ARTICLE TWO

Form of Guarantee

          Guarantees to be endorsed on the Securities of Series No. ___shall be in substantially the form set forth below:

[FORM OF GUARANTEE]

     PPL Corporation, a corporation organized under the laws of the Commonwealth of Pennsylvania (the “Guarantor”, which term includes any successor under the Indenture (the “Indenture”) referred to in the Security upon which this Guarantee is endorsed), for value received, hereby fully and unconditionally guarantees to the Holder of the Security upon which this Guarantee is endorsed, the due and punctual payment of the principal of, and premium, if any, and interest, if any, on such Security when and as the same shall become due and payable, whether at the Stated Maturity, by declaration of acceleration, call for redemption, or otherwise, in accordance with the terms of such Security and of the Indenture. In case of the failure of PPL Capital Funding, Inc., a corporation organized under the laws of the State of Delaware (the “Company”, which term includes any successor under the Indenture), punctually to make any such payment, the Guarantor hereby agrees to cause such payment to be made punctually when and as the same shall become due and payable, whether at the Stated Maturity or by declaration of acceleration, call for redemption or otherwise, and as if such payment were made by the Company.

     The Guarantor hereby agrees that its obligations hereunder shall be absolute and unconditional irrespective of, and shall be unaffected by, any invalidity, irregularity or unenforceability of such Security or the Indenture, any failure to enforce the provisions of such Security or the Indenture, or any waiver, modification or indulgence granted to the Company with respect thereto, by the Holder of such Security or the Trustee or any other circumstance which may otherwise constitute a legal or equitable discharge or defense of a surety or guarantor; provided, however, that notwithstanding the foregoing, no such waiver, modification or indulgence shall, without the consent of the Guarantor, increase the principal amount of such Security, or increase the interest rate thereon, or change any redemption provisions thereof (including any change to increase any premium payable upon redemption thereof) or change the Stated Maturity thereof.

     The Guarantor hereby waives the benefits of diligence, presentment, demand for payment, any requirement that the Trustee or the Holder of such Security exhaust any right or take any action against the Company or any other Person, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest or notice with respect to such Security or the indebtedness evidenced thereby and all demands whatsoever, and covenants that this Guarantee will not be discharged in respect of such Security except by complete

performance of the obligations contained in such Security and in this Guarantee. This Guarantee shall constitute a guaranty of payment and not of collection. The Guarantor hereby agrees that, in the event of a default in payment of principal, or premium, if any, or interest, if any, on such Security, whether at its Stated Maturity, by declaration of acceleration, call for redemption, or otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by, the Holder of such Security, subject to the terms and conditions set forth in the Indenture, directly against the Guarantor to enforce this Guarantee without first proceeding against the Company.

     The obligations of the Guarantor hereunder with respect to such Security shall be continuing and irrevocable until the date upon which the entire principal of, premium, if any, and interest, if any, on such Security has been, or has been deemed pursuant to the provisions of Article Seven of the Indenture to have been, paid in full or otherwise discharged.

     The obligations evidenced by this Guarantee are, to the extent provided in the Indenture, subordinated and subject in right of payment to the prior payment in full of all Senior Indebtedness (as defined in the Indenture) of the Guarantor, and this Guarantee is issued subject to the provisions of the Indenture with respect thereto. Each Holder of a Security upon which this Guarantee is endorsed, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to acknowledge or effectuate the subordination so provided and (c) appoints the Trustee his attorney-in fact for any and all such purposes. Each Holder hereof, by his acceptance hereof, hereby waives all notice of the acceptance of the subordination provisions contained herein and in the Indenture by each holder of Senior Indebtedness, whether now outstanding or hereafter incurred, and waives reliance by each such Holder upon said provisions.

     The Guarantor shall be subrogated to all rights of the Holder of such Security upon which this Guarantee is endorsed against the Company in respect of any amounts paid by the Guarantor on account of such Security pursuant to the provisions of this Guarantee or the Indenture; provided, however, that the Guarantor shall not be entitled to enforce or to receive any payments arising out of, or based upon, such right of subrogation until the principal of, and premium, if any, and interest, if any, on all Securities issued under the Indenture shall have been paid in full.

     This Guarantee shall remain in full force and effect and continue notwithstanding any petition filed by or against the Company for liquidation or reorganization, the Company becoming insolvent or making an assignment for the benefit of creditors or a receiver or trustee being appointed for all or any significant part of the Company’s assets, and shall, to the fullest extent permitted by law, continue to be effective or reinstated, as the case may be, if at any time payment of the Security upon which this Guarantee is endorsed, is, pursuant to

applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by the Holder of such Security, whether as a “voidable preference,” “fraudulent transfer,” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned on such Security, such Security shall, to the fullest extent permitted by law, be reinstated and deemed paid only by such amount paid and not so rescinded, reduced, restored or returned.

     This Guarantee shall not be valid or obligatory for any purpose until the certificate of authentication of the Security upon which this Guarantee is endorsed shall have been manually executed by or on behalf of the Trustee under the Indenture.

     All terms used in this Guarantee which are defined in the Indenture shall have the meanings assigned to them in such Indenture.

     This Guarantee shall be deemed to be a contract made under the laws of the State of New York, and for all purposes shall be governed by and construed in accordance with the laws of the State of New York.

     IN WITNESS WHEREOF, the Guarantor has caused this Guarantee to be executed as of the date first written above.
