On May 15, 2008, Kansas Gas and Electric Company (“KGE”), our wholly-owned subsidiary, entered into a Bond Purchase Agreement (the “Agreement”) with several purchasers identified in the Agreement (“Purchasers”). Under the terms of the Agreement, on May 15, 2008, KGE completed the sale to the Purchasers of $150,000,000 aggregate principal amount of First Mortgage Bonds consisting of (a) $50,000,000 aggregate principal amount of First Mortgage Bonds, 6.15% Series A Due May 15, 2023 and (b) $100,000,000 aggregate principal amount of First Mortgage Bonds, 6.64% Series B Due May 15, 2038 (collectively, the “Bonds”). The Bonds were issued under KGE’s Mortgage and Deed of Trust, dated as of April 1, 1940, as amended.

KGE will pay interest on the bonds on May 15 and November 15 of each year until maturity, beginning on November 15, 2008. KGE may redeem the bonds, in whole or in part, at any time at a redemption price equal to 100% of the principal amount to be redeemed plus accrued and unpaid interest of the principal amount being redeemed to the redemption date plus a make-whole amount as described in the Fifty-First Supplemental Indenture dated as of May 15, 2008 (the “Supplemental Indenture”). The Bonds will be secured equally with all other bonds outstanding or hereafter issued under KGE’s Mortgage and Deed of Trust, dated as of April 1, 1940, as supplemented and amended.

The sale of the Bonds is being made by KGE in reliance on a private placement exemption from registration under the Securities Act of 1933, as amended.

The foregoing summary is qualified in its entirety by reference to the text of the Agreement and the Supplemental Indenture, a copy of each of which is filed as an exhibit hereto and is incorporated by reference.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.

KANSAS GAS AND ELECTRIC COMPANY, a Kansas corporation (the “Company”), agrees with the Purchasers listed in the attached Schedule A (the ‘Purchasers”) to this Bond Purchase Agreement (this “Agreement”) as follows:

Section 1.1. Authorization of the Bonds. The Company has authorized the issue and sale of $150,000,000 aggregate principal amount of its First Mortgage Bonds consisting of (a) $50,000,000 aggregate principal amount of its First Mortgage Bonds, 6.15% Series A Due May 15, 2023 (the “Series A Bonds”) and (b) $100,000,000 aggregate principal amount of its First Mortgage Bonds, 6.64% Series B Due May 15, 2038 (the “Series B Bonds”). The Series A Bonds and the Series B Bonds are herein collectively referred to as the “Bonds”. The term “Bonds” shall include any such bonds issued in substitution therefor pursuant to the terms and provisions of the Supplemental Indenture (as hereinafter defined) and the Indenture (as hereinafter defined). The Series A Bonds and the Series B Bonds shall be substantially in the form set out in the Supplemental Indenture, with such changes therefrom, if any, as may be approved by the Purchasers and the Company. Certain capitalized and other terms used in this Agreement are defined in Schedule B to this Agreement; and references to a “Schedule” or an “Exhibit” are, unless otherwise specified, to a Schedule or an Exhibit attached to this Agreement.

Subject to the terms and conditions of this Agreement, the Company will issue and sell to each Purchaser and each Purchaser will purchase from the Company, at the Closing provided for in Section 3, Bonds in the principal amount specified opposite such Purchaser’s name in Schedule A at the purchase price of 100% of the principal amount thereof. The obligations of each Purchaser hereunder are several and not joint obligations and no Purchaser shall have any obligation or any liability to any Person for the performance or non-performance of any other Purchaser hereunder.

Section 2.2. Security for the Bonds. The Bonds are to be issued under and in accordance with a Supplemental Indenture dated on or about May 15, 2008 (the “Supplemental Indenture”) between the Company and The Bank of New York Trust Company, N.A., a national banking association, as successor corporate trustee to Guaranty Trust Company of New York (together with any successors and assigns in such capacity, the “Corporate Trustee”) and Judith L. Bartolini, an individual, in her capacity as successor individual trustee (together with any successors and assigns in such capacity, the “Individual Trustee” and, together with the Corporate Trustee, the “Trustees”), which shall be substantially in the form attached hereto as Exhibit A. The Supplemental Indenture is a supplement to the Mortgage and Deed of Trust dated as of April 1, 1940 between the Company (as successor by merger to Kansas Gas and Electric Company, a West Virginia corporation) and the Corporate Trustee, as the successor corporate trustee thereunder, and the Individual Trustee, as the successor individual trustee thereunder, as heretofore amended and supplemented by fifty supplemental indentures thereto (the “Indenture”; and the Indenture as amended and supplemented by the Supplemental Indenture, the “Amended Indenture”).

No labor problem or dispute with the employees of the Company exists or, to the knowledge of the Company, is threatened or imminent, and the Company is not aware of any existing or imminent labor disturbance by the employees of any of its principal suppliers, contractors or customers, that would reasonably be expected to have a Material Adverse Effect.

Section 5.20. Perfection of Liens. The Indenture has been duly recorded and filed, and, on the date of the Closing, the Amended Indenture will have been duly recorded and filed, in each place in which such recording or filing is required to protect and preserve the Lien of the Indenture and the Amended Indenture, as the case may be, and all taxes and recording or filing fees required to be paid in connection with the execution, recording or filing of the Indenture and Amended Indenture have been or will have been duly paid, as the case may be.

Section 6.1. Purchase for Investment. Each Purchaser represents that it is an institutional “accredited investor” (as such term is defined under Rule 501(a)(1), (2), (3) or (7) promulgated under the Securities Act) and that such Purchaser is purchasing the Bonds for its own account or for the account of another Institutional Investor and not with a view to the distribution thereof, provided that the disposition of such Purchaser’s or such other Institutional Investor’s property shall at all times be within such Person’s control. Each Purchaser understands that the sale of the Bonds is being made by the Company in reliance on a private placement exemption from registration under the Securities Act and the Bonds may be resold only if registered pursuant to the provisions of the Securities Act or if an exemption from

registration is available, except under circumstances where neither such registration nor such an exemption is required by law, and that the Company is not required to register the Bonds under the Securities Act or to list the Bonds on any national securities exchange.

Section 6.2. Additional Representations of the Purchasers. Each Purchaser further represents that it (a) has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of its prospective investment in the Bonds, (b) has conducted its own investigation of the Company and the terms of the Bonds, (c) has had access to Westar Energy’s public filings with the SEC and to such financial and other information as it deems necessary to make its decision to purchase the Bonds, (d) has been offered the opportunity to ask questions of the Company and received answers thereto, all as such Purchaser deems necessary in connection with its decision to purchase the Bonds and (e) has the ability to bear the economic risks of such Purchaser’s prospective investment and can afford the complete loss of such investment.

Section 6.3. Legend. Each Purchaser understands that the Bonds will bear a legend substantially to the following effect:

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 OR THE SECURITIES LAWS OF ANY OTHER STATE OR OTHER JURISDICTION. NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, SUCH REGISTRATION.

Section 6.4. Source of Funds. Each Purchaser severally represents that at least one of the following statements is an accurate representation as to each source of funds (a “Source”) to be used by such Purchaser to pay the purchase price of the Bonds to be purchased by such Purchaser hereunder:

(a) the Source is an “insurance company general account” (as the term is defined in the United States Department of Labor’s Prohibited Transaction Exemption (“PTE”) 95-60) in respect of which the reserves and liabilities (as defined by the annual statement for life insurance companies approved by the National Association of Insurance Commissioners (the “NAIC Annual Statement”)) for the general account contract(s) held by or on behalf of any employee benefit plan together with the amount of the reserves and liabilities for the general account contract(s) held by or on behalf of any other employee benefit plans maintained by the same employer (or affiliate thereof as defined in PTE 95-60) or by the same employee organization in the general account do not exceed 10% of the total reserves and liabilities of the general account (exclusive of separate account liabilities) plus surplus as set forth in the NAIC Annual Statement filed with such Purchaser’s state of domicile; or

(b) the Source is a separate account that is maintained solely in connection with such Purchaser’s fixed contractual obligations under which the amounts payable, or credited, to any employee benefit plan (or its related trust) that has any interest in such separate account (or to any participant or beneficiary of such plan (including any annuitant)) are not affected in any manner by the investment performance of the separate account; or

(c) the Source is either (1) an insurance company pooled separate account, within the meaning of PTE 90-1 or (2) a bank collective investment fund, within the meaning of the PTE 91-38 and, except as disclosed by such Purchaser to the Company in writing pursuant to this clause (c), no employee benefit plan or group of plans maintained by the same employer or employee organization beneficially owns more than 10% of all assets allocated to such pooled separate account or collective investment fund; or

(d) the Source constitutes assets of an “investment fund” (within the meaning of Part V of PTE 84-14 (the “QPAM Exemption”)) managed by a “qualified professional asset manager” or “QPAM” (within the meaning of Part V of the QPAM Exemption), no employee benefit plan’s assets that are included in such investment fund, when combined with the assets of all other employee benefit plans established or maintained by the same employer or by an affiliate (within the meaning of Section V(c)(1) of the QPAM Exemption) of such employer or by the same employee organization and managed by such QPAM, exceed 20% of the total client assets managed by such QPAM, the conditions of Part I(c) and (g) of the QPAM Exemption are satisfied, neither the QPAM nor a Person controlling or controlled by the QPAM (applying the definition of “control” in Section V(e) of the QPAM Exemption) owns a 5% or more interest in the Company and (1) the identity of such QPAM and (2) the names of all employee benefit plans whose assets are included in such investment fund have been disclosed to the Company in writing pursuant to this clause (d); or

(e) the Source constitutes assets of a “plan(s)” (within the meaning of Section IV of PTE 96-23 (the “INHAM Exemption”)) managed by an “in-house asset manager” or “INHAM” (within the meaning of Part IV of the INHAM Exemption), the conditions of Part I(a), (g) and (h) of the INHAM Exemption are satisfied, neither the INHAM nor a Person controlling or controlled by the INHAM (applying the definition of “control” in Section IV(d) of the INHAM Exemption) owns a 5% or more interest in the Company and (1) the identity of such INHAM and (2) the name(s) of the employee benefit plan(s) whose assets constitute the Source have been disclosed to the Company in writing pursuant to this clause (e); or

(g) the Source is one or more employee benefit plans, or a separate account or trust fund comprised of one or more employee benefit plans, each of which has been identified to the Company in writing pursuant to this clause (g); or

(h) the Source does not include assets of any employee benefit plan, other than a plan exempt from the coverage of ERISA.

As used in this Section 6.4, the terms “employee benefit plan,” “governmental plan,” and “separate account” shall have the respective meanings assigned to such terms in Section 3 of ERISA.

Section 6.5. Acknowledgment. Each Purchaser understands that the Company will rely upon the truth and accuracy of the foregoing representations and agreements. If any Purchaser is

acquiring Bonds as a fiduciary or agent for one or more investor accounts, such Purchaser represents that it has sole investment discretion with respect to each such account and that it has full power to make the foregoing representations and agreements on behalf of such account.

Section 7.1. Financial and Business Information. The Company shall deliver to each holder of Bonds that is an Institutional Investor:

(a) Quarterly Statements — within 60 days after the end of each quarterly fiscal period in each fiscal year of the Company (other than the last quarterly fiscal period of each such fiscal year), copies of

(2) statements of income, changes in shareholders’ equity and cash flows of the Company, for such quarter and (in the case of the second and third quarters) for the portion of the fiscal year ending with such quarter,

setting forth in each case in comparative form the figures for the corresponding periods in the previous fiscal year, all in reasonable detail, prepared in accordance with GAAP applicable to quarterly financial statements generally, and certified by a Senior Financial Officer as fairly presenting, in all material respects, the financial position of the Company and the results of its operations and cash flows, subject to changes resulting from year-end adjustments, provided, in the event the Company becomes a “reporting issuer” under the Exchange Act, that delivery within the time period specified above of copies of the Company’s Quarterly Report on Form 10-Q prepared in compliance with the requirements therefor and filed with the SEC shall be deemed to satisfy the requirements of this Section 7.1(a), provided, further, that the Company shall be deemed to have made such delivery of such Quarterly Report on Form 10-Q if it shall have timely made such Quarterly Report on Form 10-Q available on “EDGAR” (such availability thereof being referred to as “Electronic Delivery”);

(b) Annual Statements — within 105 days after the end of each fiscal year of the Company, copies of

(2) statements of income, changes in shareholders’ equity and cash flows of the Company for such year,

setting forth in each case in comparative form the figures for the previous fiscal year, all in reasonable detail, prepared in accordance with GAAP, and accompanied by an opinion thereon of independent public accountants of recognized national standing, which opinion shall state that such financial statements present fairly, in all material respects, the financial position of the Company and the results of its operations and cash flows and have been prepared in conformity with GAAP, and that the examination of such accountants in connection with such financial statements has been made in accordance

with generally accepted accounting standards, and that such audit provides a reasonable basis for such opinion in the circumstances; provided, in the event the Company becomes a “reporting issuer” under the Exchange Act, that the delivery within the time period specified above of the Company’s Annual Report on Form 10-K for such fiscal year (together with the Company’s annual report to shareholders, if any, prepared pursuant to Rule 14a-3 under the Exchange Act) prepared in accordance with the requirements therefor and filed with the SEC shall be deemed to satisfy the requirements of this Section 7.1(b), provided, further, that the Company shall be deemed to have made such delivery of such Annual Report on Form 10-K and annual report if it shall have timely made Electronic Delivery thereof; and

(c) Requested Information — with reasonable promptness, such other data and information relating to the financial condition of the Company or the ability of the Company to perform its obligations hereunder, under the Bonds and under the other Bond Documents as any such holder of Bonds may from time to time reasonably request or such information regarding the Company required to satisfy the requirements of 17 C.F.R. §230.144A, as amended from time to time, in connection with any contemplated transfer of Bonds.

If the Company shall have one or more Subsidiaries during any fiscal period for which financial statements are being delivered pursuant to sub-paragraphs (a) or (b) of this Section 7.1, each of the financial statements described in such sub-paragraphs shall be deemed to refer to the consolidated financial statements of the Company and such Subsidiaries.

Section 7.2. Financial Information of Westar Energy. If at any time while any Bonds are outstanding (a) Westar Energy shall not be a “reporting issuer” under the Exchange Act, (b) no series of first mortgage bonds or any other debt securities of the Company are then rated by a nationally recognized statistical ratings organization and (c) Westar Energy is an Affiliate of the Company, then, within the respective periods provided in Section 7.1(a) and (b) above, the Company shall deliver or cause to be delivered to each holder of Bonds that is an Institutional Investor, financial statements of the character and for the dates and periods as in said Sections 7.1(a) and (b) of Westar Energy.

Section 7.3. Visitation. The Company shall permit the representatives of each holder of Bonds that is an Institutional Investor:

(a) No Default — if no Default or Event of Default then exists, at the expense of such holder and upon reasonable prior notice to the Company, but no more than two times during any 12-month period, to visit, during normal business hours, the principal executive office of the Company, to discuss the affairs, finances and accounts of the Company and its Subsidiaries with the Company’s officers, and (with the consent of the Company, which consent will not be unreasonably withheld) its independent public accountants, and (with the consent of the Company, which consent will not be unreasonably withheld) to visit the other offices and properties of the Company and each Subsidiary; and

(b) Default — if a Default or Event of Default then exists, at the expense of the Company and upon reasonable prior notice to the Company, to visit and inspect, during normal business hours, any of the offices or properties of the Company or any Subsidiary, to examine all their respective books of account, records, reports and other papers, to make copies and extracts therefrom, and to discuss their respective affairs, finances and accounts with their respective officers and independent public accountants (and by this provision the Company authorizes said accountants to discuss the affairs, finances and accounts of the Company and its Subsidiaries), all as often as may be requested.

Section 8.1. Place of Payments. Subject to Section 8.2, payments of principal of, and premium, if any, and interest becoming due and payable on, the Bonds shall be made in accordance with the terms and provisions of the Supplemental Indenture and the Indenture.

Section 8.2. Home Office Payment. So long as any Purchaser or its nominee shall be the holder of any Bond, and notwithstanding anything contained in Section 8.1 or any other Bond Document to the contrary, the Company will (or will cause its agent to) pay all sums becoming due with respect to such Bond (including, without limitation, for principal, premium, if any, and interest) by the method and at the address specified for such purpose for such Purchaser in Schedule A, or by such other method or at such other address as such Purchaser shall have from time to time specified to the Company in writing for such purpose, without the presentation or surrender of such Bond or the making of any notation thereon, except that upon written request of the Company made concurrently with or reasonably promptly after payment or redemption in full of any Bond, such Purchaser shall surrender such Bond for cancellation, reasonably promptly after any such request, to the Company at its principal executive office or to the Corporate Trustee at its principal corporate trust office. Prior to any sale or other disposition of any Bond held by any Purchaser or its nominee such Person will, at its election, either endorse thereon the amount of principal paid thereon and the last date to which interest has been paid thereon or surrender such Bond to the Company or the Corporate Trustee in exchange for a new Bond or Bonds of the same series pursuant to the terms of the Indenture. The Company will afford the benefits of this Section 8.2 to any Institutional Investor that is the direct or indirect transferee of any Bond purchased by any Purchaser under the Supplemental Indenture and this Agreement and has made the same agreement relating to such Bond as such Purchaser has made in this Section 8.2.

Section 9.1. Transaction Expenses. Whether or not the transactions contemplated hereby are consummated, the Company will pay all costs and expenses (including reasonable attorneys’ fees of a special counsel and, if reasonably required by the Required Holders, one local or other counsel, but excluding the allocated overhead of any internal counsel) incurred by each Purchaser and each other holder of Bonds in connection with such transactions and in connection with any amendments, waivers or consents under or in respect of this Agreement or any other Bond Document (whether or not such amendment, waiver or consent becomes effective). Notwithstanding the foregoing, in connection with the Closing, the Company will be

required only to pay the attorneys’ fees of a single special counsel acting for all Purchasers. The Company will pay, and will save each Purchaser and each other holder of Bonds harmless from, all claims in respect of any fees, costs or expenses, if any, of brokers and finders (other than those, if any, retained by such Person in connection with its purchase of the Bonds). The Company agrees to save harmless and indemnify each Purchaser and each other holder of Bonds from and against any liability resulting from the failure to reimburse such Person for any required documentary stamps, recordation and transfer taxes, recording costs, or any other expenses incurred by such Person in connection with this Agreement which are required by the terms of this Agreement to be paid or reimbursed by the Company.

Section 9.2. Survival. The obligations of the Company under this Section 9 will survive the payment or transfer of any Bond, the enforcement, amendment or waiver of any provision of this Agreement, the Bonds or any other Bond Document, and the termination of this Agreement.

All representations and warranties contained herein shall survive the execution and delivery of this Agreement, the Bonds and the other Bond Documents, the purchase or transfer by any Purchaser of any Bond or portion thereof or interest therein and the payment of any Bond, and may be relied upon by any subsequent holder of Bonds, regardless of any investigation made at any time by or on behalf of any Purchaser or any other holder of Bonds. All statements contained in any certificate or other instrument delivered by or on behalf of the Company pursuant to this Agreement or the other Bond Documents shall be deemed representations and warranties of the Company under this Agreement. Subject to the preceding sentence, this Agreement, the Bonds and the other Bond Documents embody the entire agreement and understanding between each Purchaser and the Company and supersede all prior agreements and understandings relating to the subject matter hereof.

Section 11.1. Requirements. This Agreement may be amended, and the observance of any term hereof may be waived (either retroactively or prospectively), with (and only with) the written consent of the Company and the Required Holders, except that (a) no amendment or waiver of any of the provisions of Section 1, 2, 3, 4, 5 or 6 hereof, or any defined term (as it is used therein), will be effective as to any holder of Bonds unless consented to by such holder in writing and (b) no such amendment or waiver may, without the written consent of the holder of each Bond at the time outstanding affected thereby amend any of Sections 11 or 14.

(a) Solicitation. The Company will provide each holder of Bonds (irrespective of the amount of Bonds then owned by it) with sufficient information, sufficiently far in advance of the date a decision is required, to enable such holder to make an informed and considered decision with respect to any proposed amendment, waiver or consent in respect of any of the provisions hereof or of any other Bond Document. The Company will deliver executed or true and correct copies of each amendment, waiver or consent effected pursuant to

the provisions of this Section 11 to each holder of outstanding Bonds promptly following the date on which it is executed and delivered by, or receives the consent or approval of, the requisite holders of Bonds.

(b) Payment. The Company will not directly or indirectly pay or cause to be paid any remuneration, whether by way of supplemental or additional interest, fee or otherwise, or grant any security or provide other credit support, to any holder of Bonds as consideration for or as an inducement to the entering into by any holder of Bonds of any waiver or amendment of any of the terms and provisions hereof or of the Supplemental Indenture unless such remuneration is concurrently paid, or security is concurrently granted or other credit support concurrently provided, on the same terms, ratably to each holder of Bonds then outstanding even if such holder did not consent to such waiver or amendment.

Section 11.3. Binding Effect, Etc. Any amendment or waiver consented to as provided in this Section 11 applies equally to all holders of Bonds and is binding upon them and upon each future holder of any Bond and upon the Company without regard to whether such Bond has been marked to indicate such amendment or waiver. No such amendment or waiver will extend to or affect any obligation, covenant, agreement, Default or Event of Default not expressly amended or waived or impair any right consequent thereon. No course of dealing between the Company and the holder of any Bond nor any delay in exercising any rights hereunder or under any Bond shall operate as a waiver of any rights of any holder of such Bond. As used herein, the term “this Agreement” and references thereto shall mean this Agreement as it may from time to time be amended or supplemented.

Section 11.4. Bonds Held by Company, Etc. Solely for the purpose of determining whether the holders of the requisite percentage of the aggregate principal amount of Bonds then outstanding approved or consented to any amendment, waiver or consent to be given under this Agreement or the Bonds, or have directed the taking of any action provided herein or in the Bonds to be taken upon the direction of the holders of a specified percentage of the aggregate principal amount of Bonds then outstanding, Bonds directly or indirectly owned by the Company or any of its Affiliates shall be deemed not to be outstanding.

All notices and communications provided for hereunder shall be in writing and sent (a) by telecopy if the sender on the same day sends a confirming copy of such notice by a recognized overnight delivery service (charges prepaid), (b) by registered or certified mail with return receipt requested (postage prepaid) or (c) by a recognized overnight delivery service (charges prepaid). Any such notice must be sent:

(1) if to any Purchaser or its nominee, to such Purchaser or its nominee at the address specified for such communications on Schedule A, or at such other address as such Purchaser or its nominee shall have specified to the Company in writing,

(2) if to any other holder of any Bond, to such holder at such address as such other holder shall have specified to the Company in writing, or

(3) if to the Company, to the Company to the attention of Larry D. Irick, General Counsel, c/o Westar Energy, Inc., 818 South Kansas Avenue, Topeka, KS 66612 1203, with a copy to Davis Polk & Wardwell, 1600 El Camino Real, Menlo Park, CA 94025, Attention: Daniel G. Kelly, Jr. or at such other address as the Company shall have specified to the holder of each Bond in writing.

This Agreement and all documents relating hereto, including, without limitation, (a) consents, waivers and modifications that may hereafter be executed, (b) documents received by any Purchaser at the Closing (except the Bonds themselves) and (c) financial statements, certificates and other information previously or hereafter furnished to any holder of Bonds, may be reproduced by any Person who is a party to or recipient of any such document by any photographic, photostatic, electronic, digital or other similar process and such Person may destroy any original document so reproduced. The Company and each Purchaser agree and stipulate that, to the extent permitted by applicable law, any such reproduction shall be admissible in evidence as the original itself in any judicial or administrative proceeding (whether or not the original is in existence and whether or not such reproduction was made by such Person in the regular course of business) and any enlargement, facsimile or further reproduction of such reproduction shall likewise be admissible in evidence. This Section 13 shall not prohibit the Company, any Purchaser or any other holder of Bonds from contesting any such reproduction to the same extent that it could contest the original, or from introducing evidence to demonstrate the inaccuracy of any such reproduction.

For the purposes of this Section 14, “Confidential Information” means information delivered to any Purchaser by or on behalf of the Company in connection with the transactions contemplated by or otherwise pursuant to this Agreement that is proprietary in nature and that was clearly marked or labeled or otherwise adequately identified when received by such Purchaser as being confidential information of the Company, provided that such term does not include information that (a) was publicly known or otherwise known to such Purchaser prior to the time of such disclosure, (b) subsequently becomes publicly known through no act or omission by such Purchaser or any Person acting on such Purchaser’s behalf, (c) otherwise becomes known to such Purchaser other than through disclosure by the Company or (d) constitutes financial statements delivered to such Purchaser that are otherwise publicly available. Each Purchaser agrees to maintain the confidentiality of such Confidential Information in accordance with procedures adopted by such Purchaser in good faith to protect confidential information of third parties delivered to it, provided that such Purchaser may deliver or disclose Confidential Information to (1) such Purchaser’s, directors, trustees, officers, employees, agents, attorneys and affiliates (to the extent such disclosure reasonably relates to the administration of the investment represented by such Purchaser’s Bonds), (2) such Purchaser’s financial advisors and other professional advisors who agree to hold confidential the Confidential Information substantially in accordance with the terms of this Section 14, (3) any other holder of any Bond, (4) any Institutional Investor to which such Purchaser sells or offers to sell such Bond

or any part thereof or any participation therein (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 14), (5) any federal or state regulatory authority having jurisdiction over such Purchaser, (6) the National Association of Insurance Commissioners or any similar organization, or any nationally recognized rating agency that requires access to information about such Purchaser’s investment portfolio or (7) any other Person to which such delivery or disclosure may be necessary (i) to effect compliance with any law, rule, regulation or order applicable to such Purchaser, (ii) in response to any subpoena or other legal process (provided that, subject to clause (iv) below, if not prohibited by applicable law, such Purchaser shall use commercially reasonable efforts to give notice to the Company thereof prior to such disclosure), (iii) in connection with any litigation to which such Purchaser is a party (provided that, subject to clause (iv) below, if not prohibited by applicable law, such Purchaser shall use commercially reasonable efforts to give notice to the Company thereof prior to such disclosure or (iv) if an Event of Default has occurred and is continuing, to the extent such Purchaser may reasonably determine such delivery and disclosure to be necessary or appropriate in the enforcement or for the protection of the rights and remedies under its Bonds, this Agreement or any other Bond Document. Each holder of a Bond, by its acceptance of a Bond, will be deemed to have agreed to be bound by and to be entitled to the benefits of this Section 14 as though it were a party to this Agreement. On reasonable request by the Company in connection with the delivery to any holder of a Bond of information required to be delivered to such holder under this Agreement or requested by such holder (other than a holder that is a party to this Agreement or its nominee), such holder will enter into an agreement with the Company embodying the provisions of this Section 14.

Section 15.1. Successors and Assigns. All covenants and other agreements contained in this Agreement by or on behalf of any of the parties hereto bind and inure to the benefit of their respective successors and assigns (including, without limitation, any subsequent holder of a Bond) whether so expressed or not.

Section 15.2. Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall (to the full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction.

Section 15.3. Construction. Each covenant contained herein shall be construed (absent express provision to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant. Where any provision herein refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person.

Section 15.4. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be an original but all of which together shall constitute one instrument. Each counterpart may consist of a number of copies hereof, each signed by less than all, but together signed by all, of the parties hereto.

Section 15.5. Governing Law. This Agreement shall be construed and enforced in accordance with, and the rights of the parties shall be governed by, the law of the State of New York excluding choice-of-law principles of the law of such State that would permit the application of the laws of a jurisdiction other than such State.

The execution hereof by the Purchasers shall constitute a contract among and us for the uses and purposes hereinabove set forth.

1. Order Granting Application issued by the Kansas Corporation Commission and dated March 24, 2008 in Docket No. 08-KG&E-829-SEC.

Under Section 114(a) of the Clean Air Act (Section 114), the EPA is conducting investigations nationwide to determine whether modifications at coal-fired power plants are subject to the New Source Review permitting program or New Source Performance Standards. These investigations focus on whether projects at coal-fired plants were routine maintenance or whether the projects were substantial modifications that could reasonably have been expected to result in a significant net increase in emissions. The New Source Review program requires companies to obtain permits and, if necessary, install control equipment to address emissions when making a major modification or a change in operation if either is expected to cause a significant net increase in emissions.

The EPA requested information from Westar Energy under Section 114 regarding projects and maintenance activities that have been conducted since 1980 at three coal-fired plants operated by the companies. On January 22, 2004, the EPA notified Westar Energy that certain projects completed at Jeffrey Energy Center violated certain permitting requirements of the New Source Review program.

Westar Energy has been in discussions with the EPA and the Department of Justice (DOJ) concerning this matter in an attempt to reach a settlement. The Company expects that any settlement could require Westar Energy and the Company to update or install emissions controls at Jeffrey Energy Center. Additionally, the companies might be required to update or install emissions controls at their other coal-fired plants, pay fines or penalties, or take other remedial action. If settlement discussions fail, the DOJ may consider whether to pursue an enforcement action against Westar Energy and the Company in Federal district court. The Company’s ultimate costs to resolve the NSR Investigation could be material. The Company believes that costs related to updating or installing emissions controls would qualify for recovery through the ECRR. If, however, a penalty is assessed against the Company, its share of the penalty could be material and may not be recovered in rates. The Company is not able to estimate the possible loss or range of loss at this time.

The closing opinion of Larry D. Irick, Esq., Vice President, General Counsel and Corporate Secretary of Westar Energy, which is called for by Section 4.4(a) of the Agreement, shall be dated the date of the Closing and addressed to the Purchasers and shall be to the effect that:

I am the General Counsel of Westar Energy and Secretary of the Company, and, in this regard, I have acted as counsel for the Company in connection with the issuance by the Company pursuant to the Agreement of $150,000,000 aggregate principal amount of Bonds. I am delivering this opinion pursuant to Section 4.4(a) of the Agreement.

I have (or an attorney in the Office of the Law Department of Westar Energy has) examined the originals, or copies certified or otherwise identified to our satisfaction, of such corporate records of the Company, certificates of public officials and of officers of the Company, and agreements, instruments and other documents, as I have deemed necessary as a basis for the opinions expressed below. As to questions of fact material to such opinions, I have, when relevant facts were not independently established by me, relied upon certificates of public officials or officers of the Company.

With your permission and without independent investigation, I have assumed the following: (i) the genuineness of all signatures (other than the signatures of the officers of the Company) on all documents examined by me; (ii) the authenticity of all documents submitted to me as originals and the conformity to authentic originals of all documents submitted to me as certified or photostatic copies; (iii) any certifications and documents dated prior to the date hereof remain true as of the date hereof; (iv) each certificate of a public official is accurate, complete and authentic and all official public records are accurate and complete and (v) the legal capacity of all natural persons.

Based upon the foregoing and upon such investigation as I have deemed necessary, I am of the opinion that:

(a) the Company has been duly incorporated, is validly existing as a corporation in good standing under the laws of the State of Kansas and is duly qualified to transact business and is in good standing in each jurisdiction in which the conduct of its business or its ownership or leasing of property requires such qualification (except where the failure to so qualify would not have a material adverse effect upon the business or financial condition of the Company, as a whole);

(b) the Amended Indenture has been duly authorized, executed and delivered by the Company;

(c) assuming the due authorization, execution and delivery by the other parties thereto, the Amended Indenture constitutes a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms (subject, as to enforcement of remedies, to applicable bankruptcy, reorganization, insolvency, fraudulent transfer, moratorium or other similar laws affecting creditors’ rights generally from time to time in effect and to general equity principles);

(d) the Amended Indenture has been duly recorded and filed in each place in which such recording or filing is required to protect and preserve the lien of the Amended Indenture, and all taxes and recording or filing fees required to be paid in connection with the execution, recording or filing of the Amended Indenture have been duly paid;

(e) the Company has good and sufficient title to, or a satisfactory easement in, all the real property, and has good and sufficient title to all the personal property described in the Amended Indenture as owned by it and subject to the lien of the Amended Indenture, except any which may have been released from the lien thereof pursuant to the provisions thereof, subject only to (1) minor leases and liens of judgments not prior to the lien of the Amended Indenture, which, in my opinion, do not interfere with the Company’s business, (2) minor defects, irregularities and deficiencies in titles of properties and rights-of-way which, in my opinion, do not materially impair the use of such property and rights-of-way for the purposes for which they are held by the Company and (3) other excepted encumbrances as defined in the Amended Indenture; subject to the qualifications set forth in this opinion, the Amended Indenture constitutes a valid, direct first mortgage lien upon said properties and upon all franchises owned by the Company, which properties and franchises include all the physical properties and franchises of the Company (other than classes of property expressly excepted in the Amended Indenture); all physical properties and franchises (other than classes of property expressly excepted in the Amended Indenture as aforesaid) thereafter acquired by the Company will, upon such acquisition, become subject to the lien thereof, subject, however, to liens permitted thereby and to any liens existing or placed upon such properties at the time of the acquisition thereof by the Company; and the descriptions of all such properties and assets contained in the granting clauses of the Amended Indenture are correct and adequate for the purposes of the Amended Indenture;

(f) the Bonds have been duly authorized, executed, and delivered by the Company;

(g) when the Bonds have been duly executed and authenticated in accordance with the provisions of the Amended Indenture, the Bonds will be valid and binding obligations of the Company, enforceable against it in accordance with their terms (subject, as to enforcement or remedies, to applicable bankruptcy, reorganization, insolvency, fraudulent transfer, moratorium or other similar laws affecting creditors’ rights generally from time to time in effect and to general equity principles), and will be entitled to the benefits of the Amended Indenture and to the lien of the Amended Indenture;

(h) the Agreement has been duly authorized, executed and delivered by the Company, and, assuming the due authorization, execution and delivery by the other party thereto, constitutes a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms (subject, as to enforcement of remedies, to applicable bankruptcy, reorganization, insolvency, fraudulent transfer, moratorium or other similar laws affecting creditors’ rights generally from time to time in effect and to general equity principles);

(i) the execution and delivery by the Company of, and the performance by the Company of its obligations under, the Agreement, the Amended Indenture and the Bonds, will not contravene (x) any provision of law of the United States (including laws relating specifically to electric utility companies and the electric utility industry), Kansas, or, to the best of my knowledge, of any other state or jurisdiction of the United States that in my experience is normally applicable to general business corporations of the same type as the Company in relation to transactions of the type contemplated by the Agreement, the Amended Indenture and the Bonds, (y) the articles of incorporation or by-laws of the Company or (z) to the best of my knowledge, any material agreement or other material instrument binding upon the Company;

(j) the Company possesses valid franchises, certificates of convenience and authority, licenses and permits authorizing it to carry on the electric utility business in which it is engaged, except in the cases that the failure to possess such franchises, certificates, licenses or permits, individually or in the aggregate, would not be reasonably expected to have a material adverse effect on the Company, taken as a whole, and the Company has not received any notice of proceedings relating to the revocation or modification of any such franchise, certificate of convenience and authority, license or permit which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would reasonably be expected to have a material adverse effect;

(k) there is no pending, or to my knowledge, threatened action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Company or its property that is not disclosed in Westar Energy’s Annual Report in Form 10-K for the year ended December 31, 2007, except in each case for proceedings that, if the subject of an unfavorable decision, ruling or finding could not reasonably be expected to have a material adverse effect upon the business or financial condition of the Company, as a whole; and

(l) The State Corporation Commission of the State of Kansas (“KCC”) has authorized the issuance of the Bonds pursuant to an order dated March 24, 2008. No additional consent, approval, authorization, filing with or order of (a) the Federal Energy Regulatory Commission (“FERC”) under the Federal Power Act, (b) the KCC or (c) to my knowledge, any court or governmental agency or body is required in connection with the transactions contemplated herein.

This opinion is limited to the matters specifically stated in this letter, and no further opinion is to be implied or may be inferred beyond the opinions specifically stated herein. My opinions are limited to the laws of the State of Kansas (except state securities or blue sky laws), the Federal Power Act and laws, rules or regulations promulgated by or within the enforcement authority of FERC, and I do not express any opinion herein concerning any other law. This opinion is based solely on the state of the law as of the date of this opinion. I specifically disclaim any obligation to monitor any of the matters stated in this opinion or to advise the persons entitled to rely on this opinion of any change in law or fact after the date of this opinion that might affect any of the opinions stated herein. This opinion is rendered solely for the benefit of, and may be relied on by you and may not be released to or relied upon by any other person or for any other purpose, except that your successors and each future holder of the any Bond under (and permitted by) the Agreement may rely on this opinion as of the original date of this opinion

subject to the limitations, qualifications, exceptions and assumptions set forth herein and this opinion may be provided to, but not relied upon by, governmental authorities (including the National Association of Insurance Commissioners).

For purposes of opinion (a) below, we have assumed that the Agreement has been duly authorized, executed and delivered by the Company.

(a) The Company is not, and after giving effect to the offering and sale of the Bonds and the application of the proceeds thereof as described in the Agreement will not be, required to register as an “investment company” as such term is defined in the Investment Company Act of 1940, as amended;

(b) The Agreement constitutes the legal, valid and binding agreement of the Company enforceable against the Company in accordance with its terms except that the enforcement thereof may be subject to (1) bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or other similar laws now or hereafter in effect relating to or affecting creditors’ rights or remedies generally, (2) concepts of reasonableness and equitable principles of general applicability and (3) the remedy of specific performance and injunctive and other forms of equitable relief may be subject to equitable defenses and to the discretion of the court before which any proceedings therefor may be brought (regardless of whether enforcement is sought in a proceeding at law or in equity);

(d) No consent, approval, authorization, or order of, or qualification with, any state or federal governmental body or agency under the laws of the State of New York or any federal law of the United States of America (except with respect to consents, approvals and authorizations relating specifically to public utility companies or the utilities industry, as to which we are not called upon to express any opinion) that in our experience is normally applicable to general business corporations of the same type as the Company in relation to transactions of the type contemplated by the Documents is required for the execution, delivery and performance by the Company of its obligations under the Documents, except such as may be required under federal or state securities or Blue Sky laws as to which we express no opinion except as set forth in paragraph (e) below; and

(e) Based upon the representations, warranties and agreements of the Company and you in the Agreement, it is not necessary in connection with the offer, sale and delivery of the Bonds to you under the Agreement to register the Bonds under the Securities Act of 1933, as amended, or to qualify the Amended Indenture under the Trust Indenture Act of 1939, as amended, it being understood that no opinion is expressed as to any subsequent offer or resale of any Bonds.

We are members of the Bars of the States of New York and California and the foregoing opinion is limited to the laws of the State of New York and the federal laws of the United States of America (except with respect to such laws relating specifically to public utility companies or the utilities industry).

This opinion is rendered solely to you in connection with the above matter.

1. The Company is a corporation validly existing and in good standing under the laws of the State of Kansas.

2. The issuance, sale and delivery of the Bonds being delivered on the date of the Closing under the circumstances contemplated by this Agreement and the Supplemental Indenture do not, under existing law, require the registration of such Bonds under the Securities Act of 1933, as amended, or the qualification of the Amended Indenture under the Trust Indenture Act of 1939, as amended.

The opinion of Schiff Hardin LLP shall also state that the opinions of Larry D. Irick, Esq. and Davis Polk & Wardwell are satisfactory in scope and form to Schiff Hardin LLP and that, in their opinion, the Purchasers are justified in relying thereon.

In rendering the opinion set forth in paragraph 1 above, Schiff Hardin LLP may rely, as to matters referred to in paragraph 1, solely upon an examination of the Certificate of Incorporation certified by, and a certificate of good standing of the Company from, the Secretary of State of the State of Kansas. The opinion of Schiff Hardin LLP is limited to the laws of the State of New York and the Federal laws of the United States.

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

SECTION 1. There shall be a series of bonds designated “6.15% Series A due May 15, 2023” (herein sometimes referred to as the “Fifty-sixth Series”), each of which shall also bear the descriptive title, First Mortgage Bond, and the form thereof, which is established by Resolution

Bonds of the Fifty-sixth Series shall be limited to $50,000,000 in aggregate principal amount, except as provided in Section 16 of the Mortgage, shall mature on May 15, 2023, and shall be issued as fully registered bonds in denominations of One Million Dollars (or such lesser amount as would permit any holder thereof to transfer its entire holding of Bonds of the Fifty-sixth Series) and in any multiple or multiples of One Thousand Dollars in excess thereof. Bonds of the Fifty-sixth Series shall bear interest from the date of their issuance at the rate of 6.15% per annum, payable semi-annually on May 15 and November 15 of each year, beginning November 15, 2008, to holders of record on the preceding May 1 or November 1, as applicable. The principal of, Make-Whole Amount, if any, and interest on Bonds of the Fifty-sixth 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, except as follows. So long as any Purchaser (as defined in that certain Bond Purchase Agreement dated as of May 15, 2008 (the “Bond Purchase Agreement”)) or its nominee shall be the holder of any Bond, the Company will (or will cause its agent to) pay all sums becoming due with respect to such Bond (including, without limitation, for principal, Make-Whole Amount, if any, and interest) by the method and at the address specified for such purpose for such Purchaser in Schedule A to the Bond Purchase Agreement, or by such other method or at such other address as such Purchaser shall have from time to time specified to the Company in writing for such purpose, without the presentation or surrender of such Bond or the making of any notation thereon, except that upon written request of the Company made concurrently with or reasonably promptly after payment or redemption in full of any Bond, such Purchaser shall surrender such Bond for cancellation, reasonably promptly after any such request, to the Company at its principal executive office or to the Corporate Trustee at its principal corporate trust office. Prior to any sale or other disposition of any Bond held by any Purchaser or its nominee such person will, at its election, either endorse thereon the amount of principal paid thereon and the last date to which interest has been paid thereon or surrender such Bond to the Company or the Corporate Trustee in exchange for a new Bond or Bonds pursuant to the terms of this Fifty-first Supplemental Indenture. The Company will afford the benefits of this Section to any Institutional Investor (as defined in the Bond Purchase Agreement) that is the direct or indirect transferee of any Bond purchased by any Purchaser under this Fifty-first Supplemental Indenture and the Bond Purchase Agreement and has made the same agreement relating to such Bond as such Purchaser has made in Section 8.2 of the Bond Purchase Agreement.

SECTION 2. Bonds of the Fifty-sixth Series shall be dated as in Section 10 of the Mortgage provided.

SECTION 3. The Bonds of the Fifty-sixth Series, upon the mailing of notice and in the manner provided in Article X of the Mortgage (except that no published notice shall be required for the Bonds of the Fifty-sixth Series) and with the effect provided in Section 54 thereof, shall be redeemable at the option of the Company, as a whole at any time or in part from time to time, at a redemption price equal to 100% of the principal amount of the Bonds of the Fifty-sixth Series to be redeemed plus accrued and unpaid interest of the principal amount being redeemed to the date of redemption plus the Make-Whole Amount applicable thereto. Notwithstanding Section 52 of the Mortgage, in the event a partial redemption of Bonds of the Fifty-sixth Series, Bonds of the Fifty-sixth Series will be redeemed on a pro rata basis.

“Make-Whole Amount” means, with respect to any Bond of the Fifty-sixth Series, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Bond of the Fifty-sixth Series over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole Amount, the following terms have the following meanings:

“Called Principal” means, with respect to any Bond of the Fifty-sixth Series, the principal of such Bond of the Fifty-sixth Series that is to be redeemed.

“Discounted Value” means, with respect to the Called Principal of any Bond of the Fifty-sixth Series, the amount obtained by discounting to present value all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the bond of such Series is payable) equal to the Reinvestment Yield with respect to such Called Principal.

“Reinvestment Yield” means, with respect to the Called Principal of any Bond of the Fifty-sixth Series, .50% over the yield to maturity implied by (i) the yields reported as of 10:00 a.m. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets (“Bloomberg”) or, if Page PX1 (or its successor screen on Bloomberg) is unavailable, the Telerate Access Service screen which corresponds most closely to Page PX1 for the most recently issued actively traded U.S. Treasury securities having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable (including by way of interpolation), the Treasury Constant Maturity Series Yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (519) (or any comparable successor publication) for actively traded U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. Such implied yield will be determined, if necessary, by (a) converting U.S. Treasury bill quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between (1) the actively traded U.S. Treasury security with the maturity closest to and greater than such Remaining Average Life and (2) the actively traded U.S. Treasury security with the maturity closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable bond of such Series.

“Remaining Average Life” means, with respect to any Called Principal, the number of years (calculated to the nearest one-twelfth year) obtained by dividing (i) the sum of the products obtained by multiplying (a) that portion of each Remaining Scheduled Payment that constitutes a scheduled principal payment with respect to such Called Principal by (b) the number of years (calculated to the nearest one-twelfth year) that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment, by (ii) such Called Principal.

“Remaining Scheduled Payments” means, with respect to the Called Principal of any Bond of the Fifty-sixth Series, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms of the Bonds of the Fifty-sixth Series, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to the terms of this Supplemental Indenture.

“Settlement Date” means, with respect to the Called Principal of any Bond of the Fifty-sixth Series, the date on which such Called Principal is to be redeemed.

SECTION 4. Bonds of the Fifty-sixth Series shall initially be offered and sold in reliance on the exemption contained under Section 4(2) of the Securities Act of 1933 (the “Securities Act”) to an institution which is an “accredited investor” as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act.

The Substituted Mortgage Bonds may only be delivered to the Corporate Trustee (A) upon execution and delivery of a mortgage and deed of trust or similar instrument which, among other things, contains requirements (i) for the delivery of net earnings certificates, on terms and conditions and in circumstances consistent with the requirements of the Mortgage (except that the ratio of two and one-half (2¹/2) times contained in Section 27 of the Mortgage may be replaced with a ratio of two (2) times), (ii) that the principal amount of bonds authenticated on the basis of property additions not exceed 70% of the lesser of cost or fair market value thereof, (iii) that property and cash be released from the lien of such instrument upon terms and conditions consistent with the

requirements of the Mortgage, (iv) that the Company provide for maintenance and repair expenditures in a manner substantially consistent with Section 38 of the Mortgage and (v) that bonds may be accelerated by the holders of 25% of the aggregate principal amount of all bonds outstanding under such instrument, and (B) upon receipt by the Corporate Trustee of (i) ratings, at the Company’s expense, of the original bonds from both Moody’s and S&P (as hereinafter defined), to the extent the original bonds were not so rated, such ratings not giving effect to any downgrade following the announcement of any transaction related to or involving the issuance of Substituted Mortgage Bonds, (ii) a letter from Moody’s, dated within ten days prior to the date of delivery of the Substituted Mortgage Bonds, stating that its rating of the Substituted Mortgage Bonds is at least equal to the rating on the original bonds (not giving effect to any downgrade of the original bonds following the announcement of any transaction related to or involving the issuance of Substituted Mortgage Bonds), (iii) a letter from S&P, dated within ten days prior to the date of delivery of the Substituted Mortgage Bonds, stating that its rating of the Substituted Mortgage Bonds is at least equal to its rating on the original bonds (not giving effect to any downgrade of the original bonds following the announcement of any transaction related to or involving the issuance of Substituted Mortgage Bonds), (iv) an opinion of counsel which may be counsel to the Company or any successor entity, to the effect that the Substituted Mortgage Bonds shall have been duly and validly authorized, executed, authenticated, and delivered and shall constitute the valid, legally binding and enforceable obligations of the Company or any other successor entity enforceable in accordance with their terms, except as limited by bankruptcy, insolvency or other laws affecting the enforcement of mortgagees’ and other creditors’ right and shall be entitled to the benefit of the mortgage and deed of trust or other similar instrument pursuant to which they shall have been issued, and (v) such other certificates and documents with respect to the issuance and delivery of the Substituted Mortgage Bonds as may be required by law or as the Corporate Trustee may reasonably request. The Company may make such other amendments to the Mortgage as may be necessary or desirable in the opinion of the Company to effect the foregoing.

Bonds of the Fifty-seventh Series shall bear interest from the date of their issuance at the rate of 6.64% per annum, payable semi-annually on May 15 and November 15 of each year, beginning November 15, 2008, to holders of record on the preceding May 1 or November 1, as applicable.

Prior to any sale or other disposition of any Bond held by any Purchaser or its nominee such person will, at its election, either endorse thereon the amount of principal paid thereon and the last date to which interest has been paid thereon or surrender such Bond to the Company or the Corporate Trustee in exchange for a new Bond or Bonds pursuant to the terms of this Fifty-first Supplemental Indenture. The Company will afford the benefits of this Section to any Institutional Investor (as defined in the Bond Purchase Agreement) that is the direct or indirect transferee of any Bond purchased by any Purchaser under this Fifty-first Supplemental Indenture and the Bond Purchase Agreement and has made the same agreement relating to such Bond as such Purchaser has made in Section 8.2 of the Bond Purchase Agreement.
