“(a) In case the Company shall desire to exercise such right to redeem all or, as the case may be, a portion of the Notes in accordance with any right the Company reserved for itself to do so pursuant to Section 2.01 hereof, the Company shall, or shall cause the Trustee to, give notice of such redemption to holders of the Notes to be redeemed by mailing, first class postage prepaid, a notice of such redemption not less than 30 days and not more than 60 days before the date fixed for redemption of that series to such holders at their last addresses as they shall appear upon the Security Register, unless a shorter period is specified in the Notes to be redeemed. Any notice that is mailed in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the registered holder receives the notice. In any case, failure duly to give such notice to the holder of the Notes designated for redemption in whole or in part, or any defect in the notice, shall not affect the validity of the proceedings for the redemption of any other Notes or any other series. In the case of any redemption of Notes prior to the expiration of any restriction on such redemption provided in the terms thereof or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officer’s Certificate evidencing compliance with any such restriction.

Each such notice of redemption shall specify the date fixed for redemption and the redemption price at which the Notes are to be redeemed, and shall state that payment of the redemption price of the Notes to be redeemed will be made at the office or agency of the Company, upon presentation and surrender of such Notes, that interest accrued to the date fixed for redemption will be paid as specified in said notice, that from and after said date interest will cease to accrue and that the redemption is from a sinking fund, if such is the case.

(b) reduce the percentage in principal amount of the Outstanding Notes, the consent of whose Holders is required for any such supplemental indenture, or the consent of whose Holders is required for any waiver with respect to such series (of compliance with certain provisions of this Indenture or certain defaults hereunder and their consequences) provided for in this Indenture, or reduce any requirements of Section 8.01 for quorum or voting, or

If a record date is fixed, the Holders on such record date, or their duly designated proxies, and only such Persons, shall be entitled to consent to such supplemental indenture, whether or not such Holders remain Holders after such record date; provided, that unless such consent shall have become effective by virtue of the requisite percentage having been obtained prior to the date that is 90 days after such record date, any such consent previously given shall automatically and without further action by any Holder be cancelled and of no further effect.”

“ARTICLE 14

The Company may at its option by Board Resolution, at any time, with respect to the Notes, elect to have either Section 14.02 (if applicable) or Section 14.03 (if applicable) be applied to such Outstanding Notes upon compliance with the conditions set forth below in this Article.

Section 14.02. Defeasance and Discharge.

Upon the Company’s exercise of the above option applicable to this Section with respect to the Notes, the Company shall be deemed to have been discharged from its obligations with respect to such Outstanding Notes on and after the date the conditions set forth in Section 14.04 are satisfied (hereinafter, “defeasance”). For this purpose, such defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Outstanding Notes, which shall thereafter be deemed to be “Outstanding” only for the purposes of Section 14.05 and the other Sections of this

Indenture referred to in clauses (A) and (B) of this Section, and to have satisfied all its other obligations under the Notes and this Indenture insofar as such Notes are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (A) the rights of Holders of such Outstanding Notes receive, solely from the trust fund described in Section 14.04 and as more fully set forth in such Section, payments in respect of the principal of (and premium, if any) and interest, if any, on the Notes when such payments are due, (B) the Company’s obligations with respect to such Notes under Sections 2.05, 2.07, 4.02 and 4.03, (C) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (D) this Article. Subject to compliance with this Article Fourteen, the Company may exercise its option under this Section notwithstanding the prior exercise of its option under Section 14.03 with respect to such Notes. Following a defeasance, payment of such Notes may not be accelerated because of an Event of Default.

Section 14.03. Covenant Defeasance.

Upon the Company’ s exercise of the above option applicable to this Section with respect to any Notes, the Company shall be released from its obligations under Sections 4.06, 4.07 and 4.08 on and after the date the conditions set forth in Section 14.04 are satisfied (hereinafter, “covenant defeasance”), and such Notes shall thereafter be deemed to be not “Outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection such covenant, but shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to such Outstanding Notes, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such Section or such other covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such Section or such other covenant or by reason of reference in any such Section or such other covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01(a)(3) or otherwise, as the case may be, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. Following a covenant defeasance, payment of such Notes may not be accelerated because of an Event of Default solely by reference to such Sections specified above in this Section 14.03.

be applied by the Trustee (or other qualifying trustee) to pay and discharge, (1) the principal of and interest, if any, on such Outstanding Notes on the Stated Maturity of such principal or installment of principal or interest and (2) any mandatory sinking fund payments or analogous payments applicable to such Outstanding Notes on the day on which such payments are due and payable in accordance with the terms of this Indenture and of such Notes.

(ii)

Such defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under, this Indenture or any other material agreement or instrument to which the Company is a party or by which it is bound.

(iii)

No Default or Event of Default with respect to such Notes shall have occurred and be continuing on the date of such deposit or, insofar as Sections 6.01(a)(4) and 6.01(a)(5) are concerned, at any time during the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period).

Under a Board Resolution, Officers’ Certificate pursuant to Board Resolutions or an indenture supplement, the Company may from time to time, without the consent of the Holders of Securities, issue additional Securities of this series (in any such case “Additional Securities”) having the same ranking and the same interest rate, maturity and other terms as the Securities; provided that, if such Additional Securities are not fungible with the Securities (or any other tranche of Additional Securities for U.S. federal income tax purposes, then such Additional Securities will have a different CUSIP numbers from the Securities (and any such other tranche of Additional Securities). Any Additional Securities and the existing Securities will constitute a single series under the Indenture and all references to the relevant Securities herein shall include the Additional Securities unless the context otherwise requires. The aggregate amount of outstanding Securities represented hereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions.

The Securities of this series are subject to redemption in whole or in part at any time or from time to time, at the option of the Company, on or after September 1, 2025, at a Redemption Price equal to 100% of the outstanding principal amount thereof plus accrued and unpaid interest payments otherwise payable for the then-current quarterly interest period accrued to, but excluding, the Redemption Date.

Notice of redemption shall be given in writing and mailed, first-class postage prepaid or by overnight courier guaranteeing next-day delivery, to each Holder of the Securities to be redeemed, not less than thirty (30) nor more than sixty (60) days prior to the Redemption Date, at the Holder’s address appearing in the Security Register. All notices of redemption shall contain the information set forth in Section 3.02(a) of the Base Indenture.

Any exercise of the Company’s option to redeem the Securities shall be done in compliance with the Indenture and the Investment Company Act, to the extent applicable.

If the Company elects to redeem only a portion of the Securities, the Trustee or, with respect to global Securities, the Depository will determine the method for selecting the particular Securities to be redeemed, in accordance with Section 1.01 of the Fifth Supplemental Indenture and Section 3.02(b) of the Base Indenture. In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest shall cease to accrue on the Securities called for redemption.

Holders of Securities do not have the option to have the Securities repaid prior to September 1, 2028.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security or certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of the Securities at the time Outstanding of each series to be affected.
