DESCRIPTION OF THE REGISTRANT’S SECURITIES
REGISTERED

 PURSUANT TO SECTION 12 OF THE SECURITIES EXCHANGE ACT OF 1934

 

HealthLynked Corp. (the “Company”)
has one class of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended: the Company’s common
stock, par value $0.0001 per share (the “Common Stock”).

 

Description of Common Stock

 

The following summary description sets forth some
of the general terms and provisions of the Common Stock. Because this is a summary description, it does not contain all of the information
that may be important to you. For a more detailed description of the Company’s Common Stock, you should refer to the provisions
of the Company’s Articles of Incorporation, as amended (the “Articles of Incorporation”) and the Company’s Bylaws,
as amended (the “Bylaws”), each of which is an exhibit to the Annual Report on Form 10-K to which this description is an exhibit.

 

Authorized Shares

 

We are authorized to issue 500,000,000 shares
of common stock, par value $0.0001 per share.

 

Voting Rights

 

The holders of common stock are entitled to one
vote per share for the election of directors and with respect to all other matters submitted to a vote of stockholders. Shares of our
common stock do not have cumulative voting rights, which means that the holders of more than 50% of such shares voting for the election
of directors can elect 100% of the directors if they choose to do so. Our common stock does not have preemptive rights, meaning that the
common stockholders’ ownership interest in the Company would be diluted if additional shares of common stock are subsequently issued
and the existing stockholders are not granted the right, at the discretion of the Board of Directors, to maintain their ownership interest
in our Company.

 

Liquidation, Dissolution or Similar Rights

 

Upon liquidation, dissolution or winding-up of
the Company, our assets, after the payment of debts and liabilities and any liquidation preferences of, and unpaid dividends on, any class
of preferred stock then outstanding, will be distributed pro-rata to the holders of our common stock.

 

Preemptive Rights

 

The holders of our common stock do not have preemptive
rights, meaning that the common stockholders’ ownership interest in the Company would be diluted if additional shares of common
stock are subsequently issued and the existing stockholders are not granted the right, at the discretion of the Board of Directors, to
maintain their ownership interest in our Company.

 

Dividend Rights

 

The holders of common stock are entitled to share
equally in dividends, if, as and when declared by our Board of Directors, out of funds legally available therefore, subject to the priorities
given to any class of preferred stock which may be issued.

 

Transfer Agent

 

The Company’s transfer agent is Worldwide
Stock Transfer. The transfer agent’s telephone number is (201) 820-2008.

 

    

     

    

 

Indemnification Of Directors And Executive
Officers And Limitation On Liability

 

The Company’s Bylaws provide that no director
or officer of the Company shall be personally liable to the Company or any of its stockholders for damages for breach of fiduciary duty
as a director or officer of for any act or omission of any such director or officer; however such indemnification shall not eliminate
or limit the liability of a director or officer for (a) acts or omissions which involve intentional misconduct, fraud or a knowing violation
of law or (b) the payment of dividends in violation of Section 78.300 of the Nevada Revised Statutes.

 

The Company’s Articles of Incorporation
provide that any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit
or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that such person is or was a director or
officer of the Company (or is or was serving at the request of the Company as a director, officer, or representative of another corporation,
partnership, joint venture, trust or other enterprise) shall be indemnified and held harmless by the Company to the fullest extent permitted
by Nevada law against expenses including attorneys’ fees, judgments, fines and amounts paid in settlement actually and reasonably
incurred by such person in connection with such proceeding.

 

The Articles of Incorporation also provide that
the expenses of officers and directors incurred in defending a civil or criminal action, suit or proceeding must be paid by the Company
as they are incurred and in advance of the final disposition of the action, suit or proceeding, upon receipt of an undertaking by or on
behalf of the director or officer to repay the amount if it is ultimately determined by a court of competent jurisdiction that he is not
entitled to be indemnified by the Company.

 

The Articles of Incorporation provide that the
Company may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the Company,
or is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise in accordance with the laws of the State of Nevada.

 

Nevada Revised Statutes 78.751 and 78.7502 have
provisions that provide for discretionary and mandatory indemnification of officers, directors, employees, and agents of a corporation.
Under these provisions, such persons may be indemnified by a corporation against expenses, including attorney’s fees, judgment,
fines and amounts paid in settlement, actually and reasonably incurred by him in connection with the action, suit or proceeding, if he
acted in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the corporation and
with respect to any criminal action or proceeding had no reasonable cause to believe his conduct was unlawful.

 

To the extent that a director, officer, employee
or agent has been successful on the merits or otherwise in defense of any action, suit or proceeding, or in defense of any claim, issue
or matter, the Nevada Revised Statues provide that he must be indemnified by the Company against expenses, including attorney’s
fees, actually and reasonably incurred by him in connection with the defense.

 

Section 78.7502 of the Nevada Revised Statues
also provides that any discretionary indemnification, unless ordered by a court or advanced by the Company, may be made only as authorized
in the specific case upon a determination that indemnification of the director, officer, employee or agent is proper in the circumstances.
The determination must be made:

 

		●	By the stockholders;

		●	By the Company’s Board of Directors by majority vote of a quorum consisting of directors who were
not parties to that act, suit or proceeding;

		●	If a majority vote of a quorum consisting of directors who
were not parties to the act, suit or proceeding cannot be obtained, by independent legal counsel in a written opinion; or

		●	If a quorum consisting of directors who were not parties to the act, suit or proceeding cannot be obtained,
by independent legal counsel in a written opinion.

 

Nevada Control Share Acquisition Statutes

 

The Nevada control share law, if applicable, could
have the effect of discriminating against an existing or prospective holder of such securities as a result of such security holder owning
a substantial amount of securities.

 

Nevada’s “acquisition of controlling
interest” statutes, Sections 78.378 through 78.3793 of the Nevada Revised Statutes, contain provisions governing the acquisition
of a controlling interest in certain Nevada corporations. These “control share” laws provide generally that any person that
acquires a “controlling interest” in certain Nevada corporations may be denied voting rights, unless a majority of the disinterested
stockholders of the corporation elects to restore such voting rights. These laws provide that a person acquires a “controlling interest”
whenever a person acquires shares of a subject corporation that, but for the application of these provisions of the NRS, would enable
that person to exercise (A) one fifth or more, but less than one third, (B) one third or more, but less than a majority or (C) a majority
or more, of all of the voting power of the corporation in the election of directors. Once an acquirer crosses one of these thresholds,
shares which it acquired in the transaction and within the ninety days immediately preceding the date when the acquiring person acquired
or offered to acquire a controlling interest become “control shares” to which the voting restrictions described above apply.EX-4.1

 The Company represents and warrants to each Purchaser that: 

Section 5.1.    Organization; Power and Authority. The Company is a corporation duly
organized, validly existing and in good standing under the laws of its jurisdiction of incorporation, and is duly qualified as a foreign corporation and is in good standing in each jurisdiction in which such qualification is required by law, other
than those jurisdictions as to which the failure to be so qualified or in good standing could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The Company has the corporate power and authority to own
or hold under lease the properties it purports to own or hold under lease, to transact the business it transacts and proposes to transact, to execute and deliver this Agreement and the Notes and to perform the provisions hereof and thereof. 

Section 5.2.    Authorization, Etc. This Agreement and the Notes have been duly
authorized by all necessary corporate action on the part of the Company, and this Agreement constitutes, and upon execution and delivery thereof each Note will constitute, a legal, valid and binding obligation of the Company enforceable against the
Company in accordance with its terms, except as such enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditors’ rights generally and
(ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). 

Section 5.3.    Disclosure. The Company, through its agent, Barclays Capital Inc., has
delivered to each Purchaser a copy of an Investor Presentation, dated March 23, 2021 (the “Presentation”), relating to the transactions contemplated hereby. The Presentation fairly describes, in all material respects, the
general nature of the business and principal properties of the Company and its Subsidiaries. This Agreement, the Presentation, the financial statements listed in Schedule 5.5 and the documents, certificates or other writings delivered to the
Purchasers by or on behalf of the Company prior to April 6, 2021 in connection with the transactions contemplated hereby and identified in Schedule 5.3 (this Agreement, the Presentation and such documents, certificates or other writings and such
financial statements delivered to each Purchaser being referred to, collectively, as the “Disclosure Documents”), taken as a whole, do not contain any untrue statement of a material fact or omit to state any material fact
necessary to make the statements therein not misleading in light of the circumstances under which they were made; provided, that, to the extent any such reports, financial statements, certificates or other information was based on or
constitutes a forecast or a projection (including statements concerning future financial performance, ongoing business strategies or prospects or possible future actions, and 

  
 -5- 

			
	Evergy Missouri West, Inc.	  	Note Purchase Agreement

  

 
other forward-looking statements), the Company represents only that such information was prepared in good faith based upon assumptions believed to be reasonable at the respective times such
reports, financial statements, certificates or other information were prepared. Except as disclosed in the Disclosure Documents, since December 31, 2020, there has been no change in the financial condition, operations, business, properties or
prospects of the Company or any Subsidiary except changes that could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. There is no fact known to the Company that could reasonably be expected to have a
Material Adverse Effect that has not been set forth herein or in the Disclosure Documents. 

Section 5.4.    Organization and Ownership of Shares of Subsidiaries; Affiliates.
(a) Schedule 5.4 contains complete and correct lists of (i) the Company’s Subsidiaries, showing, as to each Subsidiary, the name thereof, the jurisdiction of its organization or incorporation, and the percentage of shares of each
class of its capital stock or similar equity interests outstanding owned by the Company and each other Subsidiary, (ii) the Company’s Affiliates, other than Subsidiaries, and (iii) the Company’s directors and senior officers. The
Company does not have any Significant Subsidiaries. 
 (b)    All of the outstanding shares of capital stock or similar
equity interests of each Subsidiary (other than any Inactive Subsidiary) shown in Schedule 5.4 as being owned by the Company and its Subsidiaries have been validly issued, are fully paid and
non-assessable and are owned by the Company or another Subsidiary free and clear of any Lien that is prohibited by this Agreement. 

(c)    Each Subsidiary is a corporation or other legal entity duly incorporated or organized, validly existing and, where
applicable, in good standing under the laws of its jurisdiction of organization, and is duly qualified as a foreign corporation or other legal entity and, where applicable, is in good standing in each jurisdiction in which such qualification is
required by law, other than those jurisdictions as to which the failure to be so qualified or in good standing could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Each such Subsidiary has the
corporate or other power and authority to own or hold under lease the properties it purports to own or hold under lease and to transact the business it transacts and proposes to transact, except as could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect. 
 (d)    No Subsidiary (other than any Inactive Subsidiary)
is subject to any legal, regulatory, contractual or other restriction (other than customary limitations imposed by corporate law or similar statutes) restricting the ability of such Subsidiary to pay dividends out of profits or make any other
similar distributions of profits to the Company or any of its Subsidiaries that owns outstanding shares of capital stock or similar equity interests of such Subsidiary. 

Section 5.5.    Financial Statements; Material Liabilities. The Company has delivered to
each Purchaser copies of the financial statements of the Company and Evergy listed on Schedule 5.5. All of such financial statements (including in each case the related schedules and notes) fairly present in all material respects the
consolidated financial position of the Company and Evergy and their respective Subsidiaries as of the respective dates specified in such Schedule and the consolidated results of their operations and cash flows for the respective periods so specified
and have been prepared in accordance with GAAP consistently applied throughout the 

  
 -6- 

			
	Evergy Missouri West, Inc.	  	Note Purchase Agreement

  

 
periods involved except as set forth in the notes thereto (subject, in the case of any interim financial statements, to normal year-end adjustments). The
Company and its Subsidiaries do not have any Material liabilities that are not disclosed in the Disclosure Documents. 

Section 5.6.    Compliance with Laws, Other Instruments, Etc. The execution, delivery and
performance by the Company of this Agreement and the Notes will not (i) contravene, result in any breach of, or constitute a default under, or result in the creation of any Lien in respect of any property of the Company or any Subsidiary under,
any indenture, mortgage, deed of trust, loan, purchase or credit agreement, lease, corporate charter or by-laws, shareholders agreement or any other agreement or instrument to which the Company or any
Subsidiary is bound or by which the Company or any Subsidiary or any of their respective properties may be bound or affected, (ii) conflict with or result in a breach of any of the terms, conditions or provisions of any order, judgment, decree
or ruling of any court, arbitrator or Governmental Authority applicable to the Company or any Subsidiary or (iii) violate any provision of any statute or other rule or regulation of any Governmental Authority applicable to the Company or any
Subsidiary. 
 Section 5.7.    Governmental Authorizations, Etc. No
consent, approval or authorization of, or registration, filing or declaration with, any Governmental Authority is required in connection with the execution, delivery or performance by the Company of this Agreement or the Notes except, in each case,
as have been obtained, including the FERC Order, and except for a Report of Securities Issued to be filed with the FERC (the “FERC Report”). 

Section 5.8.    Litigation; Observance of Agreements, Statutes and Orders.
(a) Except as disclosed in the Disclosure Documents (in note 12 to the Company’s audited consolidated financial statements for the year ended December 31, 2020), there are no actions, suits, investigations or proceedings pending or,
to the best knowledge of the Company, threatened against or affecting the Company or any Subsidiary (other than any Inactive Subsidiary) or any property of the Company or any Subsidiary in any court or before any arbitrator of any kind or before or
by any Governmental Authority that could, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 

(b)    Neither the Company nor any Subsidiary is (i) in default under any agreement or instrument to which it is a
party or by which it is bound, (ii) in violation of any order, judgment, decree or ruling of any court, arbitrator or Governmental Authority or (iii) in violation of any applicable law, ordinance, rule or regulation of any Governmental
Authority (including, without limitation, Environmental Laws, the USA PATRIOT Act or any of the other laws and regulations that are referred to in Section 5.16), which default or violation could, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect. 
 Section 5.9.    Taxes. The Company and
its Subsidiaries have filed all tax returns that are required to have been filed in any jurisdiction, and have paid all taxes shown to be due and payable on such returns and all other taxes and assessments levied upon them or their properties,
assets, income or franchises, to the extent such taxes and assessments have become due and payable and before they have become delinquent, except for any taxes and assessments (i) the amount of which, individually or in the aggregate, is not
Material or (ii) the amount, applicability or validity of which is currently being contested in good faith by appropriate proceedings and with respect to which the Company or a Subsidiary, as the case may be, has established adequate reserves
in accordance 

  
 -7- 

			
	Evergy Missouri West, Inc.	  	Note Purchase Agreement

  

 
with GAAP. The Company knows of no basis for any other tax or assessment that could, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The charges,
accruals and reserves on the books of the Company and its Subsidiaries in respect of U.S. federal, state or other taxes for all fiscal periods are adequate. The U.S. federal income tax liabilities of the Company and its Subsidiaries have
been finally determined (whether by reason of completed audits or the statute of limitations having run) for all fiscal years up to and including the fiscal year ended December 31, 2009. 

Section 5.10.    Title to Property; Leases. The Company has good and sufficient title to
its properties that individually or in the aggregate are Material, including all such properties reflected in the most recent audited balance sheet referred to in Section 5.5 or purported to have been acquired by the Company after such date
(except as sold or otherwise disposed of in the ordinary course of business), in each case free and clear of Liens prohibited by this Agreement, except for those defects in title and Liens that, individually or in the aggregate, would not have a
Material Adverse Effect. All Material leases are valid and subsisting and are in full force and effect in all material respects. No Subsidiary owns or leases any properties that, individually, or in the aggregate, are Material. 

Section 5.11.    Licenses, Permits, Etc. (a) The Company and its Subsidiaries own or
possess all licenses, permits, franchises, authorizations, patents, copyrights, proprietary software, service marks, trademarks and trade names, or rights thereto, that individually or in the aggregate are Material, without known conflict with the
rights of others. 
 (b)    To the best knowledge of the Company, no product or service of the Company or any of its
Subsidiaries infringes in any material respect any license, permit, franchise, authorization, patent, copyright, proprietary software, service mark, trademark, trade name or other right owned by any other Person. 

(c)    To the best knowledge of the Company, there is no Material violation by any Person of any right of the Company or
any of its Subsidiaries with respect to any license, permit, franchise, authorization, patent, copyright, proprietary software, service mark, trademark, trade name or other right owned or used by the Company or any of its Subsidiaries. 

Section 5.12.    Compliance with ERISA. (a) The Company and each ERISA Affiliate
have maintained, operated and administered each Plan in compliance with its terms and all applicable laws except for such instances of noncompliance as have not resulted in and could not, individually or in the aggregate, reasonably be expected to
result in a Material Adverse Effect. Neither the Company nor any ERISA Affiliate has incurred any liability pursuant to Title I or IV of ERISA or the provisions of the Code relating to “employee benefit plans” (as defined in
section 3(3) of ERISA), and no event, transaction, omission or condition has occurred or exists that could, individually or in the aggregate, reasonably be expected to result in the incurrence of any such liability by the Company or any ERISA
Affiliate pursuant to Title I or IV of ERISA or the Code, or in the imposition of any Lien on any of the rights, properties or assets of the Company or any ERISA Affiliate pursuant to Title I or IV of ERISA or to section 430(k) of the Code
or to any penalty or excise tax provisions under the Code or federal law or section 4068 of ERISA or by the granting of a security interest in connection with the amendment of a Plan, other than such liabilities or Liens as would not be
individually or in the aggregate Material. 

  
 -8- 

			
	Evergy Missouri West, Inc.	  	Note Purchase Agreement

  

 (b)    The present value of the aggregate benefit liabilities under each
of the Plans (other than Multiemployer Plans), determined as of the end of such Plan’s most recently ended plan year on the basis of the actuarial assumptions specified for funding purposes in such Plan’s most recent actuarial valuation
report, did not materially exceed the aggregate current value of the assets of such Plan allocable to such benefit liabilities. The term “benefit liabilities” has the meaning specified in section 4001 of ERISA and the terms
“current value” and “present value” have the meanings specified in section 3 of ERISA. 

(c)    The Company and its ERISA Affiliates have not incurred any withdrawal liability (and are not subject to contingent
withdrawal liability) under Title IV of ERISA in respect of any Multiemployer Plan that individually or in the aggregate are Material. 

(d)    The reasonably expected postretirement benefit obligation (determined as of the last day of the Company’s most
recently ended fiscal year in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 715-60, without regard to liabilities attributable to continuation coverage mandated
by section 4980B of the Code) of the Company and its Subsidiaries is not Material. 
 (e)    The execution and
delivery of this Agreement and the issuance and sale of the Notes hereunder will not involve any transaction that is subject to the prohibitions of section 406 of ERISA or in connection with which a tax could be imposed pursuant to
section 4975(c)(1)(A)(D) of the Code. The representation by the Company to each Purchaser in the first sentence of this Section 5.12(e) is made in reliance upon and subject to the accuracy of such Purchaser’s representation in
Section 6.2 as to the sources of the funds to be used to pay the purchase price of the Notes to be purchased by such Purchaser. 

(f)    The Company and its Subsidiaries do not sponsor, maintain, contribute or have an obligation to contribute to and do
not have any liability with respect to any Non-US Plans. 

Section 5.13.    Private Offering by Company. Neither the Company nor anyone acting on its behalf has
offered the Notes or any similar Securities for sale to, or solicited any offer to buy the Notes or any similar Securities from, or otherwise approached or negotiated in respect thereof with, any Person other than the Purchasers and not more than
forty (40) other Institutional Investors, each of which has been offered the Notes at a private sale for investment. Neither the Company nor anyone acting on its behalf has taken, or will take, any action that would subject the issuance or sale
of the Notes to the registration requirements of section 5 of the Securities Act or to the registration requirements of any Securities or blue sky laws of any applicable jurisdiction. 

Section 5.14.    Use of Proceeds; Margin Regulations. The Company will apply the proceeds
of the sale of the Notes hereunder to repay indebtedness and for general corporate purposes. No part of the proceeds from the sale of the Notes hereunder will be used, directly or indirectly, for the purpose of buying or carrying any margin stock
within the meaning of Regulation U of the Board of Governors of the Federal Reserve System (12 CFR 221), or for the purpose of buying or carrying or trading in any Securities under such circumstances as to involve the Company in a violation of
Regulation X of said Board (12 CFR 224) or to involve any broker or dealer in a violation of Regulation T of said Board (12 CFR 220). Margin stock does not constitute more than 5% of the value of the consolidated assets of the Company and
its Subsidiaries 

  
 -9- 

			
	Evergy Missouri West, Inc.	  	Note Purchase Agreement

  

 
and the Company does not have any present intention that margin stock will constitute more than 5% of the value of such assets. As used in this Section, the terms “margin stock”
and “purpose of buying or carrying” shall have the meanings assigned to them in said Regulation U. 

Section 5.15.    Existing Indebtedness; Future Liens. (a) Except as described
therein, Schedule 5.15 sets forth a complete and correct list of all outstanding Indebtedness of the Company and its Subsidiaries as of December 31, 2020 (including descriptions of the obligors and obligees, principal amounts outstanding,
any collateral therefor and any Guaranties thereof), since which date there has been no Material change in the amounts, interest rates, sinking funds, installment payments or maturities of the Indebtedness of the Company or its Subsidiaries. Neither
the Company nor any Subsidiary is in default and no waiver of default is currently in effect, in the payment of any principal or interest on any Indebtedness of the Company or such Subsidiary and no event or condition exists with respect to any
Indebtedness of the Company or any Subsidiary that would permit (or that with notice or the lapse of time, or both, would permit) one or more Persons to cause such Indebtedness to become due and payable before its stated maturity or before its
regularly scheduled dates of payment. No Subsidiary is a guarantor or borrower or otherwise obligated in respect of any Material Credit Facility. 

(b)    Except as disclosed in Schedule 5.15, neither the Company nor any Subsidiary has agreed or consented to cause
or permit any of its property, whether now owned or hereafter acquired, to be subject to a Lien that secures Indebtedness or to cause or permit in the future (upon the happening of a contingency or otherwise) any of its property, whether now owned
or hereafter acquired, to be subject to a Lien that secures Indebtedness. 
 (c)    Neither the Company nor any
Subsidiary is a party to, or otherwise subject to any provision contained in, any instrument evidencing Indebtedness of the Company or such Subsidiary, any agreement relating thereto or any other agreement (including, without limitation, its charter
or any other organizational document) which limits the amount of, or otherwise imposes restrictions on the incurring of, Indebtedness of the Company, except as disclosed in Schedule 5.15. 

Section 5.16.    Foreign Assets Control Regulations, Etc. (a) Neither the Company

violation of, or been charged or convicted under, any applicable U.S. Economic Sanctions Laws, Anti-Money Laundering Laws or Anti-Corruption Laws or (ii) to the
Company’s knowledge, is under investigation by any Governmental Authority for possible violation of any U.S. Economic Sanctions Laws, Anti-Money Laundering Laws or
Anti-Corruption Laws.

or will otherwise be used by the Company or any Controlled Entity, directly or indirectly, (A) in connection with any investment in, or any transactions or dealings with, any Blocked Person, (B) for any purpose that would cause any
Purchaser to be in violation of any U.S. Economic Sanctions Laws or (C) otherwise in violation of any U.S. Economic Sanctions Laws;

knowledge of any claim or has received any notice of any claim and no proceeding has been instituted asserting any claim against the Company or any of its Subsidiaries or any of their respective real properties or other assets now or formerly owned,

 -19- 

			
	Evergy Missouri West, Inc.	  	Note Purchase Agreement

  

 
date with respect to such principal amount. The Company will give each holder of Notes written notice of each optional prepayment under this Section 8.2 not less than ten days and not more
than 60 days prior to the date fixed for such prepayment unless the Company and the Required Holders agree to another time period pursuant to Section 17. Each such notice shall specify such date (which shall be a Business Day), the aggregate
principal amount and series of Notes to be prepaid on such date, the principal amount of each Note held by such holder to be prepaid (determined in accordance with Section 8.3), and the interest to be paid on the prepayment date with respect to
such principal amount being prepaid, and shall be accompanied by a certificate of a Senior Financial Officer as to the estimated Make-Whole Amount due in connection with such prepayment (calculated as if the date of such notice were the date of the
prepayment), setting forth the details of such computation. Two Business Days prior to such prepayment, the Company shall deliver to each holder of Notes of a series to be prepaid a certificate of a Senior Financial Officer (i) specifying the
calculation of such Make-Whole Amount as of the specified prepayment date and (ii) certifying that no Default or Event of Default then exists. 

Section 8.3.    Allocation of Partial Prepayments. In the case of each partial prepayment
of the Notes of any series pursuant to Section 8.2, the principal amount of the Notes to be prepaid shall be allocated among all of the Notes of such series at the time outstanding in proportion, as nearly as practicable, to the respective
unpaid principal amounts thereof not theretofore called for prepayment. 

Section 8.4.    Maturity; Surrender, Etc. In the case of each optional prepayment of
Notes pursuant to this Section 8, the principal amount of each Note to be prepaid shall mature and become due and payable on the date fixed for such prepayment, together with interest on such principal amount accrued to such date and the
applicable Make-Whole Amount, if any. From and after such date, unless the Company shall fail to pay such principal amount when so due and payable, together with the interest and Make-Whole Amount, if any, as aforesaid, interest on such principal
amount shall cease to accrue. Any Note paid or prepaid in full shall be surrendered to the Company and cancelled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal amount of any Note. 

Section 8.5.    Purchase of Notes. The Company will not and will not permit any Affiliate
to purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Notes except (a) upon the payment or prepayment of the Notes in accordance with the terms of this Agreement or (b) pursuant to an offer to
purchase made by the Company or an Affiliate pro rata to the holders of all Notes at the time outstanding upon the same terms and conditions. Any such offer shall provide each holder with sufficient information to enable it to make an informed
decision with respect to such offer, and shall remain open for at least 15 Business Days. The Company will promptly cancel all Notes acquired by it or any Affiliate pursuant to any payment, prepayment or purchase of Notes pursuant to any provision
of this Agreement and no Notes may be issued in substitution or exchange for any such Notes. 
 Section
8.6.     Make-Whole Amount. 
 “Make-Whole Amount” means, with respect to any Note, 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 Note over the amount of such Called Principal, provided that the Make-Whole

  
 -20- 

			
	Evergy Missouri West, Inc.	  	Note Purchase Agreement

  

 
Amount may in no event be less than zero. For the purposes of determining the Make-Whole Amount, the following terms have the following meanings: 

“Called Principal” means, with respect to any Note, the principal of such Note that is to be prepaid pursuant to
Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires. 

“Discounted Value” means, with respect to the Called Principal of any Note, 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 such Note is payable) equal to the Reinvestment Yield with respect to such Called Principal. 

“Reinvestment Yield” means, with respect to the Called Principal of any Note, .50% over the yield to maturity implied by the
yield(s) 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 on-the-run U.S. Treasury securities (“Reported”) having a maturity
equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there are no such U.S. Treasury securities Reported having a maturity equal to such Remaining Average Life, then such implied yield to maturity will be
determined by (a) converting U.S. Treasury bill quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between the yields Reported for the applicable most recently issued
actively traded on-the-run U.S. Treasury securities with the maturities (1) closest to and greater than such Remaining Average Life and (2) 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 Note. 

If such yields are not Reported or the yields Reported as of such time are not ascertainable (including by way of interpolation), then
“Reinvestment Yield” means, with respect to the Called Principal of any Note, .50% over the yield to maturity implied by the U.S. Treasury constant maturity 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 (or any comparable successor publication) for the U.S. Treasury constant maturity having a
term equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there is no such U.S. Treasury constant maturity having a term equal to such Remaining Average Life, such implied yield to maturity will be
determined by interpolating linearly between (1) the U.S. Treasury constant maturity so reported with the term closest to and greater than such Remaining Average Life and (2) the U.S. Treasury constant maturity so reported with
the term 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 Note. 

“Remaining Average Life” means, with respect to any Called Principal, the number of years 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 

  
 -21- 

			
	Evergy Missouri West, Inc.	  	Note Purchase Agreement

  

 
such Called Principal by (b) the number of years, computed on the basis of a 360-day year composed of twelve
30-day months and calculated to two decimal places, that will elapse 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 Note, 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 such Note, then 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
pursuant to Section 8.4 or Section 12.1. 
 “Settlement Date” means, with respect to the Called Principal of any
Note, the date on which such Called Principal is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires. 

Section 8.7.    Payments Due on Non-Business
Days. Anything in this Agreement or the Notes to the contrary notwithstanding (but without limiting the requirement in Section 8.4 that the notice of any optional prepayment specify a Business Day as the date fixed for such prepayment),
(x) subject to clause (y), any payment of interest on any Note that is due on a date that is not 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; and (y) any payment of principal of or Make-Whole Amount on any Note (including principal due on the Maturity Date of such Note) that is due on a date that is not a Business Day 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. 

Section 8.8.    Change of Control. 

(a)    Notice of Change of Control. The Company will, within five Business Days after the occurrence of a Change of
Control, give written notice of such Change of Control to each holder of Notes. Such notice shall contain and constitute an offer to prepay Notes as described in subparagraph (b) of this Section 8.8 and shall be accompanied by the
certificate described in subparagraph (e) of this Section 8.8. 
 (b)    Offer to Prepay Notes. The
offer to prepay Notes contemplated by subparagraph (a) of this Section 8.8 shall be an offer to prepay, in accordance with and subject to this Section 8.8, all, but not less than all, the Notes held by each holder (in this case only,
“holder” in respect of any Note registered in the name of a nominee for a disclosed beneficial owner means such beneficial owner) on a date specified in such offer (the “Proposed Prepayment Date”) that is not less than
30 days after the date of such offer and not more than 60 days after the date of the occurrence of a Change of Control. 

(c)    Acceptance. A holder of Notes may accept the offer to prepay all but not less than all of the Notes made
pursuant to this Section 8.8 by causing a notice of such acceptance to be delivered to the Company no later than 15 days after such holder’s receipt of such offer. A failure by a holder of Notes to respond to an offer to prepay made
pursuant to this Section 8.8 shall be deemed to constitute a rejection of such offer by such holder.

 (d)    Prepayment Price. Prepayment of the Notes to be prepaid

principal amount of each Note offered to be prepaid (which shall be the entire principal amount thereof); (iv) the interest that would be due on each Note offered to be prepaid, accrued to the Proposed Prepayment Date; (v) that the conditions
of this Section 8.8 have been fulfilled; and (vi) in reasonable detail, the nature and date of the Change of Control.

Subsidiaries to, maintain, with financially sound and reputable insurers, insurance with respect to their respective properties and businesses against such casualties and contingencies, of such types, on such terms and in such amounts (including

business and similarly situated.

Significant Subsidiaries to, file all tax returns required to be filed in any jurisdiction and to pay and discharge all taxes shown to be due and payable on such returns and all other taxes, assessments, governmental charges, or levies imposed on
them or any of their properties, assets, income or franchises, to the extent the same have become due and payable and before they have become delinquent and all claims for which sums have become due and payable that have or might become a Lien on
properties or assets of the Company or any Subsidiary, provided that neither the Company nor any Subsidiary need pay any such tax, assessment, charge, levy or claim if (i) the amount, applicability or validity thereof is contested by the
Company or such Subsidiary on a timely basis in good faith and in appropriate proceedings, and the Company or a Subsidiary has established adequate reserves therefor in accordance with GAAP on the books of the Company or such Subsidiary or
(ii) the nonpayment of all such taxes, assessments, charges, levies and claims could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

at all times preserve and keep its corporate existence in full force and effect. Subject to Section 10.2 the Company will at all times preserve and keep in full force and effect the corporate existence of each of its Significant Subsidiaries
(unless merged into the Company or a Wholly-Owned Subsidiary) and all rights and franchises of the Company and its Significant Subsidiaries unless, in the good faith judgment of the Company, the termination of or failure to preserve and keep in full
force and effect such corporate existence, right or franchise could not, individually or in the aggregate, have a Material Adverse Effect. 

Section 9.6.    Books and Records. The Company will, and will cause each of its
Subsidiaries to, maintain proper books of record and account in conformity with GAAP and all applicable requirements of any Governmental Authority having legal or regulatory jurisdiction over the Company or such Subsidiary, as the case may be. The
Company will, and will cause each of its Subsidiaries to, keep books, records and accounts which, in reasonable detail, accurately reflect all transactions and dispositions of assets. The Company and its Subsidiaries have devised a system of
internal accounting controls sufficient to provide reasonable assurances that their respective books, records, and accounts accurately reflect all transactions and dispositions of assets and the Company will, and will cause each of its Subsidiaries
to, continue to maintain such system.

Evergy to make payments on the Notes (whether for principal, interest, Make-Whole Amount or otherwise) or perform any obligation hereunder, shall be deemed to be discharged and the Subsequent Parent Note Guaranty shall be terminated and released and
no longer in effect (except, in each case, as provided in clauses (i) and (ii) below) in the event that Evergy ceases to be a guarantor of, or jointly and severally liable for, Indebtedness of the Company in respect of each Material Credit
Facility. In such an event, at any time after the execution and delivery of the Subsequent Parent Note Guaranty pursuant to Section 9.8(a), the Subsequent Parent Note Guaranty shall immediately be terminated and released and no longer in

	SECTION 12.	 REMEDIES ON DEFAULT, ETC.

 Section 12.1.    Acceleration. (a) If an Event of Default
with respect to the Company described in Section 11(g) or (h) (other than an Event of Default described in clause (i) of Section 11(g) or described in clause (vi) of Section 11(g) by virtue of the fact that such
clause encompasses clause (i) of Section 11(g)) has occurred, all the Notes then outstanding shall automatically become immediately due and payable. 

(b)    If any other Event of Default has occurred and is continuing, the Required Holders at any time at its or their
option, by notice or notices to the Company, declare all the Notes then outstanding to be immediately due and payable. 

(c)    If any Event of Default described in Section 11(a) or (b) has occurred and is continuing, any holder or
holders of the Notes at the time outstanding affected by such Event of Default may at any time, at its or their option, by notice or notices to the Company, declare all the Notes held by it or them to be immediately due and payable. 

Upon any Notes becoming due and payable under this Section 12.1, whether automatically or by declaration, such Notes will forthwith
mature and the entire unpaid principal amount of such Notes, plus (x) all accrued and unpaid interest thereon (including, without limitation, interest accrued thereon at the applicable Default Rate) and (y) the Make-Whole Amount determined
in respect of such principal amount (to the full extent permitted by applicable law), shall all be immediately due and payable, in each and every case without presentment, demand, protest or further notice, all of which are hereby waived. The
Company acknowledges, and the parties hereto agree, that each holder of a Note has the right to maintain its investment in the Notes free from repayment by the Company (except as herein specifically provided for) and that the provision for payment
of a Make-Whole Amount by the Company in the event that the Notes are prepaid or are accelerated as a result of an Event of Default, is intended to provide compensation for the deprivation of such right under such circumstances.

 Section 12.2.    Other Remedies. If any
Default or Event of Default has occurred and is continuing, and irrespective of whether any Notes have become or have been declared immediately due and payable under Section 12.1, the holder of any Note at the time outstanding may proceed to
protect and enforce the rights of such holder by an action at law, suit in equity or other appropriate proceeding, whether for the specific performance of any agreement contained herein or in any Note, the Initial Parent Note Guaranty, any
Subsidiary Guaranty or any Subsequent Parent Note Guaranty, or for an injunction against a violation of any of the terms hereof or thereof, or in aid of the exercise of any power granted hereby or thereby or by law or otherwise. 

Section 12.3.    Rescission. At any time after any Notes have been declared due and
payable pursuant to Section 12.1(b) or (c), the Required Holders, by written notice to the Company, may rescind and annul any such declaration and its consequences if (a) the Company has paid all overdue interest on the Notes, all
principal of and Make-Whole Amount, if any, on any Notes that are due and payable and are unpaid other than by reason of such declaration, and all interest on such overdue principal and Make-Whole Amount, if any, and (to the extent permitted by
applicable law) any overdue interest in respect of the Notes, at the applicable Default Rate, (b) neither the Company nor any other Person shall have paid any amounts which have become due solely by reason of such declaration, (c) all
Events of Default and Defaults, other than non-payment of amounts that have become due solely by reason of such declaration, have been cured or have been waived pursuant to Section 17, and (d) no
judgment or decree has been entered for the payment of any monies due pursuant hereto or to the Notes. No rescission and annulment under this Section 12.3 will extend to or affect any subsequent Event of Default or Default or impair any right
consequent thereon. 
 Section 12.4.    No Waivers or Election of Remedies, Expenses,
Etc. No course of dealing and no delay on the part of any holder of any Note in exercising any right, power or remedy shall operate as a waiver thereof or otherwise prejudice such holder’s rights, powers or remedies. No right, power or
remedy conferred by this Agreement, the Initial Parent Note Guaranty, any Subsidiary Guaranty, any Subsequent Parent Note Guaranty or any Note upon any holder thereof shall be exclusive of any other right, power or remedy referred to herein or
therein or now or hereafter available at law, in equity, by statute or otherwise. Without limiting the obligations of the Company under Section 15, the Company will pay to the holder of each Note on demand such further amount as shall be
sufficient to cover all costs and expenses of such holder incurred in any enforcement or collection under this Section 12, including, without limitation, reasonable attorneys’ fees, expenses and disbursements.

transfer, the Person(s) in whose name any Note(s) shall be registered shall be deemed and treated as the owner and holder thereof for all purposes hereof, and the Company shall not be affected by any notice or knowledge to the contrary. The Company
shall give to any holder of a Note that is an Institutional Investor promptly upon request therefor, a complete and correct copy of the names and addresses of all registered holders of the Notes. 

Section 13.2.    Transfer and Exchange of Notes. Upon surrender of any Note to the
Company at the address and to the attention of the designated officer (all as specified in Section 18(iii)), for registration of transfer or exchange (and in the case of a surrender for registration of transfer accompanied by a written
instrument of transfer duly executed by the registered holder of such Note or such holder’s attorney duly authorized in writing and accompanied by the relevant name, address and other information for notices of each transferee of such Note or
part thereof), within ten Business Days thereafter, the Company shall execute and deliver, at the Company’s expense (except as provided below), one or more new Notes of the same series (as requested by the holder thereof) in exchange therefor,

transfer by a holder of its entire holding of Notes of a series, one Note of such series may be in a denomination of less than $100,000. Any transferee, by its acceptance of a Note registered in its name (or the name of its nominee), shall be deemed

theft, destruction or mutilation); and 
 (b)    in the case of (i) loss, theft or destruction, of
indemnity reasonably satisfactory to it (provided that if the holder of such Note is, or is a nominee for, an original Purchaser or another holder of a Note with a minimum net worth of at least $50,000,000 or a Qualified Institutional Buyer,
such Person’s own unsecured agreement of indemnity shall be deemed to be satisfactory) or (ii) in the case of mutilation, upon surrender and cancellation thereof, 

within ten Business Days thereafter, the Company at its own expense shall execute and deliver, in lieu thereof, a new Note of the same series, dated and
bearing interest from the date to which interest shall have been paid on such lost, stolen, destroyed or mutilated Note or dated the date of such lost, stolen, destroyed or mutilated Note if no interest shall have been paid thereon.

payment or prepayment in full of any Note, such Purchaser shall surrender such Note for cancellation, reasonably promptly after any such request, to the Company at its principal executive office or at the place of payment most recently designated by
the Company pursuant to Section 14.1. Prior to any sale or other disposition of any Note held by a Purchaser or its nominee, such Purchaser will, at its election, either endorse thereon the amount of principal paid thereon and the last date to
which interest has been paid thereon or surrender such Note to the Company in exchange for a new Note or Notes pursuant to Section 13.2. The Company will afford the benefits of this Section 14.2 to any Institutional Investor that is the
direct or indirect transferee of any Note purchased by a Purchaser under this Agreement and that has made the same agreement relating to such Note as the Purchasers have made in this Section 14.2.

Code) and such additional documentation as may be necessary for the Company to comply with its obligations under FATCA and to determine that such holder has complied with such holder’s obligations under FATCA or to determine the amount (if any)
to deduct and withhold from any such payment made to such holder. Nothing in this Section 14.3 shall require any holder to provide information that is confidential or proprietary to such holder unless the Company is required to obtain such
information under FATCA and, in such event, the Company shall treat any such information it receives as confidential.

executed or true and correct copies of each amendment, waiver or consent effected pursuant to this Section 17, the Initial Parent Note Guaranty, any Subsidiary Guaranty or any Subsequent Parent Note Guaranty to each holder of a Note promptly
following the date on which it is executed and delivered by, or receives the consent or approval of, the requisite holders of the Notes. 

(b)    Payment. The Company will not directly or indirectly pay or cause to be paid any remuneration, whether by
way of supplemental or additional interest, fee or otherwise, or grant any security or provide other credit support, to any holder of a Note as consideration for or as an inducement to the entering into by such holder of any waiver or amendment of
any of the terms and provisions hereof or of the Initial Parent Note Guaranty, any Subsidiary Guaranty or any Subsequent Parent Note Guaranty unless such remuneration is concurrently paid, or security is concurrently granted or other credit support

any right consequent thereon. No course of dealing between the Company and any holder of a Note and no delay in exercising any rights hereunder or under any Note, the Initial Parent Note Guaranty, any Subsidiary Guaranty or any Subsequent Parent
Note Guaranty shall operate as a waiver of any rights of any holder of such Note.

applicable law, any such reproduction shall be admissible in evidence as the original itself in any judicial or administrative proceeding (whether or not the original is in existence and whether or not such reproduction was made by such Purchaser in
the regular course of business) and any enlargement, facsimile or further reproduction of such reproduction shall likewise be admissible in evidence. This Section 19 shall not prohibit the Company or any other holder of Notes from contesting

behalf of the Company or any Subsidiary in connection with the transactions contemplated by or otherwise pursuant to this Agreement that is proprietary in nature and that was clearly marked or labeled or otherwise adequately identified when received
by such Purchaser as being confidential information of the Company or such Subsidiary, provided that such term does not include information that (a) was publicly known or otherwise known to

	Evergy Missouri West, Inc.	  	Note Purchase Agreement

  

 
such Purchaser prior to the time of such disclosure, (b) subsequently becomes publicly known through no act or omission by such Purchaser or any Person acting on such Purchaser’s
behalf, (c) otherwise becomes known to such Purchaser other than through disclosure by the Company or any Subsidiary or (d) constitutes financial statements delivered to such Purchaser under Section 7.1 that are otherwise publicly
available. Each Purchaser will maintain the confidentiality of such Confidential Information in accordance with procedures adopted by such Purchaser in good faith to protect confidential information of third parties delivered to such Purchaser,
provided that such Purchaser may deliver or disclose Confidential Information to (i) its directors, officers, employees, agents, attorneys, trustees and affiliates (to the extent such disclosure reasonably relates to the administration
of the investment represented by its Notes), (ii) its auditors, financial advisors and other professional advisors who agree to hold confidential the Confidential Information substantially in accordance with this Section 20, (iii) any
other holder of any Note, (iv) any Institutional Investor to which it sells or offers to sell such Note or any part thereof or any participation therein (if such Person has agreed in writing prior to its receipt of such Confidential Information
to be bound by this Section 20), (v) any Person from which it offers to purchase any Security of the Company (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by this Section 20),

Purchaser, (x) in response to any subpoena or other legal process, (y) in connection with any litigation to which such Purchaser is a party or (z) if an Event of Default has occurred and is continuing, to the extent such Purchaser may
reasonably determine such delivery and disclosure to be necessary or appropriate in the enforcement or for the protection of the rights and remedies under such Purchaser’s Notes, this Agreement, the Initial Parent Note Guaranty, any Subsidiary
Guaranty or any Subsequent Parent Note Guaranty. Each holder of a Note, by its acceptance of a Note, will be deemed to have agreed to be bound by and to be entitled to the benefits of this Section 20 as though it were a party to this Agreement.
On reasonable request by the Company in connection with the delivery to any holder of a Note of information required to be delivered to such holder under this Agreement or requested by such holder (other than a holder that is a party to this
Agreement or its nominee), such holder will enter into an agreement with the Company embodying this Section 20. 
 In the event that as
a condition to receiving access to information relating to the Company or its Subsidiaries in connection with the transactions contemplated by or otherwise pursuant to this Agreement, any Purchaser or holder of a Note is required to agree to a
confidentiality undertaking (whether through IntraLinks, another secure website, a secure virtual workspace or otherwise) which is different from this Section 20, this Section 20 shall not be amended thereby and, as between such Purchaser
or such holder and the Company, this Section 20 shall supersede any such other confidentiality undertaking. 
  

	SECTION 21.	 SUBSTITUTION OF PURCHASER. 

Each Purchaser shall have the right to substitute any one of its Affiliates or another Purchaser or any one of such other Purchaser’s
Affiliates (a “Substitute Purchaser”) as the

purchaser of the Notes that it has agreed to purchase hereunder, by written notice to the Company, which notice shall be signed by both such Purchaser and such Substitute Purchaser, shall contain
such Substitute Purchaser’s agreement to be bound by this Agreement and shall contain a confirmation by such Substitute Purchaser of the accuracy with respect to it of the representations set forth in Section 6. Upon receipt of such
notice, any reference to such Purchaser in this Agreement (other than in this Section 21), shall be deemed to refer to such Substitute Purchaser in lieu of such original Purchaser. In the event that such Substitute Purchaser is so substituted
as a Purchaser hereunder and such Substitute Purchaser thereafter transfers to such original Purchaser all of the Notes then held by such Substitute Purchaser, upon receipt by the Company of notice of such transfer, any reference to such Substitute
Purchaser as a “Purchaser” in this Agreement (other than in this Section 21), shall no longer be deemed to refer to such Substitute Purchaser, but shall refer to such original Purchaser, and such original Purchaser shall again have
all the rights of an original holder of the Notes under this Agreement. 
  

	SECTION 22.	 MISCELLANEOUS. 

Section 22.1.    Successors and Assigns. All covenants and other agreements contained in
this Agreement by or on behalf of any of the parties hereto bind and inure to the benefit of their respective successors and assigns (including, without limitation, any subsequent holder of a Note) whether so expressed or not. 

Section 22.2.    Accounting Terms. All accounting terms used herein which are not
expressly defined in this Agreement have the meanings respectively given to them in accordance with GAAP. Except as otherwise specifically provided herein, (i) all computations made pursuant to this Agreement shall be made in accordance with
GAAP, and (ii) all financial statements shall be prepared in accordance with GAAP. For purposes of determining compliance with this Agreement (including, without limitation, Section 9, Section 10 and the definition of
“Indebtedness”), any election by the Company to measure any financial liability using fair value (as permitted by Financial Accounting Standards Board Accounting Standards Codification Topic No. 825-10-25 – Fair Value Option, International Accounting Standard 39 – Financial Instruments: Recognition and Measurement or any similar accounting standard) shall
be disregarded and such determination shall be made as if such election had not been made. 

Section 22.3.    Severability. Any provision of this Agreement that is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall (to the full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction. 

Section 22.4.    Construction, Etc. Each covenant contained herein shall be construed
(absent express provision to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other

brought in an inconvenient forum. 
 (b)    The Company agrees, to the fullest extent permitted by applicable law, that
a final judgment in any suit, action or proceeding of the nature referred to in Section 22.7(a) brought in any such court shall be conclusive and binding upon it subject to rights of appeal, as the case may be, and may be enforced in the
courts of the United States of America or the State of New York (or any other courts to the jurisdiction of which it or any of its assets is or may be subject) by a suit upon such judgment. 

(c)    The Company consents to process being served by or on behalf of any holder of Notes in any suit, action or
proceeding of the nature referred to in Section 22.7(a) by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, return receipt requested, to it at its address specified in

use a paying agent to make payments due hereunder and under the Notes. The Company hereby acknowledges that its use of a paying agent for such purposes does not relieve it of any of its obligations under this Agreement or the Notes and any failure

FORM OF GUARANTY AGREEMENT 

THIS GUARANTY AGREEMENT, dated as of
[                    ] (this “Guaranty Agreement”), is made by Evergy, Inc., a Missouri corporation (the
“Guarantor”) in favor of the Purchasers (as defined below) and the other holders from time to time of the Notes (as defined below). The Purchasers and such other holders are herein collectively called the “holders”
and individually a “holder.” 
 PRELIMINARY STATEMENTS: 

I.    Evergy Missouri West, Inc., a Delaware corporation (the “Company”), entered into a Note Purchase
Agreement dated April 20, 2021 (as amended, modified, supplemented or restated from time to time, the “Note Agreement”) with the Persons listed on the signature pages thereto (the “Purchasers”). Capitalized terms
used herein have the meanings specified in the Note Agreement unless otherwise defined herein. 
 II.    The
Company issued, pursuant to the Note Agreement, (i) $350,000,000 aggregate principal amount of 2.86% Senior Notes due April 20, 2031, (ii) $75,000,000 aggregate principal amount of 3.01% Senior Notes due April 20, 2033 and (iii)
$75,000,000 aggregate principal amount of 3.21% Senior Notes due April 20, 2036 (collectively, the “Initial Notes”). The Initial Notes and any other Notes that may from time to time be issued pursuant to the Note Agreement (including
any notes issued in substitution for any of the Notes) are herein collectively called the “Notes” and individually a “Note.” 

III.    Section 9.8 of the Note Agreement sets forth the conditions under which this Guaranty Agreement is to be executed
by the Guarantor and delivered to the holders. 
 IV.    The Guarantor will receive direct and indirect benefits from
the financing arrangements contemplated by the Note Agreement. The Board of Directors of the Guarantor has determined that the incurrence of such obligations is in the best interests of the Guarantor. 

NOW THEREFORE, in compliance with the Note Agreement, and in consideration of, the execution and delivery of the Note Agreement and the
purchase of the Notes by each of the Purchasers, the Guarantor hereby covenants and agrees with, and represents and warrants to each of the holders as follows: 

SECTION 1. GUARANTY. 
 The Guarantor
hereby irrevocably and unconditionally guarantees to each holder, the due and punctual payment in full of (a) the principal of, Make-Whole Amount, if any, and interest on (including, without limitation, interest accruing after the filing of any
petition in bankruptcy, or 

  
 SCHEDULE C

 (to Note Purchase Agreement) 

 
the commencement of any insolvency, reorganization or like proceeding, whether or not a claim for post-filing or post-petition interest is allowed in such proceeding), and any other amounts due
under, the Notes when and as the same shall become due and payable (whether at stated maturity or by required or optional prepayment or by acceleration or otherwise) and (b) any other sums which may become due under the terms and provisions of
the Notes or the Note Agreement (all such obligations described in clauses (a) and (b) above are herein called the “Guaranteed Obligations”). The guaranty in the preceding sentence is an absolute, present and continuing
guaranty of payment and not of collectability and is in no way conditional or contingent upon any attempt to collect from the Company or any other guarantor of the Notes, if any, or upon any other action, occurrence or circumstance whatsoever. In
the event that the Company shall fail to pay any of such Guaranteed Obligations, the Guarantor agrees to pay the same when due to the holders entitled thereto, without demand, presentment, protest or notice of any kind, in lawful money of the United
States of America, pursuant to the requirements for payment specified in the Notes and the Note Agreement. Each default in payment of any of the Guaranteed Obligations shall give rise to a separate cause of action hereunder and separate suits may be
brought hereunder as each cause of action arises. The Guarantor agrees that the Notes issued in connection with the Note Agreement may (but need not) make reference to this Guaranty Agreement. 

The Guarantor agrees to pay and to indemnify and save each holder harmless from and against any damage, loss, cost or expense (including
attorneys’ fees) which such holder may incur or be subject to as a consequence, direct or indirect, of (x) any breach by the Guarantor or by the Company of any warranty, covenant, term or condition in, or the occurrence of any default
under, this Guaranty Agreement, the Notes or the Note Agreement, together with all expenses resulting from the compromise or defense of any claims or liabilities arising as a result of any such breach or default, (y) any legal action commenced
to challenge the validity or enforceability of this Guaranty Agreement, the Notes, the Note Agreement or any other instrument referred to therein and (z) enforcing or defending (or determining whether or how to enforce or defend) the provisions
of this Guaranty Agreement. 
 Notwithstanding any provision to the contrary contained herein or in the Note Agreement or the Notes, the
obligations of the Guarantor under this Guaranty Agreement, the Note Agreement and the Notes shall be limited to an aggregate amount equal to the largest amount that would not render such obligations subject to avoidance under the federal bankruptcy
laws or any comparable provision of any applicable state law. 
 The Guarantor hereby acknowledges and agrees that the Guarantor’s
liability hereunder is joint and several with any other Person(s) who may guarantee the obligations and Indebtedness under and in respect of the Notes and the Note Agreement. 

  
 2 

 SECTION 2. OBLIGATIONS ABSOLUTE. 

The obligations of the Guarantor hereunder shall be primary, absolute, irrevocable and unconditional, irrespective of the validity or
enforceability of the Notes, the Note Agreement or any other instrument referred to therein, shall not be subject to any counterclaim, setoff, deduction or defense based upon any claim the Guarantor may have against the Company or any holder or
otherwise, and shall remain in full force and effect without regard to, and shall not be released, discharged or in any way affected by, any circumstance or condition whatsoever (whether or not the Guarantor shall have any knowledge or notice
thereof), including, without limitation: (a) any amendment to, modification of, supplement to or restatement of the Notes or the Note Agreement (it being agreed that the obligations of the Guarantor hereunder shall apply to the Notes or the
Note Agreement as so amended, modified, supplemented or restated) or any assignment or transfer of any thereof or of any interest therein, or any furnishing, acceptance or release of any security for the Notes; (b) any waiver, consent,
extension, indulgence or other action or inaction under or in respect of the Notes or the Note Agreement; (c) any bankruptcy, insolvency, arrangement, reorganization, readjustment, composition, liquidation or similar proceeding with respect to
the Company or its property; (d) any merger, amalgamation or consolidation of the Guarantor or of the Company into or with any other Person or any sale, lease or transfer of any or all of the assets of the Guarantor or of the Company to any
Person; (e) any failure on the part of the Company for any reason to comply with or perform any of the terms of any other agreement with the Guarantor; (f) any failure on the part of any holder to obtain, maintain, register or otherwise
perfect any security; or (g) any other event or circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor (whether or not similar to the foregoing), and in any event however material or prejudicial
it may be to the Guarantor or to any subrogation, contribution or reimbursement rights the Guarantor may otherwise have. Except as provided in Section 9.8(b) of the Note Agreement, the Guarantor covenants that its obligations hereunder will not
be discharged except by indefeasible payment in full in cash of all of the Guaranteed Obligations and all other obligations hereunder. 
 SECTION 3.
WAIVER. 
 The Guarantor unconditionally waives to the fullest extent permitted by law, (a) notice of acceptance hereof, of any
action taken or omitted in reliance hereon and of any default by the Company in the payment of any amounts due under the Notes, the Note Agreement or any other instrument referred to therein, and of any of the matters referred to in Section 2
hereof, (b) all notices which may be required by statute, rule of law or otherwise to preserve any of the rights of any holder against the Guarantor, including, without limitation, presentment to or demand for payment from the Company or the
Guarantor with respect to any Note, notice to the Company or to the Guarantor of default or protest for nonpayment or dishonor and the filing of claims with a court in the event of the bankruptcy of the Company, (c) any right to require any
holder to enforce, 

  
 3 

 
assert or exercise any right, power or remedy including, without limitation, any right, power or remedy conferred in the Note Agreement or the Notes, (d) any requirement for diligence on the
part of any holder and (e) any other act or omission or thing or delay in doing any other act or thing which might in any manner or to any extent vary the risk of the Guarantor or otherwise operate as a discharge of the Guarantor or in any
manner lessen the obligations of the Guarantor hereunder. 
 SECTION 4. OBLIGATIONS UNIMPAIRED. 

The Guarantor authorizes the holders, without notice or demand to the Guarantor and without affecting its obligations hereunder, from time to
time: (a) to renew, compromise, extend, accelerate or otherwise change the time for payment of, all or any part of the Notes, the Note Agreement or any other instrument referred to therein; (b) to change any of the representations,
covenants, events of default or any other terms or conditions of or pertaining to the Notes, the Note Agreement or any other instrument referred to therein, including, without limitation, decreases or increases in amounts of principal, rates of
interest, the Make-Whole Amount or any other obligation; (c) to take and hold security for the payment of the Notes, the Note Agreement or any other instrument referred to therein, for the performance of this Guaranty Agreement or otherwise for
the Indebtedness guaranteed hereby and to exchange, enforce, waive, subordinate and release any such security; (d) to apply any such security and to direct the order or manner of sale thereof as the holders in their sole discretion may
determine; (e) to obtain additional or substitute endorsers or guarantors; (f) to exercise or refrain from exercising any rights against the Company and others; and (g) to apply any sums, by whomsoever paid or however realized, to the
payment of the Guaranteed Obligations and all other obligations owed hereunder. The holders shall have no obligation to proceed against any additional or substitute endorsers or guarantors or to pursue or exhaust any security provided by the
Company, the Guarantor or any other Person or to pursue any other remedy available to the holders. 
 If an event permitting the
acceleration of the maturity of the principal amount of any Notes shall exist and such acceleration shall at such time be prevented or the right of any holder to receive any payment on account of the Guaranteed Obligations shall at such time be
delayed or otherwise affected by reason of the pendency against the Company, the Guarantor or any other guarantors of a case or proceeding under a bankruptcy or insolvency law, the Guarantor agrees that, for purposes of this Guaranty Agreement and
its obligations hereunder, the maturity of such principal amount shall be deemed to have been accelerated with the same effect as if the holder thereof had accelerated the same in accordance with the terms of the Note Agreement, and the Guarantor
shall forthwith pay such accelerated Guaranteed Obligations. 

  
 4 

 SECTION 5. SUBROGATION AND SUBORDINATION. 

(a) The Guarantor will not exercise any rights which it may have acquired by way of subrogation under this Guaranty Agreement, by any payment
made hereunder or otherwise, or accept any payment on account of such subrogation rights, or any rights of reimbursement, contribution or indemnity or any rights or recourse to any security for the Notes or this Guaranty Agreement unless and until
all of the Guaranteed Obligations shall have been indefeasibly paid in full in cash. 
 (b) The Guarantor hereby subordinates the payment of
all Indebtedness of the Company and other obligations of the Company or any other guarantor of the Guaranteed Obligations that is, in each case, owing to the Guarantor, whether now existing or hereafter arising, including, without limitation, all
rights and claims described in clause (a) of this Section 5, to the indefeasible payment in full in cash of all of the Guaranteed Obligations. If the Required Holders so request, any such Indebtedness or other obligations shall be enforced
and performance received by the Guarantor as trustee for the holders and the proceeds thereof shall be paid over to the holders promptly, in the form received (together with any necessary endorsements) to be applied to the Guaranteed Obligations,
whether matured or unmatured, as may be directed by the Required Holders, but without reducing or affecting in any manner the liability of the Guarantor under this Guaranty Agreement. 

(c) If any amount or other payment is made to or accepted by the Guarantor in violation of any of the preceding clauses (a) and (b) of
this Section 5, such amount shall be deemed to have been paid to the Guarantor for the benefit of, and held in trust for the benefit of, the holders and shall be paid over to the holders promptly, in the form received (together with any

and agrees not to assert, by way of motion, as a defense or otherwise, any claim that it is not subject to the jurisdiction of any such court, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or
proceeding brought in any such court and any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum.

address of which such holder shall then have been notified pursuant to Section 18 of the Note Agreement. The Guarantor agrees that such service upon receipt (i) shall be deemed in every respect effective service of process upon it in any
such suit, action or proceeding and (ii) shall, to the fullest extent permitted by applicable law, be taken and held to be valid personal service upon and personal delivery to it. Notices hereunder shall be conclusively presumed received as
evidenced by a delivery receipt furnished by the United States Postal Service or any reputable commercial delivery service.
