9

The Company further covenants and agrees to and with the Trustees and their successor or successors in such trust under the Mortgage as follows:

ARTICLE I

NINETY-SEVENTH SERIES OF BONDS

SECTION 1.  (A) There shall be a series of bonds designated “3.25% Series due 2025” (herein sometimes referred to as the “Ninety-seventh Series”), each of which shall also bear the descriptive title “First Mortgage Bond”, and the form thereof, which shall be established by Resolution of the Board of Directors of the Company, shall contain suitable provisions with respect to the matters hereinafter in this Section specified. Bonds of the Ninety-seventh Series shall be initially issued in the aggregate principal amount of $500,000,000, mature on August 15, 2025, bear interest at the rate of 3.25% per annum, payable from August 13, 2015, if the date of said bonds is on or prior to February 15, 2016, or, if the date of said bonds is after February 15, 2016, from the February 15 or August 15 next preceding the date of said bonds, semi-annually on February 15 and August 15 of each year commencing on February 15, 2016, be issued as fully registered bonds in the denominations of Two Thousand Dollars and in any integral multiple of One Thousand Dollars in excess thereof and be dated as in Section 10 of the Mortgage provided, the principal of and interest on each said bond to be payable at the office or agency of the Company in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for public and private debts.

Interest on bonds of the Ninety-seventh Series will be computed on the basis of a 360-day year comprised of twelve 30-day months. If a due date for the payment of interest, principal or any Redemption Price (as defined below) on the bonds of the Ninety-seventh Series, falls on a day that is not a Business Day, then the payment will be made on the next succeeding Business Day, and no interest will accrue on the amounts payable for the period from and after the original due date and until the next Business Day. The term “Business Day” means any day other than a Saturday or Sunday or day on which banking institutions in The City of New York are required or authorized to close.

(B)                               At any time on or after May 15, 2025, the bonds of the Ninety-seventh Series shall be redeemable at the option of the Company, or with the Proceeds of Released Property (as contemplated by clause (4) of Section 61 of the Mortgage), in whole or in part and from time to time, prior to maturity, upon notice as provided in Sections 52 and 54 of the Mortgage (given by mail or, if the bonds of the Ninety-seventh Series are represented by one or more Ninety-seventh Series Global Bonds (as hereinafter defined),  given in accordance with the procedures of DTC (as hereinafter defined), not less than 30 days and not more than 90 days prior to the date fixed for redemption), at a redemption price equal to 100% of the principal amount of the bonds then Outstanding to be redeemed, plus in each case accrued but unpaid interest on such principal amount to, but excluding, such date fixed for redemption. At any time prior to May 15, 2025, the bonds of the Ninety-seventh Series shall be redeemable at the option of the Company, or with the Proceeds of Released Property (as contemplated by clause (4) of Section 61 of the Mortgage), in whole or in part and from time to time, upon notice as provided in Sections 52 and 54 of the Mortgage (given by mail or, if the bonds of the Ninety-seventh Series are represented by one or more Ninety-seventh Series Global Bonds (as hereinafter defined),  given in accordance with the procedures of DTC (as hereinafter defined), not less than 30 days and not more than 90 days prior to the date fixed for redemption (together with the date fixed for redemption referred to in the preceding sentence, each a “Redemption Date”)), at a redemption price (hereinafter sometimes referred to as the “Make-Whole Redemption Price” and, together with the redemption price referred to in the preceding sentence, each a “Redemption Price”) equal to the greater of (i) 100% of the principal amount of the bonds then Outstanding to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on such bonds being redeemed that would be due if such bonds matured on May

10

15, 2025, computed by discounting such payments, in each case, to such Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 20 basis points, plus in either case accrued but unpaid interest on such principal amount to, but excluding, such Redemption Date. On and after any Redemption Date, if sufficient cash shall have been deposited with the Corporate Trustee (and/or if the Company has irrevocably directed the Corporate Trustee to apply, from moneys held by it available to be used for the redemption of bonds, sufficient cash) to redeem all of the bonds of the Ninety-seventh Series called for redemption, interest on the bonds of the Ninety-seventh Series, or the portions of them so called for redemption, shall cease to accrue.

“Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent yield to maturity or interpolated maturity (on a day count basis) 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 the Quotation Agent as having an actual or interpolated maturity comparable to the remaining term of the bonds of the Ninety-seventh Series to be redeemed (assuming, for this purpose, that the bonds of the Ninety-seventh Series matured on May 15, 2025), 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 a comparable maturity to the remaining term of such bonds of the Ninety-seventh Series.

“Comparable Treasury Price” means, with respect to any Redemption Date, (A) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (B) if the Quotation Agent obtains fewer than four of such Reference Treasury Dealer Quotations, the average of all such quotations.

“Quotation Agent” means one of the Reference Treasury Dealers appointed by the Company.

“Reference Treasury Dealer” means each of Credit Suisse Securities (USA) LLC, RBC Capital Markets, LLC, UBS Securities LLC, a Primary Treasury Dealer (as defined below) selected by SunTrust Robinson Humphrey, Inc. and a Primary Treasury Dealer selected by Wells Fargo Securities, LLC, or their respective affiliates or successors, each of which is a primary U.S. Government securities dealer in the United States (a “Primary Treasury Dealer”); provided, however, that if any of the foregoing or their affiliates or successors shall cease to be a Primary Treasury Dealer, the Company shall substitute therefor another Primary Treasury Dealer.

“Reference Treasury Dealer Quotations” means, with respect to each 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 Quotation Agent by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date.

In case of a redemption of only a part of the bonds of the Ninety-seventh Series, absent any written agreement of the registered holders of all of the bonds of the Ninety-seventh Series satisfactory to the Corporate Trustee specifying the particular bonds of the Ninety-seventh Series to be redeemed, the Corporate Trustee shall draw by lot, according to such method as it shall deem proper in its discretion, the particular bonds of the Ninety-seventh Series, or portions of them, to be redeemed, provided, that if the bonds of the Ninety-seventh Series are represented by one or more Ninety-seventh Series Global Bonds, interests in the bonds of the Ninety-seventh Series shall be selected for redemption by DTC in accordance with its standard procedures therefor.

11

In case of any bonds of the Ninety-seventh Series called for redemption in whole or in part prior to May 15, 2025, the Company shall deliver to the Corporate Trustee promptly upon its calculation thereof, but in any event prior to the related Redemption Date, a Treasurer’s Certificate setting forth its calculation of the Make-Whole Redemption Price applicable to such redemption. The Corporate Trustee shall be under no duty to inquire into, may conclusively presume the correctness of, and shall be fully protected in relying upon the Company’s calculation of any Make-Whole Redemption Price of the bonds of the Ninety-seventh Series.

In lieu of stating any Make-Whole Redemption Price, notices of redemption of the bonds of the Ninety-seventh Series called for redemption in whole or in part shall state substantially the following: “The redemption price of the bonds to be redeemed shall equal the greater of (i) 100% of the principal amount of the bonds then Outstanding to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon that would be due if such bonds matured on May 15, 2025, computed by discounting such payments, in each case, to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined in the Eighty-fifth Supplemental Indenture) plus 20 basis points, plus in each case accrued but unpaid interest on the principal amount thereof called for redemption to, but excluding, the Redemption Date.”

Except as provided herein, Article X of the Mortgage shall apply to redemptions of bonds of the Ninety-seventh Series.

(C)                               Subject to the provisions set forth below with respect to Ninety-seventh Series Global Bonds, at the option of the registered owner, any bonds of the Ninety-seventh Series, upon surrender thereof for cancellation at the office or agency of the Company in the Borough of Manhattan, The City of New York, shall be exchangeable for a like aggregate principal amount of bonds of the same series of other authorized denominations. The bonds of the Ninety-seventh Series may bear such legends as may be necessary to comply with any law or with any rules or regulations made pursuant thereto or with the rules or regulations of any stock exchange or to conform to usage or agreement with respect thereto.

Subject to the provisions set forth below with respect to Ninety-seventh Series Global Bonds, bonds of the Ninety-seventh Series shall be transferable upon the surrender thereof for cancellation, together with a written instrument of transfer in form approved by the registrar duly executed by the registered owner or by his duly authorized attorney, at the office or agency of the Company in the Borough of Manhattan, The City of New York.

Upon any exchange or transfer of bonds of the Ninety-seventh Series, the Company may make a charge therefor sufficient to reimburse it for any tax or taxes or other governmental charge required to be paid by the Company, as provided in Section 12 of the Mortgage, but the Company hereby waives any right to make a charge in addition thereto for any exchange or transfer of bonds of said Series.

(D)                               The bonds of the Ninety-seventh Series shall be issued in registered form without coupons and shall be issued initially in the form of one or more global bonds (each such global bond hereinafter sometimes referred to as a “Ninety-seventh Series Global Bond”) to or on behalf of The Depository Trust Company (hereinafter sometimes referred to as “DTC”), as depositary therefor, and registered in the name of such depositary or its nominee. Any bonds of the Ninety-seventh Series to be issued or transferred to, or to be held by or on behalf of DTC as such depositary or such nominee (or any successor of such depositary or nominee) for such purpose shall bear the depositary legends as required or otherwise agreed to by the Corporate Trustee and the Company, and in the case of a successor depositary, such legend or legends as such depositary and/or the Company shall require and to which each shall agree, in each case such agreement to be confirmed in writing to the Corporate Trustee. Notwithstanding

12

any other provision in this Eighty-fifth Supplemental Indenture, payment of interest on the bonds of the Ninety-seventh Series may be made at the option of the Company by check mailed to the registered holders thereof at their registered address, and, with respect to a Ninety-seventh Series Global Bond, the Company may make payments of principal of, any Redemption Price and interest on such Ninety-seventh Series Global Bond pursuant to and in accordance with such arrangements as are agreed upon by the Company and the depositary for such Ninety-seventh Series Global Bond.

Except under the limited circumstances described below, bonds of the Ninety-seventh Series represented by a Ninety-seventh Series Global Bond or Bonds shall not be exchangeable for, and shall not otherwise be issuable as, bonds of the Ninety-seventh Series in definitive form.

Interest on bonds of the Ninety-eighth Series will be computed on the basis of a 360-day year comprised of twelve 30-day months. If a due date for the payment of interest, principal or any Redemption Price (as defined below) on the bonds of the Ninety-eighth Series, falls on a day that is not a Business Day, then the payment will be made on the next succeeding Business Day, and no interest will accrue on the amounts payable for the period from and after the original due date and until the next Business Day.

(B)                               At any time on or after February 15, 2045, the bonds of the Ninety-eighth Series shall be redeemable at the option of the Company, or with the Proceeds of Released Property (as contemplated by clause (4) of Section 61 of the Mortgage), in whole or in part and from time to time, prior to maturity, upon notice as provided in Sections 52 and 54 of the Mortgage (given by mail or, if the bonds of the Ninety-eighth Series are represented by one or more Ninety-eighth Series Global Bonds (as hereinafter defined), given in accordance with the procedures of DTC, not less than 30 days and not more than 90 days prior to the date fixed for redemption), at a redemption price equal to 100% of the principal amount of the bonds then Outstanding to be redeemed, plus in each case accrued but unpaid interest on such principal amount to, but excluding, such date fixed for redemption. At any time prior to February 15, 2045, the bonds of the Ninety-eighth Series shall be redeemable at the option of the Company, or with the Proceeds of Released Property (as contemplated by clause (4) of Section 61 of the Mortgage), in whole or in part and from time to time, upon notice as provided in Sections 52 and 54 of the Mortgage (given by mail or, if the bonds of the Ninety-eighth Series are represented by one or more Ninety-eighth Series Global Bonds (as hereinafter defined), given in accordance with the procedures of DTC, not less than 30 days and not more than 90 days prior to the date fixed for redemption (together with the date fixed for redemption referred to in the preceding sentence, each a “Redemption Date”)), at a redemption price (hereinafter sometimes referred to as the “Make-Whole Redemption Price” and, together with the redemption price referred to in the preceding sentence, each a “Redemption Price”) equal to the greater of (i) 100% of the principal amount of the bonds then Outstanding to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on such bonds being redeemed that would be due if such bonds matured on February 15, 2045, computed by discounting such payments, in each case, to such Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 20 basis points, plus in either case accrued but unpaid interest on such principal amount to, but excluding, such Redemption Date. On and after any Redemption Date, if sufficient cash shall have been deposited with the Corporate Trustee (and/or if the Company has irrevocably directed the Corporate Trustee to apply, from moneys held by it available to be used for the redemption of bonds, sufficient cash) to redeem all of the bonds of the Ninety-eighth Series called for redemption, interest on the bonds of the Ninety-eighth Series, or the portions of them so called for redemption, shall cease to accrue.

“Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent yield to maturity or interpolated maturity (on a day count basis) 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 the Quotation Agent as having an actual or interpolated maturity comparable to the remaining term of the bonds of the Ninety-eighth Series to be redeemed (assuming, for this purpose, that the bonds of the Ninety-eighth Series matured on February 15, 2045), 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 a comparable maturity to the remaining term of such bonds of the Ninety-eighth Series.

“Comparable Treasury Price” means, with respect to any Redemption Date, (A) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (B) if the Quotation Agent obtains fewer than four of such Reference Treasury Dealer Quotations, the average of all such quotations.

“Quotation Agent” means one of the Reference Treasury Dealers appointed by the Company.

“Reference Treasury Dealer” means each of Credit Suisse Securities (USA) LLC, RBC Capital Markets, LLC, UBS Securities LLC, a Primary Treasury Dealer (as defined below) selected by SunTrust

“Reference Treasury Dealer Quotations” means, with respect to each 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 Quotation Agent by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date.

In case of a redemption of only a part of the bonds of the Ninety-eighth Series, absent any written agreement of the registered holders of all of the bonds of the Ninety-eighth Series satisfactory to the Corporate Trustee specifying the particular bonds of the Ninety-eighth Series to be redeemed, the Corporate Trustee shall draw by lot, according to such method as it shall deem proper in its discretion, the particular bonds of the Ninety-eighth Series, or portions of them, to be redeemed, provided, that if the bonds of the Ninety-eighth Series are represented by one or more Ninety-eighth Series Global Bonds, interests in the bonds of the Ninety-eighth Series shall be selected for redemption by DTC in accordance with its standard procedures therefor.

In case of any bonds of the Ninety-eighth Series called for redemption in whole or in part prior to February 15, 2045, the Company shall deliver to the Corporate Trustee promptly upon its calculation thereof, but in any event prior to the related Redemption Date, a Treasurer’s Certificate setting forth its calculation of the Make-Whole Redemption Price applicable to such redemption. The Corporate Trustee shall be under no duty to inquire into, may conclusively presume the correctness of, and shall be fully protected in relying upon the Company’s calculation of any Make-Whole Redemption Price of the bonds of the Ninety-eighth Series.

In lieu of stating any Make-Whole Redemption Price, notices of redemption of the bonds of the Ninety-eighth Series called for redemption in whole or in part shall state substantially the following: “The redemption price of the bonds to be redeemed shall equal the greater of (i) 100% of the principal amount of the bonds then Outstanding to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon being redeemed that would be due if such bonds matured on February 15, 2045, computed by discounting such payments, in each case, to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined in the Eighty-fifth Supplemental Indenture) plus 20 basis points, plus in each case accrued but unpaid interest on the principal amount thereof called for redemption to, but excluding, the Redemption Date.”

Except as provided herein, Article X of the Mortgage shall apply to redemptions of bonds of the Ninety-eighth Series.

(C)                               Subject to the provisions set forth below with respect to Ninety-eighth Series Global Bonds, at the option of the registered owner, any bonds of the Ninety-eighth Series, upon surrender thereof for cancellation at the office or agency of the Company in the Borough of Manhattan, The City of New York, shall be exchangeable for a like aggregate principal amount of bonds of the same series of other authorized denominations.

Upon any exchange or transfer of bonds of the Ninety-eighth Series, the Company may make a charge therefor sufficient to reimburse it for any tax or taxes or other governmental charge required to be paid by the Company, as provided in Section 12 of the Mortgage, but the Company hereby waives any right to make a charge in addition thereto for any exchange or transfer of bonds of said Series.

(D)                               The bonds of the Ninety-eighth Series shall be issued in registered form without coupons and shall be issued initially in the form of one or more global bonds (each such global bond hereinafter sometimes referred to as a “Ninety-eighth Series Global Bond”) to or on behalf of The Depository Trust Company (hereinafter sometimes referred to as “DTC”), as depositary therefor, and registered in the name of such depositary or its nominee.

The laws of South Carolina provide that in any real estate foreclosure proceeding a defendant against whom a personal judgment is taken or asked may within thirty days after the sale of the mortgaged property apply to the court for an order of appraisal.

or registered assigns, at the office or agency of the Company in the Borough of Manhattan, The City of New York,

FIVE HUNDRED MILLION DOLLARS ($500,000,000)

on August 15, 2025, in such coin or currency of the United States of America as at the time of payment is legal tender for public and private debts, and to pay to the registered owner hereof interest thereon from August 13, 2015, if the date of this bond is on or prior to February 15, 2016, or, if the date of this bond is after February 15, 2016, from the February 15 or August 15 next preceding the date of this bond, at the rate of 3.25% per annum (with interest on overdue principal and overdue installments of interest payable in accordance with the terms of the Mortgage (as hereinafter defined)) in like coin or currency semi-annually at said office or agency, on February 15 and August 15 in each year until the principal of this bond shall have become due and payable (each an “Interest Payment Date”). If the date of this bond is on or prior to February 15, 2016, such payments shall commence on February 15, 2016.  Interest on this bond will be computed on the basis of a 360-day year comprised of twelve 30-day months.

Any interest on this bond which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the person in whose name this bond (or one or more predecessor bonds) is registered at the close of business on the tenth calendar day next preceding such Interest Payment Date (i.e., February 5 and August 5, respectively) (each a “Regular Record Date”), provided, however, that so long as this bond is registered in the name of The Depository Trust Company, a New York corporation, its nominee or a successor depositary, the Regular Record Date shall be the close of business on the business day (as defined in the Eighty-fifth Supplemental Indenture mentioned below) immediately preceding such Interest Payment Date.

Any interest on this bond which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date shall forthwith cease to be payable to the registered holder on the relevant Regular Record Date solely by virtue of such holder having been such holder; and such interest, together with any interest thereon as provided in the Mortgage (collectively, “Defaulted Interest”), may be paid by the Company, at its election in each case, as provided in Subsection A or B below:

A.            The Company may elect to make payment of any Defaulted Interest on the bonds of this series (as defined below) to the persons in whose names such bonds (or their respective predecessor bonds) are registered at the close of business on a special record date for the payment of such Defaulted Interest, which shall be fixed in the following manner (a “Special Record Date”). The Company shall notify the Corporate Trustee referred to below in writing of the amount of Defaulted Interest proposed to be paid on each bond and the date of the proposed payment (which date shall be such as will enable the Corporate Trustee to comply with the next two sentences hereof), and at the same time the Company shall deposit with the Corporate Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Corporate Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the persons entitled to such Defaulted Interest as in this Subsection provided and not to be deemed otherwise part of the trust estate or trust moneys. Thereupon the Corporate Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 or less than 10 days prior to the date of the proposed payment and not less than

10 days after the receipt by the Corporate Trustee of the notice of the proposed payment. The Corporate Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each holder of a bond of this series at such holder’s address as it appears in the bond register not less than 10 days prior to such Special Record Date. The Corporate Trustee may, in its discretion in the name and at the expense of the Company, cause a similar notice to be published at least once in a newspaper approved by the Company in each place of payment of the bonds of this series, but such publication shall not be a condition precedent to the establishment of such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the persons in whose names the bonds of this series (or their respective predecessor bonds) are registered on such Special Record Date and shall no longer be payable pursuant to the following Subsection B.

B.            The Company may make payment of any Defaulted Interest on the bonds of this series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such bonds may be listed and upon such notice as may be required by such exchange, if, after notice given by the Company to the Corporate Trustee of the proposed payment pursuant to this Subsection, such payment shall be deemed practicable by the Corporate Trustee.

Subject to the foregoing, each bond of this series delivered under the Mortgage hereinafter mentioned upon transfer of or in exchange for or in lieu of any other bond of this series shall carry all the rights to interest accrued and unpaid, and to accrue, which were carried by such other bond.

With the consent of the Company and to the extent permitted by and as provided in the Mortgage, the rights and obligations of the Company and/or the rights of the holders of the bonds and/or coupons and/or the terms and provisions of the Mortgage may be modified or altered by affirmative vote of the holders of at least 66 2/3% in principal amount of the bonds then outstanding under the Mortgage and, if the rights of one or more, but less than all, series of bonds then outstanding are to be affected, then also by affirmative vote of the holders of at least 66 2/3% in principal amount of the bonds then outstanding of each series of bonds so to be affected (excluding in any case bonds disqualified from voting by reason of the Company’s interest therein as provided in the Mortgage); provided that, without the consent of the holder hereof, no such modification or alteration, among other things, shall impair or affect the right of the holder to receive payment of the principal of and interest on this bond, on or after the respective due dates expressed herein, or permit the creation of any lien equal or prior to the lien of the Mortgage or deprive the holder of a lien on the mortgaged and pledged property.

The principal hereof may be declared or may become due prior to the maturity date hereinbefore named on the conditions, in the manner and at the time set forth in the Mortgage, upon the occurrence of a default as in the Mortgage provided.

This bond is transferable as prescribed in the Mortgage by the registered owner hereof in person, or by his duly authorized attorney, at the office or agency of the Company in the Borough of Manhattan, The City of New York, upon surrender and cancellation of this bond, and thereupon a new fully registered temporary or definitive bond of the same series for a like principal amount will be issued to the transferee in exchange herefor as provided in the Mortgage. The Company and the Trustees may deem and treat the person in whose name this bond is registered as the absolute owner hereof for the purpose of receiving payment and for all other purposes.

In the manner prescribed in the Mortgage, any bonds of this series, upon surrender thereof for cancellation at the office or agency of the Company in the Borough of Manhattan, The City of New York, are exchangeable for a like aggregate principal amount of bonds of the same series of other authorized denominations.

At any time on or after May 15, 2025, the bonds of this series shall be redeemable at the option of the Company, in whole or in part and from time to time, prior to maturity, upon notice as provided in the Mortgage (given not less than 30 days and not more than 90 days prior to the date fixed for redemption), at a redemption price equal to 100% of the principal amount of the bonds then outstanding to be redeemed, plus in each case accrued interest on such principal amount to, but excluding, such date fixed for redemption. At any time prior to May 15, 2025, the bonds of this series shall be redeemable at the option of the Company, in whole or in part and from time to time, upon notice as provided in the Mortgage (given not less than 30 days and not more than 90 days prior to the date fixed for redemption (together with the date fixed for redemption referred to in the preceding sentence, each a “Redemption Date”)), at a redemption price (together with the redemption price referred to in the preceding sentence, each a “Redemption Price”) equal to the greater of (i) 100% of the principal amount of the bonds then outstanding to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on such bonds being redeemed that would be due if such bonds matured on May 15, 2025, computed by discounting such payments, in each case, to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined in the Eighty-fifth Supplemental Indenture mentioned above) plus 20 basis points, plus in either case accrued but unpaid interest on such principal amount to, but excluding, the Redemption Date.  On and after any Redemption Date, if sufficient cash shall have been deposited with Corporate Trustee (and/or if the Company has irrevocably directed the Corporate Trustee to apply, from moneys held by it available to be used for the redemption of bonds, sufficient cash) to redeem all of the bonds of this series called for redemption, interest on the bonds of this series, or the portions of them so called for redemption, shall cease to accrue. Reference is made to said Eighty-fifth Supplemental Indenture for the full terms of the redemption provisions applicable to the bonds of this series.

No recourse shall be had for the payment of the principal or any Redemption Price of or interest on this bond against any incorporator or any past, present or future subscriber to the capital stock, stockholder, officer or director of the Company or of any predecessor or successor corporation, as such, either directly or through the Company or any predecessor or successor corporation, under any rule of law, statute or constitution or by the enforcement of any assessment or otherwise, all such liability of incorporators, subscribers, stockholders, officers and directors being released by the holder or owner hereof by the acceptance of this bond and being likewise waived and released by the terms of the Mortgage.

If the date of this bond is on or prior to February 15, 2016, such payments shall commence on February 15, 2016.  Interest on this bond will be computed on the basis of a 360-day year comprised of twelve 30-day months.

Any interest on this bond which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the person in whose name this bond (or one or more predecessor bonds) is registered at the close of business on the tenth calendar day next preceding such Interest Payment Date (i.e., February 5 and August 5, respectively) (each a “Regular Record Date”), provided, however, that so long as this bond is registered in the name of The Depository Trust Company, a New York corporation, its nominee or a successor depositary, the Regular Record Date shall be the close of business on the business day (as defined in the Eighty-fifth Supplemental Indenture mentioned below) immediately preceding such Interest Payment Date.

Any interest on this bond which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date shall forthwith cease to be payable to the registered holder on the relevant Regular Record Date solely by virtue of such holder having been such holder; and such interest, together with any interest thereon as provided in the Mortgage (collectively, “Defaulted Interest”), may be paid by the Company, at its election in each case, as provided in Subsection A or B below:

A.                                    The Company may elect to make payment of any Defaulted Interest on the bonds of this series (as defined below) to the persons in whose names such bonds (or their respective predecessor bonds) are registered at the close of business on a special record date for the payment of such Defaulted Interest, which shall be fixed in the following manner (a “Special Record Date”). The Company shall notify the Corporate Trustee referred to below in writing of the amount of Defaulted Interest proposed to be paid on each bond and the date of the proposed payment (which date shall be such as will enable the Corporate Trustee to comply with the next two sentences hereof), and at the same time the Company shall deposit with the Corporate Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Corporate Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the persons entitled to such Defaulted Interest as in this Subsection provided and not to be deemed otherwise part of the trust estate or trust moneys. Thereupon the Corporate Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 or less than 10 days prior to the date of the proposed payment and not less than

10 days after the receipt by the Corporate Trustee of the notice of the proposed payment. The Corporate Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each holder of a bond of this series at such holder’s address as it appears in the bond register not less than 10 days prior to such Special Record Date. The Corporate Trustee may, in its discretion in the name and at the expense of the Company, cause a similar notice to be published at least once in a newspaper approved by the Company in each place of payment of the bonds of this series, but such publication shall not be a condition precedent to the establishment of such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the persons in whose names the bonds of this series (or their respective predecessor bonds) are registered on such Special Record Date and shall no longer be payable pursuant to the following Subsection B.

B.                                    The Company may make payment of any Defaulted Interest on the bonds of this series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such bonds may be listed and upon such notice as may be required by such exchange, if, after notice given by the Company to the Corporate Trustee of the proposed payment pursuant to this Subsection, such payment shall be deemed practicable by the Corporate Trustee.

Subject to the foregoing, each bond of this series delivered under the Mortgage hereinafter mentioned upon transfer of or in exchange for or in lieu of any other bond of this series shall carry all the rights to interest accrued and unpaid, and to accrue, which were carried by such other bond.

This bond is one of an issue of bonds of the Company issuable in series and is one of a series known as its First Mortgage Bonds, 4.20% Series due 2045 (the “bonds of this series”), all bonds of all series issued and to be issued under and equally secured (except in so far as any sinking fund or other fund, established in accordance with the provisions of the Mortgage hereinafter mentioned, may afford additional security for the bonds of any particular series) by a Mortgage and Deed of Trust (together with any indenture supplemental thereto, including the Eighty-fifth Supplemental Indenture, dated as of August 1, 2015, the “Mortgage”), dated as of May 1, 1940, executed by the Company to The Bank of New York Mellon (formerly Irving Trust Company), as Corporate Trustee, and Tina D. Gonzalez (successor to Frederick G. Herbst), as Individual Trustee. Reference is made to the Mortgage for a description of the property mortgaged and pledged, the nature and extent of the security, the rights of the holders of the bonds and of the Trustees in respect thereof, the duties and immunities of the Trustees and the terms and conditions upon which the bonds are and are to be secured and the circumstances under which additional bonds may be issued. With the consent of the Company and to the extent permitted by and as provided in the Mortgage, the rights and obligations of the Company and/or the rights of the holders of the bonds and/or coupons and/or the terms and provisions of the Mortgage may be modified or altered by affirmative vote of the holders of at least 66 2/3% in principal amount of the bonds then outstanding under the Mortgage and, if the rights of one or more, but less than all, series of bonds then outstanding are to be affected, then also by affirmative vote of the holders of at least 66 2/3% in principal amount of the bonds then outstanding of each series of bonds so to be affected (excluding in any case bonds disqualified from voting by reason of the Company’s interest therein as provided in the Mortgage); provided that, without the consent of the holder hereof, no such modification or alteration, among other things, shall impair or affect the right of the holder to receive payment of the principal of and interest on this bond, on or after the respective due dates expressed herein, or permit the creation of any lien equal or prior to the lien of the Mortgage or deprive the holder of a lien on the mortgaged and pledged property.

The principal hereof may be declared or may become due prior to the maturity date hereinbefore named on the conditions, in the manner and at the time set forth in the Mortgage, upon the occurrence of a default as in the Mortgage provided.

This bond is transferable as prescribed in the Mortgage by the registered owner hereof in person, or by his duly authorized attorney, at the office or agency of the Company in the Borough of Manhattan, The City of New York, upon surrender and cancellation of this bond, and thereupon a new fully registered temporary or definitive bond of the same series for a like principal amount will be issued to the transferee in exchange herefor as provided in the Mortgage. The Company and the Trustees may deem and treat the person in whose name this bond is registered as the absolute owner hereof for the purpose of receiving payment and for all other purposes.

In the manner prescribed in the Mortgage, any bonds of this series, upon surrender thereof for cancellation at the office or agency of the Company in the Borough of Manhattan, The City of New York, are exchangeable for a like aggregate principal amount of bonds of the same series of other authorized denominations.

At any time on or after February 15, 2045, the bonds of this series shall be redeemable at the option of the Company, in whole or in part and from time to time, prior to maturity, upon notice as provided in the Mortgage (given not less than 30 days and not more than 90 days prior to the date fixed for redemption), at a redemption price equal to 100% of the principal amount of the bonds then outstanding to be redeemed, plus in each case accrued interest on such principal amount to, but excluding, such date fixed for redemption. At any time prior to February 15, 2045, the bonds of this series shall be redeemable at the option of the Company, in whole or in part and from time to time, upon notice as provided in the Mortgage (given not less than 30 days and not more than 90 days prior to the date fixed for redemption (together with the date fixed for redemption referred to in the preceding sentence, each a “Redemption Date”)), at a redemption price (together with the redemption price referred to in the preceding sentence, each a “Redemption Price”) equal to the greater of (i) 100% of the principal amount of the bonds then outstanding to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on such bonds being redeemed that would be due if such bonds matured on February 15, 2045, computed by discounting such payments, in each case, to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined in the Eighty-fifth Supplemental Indenture mentioned above) plus 20 basis points, plus in either case accrued but unpaid interest on such principal amount to, but excluding, the Redemption Date. On and after any Redemption Date, if sufficient cash shall have been deposited with Corporate Trustee (and/or if the Company has irrevocably directed the Corporate Trustee to apply, from moneys held by it available to be used for the redemption of bonds, sufficient cash) to redeem all of the bonds of this series called for redemption, interest on the bonds of this series, or the portions of them so called for redemption, shall cease to accrue. Reference is made to said Eighty-fifth Supplemental Indenture for the full terms of the redemption provisions applicable to the bonds of this series.

No recourse shall be had for the payment of the principal or any Redemption Price of or interest on this bond against any incorporator or any past, present or future subscriber to the capital stock, stockholder, officer or director of the Company or of any predecessor or successor corporation, as such, either directly or through the Company or any predecessor or successor corporation, under any rule of law, statute or constitution or by the enforcement of any assessment or otherwise, all such liability of incorporators, subscribers, stockholders, officers and directors being released by the holder or owner hereof by the acceptance of this bond and being likewise waived and released by the terms of the Mortgage.

This bond shall not become obligatory until The Bank of New York Mellon (formerly Irving Trust Company), the Corporate Trustee under the Mortgage, or its successor thereunder, shall have signed the form of certificate endorsed hereon.
