The Company further covenants and agrees to and with the Trustees and their successors in said trust under the Mortgage, as follows:

ARTICLE I
2016 SERIES OF BONDS 
SECTION 1.There shall be a series of bonds designated “2.75% Series due 2016” (herein sometimes referred to as the “Bonds of the 2016 Series”), each of which shall also bear the descriptive title, First Mortgage Bond, and the form thereof, which is established by Resolution of the Board of Directors of the Company, shall contain suitable provisions with respect to the matters hereinafter in this Article I specified.  Bonds of the 2016 Series shall be limited to $270,000,000 in aggregate principal amount, except as provided in Section 16 of the Mortgage, shall mature on February 18, 2016, and shall be issued as fully registered bonds in denominations of Five Thousand Dollars and in any multiple or multiples of Five Thousand Dollars.  Bonds of the 2016 Series shall bear interest at the rate of 2.75% per annum payable (subject to the second paragraph of Section 4) on the interest payment dates for the Loans (as defined below).  Every Bond of the 2016 Series shall bear interest from each interest payment date for the Loans next preceding the date thereof, unless no interest has been paid on the Bond in which case from February 12, 2013.  The principal of and interest on Bonds of the 2016 Series shall be payable at the office or agency of the Company in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for public and private debts.
SECTION 2.  Bonds of the 2016 Series shall be dated as in Section 10 of the Mortgage provided. 
SECTION 3.  Bonds of the 2016 Series are redeemable prior to maturity only upon demand therefor by the Collateral Agent.  To effect the redemption of Bonds of the 2016 Series, the Collateral Agent shall deliver to the Trustee (and deliver a copy thereof to the Company) a written demand (hereinafter referred to as a “Redemption Demand”) for the redemption of Bonds of the 2016 Series, signed by an authorized officer and dated the date of its delivery to the Corporate Trustee, stating (i) that an Event of Default (as defined in the Collateral Agreement and as defined in the Credit Agreement referred to below) has occurred and is continuing, (ii) that there are not sufficient 

available funds held by the Collateral Agent pursuant to the Collateral Agreement to make all payments required as a result of such Event of Default, (iii) the amount of funds, in addition to available funds held by the Collateral Agent pursuant to the Collateral Agreement, required to make such payments, and (iv) the principal amount of Bonds of the 2016 Series the Collateral Agent demands to have redeemed and the redemption date therefor which date should be at least thirty-one (31) days after the date of such Redemption Demand (provided, such principal amount shall not exceed the amount of funds specified pursuant to the foregoing clause (iii)).  The Trustee may conclusively presume the statements contained in the Redemption Demand to be correct.  Redemption of Bonds of the 2016 Series shall in all cases be at a price equal to the principal amount of the Bonds to be redeemed together with accrued interest to the redemption date, and such amount shall become and be due and payable on the redemption date.
The Company hereby covenants that if a Redemption Demand shall be delivered to the Corporate Trustee, the Company will deposit, on or before the redemption date, with the Corporate Trustee, in accordance with Article X of the Mortgage, an amount in cash sufficient to redeem the Bonds of the 2016 Series so called for redemption.
SECTION 4.  All Bonds of the 2016 Series shall be issued and pledged by the Company to the Collateral Agent pursuant to a Collateral and Guarantee Agreement dated as of February 18, 2011 among the Company, Westar Energy, Inc. (“WEI”) and Wells Fargo Bank, National Association (in such capacity, the “Collateral Agent”) (the “Collateral Agreement”) to secure the payment of the principal of, and up to 2.75% per annum of the interest on any of the loans issued pursuant to the $270,000,000 Credit Agreement, dated as of February 18, 2011, among WEI, Wells Fargo Bank, National Association, as administrative agent, the other agents party thereto, and the lenders party thereto (the “Credit Agreement” and the loans thereunder are referred to collectively as the “Loans”).

The obligation of the Company to make payments with respect to the principal of and interest on Bonds of the 2016 Series (including without limitation upon maturity thereof) shall be fully or partially, as the case may be, satisfied and discharged to the extent that, at the time that any such payment shall be due, the then due principal of and interest on the Loans shall have been fully or partially paid, or there shall be held by the Collateral Agent pursuant to the Collateral Agreement sufficient available funds to fully or partially pay the then due principal of and interest on the Loans.  Notwithstanding any other provisions of this Supplemental Indenture or the Mortgage, interest on the Bonds of the 2016 Series shall be deemed fully or partially satisfied and discharged as provided herein even if the interest rate on Bonds of the 2016 Series may be higher or lower than the interest rate on any of the Loans at the time interest on any such Loans is paid.  The Corporate Trustee may conclusively presume that the obligation of the Company to make payments with respect to the principal of and interest on Bonds of the 2016 Series shall have been fully satisfied and discharged unless and until the Corporate Trustee shall have received a written notice from the Collateral Agent, signed by an authorized officer, stating (i) that timely payment of the principal of or interest on the Loans required to be made by the Company has not been made, (ii) that there are not sufficient available funds held by the Collateral Agent pursuant to the Collateral Agreement to make such payment and (iii) the amount of funds, in addition to available funds held by the Collateral Agent pursuant to the Collateral Agreement, required to make such payment.
SECTION 5.  At the option of the registered owner, any Bonds of the 2016 Series, upon surrender thereof, for cancellation, at the office or agency of the Company in the Borough of Manhattan, City of New York, shall be exchangeable for a like aggregate principal amount of bonds of the same series of other authorized denominations.  The Bonds of the 2016 Series may bear such 

legends as may be necessary to comply with any law or with any rules or regulations made pursuant thereto or with the rules or regulations of any stock exchange or to conform to usage with respect thereto. 
SECTION 6.  Bonds of the 2016 Series shall be transferable upon the surrender thereof, for cancellation together with a written instrument of transfer in form approved by the registrar duly executed by the registered owner or by his duly authorized attorney, at the office or agency of the Company in the Borough of Manhattan, City of New York. 
SECTION 7.  The Company may deliver to the Trustee in substitution for any Bonds of the 2016 Series, mortgage bonds or other similar instruments of the Company or any successor entity, whether by merger, combination or acquisition of all or substantially all of the assets of the Company, or otherwise, issued under a mortgage and deed of trust or similar instrument of the Company or any successor entity in like principal amount of like term and bearing the same rate of interest as the Bonds of the 2016 Series.

Each of the Borrower and 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 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 Agreement.  This acknowledgment and confirmation by the Borrower and Guarantor is made and delivered to induce the Administrative Agent and the Lenders to enter into this Agreement.
