The Bond Registrar shall retain copies of all letters, notices and other written communications received pursuant to Section 1.05 of the Indenture or this Section 5 in accordance with its customary policy.

The Indenture Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Second Supplemental Indenture or under applicable law with respect to any registrations of transfer of any interest in any 2005 Series Bond (including any transfers between or among members of, or participants in, the Depositary or beneficial owners of interests in any Global Bond) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Second Supplemental Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

(d) A Global Bond may be transferred, in whole but not in part, only to another nominee of the Depositary, or to a successor Depositary selected or approved by the Owner Trustee or to a nominee of such successor Depositary.

(e) If at any time the Depositary notifies the Owner Trustee that it is unwilling or unable to continue as Depositary, and a successor Depositary for such series is not appointed by the Owner Trustee within 90 days after the Owner Trustee receives such notice, the Owner Trustee will execute, and, subject to Article Two of the Indenture, the Indenture Trustee, upon the written order of the Owner Trustee, will authenticate and make available for delivery the 2005 Series Bonds in definitive registered form without coupons, in authorized denominations, and in an aggregate principal amount equal to the principal amount of the Global Bond in exchange for the Global Bond. In addition, the Owner Trustee may at any time determine that the 2005 Series Bonds shall no longer be represented by a Global Bond.

Such Bonds in definitive registered form issued in exchange for the Global Bond shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Indenture Trustee. The Indenture Trustee shall deliver such Bonds to the Depositary for delivery to the Persons in whose names such Bonds are so registered.

[FORM OF REVERSE OF SECURED FACILITY BOND]

This Bond is one of an authorized issue of Bonds of the Owner Trustee known as its “Secured Facility Bonds, Refunding Series 2005” (herein called the “Bonds”) issued under, and all equally and ratably secured by, a Trust Indenture, Security Agreement and Mortgage (the “Original Indenture”) dated as of September 1, 1987, as supplemented by the First Supplemental Indenture ( the “First Supplemental Indenture”) dated as of September 29, 1992 and the Second Supplemental Indenture dated as of June 30, 2005 (the “Second Supplemental Indenture” and, collectively with the Original Indenture and the First Supplemental Indenture, the “Indenture”), among the Owner Trustee, Kansas Gas and Electric Company, a Kansas corporation (herein called “KGE”), and Deutsche Bank Trust Company Americas, a New York banking corporation, as Indenture Trustee (herein called the “Indenture Trustee”, which term includes any successor Indenture Trustee under the Indenture), to which Indenture and all indentures supplemental thereto, including the First Supplemental Indenture and Second Supplemental Indenture, reference is hereby made for a description of the nature and extent of the property assigned, pledged, transferred and mortgaged thereunder, the respective rights of the Holders of said Bonds and of the Indenture Trustee and the Owner Trustee in respect of such security, and the terms upon which said Bonds are to be authenticated and delivered. The Indenture permits the issuance of additional series of bonds for the purposes and as provided therein.

The principal of, premium (if any), interest and Additional Interest (if any) on this Bond are payable from, and secured by, the Indenture Estate and the income and proceeds received by the Indenture Trustee therefrom, and all payments of principal, premium (if any), interest and Additional Interest (if any) shall be made in accordance with the terms of the Indenture.

All payments of principal, premium (if any), interest and Additional Interest (if any) to be made hereunder and under the Indenture shall be made only from the Indenture Estate or the income and proceeds received by the Indenture Trustee therefrom, and all payments of principal, premium (if any), interest and Additional Interest (if any) shall be made in accordance with the terms of the Indenture. Each Holder hereof, by its acceptance of this Bond, agrees that (a) except as expressly provided in the Indenture, it will look solely to the Indenture Estate or the income and proceeds received by the Indenture Trustee therefrom to the extent available for distribution to the Holder hereof as provided in the Indenture and (b) neither the Owner Participant nor the Owner Trustee, in its individual capacity, nor the Indenture Trustee, in its individual capacity, is liable to the Holder hereof for any amounts payable under this Bond or the Indenture or, except as provided in the Indenture, for any liability under the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of KGE and the Owner Trustee and the rights of the Holders of the Bonds under the Indenture at any time by KGE and the Owner Trustee with the consent of the Holders of not

A-6

less than a majority in aggregate principal amount of the Bonds and all other series of bonds issued under the Indenture at the time Outstanding. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Bonds and all other series of bonds issued under the Indenture at the time Outstanding, on behalf of the Holders of all the Bonds and all the bonds of such other series, to waive compliance by KGE and the Owner Trustee with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Bond shall be conclusive and binding upon such Holder and upon all future Holders of this Bond and of any Bond issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this Bond.

The Bonds are limited in aggregate principal amount to $320,000,000.

In addition to the purchase rights described below and as more fully described in the Second Supplemental Indenture, the Bonds are subject to mandatory redemption, in whole but not in part, at 100% of the principal amount thereof together in each case with accrued and unpaid interest, if any, and Additional Interest, if any, to, but excluding, the Redemption Date, under any of the following circumstances:

(i) The receipt of payment of the applicable Casualty Value under the Lease upon the occurrence of an Event of Loss, unless, in connection with an Event of Loss described in clause (e) of the definition thereof, KGE assumes the Bonds then Outstanding pursuant to Section 2.16 of the Indenture; or

(ii) The receipt of payment of the applicable purchase price or Casualty Value resulting from a termination of the Lease pursuant to Section 7 thereof; or

(iii) The receipt of payment of the applicable purchase price or Casualty Value due upon an exercise by KGE of its option to purchase the Assets under subsection 6.1(c)(iii) of the Lease, unless in connection therewith KGE assumes the Bonds then Outstanding pursuant to Section 2.16 of the Indenture; or

(iv) The receipt of payment of the applicable purchase price or Casualty Value due upon the exercise by KGE of its option to purchase the Assets under subsection 6.1(c)(ii) of the Lease in connection with a required Nonseverable Alteration, as contemplated by Section 11.4 of the Lease, unless in connection therewith KGE assumes the Bonds then Outstanding pursuant to Section 2.16 of the Indenture.

The Bonds are also subject to mandatory redemption pursuant to sinking fund installments, as more fully provided in the Second Supplemental Indenture,

A-7

at 100% of the principal amount thereof, together with accrued and unpaid interest, if any, and Additional Interest, if any, to the Redemption Date, on the dates and in the respective principal amounts (before taking into account certain adjustments as indicated below) set forth in the following table:


Redemption Date	Amount of Sinking Fund Payment
September 29, 2007	$	5,393,751.27

March 29, 2020	$	32,253,612.93
March 29, 2021	$	18,842,425.15

In the event of any partial redemption of Bonds (other than pursuant to the aforementioned sinking fund), the principal amount of Bonds to be redeemed thereafter pursuant to the sinking fund schedule indicated above shall be proportionately reduced as provided in the Indenture.

Selection of the Bonds to be redeemed pursuant to each such sinking fund payment shall be performed using such method as the Indenture Trustee deems fair and appropriate.

The Bonds shall be subject to special mandatory redemption, in whole but not in part, at the applicable redemption prices set forth under Section 6.02(c) of the Indenture upon the receipt of payment of the applicable purchase price upon the exercise by KGE of its option to purchase the Assets on September 29, 2015 or September 29, 2020 under Section 6.l(c)(i) of the Lease or, in the case of a Nonseverable Alteration not required by Section 11.4 of the Lease, Section 6.1(c)(ii) of the Lease unless, in either case, KGE shall assume the 2005 Series Bonds then Outstanding pursuant to Section 2.16 of the Indenture.

The Bonds are subject to redemption at the option of the Owner Trustee, as a whole at any time and in part from time to time, as provided below:

(i) At any time from the date hereof to, but not including September 29, 2015, the Owner Trustee may redeem all or any portion of the Bonds then outstanding, after giving the required notice under the Indenture, at a redemption price equal to the greater of:

(a) 100% of the principal amount of the Bonds then outstanding, or

A-8

(b) the sum of the present values of the remaining scheduled payments of the principal amount of the Bonds then outstanding and interest thereon (exclusive of interest to the Redemption Date) discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 25 basis points,

plus, in either case, accrued and unpaid interest, if any, and Additional Interest, if any, to the Redemption Date (subject to the right of holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date).

(ii) On and after September 29, 2015, the Bonds shall be redeemable prior to Maturity at the option of the Owner Trustee, in whole or in part, at a Redemption Price equal to 100% of the principal amount thereof, together with accrued and unpaid interest, if any, and Additional Interest, if any, to, but excluding, the Redemption Date.

In the case of any redemption of Bonds, unpaid installments of interest maturing on or prior to the Redemption Date will be payable to the Holders of such Bonds of record at the close of business on the relevant regular or subsequent Record Date referred to on the face hereof.

In the event any of the Bonds are called for redemption, the Indenture Trustee shall give notice, in the name of the Owner Trustee, of the redemption of such Bonds. Notice of redemption of Bonds (including redemption through the operation of the sinking fund with respect to any series) shall be given by first—class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the date fixed for redemption, to each Holder of Bonds to be redeemed, at his address appearing on the Bond Register.

With respect to any notice of redemption of Bonds at the option of the Owner Trustee as described above, unless, upon the giving of such notice, such Bonds shall be deemed to have been paid within the meaning of the Indenture, such notice shall state that such redemption shall be conditional upon the receipt by the Indenture Trustee on or prior to the date fixed for such redemption of moneys sufficient to pay the principal of, premium, if any, interest and Additional Interest, if any, on such Bonds to be redeemed, and that, if such moneys shall not have been so received, said notice shall be of no force and effect and the Owner Trustee shall not be required to redeem such Bonds. In the event that such notice of redemption contains such a condition and such moneys are not so received, the redemption shall not be made and the Indenture Trustee shall within a reasonable time thereafter give notice, in the manner in which the notice of redemption was given, that such moneys were not so received.

A-9

If a notice of redemption shall be unconditional, or if the conditions of a conditional notice of redemption shall have been satisfied, then upon presentation and surrender of Bonds so called for redemption at the corporate trust office of the Paying Agent, such Bonds shall be redeemed.

The Indenture provides that Bonds of a denomination larger than $1,000 may be redeemed in part ($1,000 or an integral multiple thereof) and that upon any partial redemption of any such Bond the same may be surrendered at the corporate trust office of the Paying Agent in exchange for one or more new Bonds for the unredeemed portion thereof.

Bonds (or portions thereof as aforesaid) for whose redemption and payment provision is made in accordance with the Indenture shall thereupon cease to be entitled to the Lien of the Indenture and shall cease to bear interest from and after the date fixed for redemption.

If an Event of Default under the Indenture shall occur and be continuing, the principal of this Bond may, subject to certain rights of the Owner Trustee or the Owner Participant contained or referred to in the Indenture, become or be declared immediately due and payable, in the manner and with the effect provided in the Indenture.

Under certain circumstances, the Owner Trustee may make payments or perform obligations of KGE under the Indenture and the Lease. Exercise of the Owner Trustee’s limited right to cure would prevent the Indenture Trustee and the Holder hereof from exercising any remedies otherwise available under the Indenture as a result of KGE’s failure to make such payments or perform such obligations.

Following a declaration of acceleration of the Bonds, the Owner Trustee may, subject to the conditions specified in the Indenture, purchase all of the Bonds in accordance with the terms of the Indenture. Each Holder of this Bond, by accepting the same, agrees, subject to the provisions of the Indenture, that, upon payment to the Indenture Trustee of all amounts payable on the Bonds and upon satisfaction of all of the conditions contained in the Indenture pertaining to the purchase of Bonds by the Owner Trustee, such Holder shall be deemed to sell this Bond to the Owner Trustee.

The Lien upon the Indenture Estate is subject to being legally discharged prior to the Maturity of this Bond upon the deposit with the Indenture Trustee of money or certain obligations of the United States of America sufficient to pay the principal of, premium (if any), interest and Additional Interest (if any) on this Bond when due, all in accordance with the terms and conditions of the Indenture.

The Bond is transferable by the registered owner hereof in person or by attorney authorized in writing, at the corporate trust office of the Bond Registrar, Deutsche Bank Trust Company Americas (or if such office is not in the Borough

A-10

of Manhattan, The City of New York, at either such office or an office to be maintained in such Borough), upon surrender of this Bond, and, upon any such transfer, a new Bond of the same Stated Maturity of principal for the same aggregate principal amount will be issued to the transferee in exchange herefor.

The Bonds are issuable only as registered Bonds without coupons in denominations of $1,000 and any integral multiple thereof. As provided in, and subject to the provisions of, the Indenture, Bonds of a particular Stated Maturity of principal are exchangeable for other Bonds of such Stated Maturity of a different authorized denomination or denominations, as requested by the Holder surrendering the same.

No service charge will be made to any Holder of Bonds for any such transfer or exchange, but the Bond Registrar may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentation of this Bond for registration of transfer, the Person in whose name this Bond is registered shall be deemed to be the owner hereof for the purpose of receiving payment as herein provided and for all other purposes whether or not this Bond shall be overdue, regardless of any notice to anyone to the contrary.

As provided in the Indenture, the Indenture and the Bonds shall be governed by and construed in accordance with the laws of the State of New York without regard to the principles of conflicts of law thereof.
