(formerly Great Plains Energy Incorporated), 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. (formerly KCP&L Greater Missouri Operations Company), a Delaware corporation (the “Company”), entered into a Note Purchase Agreement dated as of August 16, 2013 (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.

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 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 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

1

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.

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

2

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, 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

3

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.

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.

4

(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 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.

(d)    The Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by the Note Agreement and that its agreements set forth in this Guaranty Agreement (including this Section 5) are knowingly made in contemplation of such benefits.

Section 6.    Reinstatement of Guaranty.
