11. Indemnification and Contribution.

(a) Evergy Missouri West and the Issuer, jointly and severally agree to indemnify and hold harmless each Underwriter, its directors, officers, employees and agents, and each person, if any, who controls any Underwriter within the meaning of the Securities Act or the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which such Underwriter, director, officer, employee, agent or controlling person may become subject under the Securities Act, the Exchange Act or any other federal or state statutory law or regulation at common law or otherwise, insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any amendment or supplement thereto, including any information deemed to be a part thereof pursuant to Rule 430B of the Securities Act, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) any untrue statement or alleged untrue statement of a material fact included in any Pricing Prospectus, Pricing Package, the Final Prospectus, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto), or any other materials or information provided to investors by, or with approval of, the Issuer or Evergy Missouri West in connection with the offering of the Bonds, including any “roadshow” (as defined in Rule 433 under the Securities Act) or investor presentation made to investors by the Issuer or Evergy Missouri West (whether in person or

- 26 -

electronically) including, without limitation, the materials listed on Schedule III hereto, or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; and to reimburse each Underwriter, its officers, directors, employees, agents and controlling persons for any and all expenses (including the reasonable fees and disbursements of counsel chosen by the Underwriters) as such expenses are reasonably incurred by such Underwriter, officer, director, employee, agent or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to Evergy Missouri West, the Issuer, or its representatives or agents, by or on behalf of any Underwriter through the Underwriters specifically for inclusion therein, it being understood and agreed that the only such information furnished to Evergy Missouri West by the Underwriters in writing expressly for use in such foregoing documents is set forth in Schedule IV hereto (the “Underwriter Information”) or arising out of, or based upon, statements in or omissions from that part of the Registration Statement that shall constitute the Statement of Eligibility under the Trust Indenture Act of the Indenture Trustee with respect to any indenture qualified pursuant to the Registration Statement.

(b) Each Underwriter severally and not jointly agrees to indemnify and hold harmless Evergy Missouri West and the Issuer, each of Evergy Missouri West’s and the Issuer’s respective directors and managers, officers, employees, affiliates and each person who controls the Issuer or Evergy Missouri West within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from Evergy Missouri West and the Issuer to each Underwriter, but only with reference to the Underwriter Information.

(c) Promptly after receipt by an indemnified party under this Section 11 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 11, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right

- 27 -

to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (A) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (B) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (C) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (D) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate counsel (in addition to one local counsel) for all such indemnified parties. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding; and (ii) does not include any statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of any indemnified party. No indemnifying party will be liable for any settlement of any such action effected without its prior written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment of the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 11 is unavailable to or insufficient to hold harmless an indemnified party for any reason, Evergy Missouri West, the Issuer and the Underwriters severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively “Losses”) to which Evergy Missouri West, the Issuer and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by Evergy Missouri West or the Issuer on the one hand and by the Underwriters on the other from the offering of the Bonds. If the allocation provided by the immediately preceding sentence is unavailable for any reason, Evergy Missouri West, the Issuer and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of Evergy Missouri West or the Issuer on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by Evergy Missouri West or the Issuer shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Underwriters shall be

- 28 -

deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Final Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by Evergy Missouri West or the Issuer on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. Evergy Missouri West, the Issuer and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the underwriting discount or commission applicable to the Bonds purchased by such Underwriter hereunder as set forth on the cover page of the Final Prospectus exceeds the amount of any damages that such Underwriter has otherwise been required to pay or has paid by reason of such untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 11, each person who controls an Underwriter within the meaning of either the Securities Act or the Exchange Act and each director, officer and employee of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls Evergy Missouri West or the Issuer within the meaning of either the Securities Act or the Exchange Act, each officer, manager, employee, director, or affiliate of Evergy Missouri West or the Issuer, as applicable, shall have the same rights to contribution as Evergy Missouri West or the Issuer, as applicable, subject in each case to the applicable terms and conditions of this paragraph (d).

12. Termination. This Underwriting Agreement may be terminated, at any time prior to the Closing Date with respect to the Bonds by the Underwriters by written notice to the Issuer if after the date hereof and at or prior to the Closing Date (a) there shall have occurred any general suspension of trading in securities on the New York Stock Exchange (“NYSE”) or there shall have been established by the NYSE, or by the Commission any general limitation on prices for such trading or any general restrictions on the distribution of securities, or a general banking moratorium declared by Federal, Missouri or New York state authorities or (b) there shall have occurred any (i) material outbreak or escalation of hostilities (including, without limitation, an act of terrorism) or (ii) declaration by the United States of war or national or international calamity or crisis, including, but not limited to, a material escalation of hostilities or a calamity that existed prior to the date of this Underwriting Agreement or (iii) material adverse change in the financial markets in the United States, and the effect of any such event specified in clause (a) or (b) above on the financial markets of the United States shall be such as to materially and adversely affect, in the reasonable judgment of the Underwriters, their ability to proceed with the public offering or the delivery of the Bonds on the terms and in the manner contemplated by the Final Prospectus. Any termination hereof pursuant to this Section 12 shall be without liability of any party to any other party except as otherwise provided in Sections 8(a)(vi) and 11 hereof.

- 29 -

13. Representations, Warranties and Covenants of the Underwriters. The Underwriters, severally and not jointly, represent, warrant and agree with the Issuer and Evergy Missouri West that, unless the Underwriters obtained, or will obtain, the prior written consent of the Issuer or Evergy Missouri West, the Underwriters (x) have not delivered, and will not deliver, any Rating Information (as defined below) to any Rating Agency until and unless the Issuer or Evergy Missouri West advises the Underwriters that such Rating Information is posted to password-protected website maintained by the Servicer pursuant to paragraph (a)(3)(iii)(B) of Rule 17g-5 under the Exchange Act in the same form as it will be provided to such Rating Agency, and (y) have not participated, and will not participate, with any Rating Agency in any oral communication of any Rating Information without the participation of a representative of the Issuer or Evergy Missouri West.

14. Absence of Fiduciary Relationship. Each of the Issuer and Evergy Missouri West acknowledges and agrees that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Issuer and Evergy Missouri West with respect to the offering of the Bonds contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Issuer or Evergy Missouri West. Additionally, none of the Underwriters is advising the Issuer or Evergy Missouri West as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Issuer and Evergy Missouri West shall consult with their own advisors concerning such matters and shall be responsible for making their own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to the Issuer or Evergy Missouri West with respect thereto. Any review by the Underwriters of the Issuer or Evergy Missouri West, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Issuer or Evergy Missouri West.

15. Notices. All communications hereunder will be in writing and may be given by United States mail, courier service, telecopy, telefax or facsimile (confirmed by telephone or in writing in the case of notice by telecopy, telefax or facsimile) or any other customary means of communication, and any such communication shall be effective when delivered, or if mailed, three days after deposit in the United States mail with proper postage for ordinary mail prepaid, and if sent to the Underwriters, to it at the address specified in Schedule I hereto; and if sent to Evergy Missouri West, to it at 1200 Main Street, Kansas City, Missouri 64105, Attention: Heather A.

16. Successors. This Underwriting Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and controlling persons referred to in Section 11 hereof, and no other person will have any legal or equitable right, remedy or claim under or with respect to this Underwriting Agreement or any provision herein contained.
