WHEREAS, the Company proposes to establish and issue further series of Securities pursuant to the terms of the Base Indenture and desires to modify paragraph four of Section 11.02 of the Base Indenture with respect to all series of notes now or in the future established and issued; and

WHEREAS, the entry into this Third Supplemental Indenture by the parties hereto is in all respect authorized by the provisions of the Base Indenture; and

WHEREAS, all conditions necessary to authorize the execution and delivery of this Third Supplemental Indenture and to make it a valid and binding obligation of the Company have been done or performed;

NOW, THEREFORE:

In consideration of the promises and the purchases of the Future Senior Notes by the Holders thereof, the Company and the Trustee mutually covenant and agree for the equal and proportionate benefit of the respective Holders from time to time of the Future Senior Notes as follows:

Section 1. The Base Indenture is hereby amended with respect to all series of notes now established and issued and with respect to any and all Future Senior Notes by amending paragraph four of Section 11.02 of the Base Indenture to provide as follows:

“No later than 10:00 a.m. on the redemption date specified in the notice of redemption given as provided in this Section, the Company will deposit with the Trustee or with one or more paying agents (or, if the Company is acting as its own paying agent, set aside, segregate and hold in trust) an amount of money sufficient to redeem on the redemption date all the Securities of a series so called for redemption at the appropriate redemption price, together with accrued interest to the date fixed for redemption. The Company will deliver to the Trustee at least 5 days prior to the date of notice of redemption an Officer’s Certificate stating the aggregate Principal Amount of Securities of such series to be redeemed.”

Section 2. The recitals and statements in this Third Supplemental Indenture are made by the Company only and not by the Trustee, and the Trustee makes no representation as to the validity or sufficiency of this Third Supplemental Indenture (other than with respect to the due authorization, execution and delivery of this Third Supplemental Indenture by the Trustee). All of the provisions contained in the Base Indenture in respect of the rights, privileges, immunities, powers and duties of the Trustee shall be applicable in respect of the Future Senior Notes and of this Third Supplemental Indenture as fully and with like effect as if set forth herein in full.

Section 5. In the event of a conflict between the terms and conditions of the Base Indenture and the terms and conditions of this Third Supplemental Indenture, then the terms and conditions of this Third Supplemental Indenture shall prevail; provided that if and to the extent that any provision of this Third Supplemental Indenture limits, qualifies or conflicts with another provision which is required to be included herein or in the Base Indenture by the Trust Indenture Act of 1939, as amended, such required provision shall control.

Section 6. All covenants and agreements in this Third Supplemental Indenture by the Company shall bind its successors and assigns, whether so expressed or not.

Section 7. In case any provision in this Third Supplemental Indenture shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired hereby.

Section 8. Nothing in this Third Supplemental Indenture, expressed or implied, shall give to any Person, other than the parties hereto and any Paying Agent and any Registrar for, and any Person authorized to authenticate and deliver on behalf of the Trustee, the Future Senior Notes and their successors under the Indenture, and the Holders of the Future Senior Notes any benefit or any legal or equitable right, remedy or claim under this Third Supplemental Indenture.
