SECOND AMENDMENT TO CREDIT AGREEMENT

This SECOND AMENDMENT TO CREDIT AGREEMENT (this “Second Amendment”), dated as of December 14, 2017, is entered into by and among WESTAR ENERGY, INC., a Kansas corporation (the “Borrower”), KANSAS GAS AND ELECTRIC COMPANY, a Kansas corporation (the “Guarantor”), the Lenders (as hereinafter defined) and WELLS FARGO BANK, NATIONAL ASSOCIATION, as administrative agent (in such capacity, the “Administrative Agent”).

A.    The Borrower, the several banks and other financial institutions from time to time party thereto (the “Lenders”), and the Administrative Agent are parties to that certain Credit Agreement, dated as of February 18, 2011 (as amended, restated, amended and restated, supplemented or otherwise modified from time to time prior to the date hereof, the “Credit Agreement”), pursuant to which the Lenders have made available a revolving credit facility to the Borrower in the aggregate principal amount of $270,000,000, which is set to mature and terminate on February 18, 2018. Capitalized terms used but not defined herein shall have the meanings assigned to such terms in the Credit Agreement, as amended by this Second Amendment.

B.    On July 9, 2017, Great Plains Energy Incorporated, a Missouri corporation (“Great Plains Energy”), and the Borrower entered into an Amended and Restated Agreement and Plan of Merger (the “Amended and Restated Merger Agreement”) among Great Plains Energy, the Borrower, Monarch Energy Holding, Inc., a Missouri corporation (“Holdco”), and King Energy, Inc., a Kansas corporation (“Merger Sub”), and for certain limited purposes, GP Star, Inc., a Kansas corporation and a wholly owned subsidiary of Great Plains Energy (“GP Star”). Holdco is a newly formed entity wholly owned by Great Plains Energy, and Merger Sub is a wholly owned subsidiary of Holdco, each of which was formed for the purpose of effecting the transactions contemplated by the Amended and Restated Merger Agreement. The Amended and Restated Merger Agreement is an amendment and restatement in its entirety of the Agreement and Plan of Merger (the “Original Merger Agreement”), dated as of May 29, 2016, among Great Plains Energy, the Borrower and GP Star. GP Star has withdrawn from the Original Merger Agreement and is only party to the Amended and Restated Merger Agreement for the purposes of withdrawing from the Original Merger Agreement. Pursuant to the Amended and Restated Merger Agreement, subject to the satisfaction or waiver of certain conditions, (i) Great Plains Energy will merge with and into Holdco (the “GPE Merger”), with Holdco continuing as the surviving corporation in the GPE Merger, and (ii) Merger Sub will merge with and into the Borrower (the “Westar Merger”, together with the GPE Merger, the “Mergers”), with the Borrower continuing as the surviving corporation in the Westar Merger. Following the Mergers, Holdco will be the direct parent of the Borrower and Great Plains Energy’s direct subsidiaries.

C.    The Borrower has requested (i) the consent of the Required Lenders to the Mergers, (ii) a one-year extension of the Revolving Termination Date to February 18, 2019 and (iii) certain amendments to the Credit Agreement and the other Loan Documents, in each case on the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the foregoing and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

Effective upon the Effective Date (as hereinafter defined), the Credit Agreement is hereby amended as follows:

Pursuant to Section 2.1(b) of the Credit Agreement, the Borrower has requested an extension of the existing Revolving Termination Date for a period of one year from February 18, 2018 to February 18, 2019. As of the date hereof, Extending Lenders holding more than fifty percent (50%) of the Total Revolving Commitments have agreed to the extension (such agreement evidenced by their execution and delivery of a counterpart of this Agreement) and, subject to the satisfaction of the conditions in Article III hereof, the Revolving Termination Date as to the Extending Lenders shall be extended to February 18, 2019. Subject to the right of the Borrower to accept commitments from New Lenders pursuant to Section 2.1(b) of the Credit Agreement to replace the Revolving Commitment of any Declining Lenders for the remaining duration of the Credit Agreement, the Revolving Termination Date as to the Declining Lenders, if any, remains February 18, 2018.

3.1    The amendments set forth in Article I, the extension of the Revolving Termination Date set forth in Article II and the limited consent set forth in Article VI shall become effective as of the date (the “Effective Date”) when, and only when, each of the following conditions precedent shall have been satisfied:

The Borrower hereby represents and warrants to the Administrative Agent and the Lenders that (i) each of the representations and warranties contained in Section 3 of the Credit Agreement, if not qualified as to materiality, are true and correct in all material respects and all other representations and warranties set forth in Section 3 of the Credit Agreement are true and correct, in each case on and as of the Effective Date, both immediately before and after giving effect to this Second Amendment (except for those representations and warranties or parts thereof that, by their terms, expressly relate solely to a specific date, in which case such representations and warranties, if not qualified as to materiality, shall be true and correct in all material respects and all such other representations and warranties shall be true and correct, in each case as of such specific date), (ii) this Second Amendment has been duly authorized, executed and delivered by the Borrower and constitutes the legal, valid and binding obligation of the Borrower enforceable against it in accordance with its terms and (iii) no Default or Event of Default shall have occurred and be continuing on the Effective Date, both immediately before and after giving effect to this Second Amendment. The Borrower further represents and warrants that there have been no amendments, modifications, supplements, waivers or consents to the Amended and Restated Merger Agreement (including all schedules and exhibits thereto) since July 9, 2017 that are materially adverse to the interests of the Lenders.

Each of the Borrower and the Guarantor hereby confirms and agrees that after giving effect to this Second Amendment, the Credit Agreement and the other Loan Documents remain in full force and effect and enforceable against it in accordance with their respective terms and shall not be discharged, diminished, limited or otherwise affected in any respect. Each of the Borrower and the Guarantor represents and warrants to the Lenders that it has no knowledge of any claims, counterclaims, offsets, or defenses to or with respect to its obligations under the Loan Documents, or if the Borrower or the Guarantor has any such claims, counterclaims, offsets, or defenses to the Loan Documents or any transaction related to the Loan Documents, the same are hereby waived, relinquished, and released in consideration of the execution of this Second Amendment. This acknowledgment and confirmation by the Borrower and the Guarantor is made and delivered to induce the Administrative Agent and the Lenders to enter into this Second Amendment. Each of the Borrower and Guarantor acknowledges that the Administrative Agent and the Lenders would not enter into this Second Amendment in the absence of the acknowledgment and confirmation contained herein.

6.2    Upon the occurrence of any Consent Termination Event, (i) the limited consent set forth in Section 6.1 hereof shall automatically terminate and be of no further force or effect, (ii) all rights and remedies with respect to the matters set forth in Section 6.1 hereof of the Administrative Agent and the Lenders under the Credit Agreement and any other Loan Document shall, without any further action by any person, automatically be reinstated as if the limited consent set forth in Section 6.1 hereof had not become effective and (iii) clause (ii) of the definition of “Change of Control” (as amended by this Second Amendment) shall be deleted and given no further force or effect.
