ii) the Company’s
obligations under the Indenture and this Note with respect to certain covenants and related Events of Default, upon compliance by the Company with certain conditions set forth in the Indenture. 

If an Event of Default with respect to the Notes shall occur and be continuing, the principal of this Note may be declared due and payable in
the manner and with the effect provided in the Indenture. 
 The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the
Holders of a majority in aggregate principal amount of the securities at the time outstanding of all series to be affected, considered as one class. The Indenture contains provisions permitting the Holders of a majority in aggregate principal amount
of the securities of any series at the time outstanding, on behalf of the Holders of all securities of such series, to waive certain past defaults or Events of Default under the Indenture, and their consequences. Any such consent or waiver by the
Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued in exchange, substitution or upon the registration or transfer hereof, irrespective of whether or not notation of
such consent or waiver is made upon this Note. 
 No reference herein to the Indenture and no provision of this Note 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 Note at the times, place and rate, and in the coin or currency, herein provided. 

This Note is issuable as a registered Note only, in the minimum denomination of $2,000 and integral multiples of $1,000 in excess thereof.

 As provided in the Indenture, this Note 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. Upon any registration of transfer, a new registered Note or Notes, of authorized denomination or denominations, and in the same aggregate
principal amount, will be issued to the transferee in exchange therefor.

 The Company, the Trustee, any paying agent and any Authenticating Agent may deem and treat
the registered Holder hereof as the absolute owner of this Note (whether or not this Note shall be overdue) for the purpose of receiving payment of or on account of the principal of (and premium, if any) and interest on this Note as herein provided
and for all other purposes, and neither the Company nor the Trustee nor any paying agent nor any Authenticating Agent shall be affected by any notice to the contrary. 

No recourse shall be had for the payment of the principal of or any premium or interest on this Note, 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 part of the consideration for the issue hereof,
expressly waived and released. 
 This Note shall be governed by and deemed to be a contract made under, and construed in accordance with,
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 without regard to conflicts of law principles thereof. 

All terms used in this Note which are defined in the Indenture and not defined herein shall have the meaning assigned to them in the
