In the event that any date on which principal or interest is payable on the New Bonds is not a Business Day (as defined below), the payment of the principal or interest payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay), with the same force and effect as if made on the date the payment was originally payable. “Business Day” means any day, other than a Saturday or Sunday, or a day on which banking institutions or trust companies in The City of New York are generally authorized or required by law, regulation or executive order to remain closed or a day on which the corporate trust office of the Trustee is closed for business.

On or after December 15, 2048 (the date that is six months prior to the maturity date), the New Bonds may be redeemed, at the election of the Company, in the manner provided in Article Ten of the First Mortgage as amended (except as provided below), 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 New Bonds being redeemed, plus accrued and unpaid interest, if any, on the New Bonds to be redeemed to, but excluding, the redemption date.

As used herein, the following defined terms shall have the respective meanings unless the context clearly requires otherwise:

“Treasury Yield” means, with respect to any redemption date, the annual rate equal to the semi-annual equivalent yield to maturity (to December 15, 2048) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date. “Comparable Treasury Issue” means, the United States treasury security selected by an independent investment banker as having a maturity comparable to the time period from the redemption date to the remaining term (to December 15, 2048) of the New Bonds that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term (to December 15, 2048).

“Quotation Agent” means the Reference Treasury Dealer.

“Reference Treasury Dealer” means a primary United States government securities dealer in New York City (a “Primary Treasury Dealer”) appointed by BofA Securities, Inc. or J.P. Morgan Securities LLC and their successors or any other Primary Treasury Dealer appointed by the Company.

“Comparable Treasury Price” means, with respect to any date of redemption: (i) the average of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, on the third business day preceding the redemption date, as set forth in the daily statistical release published by the Federal Reserve Bank of New York and designated “Composite 3:30 p.m. Quotations for U.S. Government Securities,” or (ii) if this release is not published or does not contain such prices on the business day in question, the Reference Treasury Dealer Quotation for the redemption Date.

“Reference Treasury Dealer Quotation” means, with respect to the Reference Treasury Dealer and any redemption date, the average, as determined by the Quotation Agent, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such redemption date.

The Trustee shall have no responsibility for any calculation or determination in respect of the establishment of the redemption price of the New Bonds and shall be entitled to receive and rely conclusively upon a Treasurer’s Certificate that states the redemption price.

Notwithstanding the provisions of Article Ten of the First Mortgage as amended, any notice of redemption given with respect to the New Bonds (i) may provide that if, at the time notice of redemption is given, the redemption monies are not held by the Trustee, the redemption may be made subject to receipt of such monies before the date fixed for redemption, and such notice shall be of no effect and the Company shall not be required to redeem such New Bonds unless such monies are so received, and (ii) will be deemed to be sufficiently given if mailed by or on behalf of the Company at least 20 days and not more than 60 days prior to the date of redemption to each registered holder of such New Bond or New Bonds to be redeemed at his or her last address appearing upon the registry books of the paying agent. Failure duly to mail such notice to the owner or holder of any New Bond designated for redemption in whole or in part shall not affect the validity of the proceedings for the redemption of any other New Bond.

Notwithstanding the provisions of the first and third sentences of Section 4 of Article Ten of the First Mortgage as amended, payment of the redemption price of a portion of any New Bond may, if the Company so agrees with the registered holder thereof (or the person for whom such registered holder is a nominee if such person has filed with the Trustee a certificate to the effect that such registered holder is such person’s nominee), be made by the Trustee, or by any other paying agent with the consent of the Trustee, to such registered holder without presentation or surrender thereof to the Trustee if there shall have been filed with the Trustee a written undertaking of such registered holder, for the benefit of the Trustee and of the Company, that such registered holder (a) will promptly and prior to any transfer make notations on such New Bond of the portions thereof so redeemed and the date to which interest has been paid thereon; (b) will permit the Trustee to inspect, at any reasonable time, such notations (and, in default of such notations having been made, to make such notations); and (c) will not dispose of such New Bond or any interest thereon unless, prior to the delivery thereof, such New Bond either shall have been presented to the Trustee for appropriate notation (or confirmation of notation) thereon of the portion of the principal amount thereof which has been redeemed and the date to which interest has been paid thereon or shall have been surrendered to the Trustee in exchange for a New Bond or New Bonds aggregating the unredeemed balance of the principal amount of such New Bond. The Trustee shall not be under any duty to determine that such notations have been made. The Trustee shall not be liable or responsible to any Bondholder or to the Company or to any person for any act or omission to act on the part of the Company or any Bondholder in connection with the foregoing. The Company will indemnify and save the Trustee harmless against any liabilities resulting from any such act or omission or any action of the Trustee in accordance with this paragraph.

Except as in this Fifty-Second Supplemental Indenture otherwise provided with respect to any matter or question, the provisions of Article Ten of the First Mortgage as amended shall be applicable in the case of the redemption of all or any part of the New Bonds at any time outstanding.

Except as set forth in this Section 5 of Article One of this Fifty-Second Supplemental Indenture, the New Bonds are not redeemable by the Company.

SECTION 6.    Registration Rights for New Bonds. The Company has entered into an Exchange and Registration Rights Agreement dated as of June 6, 2019 (the “Registration Rights Agreement”) with the initial purchasers of the New Bonds pursuant to which, among other things, the New Bonds that are issued without registration (the “Private Bonds”) under the Securities Act of 1933, as amended (the “Securities Act”), may be exchanged for New Bonds that will be registered under the Securities Act and that will otherwise have substantially the same terms as the Private Bonds (the “Exchange Bonds”) or, failing such exchange, the Company will file a shelf registration for the resale of the Private Bonds. The Private Bonds will be offered and sold in reliance on exemptions from, or in transactions not subject to, the Securities Act, and Private Bonds will be exchanged for Exchange Bonds only pursuant to an effective registration statement under the Securities Act and otherwise in accordance with the Registration Rights Agreement and the First Mortgage as amended. Except as provided in the Registration Rights Agreement, nothing in the First Mortgage as amended or the New Bonds shall be construed to require the Company to register any New Bonds under the Securities Act, or to make any transfer of such New Bonds in violation of applicable law. The Private Bonds and the Exchange Bonds will constitute a single series of Bonds under the First Mortgage as amended and this Fifty-Second Supplemental Indenture.

SECTION 7.    Private Bonds. (a) Private Bonds offered and sold in reliance on Rule 144A under the Securities Act shall be issued initially in the form of one or more permanent global New Bonds, substantially in the form of Exhibit A (a “144A Global Security”), deposited with The Depository Trust Company (the “Clearing Agency”) or the Trustee as custodian for the Clearing Agency. Transfers of beneficial interests in the 144A Global Security will be subject to the restrictions on transfer contained in the non-registration legend set forth in Exhibit A. Transfers of beneficial interests in the 144A Global Security will be made in accordance with the standing instructions and procedures of the Clearing Agency.

(a)    Private Bonds offered and sold in offshore transactions in reliance on Regulation S shall be issued initially in the form of one or more permanent global New Bonds, substantially in the form of Exhibit A (a “Regulation S Global Security”), but without the non-registration legend set forth therein, deposited with the Clearing Agency or the Trustee as custodian for the Clearing Agency. Prior to the expiration of the Distribution Compliance Period, transfers of beneficial interests in the Regulation S Global Security will be subject to the restrictions on transfer contained in the Regulation S legend set forth in Exhibit A. After the expiration of the Distribution Compliance Period, transfers of beneficial interests in the Regulation S Global Security will not be subject to any restrictions. Transfers of beneficial interests in the Regulation S Global Security will be made in accordance with the standing instructions and procedures of the Clearing Agency.

For purposes of this Fifty-Second Supplemental Indenture, (i) “Clearing Agency Participant” means a broker, dealer, bank, other financial institution or other person for whom from time to time a Clearing Agency effects book-entry transfers and pledges of securities deposited with the Clearing Agency, (ii) “Distribution Compliance Period” means the period of 40 consecutive days beginning on and including the later of (x) the day on which the offering of the New Bonds commences or (y) the original issue date of the New Bonds, and (iii) “Global Securities Certificate” or “Global Security” means any Private Bond in the form of a 144A Global Security, a Regulation S Global Security and, if applicable, any Exchange Bond represented in global form and deposited with the Clearing Agency or the Trustee as custodian for the Clearing Agency.

(b)    Exchange Bonds shall be issued in global form, substantially in the form, and bearing the legends, set forth in Exhibit B, deposited with the Clearing Agency or the Trustee as custodian for the Clearing Agency.

SECTION 8.    Transfers of New Bonds. (a) So long as the Private Bonds are eligible for book-entry settlement in the Clearing Agency or unless otherwise required by law, all Private Bonds that are so eligible will be represented by one or more Global Securities Certificates deposited with the Clearing Agency or the Trustee as custodian for the Clearing Agency. No owner of a beneficial interest in a Global Securities Certificate will receive a Definitive New Bond Certificate representing such owner’s beneficial interest in the Private Bonds, except as provided in Section 8(f) of this Article One; provided, however, that the Company shall issue a Definitive New Bond Certificate upon any transfer of a beneficial interest in a Global Security to the Company or an “affiliate” as defined in Rule 144 under the Securities Act (an “Affiliate”) of the Company and no Definitive New Bond Certificate, or portion thereof, in respect of which the Company or an Affiliate of the Company held any beneficial interest shall be resold, retransferred or included in any Global Security until such Private Bond is freely tradeable in accordance with Rule 144 under the Securities Act or exchanged for an Exchange Bond.

For purposes of this Fifty-Second Supplemental Indenture, “Definitive New Bond Certificates” means New Bonds issued in definitive, fully registered form, substantially in the form of Exhibit A, but without the depository legend and the Regulation S legend set forth therein.

(a)    Global Securities shall initially be registered in the name of a nominee of the Clearing Agency.

(b)    Transfers of interests in Private Bonds between any 144A Global Security and any Regulation S Global Security will be made in accordance with this Fifty-Second Supplemental Indenture (including Section 8(d)(iii) and (iv) of this Article One, as applicable) and in accordance with the standing instructions and procedures of the Clearing Agency. The Trustee shall make appropriate endorsements to reflect increases or decreases in the amount of such Global Securities.

(c)    Unless and until the earlier of (i) the date upon which Private Bonds are exchanged for Exchange Bonds in connection with an effective registration statement pursuant to the Registration Rights Agreement or (ii) the Transfer Restriction Termination Date (meaning

the first day in which the New Bonds (other than New Bonds acquired by the Company or any Affiliate thereof) may be sold pursuant to Rule 144 under the Securities Act):

(i)    Definitive to Definitive Transfers. Any transfer of a Definitive New Bond Certificate shall be registered on the registry books only upon receipt by the Trustee of such Definitive New Bond Certificate accompanied by a duly completed and executed assignment in a form reasonably acceptable to the Trustee and such other certifications, legal opinions or other information as the Company may reasonably request to confirm that such transfer is exempt from the registration requirements of the Securities Act;

(ii)    Definitive into Global Security. So long as Private Bonds are eligible for book-entry settlement with the Clearing Agency or unless otherwise required by law, upon any transfer of a Definitive New Bond Certificate to a Qualified Institutional Buyer in accordance with Rule 144A under the Securities Act or to a non-U.S. Person in accordance with Regulation S, and upon receipt of the Definitive New Bond Certificate being so transferred, the Trustee shall make an endorsement on any 144A Global Security or any Regulation S Global Security, as the case may be, to reflect an increase in such Global Security and the Trustee shall cancel such Definitive New Bond Certificate;

(iii)    144A Global Security into Regulation S Global Security. Any transfer in accordance with Rule 903 or Rule 904 of Regulation S of a beneficial interest in a 144A Global Security shall be reflected by an increase in the Regulation S Global Security and a corresponding decrease in the 144A Global Security, in each case by the Trustee making an endorsement on such Global Security, only upon receipt by the Trustee of a written certificate in the form of Exhibit C (or such other certifications, legal opinions or other information as the Company may reasonably require to confirm that such transfer is being made pursuant to such Rule 903 or Rule 904); and

(iv)    Regulation S Global Security into 144A Global Security. Any transfer of a beneficial interest in a Regulation S Global Security to a transferee that takes delivery in the form of a beneficial interest in the 144A Global Security shall be reflected by an increase in the 144A Global Security and a corresponding decrease in the Regulation S Global Security, in each case by the Trustee making an endorsement on such Global Security and, prior to the expiration of the Distribution Compliance Period, only upon receipt by the Trustee of a written certificate in the form of Exhibit D (or such other certifications, legal opinions or other information as the Company may reasonably require).

(d)    Any Global Security may be endorsed with or have incorporated in the text thereof such legends or recitals or changes not inconsistent with the provisions of this Fifty-Second Supplemental Indenture and the First Mortgage as amended as may be required by the Clearing Agency, by any national securities exchange or by the Financial Industry Regulatory Authority, Inc. or as may be required for the Private Bonds to be tradable on any other market

developed for trading of securities pursuant to Rule 144A under the Securities Act or required to comply with any applicable law or any regulation thereunder or with the rules and regulations of any securities exchange upon which the New Bonds may be listed or traded or to conform with any usage with respect thereto, or to indicate any special limitations or restrictions to which any particular New Bonds are subject.

(e)    Notwithstanding any other provisions of this Fifty-Second Supplemental Indenture (other than the provisions set forth in this Section 8(f)), a Global Security may not be exchanged in whole or in part for Definitive New Bond Certificates, and no transfer of a Global Security may be registered, in the name of any person other than the Clearing Agency or a nominee thereof unless (i) such Clearing Agency (A) has notified the Trustee and the Company that it is unwilling or unable to continue as Clearing Agency for such Global Security or (B) has ceased to be a clearing agency registered as such under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and no successor Clearing Agency has been appointed by the Company within 90 days after its receipt of such notice or its becoming aware of such cessation of registration, (ii) there has occurred and is continuing an Event of Default, or any event that after notice or lapse of time or both would be an Event of Default under the First Mortgage as amended, with respect to the New Bonds or (iii) the Company in its discretion instructs the Trustee to exchange such Global Security for Definitive New Bond Certificates (in which case such exchange shall be effected by the Trustee).

(f)    Unless and until Definitive New Bond Certificates have been issued to owners pursuant to Section 10 of this Article One, the following provisions of this Section 8(g) shall be in full force and effect:

(i)    the security registrar and the Trustee shall be entitled to deal with the Clearing Agency for all purposes of this Fifty-Second Supplemental Indenture relating to the Global Securities (including the payment of principal, premium, if any, and interest on the New Bonds evidenced by Global Securities Certificates and the giving of instructions or directions to owners of New Bonds evidenced by Global Securities) as the sole holder of New Bonds evidenced by Global Securities and shall have no obligations to the beneficial owners thereof; and

(ii)    the rights of the beneficial owners of the Global Securities shall be exercised only through the Clearing Agency and shall be limited to those established by law and agreements between such beneficial owners and the Clearing Agency and/or the Clearing Agency Participants. Unless and until Definitive New Bond Certificates are issued pursuant to Section 8(f) of this Article One or Section 10 of this Article One, the initial Clearing Agency will make book-entry transfers among the Clearing Agency Participants and receive and transmit payments on the New Bonds to such Clearing Agency Participants.

(g)    The Company shall inform the Trustee of the effective date of any registration statement registering the Exchange Bonds or the Private Bonds under the Securities Act. Upon the receipt of a request in writing from the Company, the Trustee will take such actions as shall be necessary to effectuate the exchange of any of the Private Bonds for Exchange Bonds,

including but not limited to the issuance of Exchange Bonds in the form substantially set forth in Exhibit B, the entry of decreases in the Regulation S Global Security and the 144A Global Security or, if applicable, the cancellation of any Definitive New Bond Certificates.

SECTION 9.    Notices. To the extent that a notice or other communication to the beneficial owners is required under this Fifty-Second Supplemental Indenture, unless and until Definitive New Bond Certificates shall have been issued to beneficial owners pursuant to Section 10 of this Article One, the Trustee shall give all such notices and communications specified herein to be given to beneficial owners to the Clearing Agency, and shall have no obligations to the beneficial owners.

SECTION 10.    Definitive New Bond Certificates. Upon surrender to the security registrar of the Global Securities Certificates by the Clearing Agency upon occurrence of any of the events described in Section 8(f) of this Article One, accompanied by registration instructions, the Trustee shall authenticate and deliver and the security registrar shall register the Definitive New Bond Certificates in accordance with the instructions of the Clearing Agency. Neither the security registrar nor the Trustee shall be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such instructions. Upon the issuance of Definitive New Bond Certificates, the Trustee shall recognize the holders of the Definitive New Bond Certificates as Bondholders.

SECTION 11.    Beneficial Interests in Global Security. Any beneficial interest in one of the Global Securities that is transferred to a person who takes delivery in the form of an interest in the other Global Security will, upon transfer, cease to be an interest in such Global Security and become an interest in the other Global Security and, accordingly, will thereafter be subject to all restrictions, if any, and procedures applicable to beneficial interests in such other Global Security for as long as it remains such an interest.

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Fifty-Second Supplemental Indenture, the New Bonds or applicable law with respect to any transfer or any interest in any New Bond (including any transfers between or among the Clearing Agency Participants or owners or holders of beneficial interests in any Global Security) other than to require delivery of such certificates and other documentation or evidence, if any, as are expressly required by, and to do so if and when expressly required by the terms of, this Fifty-Second Supplemental Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

None of the Company, the Trustee, any paying agent or the security registrar shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in any Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

No holder of any beneficial interest in any Global Security held on its behalf by the Clearing Agency (or its nominee) shall have any rights under this Fifty-Second Supplemental Indenture with respect to such Global Security or any New Bond represented thereby, and the Clearing Agency may be treated by the Company, the Trustee, and any agent of the Company or the Trustee as the owner of such Global Security or any New Bond represented thereby for all purposes whatsoever.

Notwithstanding the foregoing, with respect to any Global Security, nothing herein shall prevent the Company, the Trustee, or any agent of the Company or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by the Clearing Agency, as a holder, with respect to such Global Security or shall impair, as between the Clearing Agency and owners of beneficial interests in such Global Security, the operation of customary practices governing the exercise of the rights of the Clearing Agency (or its nominee) as holder of such Global Security.

SECTION 12.    Defeasance. (a) Any New Bonds, or any portion of the principal amount thereof, will be deemed to have been paid for all purposes of the First Mortgage as amended and this Fifty-Second Supplemental Indenture and the entirety of the Company’s indebtedness in respect thereof will be deemed to have been satisfied and discharged, if there has been irrevocably deposited with the Trustee or any paying agent (other than the Company) for such purpose, in trust:

(iii)    a combination of options in the preceding clauses (i) and (ii),

which in each case, will be sufficient, without reinvestment, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants expressed in a written certification delivered to the Trustee, to pay when due the principal of and premium, if any, and interest, if any, due and to become due on such New Bonds or portions thereof.

(b)    In this Fifty-Second Supplemental Indenture, “eligible obligations” include direct obligations of, or obligations unconditionally guaranteed by, the United States of America, entitled to the benefit of the full faith and credit thereof, and certificates, depository receipts or other instruments, which may be issued by the Trustee that evidence a direct ownership interest in such obligations or in any specific interest or principal payments due in respect thereof.

(c)    Notwithstanding the foregoing, no New Bond shall be deemed to have been paid as aforesaid unless the Company shall have delivered to the Trustee either:

(i)    an opinion of counsel in the United States who is reasonably acceptable to the Trustee confirming that (i) the Company has received

from, or there has been published by, the Internal Revenue Service a ruling or (ii) since June 3, 2019, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion of counsel shall confirm that, the holders of the outstanding New Bonds will not recognize income, gain or loss for federal income tax purposes as a result of such defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred; or

(ii)    (A) an instrument wherein the Company, notwithstanding the satisfaction and discharge of its indebtedness in respect of New Bonds, shall assume the obligation (which shall be absolute and unconditional) to irrevocably deposit with the Trustee such additional sums of money, if any, or additional eligible obligations, if any, or any combination thereof, at such time or times, as shall be necessary, together with the money and/or eligible obligations theretofore so deposited, to pay when due the principal of and premium, if any, and interest due and to become due on such New Bonds or portions thereof; provided, however, that such instrument may state that the Company’s obligation to make additional deposits as aforesaid shall be subject to the delivery to the Company by a holder of a New Bond of a notice asserting the deficiency accompanied by an opinion of an independent public accountant of nationally recognized standing showing the calculation thereof; and (B) an opinion of tax counsel in the United States who is reasonably acceptable to the Trustee to the effect that the holders of the outstanding New Bonds will not recognize income, gain or loss for federal income tax purposes as a result of such defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred.
