It is the intention of the parties hereto that (other than for United States federal income tax purposes and, to the extent consistent with applicable state tax laws, state income and franchise tax purposes) the sale, transfer, assignment, setting over and conveyance herein contemplated constitutes a sale or other absolute transfer of all right, title and interest of the Seller in and to the Securitized Utility Tariff Property from the Seller to the Issuer.

(c)    Transfer Filings.

(i)    The Seller is the sole owner of all the rights and interests under the Financing Order to be sold to the Issuer on the Closing Date.

6

Section 3.10    The Financing Order.

(a)    The Financing Order was issued by the Kansas Commission on August 18, 2022 in accordance with the Securitization Act; the Financing Order and the process by which it was issued comply with all applicable laws, rules and regulations of the State of Kansas and the federal laws of the United States, and the Financing Order is final, non-appealable and in full force and effect.

(b)    As of the date of issuance of the Securitized Utility Tariff Bonds, the Securitized Utility Tariff Bonds will be entitled to the protections provided by the Securitization Act and the Financing Order, the Issuance Advice Letter and the Securitized Utility Tariff Charges authorized therein will have become irrevocable and not subject to reduction, impairment or adjustment by further action of the Kansas Commission, except for changes made pursuant to the adjustment mechanism authorized under the Securitization Act, and the Issuance Advice Letter and the Securitized Utility Tariff have been filed in accordance with the Financing Order. The Issuance Advice Letter have been filed in accordance with the Financing Order. The initial Securitized Utility Tariff Charges and the final terms of the Securitized Utility Tariff Bonds set forth in the Issuance Advice Letter have become effective. No other approval, authorization, consent, order or other action of, or filing with any Governmental Authority is required in connection with the creation of the Securitized Utility Tariff Property transferred on such date, except those that have been obtained or made.

Section 3.11    State Action.

(a)    Under K.S.A. §66-1,252(a), the State of Kansas has pledged that it will not take any action listed in such section or, except for changes made pursuant to the adjustment mechanism authorized under the Securitization Act, reduce, alter or impair the Securitized Utility Tariff Charges until the principal, interest and premium, if any, and any other charges incurred and contracts to be performed in connection with the Securitized Utility Tariff Bonds, have been paid and performed in full.

(b)    Under the laws of the State of Kansas and the federal laws of the United States, a reviewing court of competent jurisdiction would hold that (x) the State of Kansas could not constitutionally take any action of a legislative character, including the repeal or amendment of the Securitization Act, which would substantially limit, alter or impair the Securitized Utility Tariff Property or other rights vested in the Securitized Utility Tariff Bondholders pursuant to the Financing Order, or substantially limit, alter, impair or reduce the value or amount of the Securitized Utility Tariff Property, unless such action is a reasonable and necessary exercise of the State of Kansas’s sovereign powers based on reasonable conditions and of a character reasonable and appropriate to the emergency or other significant and legitimate public purpose justifying such action, and, (y) under the takings clauses of the State of Kansas and United States Constitutions, if the court concludes that the Securitized Utility Tariff Property is protected by the takings clauses, the State of Kansas could not repeal or amend the Securitization Act or take any other action in contravention of its pledge referred to in subsection (a) above without paying just compensation to the Securitized Utility Tariff Bondholders, as determined by a court of

7

competent jurisdiction, if doing so would constitute a permanent appropriation of a substantial property interest of the Securitized Utility Tariff Bondholders in the Securitized Utility Tariff Property and deprive the Securitized Utility Tariff Bondholders of their reasonable expectations arising from their investments in the Securitized Utility Tariff Bonds; however, there is no assurance that, even if a court were to award just compensation, it would be sufficient to pay the full amount of principal of and interest on the Securitized Utility Tariff Bonds.

(c)    Under the laws of the United States Constitution, a Kansas state court reviewing an appeal of Kansas Commission action of a legislative character would conclude that the Kansas Commission Pledge (i) creates a binding contractual obligation of the State of Kansas for purposes of the contract clauses of the United States Constitution, and (ii) the Kansas Commission could not take any action of a legislative character, including the rescission or amendment of the Financing Order, which violates the Kansas Commission Pledge in a manner that substantially reduces, limits or impairs the value of the Securitized Utility Tariff Property or the Securitized Utility Tariff Charges, prior to the time that the Securitized Utility Tariff Bonds are paid in full and discharged, unless the Kansas Commission action clearly is exercised for a public end and is reasonably necessary to the accomplishment of that public end so as not to be arbitrary, capricious or an abuse of authority. There is no assurance, however, that, even if a court were to award just compensation it would be sufficient to pay the full amount of principal and interest on the Securitized Utility Tariff Bonds.

Section 3.12    No Court Order. There is no order by any court providing for the revocation, alteration, limitation or other impairment of the Securitization Act, the Financing Order, the Issuance Advice Letter, the Securitized Utility Tariff Property or the Securitized Utility Tariff Charges or any rights arising under any of them or that seeks to enjoin the performance of any obligations under the Financing Order.

Section 3.13    Approvals Concerning the Securitized Utility Tariff Property. Under the laws of the State of Kansas and the federal laws of the United States, no other approval, authorization, consent, order or other action of, or filing with any Governmental Authority is required in connection with the creation or transfer of the Seller’s rights and interests under the Financing Order and the Issuer’s purchase of the Securitized Utility Tariff Property from the Seller, except those that have been obtained or made.

Section 3.14    No Right of Kansas Voters to Act by Initiative or Referendum. Apart from amending the Constitution of the State of Kansas, the citizens of the State of Kansas currently do not have the constitutional right to adopt or revise state laws by initiative or referendum.

Section 3.15    Tax Liens. The Seller is not aware of any judgment or tax Lien filings against the Issuer or the Seller that would result in a Lien on the Securitized Utility Tariff Property.

Section 3.16    Assumptions. Based on information available to the Seller on the date hereof, the assumptions used in calculating the Securitized Utility Tariff Charges in the Issuance Advice Letter are reasonable and made in good faith; however, notwithstanding the foregoing,

8

THE SELLER MAKES NO REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, THAT BILLED SECURITIZED UTILITY TARIFF CHARGES WILL BE ACTUALLY COLLECTED FROM CUSTOMERS, OR THAT AMOUNTS ACTUALLY COLLECTED ARISING FROM THE SECURITIZED UTILITY TARIFF CHARGES WILL IN FACT BE SUFFICIENT TO MEET THE PAYMENT OBLIGATIONS ON THE SECURITIZED UTILITY TARIFF BONDS OR THAT THE ASSUMPTIONS USED IN CALCULATING SUCH SECURITIZED UTILITY TARIFF CHARGES WILL IN FACT BE REALIZED.

Section 3.17    Creation of the Securitized Utility Tariff Property.

(a)    Upon the effectiveness of the Financing Order, the transfer of the Seller’s rights and interests under the Financing Order related to the Securitized Utility Tariff Bonds and the Issuer’s purchase of the Securitized Utility Tariff Property from the Seller pursuant to this Agreement, the Securitized Utility Tariff Property will constitute a present contract right vested in the Issuer.

(b)    Upon the effectiveness of the Financing Order, the Issuance Advice Letter and the Securitized Utility Tariff, the transfer of the Seller’s rights and interests under the Financing Order and the Issuer’s purchase of the Securitized Utility Tariff Property from the Seller pursuant to this Agreement, the Securitized Utility Tariff Property includes:

(c)    Upon the effectiveness of the Issuance Advice Letter and the Securitized Utility Tariff, the transfer of the Seller’s rights and interests under the Financing Order and the Issuer’s purchase of the Securitized Utility Tariff Property from the Seller on the Closing Date pursuant to this Agreement, the Securitized Utility Tariff Property will not be subject to any Lien created by a previous indenture.

Section 3.18    Prospectus. As of the date hereof, the information describing the Seller under the captions “Review of Securitized Utility Tariff Property” and “The Depositor, Seller, Initial Servicer and Sponsor” in the Prospectus is true and correct in all material respects.

Section 3.19    Nature of Representations and Warranties. The representations and warranties set forth in Section 3.08 and Section 3.10 through Section 3.18, insofar as they involve conclusions of law, are made not on the basis that the Seller purports to be a legal expert or to be rendering legal advice, but rather to reflect the parties’ good faith understanding of the legal basis on which the parties are entering into this Agreement and the other Basic Documents and the basis on which the Securitized Utility Tariff Bondholders are purchasing the Securitized Utility Tariff Bonds, and to reflect the parties’ agreement that, if such understanding turns out to be incorrect or inaccurate, the Seller will be obligated to indemnify the Issuer and its permitted assigns (to the extent required by and in accordance with Section 5.01), and that the Issuer and its permitted assigns will be entitled to enforce any rights and remedies under the Basic Documents on account of such inaccuracy to the same extent as if the Seller had breached any other representations or warranties hereunder.

(a)    to protect the Issuer and the Securitized Utility Tariff Bondholders from claims, state actions or other actions or proceedings of third parties which, if successfully pursued, would result in a breach of any representation set forth in Article III; or

(b)    so long as the Seller is also the Servicer, to block or overturn any attempts to cause a repeal of, modification of or supplement to the Securitization Act, the Financing Order, the Issuance Advice Letter or the rights of Securitized Utility Tariff Bondholders by legislative enactment (including any action of the Kansas Commission of a legislative character) or constitutional amendment that would be materially adverse to the Issuer, the Trustee or the Securitized Utility Tariff Bondholders.

13

or property before any penalty accrues thereon if the failure to pay any such taxes, assessments and governmental charges would, after any applicable grace periods, notices or other similar requirements, result in a Lien on the Securitized Utility Tariff Property; provided that no such tax need be paid if the Seller or any of its Affiliates is contesting the same in good faith by appropriate proceedings promptly instituted and diligently conducted and if the Seller or such Affiliate has established appropriate reserves as shall be required in conformity with generally accepted accounting principles.

Section 4.10    Filings Pursuant to Financing Order. The Seller shall comply with all filing requirements imposed upon the Seller in its capacity as such by the Financing Order, including making any such post-closing filings.

Section 4.11    Issuance Advice Letter. The Seller hereby agrees not to withdraw the filing of the Issuance Advice Letter with the Kansas Commission.

Section 4.12    Securitized Utility Tariff. The Seller hereby agrees to make all reasonable efforts to keep the Securitized Utility Tariff in full force and effect at all times.

Promptly after obtaining knowledge thereof, in the event of a breach in any material respect (without regard to any materiality qualifier contained in such representation, warranty or covenant) of any of the Seller’s representations, warranties or covenants contained herein, the Seller shall promptly notify the Issuer, the Trustee and the Rating Agencies of such breach. For the avoidance of doubt, any breach which would adversely affect scheduled payments on the Securitized Utility Tariff Bonds will be deemed to be a material breach for purposes of this Section 4.13.

Section 4.14    Further Assurances. Upon the reasonable request of the Issuer, the Seller shall execute and deliver such further instruments and do such further acts as may be reasonably necessary to carry out more effectually the provisions and purposes of this Agreement.
