        defined below), notice of which will be given to Holders of [Notes][Debentures] not less than 10 days prior to such Special Record Date, or (2) be paid at any time in any other lawful manner not inconsistent with the requirements of any securities
        exchange on which the [Notes][Debentures] may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture. Payment of the principal of and interest on this [Note][Debenture] will be made at the
        Corporate Trust Office of the Trustee in the Borough of Manhattan, The City of New York, or at the office or agency of the Trustee maintained for that purpose in the Borough of Manhattan, The City of New York, or at any other office or agency
        designated by the Company for such purpose, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided that, at the
        option of the Company, payment of interest due on any Interest Payment Date may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register or by wire transfer of immediately available
        funds if appropriate wire transfer instructions have been received in writing by the Trustee not less than 15 days prior to the applicable Interest Payment Date.

      This [Note][Debenture] is one of a duly authorized issue of securities (herein called the “Securities”) of the Company, issued and to be issued pursuant to the Indenture (as
        defined below). This [Note][Debenture] is one of a series designated by the Company as its [  ]% [Senior Notes][Debentures] due 20[  ] (the “[Notes][Debentures]”), limited in initial aggregate principal
        amount to $[  ]. The Indenture does not limit the aggregate principal amount of the Securities.

       

      The Company issued this [Note][Debenture] pursuant to an Indenture, dated as of August 8, 2019 (herein called the “Indenture” which term, for the purpose of this
        [Note][Debenture], shall include the Officer’s Certificate dated [   ], 2019, delivered pursuant to Sections 201 and 301 of the Indenture), between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations
        of rights, duties and immunities thereunder of the Company, the Trustee and Holders of the [Notes][Debentures] and of the terms upon which the [Notes][Debentures] are, and are to be, authenticated and delivered.

       

      The [Notes][Debentures] are issuable in denominations of $2,000 and any amount in excess thereof which is an integral multiple of $1,000. As provided in the Indenture and subject to certain limitations therein set
        forth, the [Notes][Debentures] are exchangeable for a like aggregate principal amount of [Notes][Debentures] of like tenor of any authorized denomination, as requested by the Holder surrendering the same, upon surrender of the [Note][Debenture] or
        [Notes][Debentures] to be exchanged at any office or agency described below where [Notes][Debentures] may be presented for registration of transfer.

       

      The Company may, from time to time, without notice to or the consent of the Holders of the [Notes][Debentures], reopen the [Notes][Debentures] and issue additional [Notes][Debentures].

       

      The [Notes][Debentures] are redeemable, in whole at any time or in part from time to time prior to [final maturity] [[  ] (the “Par Call Date”)]6, at the option of the Company at a Redemption Price equal to the greater of (i) 100% of the principal amount of the [Notes][Debentures] to be redeemed and (ii) as determined by the Quotation
        Agent, the sum of the present values of the remaining scheduled payments of principal and interest on the [Notes][Debentures] to be redeemed through the [final maturity][Par Call Date] (not including any portion of such payments of interest accrued
        to, but not including, the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year comprised of twelve 30-day months) at the Treasury Rate (as defined herein) [plus [  ] basis points]7 plus, in each case, accrued and unpaid interest on the principal amount of the [Notes][Debentures] being redeemed to, but not including, the Redemption Date. [On and
        after the Par Call Date, the [Notes][Debentures] are redeemable, in whole at any time or in part from time to time, at the option of the Company at a Redemption Price equal to 100% of the principal amount of the [Notes][Debentures] to be redeemed,
        plus accrued and unpaid interest on the principal amount of the [Notes][Debentures] being redeemed to, but not including, the Redemption Date.] Notwithstanding the foregoing, installments of interest whose Stated Maturity is on or prior to the
        relevant Redemption Date shall be payable to the Holders of the [Notes][Debentures], or one or more Predecessor Securities, of record at the close of business on the relevant Regular Record Dates according to their terms and the provisions of the
        Indenture.

                    corresponding to the Comparable Treasury Issue; provided that if no maturity is within three months before or after the remaining term of the [Notes][Debentures] to be redeemed [(assuming, for this purpose, that the [Notes][Debentures]
                    mature on the Par Call Date)], yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from those yields on a
                    straight-line basis rounding to the nearest month; or

                


        

      

       

      
        
          	

                	•	
                  if that release, or any successor release, is not published during the week preceding the calculation date or does not contain such yields, the rate per year equal to the semi-annual equivalent yield to maturity of the Comparable
                    Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that Redemption Date.

                


        

      

       

      The Treasury Rate will be calculated at 5:00 p.m. (New York City time) on the third Business Day preceding the Redemption Date by the Quotation Agent.

       

      “Comparable Treasury Issue” means, with respect to any Redemption Date, the United States Treasury security selected by the Quotation Agent 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 of the [Notes][Debentures] [(assuming, for this purpose, that the [Notes][Debentures]
        mature on the Par Call Date)].

       

      
        7

        
          


      

      “Comparable Treasury Price” means, with respect to any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the
        highest and lowest Reference Treasury Dealer Quotations, or (2) if the Quotation Agent obtains fewer than three Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations, such average in any case to be
        determined by the Quotation Agent, or (3) if only one Reference Treasury Dealer Quotation is received, such Reference Treasury Dealer Quotation.

       

      “Quotation Agent” means, with respect to any Redemption Date, the Reference Treasury Dealer appointed by the Company.

       

      “Reference Treasury Dealer” means, with respect to any Redemption Date, each of (1) BofA Securities, Inc. and Citigroup Global Markets Inc. (or their respective affiliates that
        are primary U.S. Government securities dealers) and their respective successors; provided, however, that if any of them shall cease to be a primary U.S. Government securities dealer in the United States of America (a “Primary Treasury Dealer”), the Company shall substitute for it another Primary Treasury Dealer; and (2) any other Primary Treasury Dealer or Dealers selected by the Company.

       

      “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 in The City of New York preceding such Redemption Date.

       

      Notice of any redemption will be sent at least 10 days but not more than 60 days before the Redemption Date to each Holder of the [Notes][Debentures] to be redeemed, all as more fully provided in the Indenture. Unless
        the Company defaults in payment of the Redemption Price (or any accrued and unpaid interest on the [Notes][Debentures] or portions thereof to be redeemed), on and after the Redemption Date interest will cease to accrue on the [Notes][Debentures] or
        portions thereof called for redemption. If less than all of the [Notes][Debentures] are to be redeemed, the [Notes][Debentures] (or portions thereof) to be redeemed shall be selected, in the case of Global Notes, in accordance with the policies and
        procedures of the depository or, in the case of Definitive Notes, by the Trustee by such method as the Trustee shall deem fair and appropriate, all as more fully provided in the Indenture.

       

      All notices of redemption shall state the Redemption Date, the Redemption Price (or, if not then ascertainable, the manner of calculation thereof), if fewer than all the Outstanding [Notes][Debentures] are to be
        redeemed, the identification (and, in the case of partial redemption, the principal amounts) of the particular [Notes][Debentures] to be redeemed, that on the Redemption Date the Redemption Price will become due and payable upon each
        [Note][Debenture], or portion thereof, to be redeemed, together with accrued and unpaid interest thereon, that interest on each [Note][Debenture], or portion thereof, called for redemption will cease to accrue on the Redemption Date and the place
        or places where [Notes][Debentures] may be surrendered for redemption.

       

      
        8

        
          


      

      In the event of redemption of this [Note][Debenture] in part only, a new [Note][Debenture] or [Notes][Debentures] of like tenor in an aggregate principal amount equal to and in exchange for the unredeemed portion of
        the principal amount hereof will be issued in authorized denominations in the name of the Holder hereof upon surrender hereof.

       

      For all purposes of this [Note][Debenture] and the Indenture, unless the context otherwise requires, all provisions relating to the redemption by the Company of this [Note][Debenture] shall relate, in the case that
        this [Note][Debenture] is redeemed, or to be redeemed, by the Company only in part, to that portion of the principal amount of this [Note][Debenture] that has been, or is to be, redeemed.

       

      If an Event of Default with respect to [Notes][Debentures] shall occur and be continuing, the principal of and accrued interest on the [Notes][Debentures] may be declared due and payable in the manner and with the
        effect provided in the Indenture.

       

      [Conditional Right to Shorten Maturity.

       

      At the election of the Company, the Debentures may have their maturity shortened upon the occurrence of a Tax Event, to the extent required, in the opinion of a nationally recognized independent tax counsel, so that,
        after the shortening of the maturity, interest paid on the Debentures will be deductible for federal income tax purposes.

       

      In the event that the Company elects to exercise its right to shorten the maturity of the Debentures due to the occurrence of a Tax Event, the Company shall mail a notice of shortened maturity to each Holder of record
        of the Debentures by first-class mail, or otherwise deliver in accordance with the applicable procedures of the Depository, not more than 60 days after the occurrence of such Tax Event, stating the new maturity date of the Debentures.  Such notice
        would be effective upon mailing.

       

      “Tax Event” means that the Company shall have received an opinion of a nationally recognized independent tax counsel to the effect that on or after the date of the Indenture, as a result of (a) any amendment to,
        clarification of, or change (including any announced prospective change) in laws, or any regulations thereunder, of the United States, (b) any judicial decision, official administrative pronouncement, ruling, regulatory procedure, notice or
        announcement, including any notice or announcement of intent to adopt such procedures or regulations (an “Administrative Action”), or (c) any amendment to, clarification of, or change in the official position or the interpretation of an
        Administrative Action or judicial decision that differs from the theretofore generally accepted position, in each case, on or after the date of the Indenture, such change in tax law creates a more than insubstantial risk that interest paid by the
        Company on the Debentures is not, or will not be, deductible, in whole or in part, by the Company for purposes of federal income tax.]8

       

      
        

         

          

        8 The series of Securities which shall include the bracketed language are the: (i) 7.250% Debentures due 2096 and (ii) 7.500%
          Debentures due 2096.

        [Redemption Right.

         

        On September 15, 2026, or if such date is not a Business Day, then the next succeeding Business Day (the ‘‘2026 Redemption Date’’), each Holder of the Debentures shall have the right (the ‘‘Redemption Right’’) to
          require the Company to redeem, in whole or in part, such Holder’s Debenture at a redemption price equal to 100% of the aggregate principal amount thereof plus accrued and unpaid interest thereon to, but not including, the 2026 Redemption Date.

         

        On or prior to July 1, 2026, the Company shall mail a notice to each Holder stating that (a) in order for a Holder to exercise the Redemption Right, the Holder must surrender the Debentures in respect of which the
          Redemption Right is being exercised, or transfer such Debentures by book-entry form, to the Trustee during the period from July 15, 2026 and prior to 5:00 p.m. (New York City time) on August 14, 2026 (or if such date is not a Business Day, then
          the next succeeding Business Day), (b) any election on the part of a Holder to exercise the Redemption Right effected in accordance with the foregoing shall be irrevocable on the part of the Holder and may not be withdrawn, (c) Holders whose
          Debentures are being redeemed only in part will be issued new Debentures equal in principal amount to the unredeemed portion of the Debentures surrendered, which unredeemed portion must be equal to $1,000 in principal amount or an integral
          multiple of $1,000 thereof and (d) unless the Company defaults in the payment of principal and accrued interest on the Debentures to be redeemed on the 2026 Redemption Date, interest on such Debentures will cease to accrue on the Redemption
          Date.]9

         

        If an Event of Default with respect to [Notes][Debentures] shall occur and be continuing, the principal of and accrued interest on the [Notes][Debentures] may be declared due and payable in the manner and with the
          effect provided in the Indenture.

         

        The Indenture permits, in certain circumstances therein specified, the amendment thereof without the consent of the Holders of the Securities. The Indenture also permits, with certain exceptions as therein provided,
          the amendment thereof and the modification of the rights and obligations under the Indenture of the Company and the rights of 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 (i) the Holders of not less than a majority in principal amount of the Outstanding Securities of all series voting as a single class or (ii) if fewer than all of the series of the Outstanding Securities are affected by such
          addition, change, elimination, or modification, the Holders of not less than a majority in principal amount of the Outstanding Securities of all series so affected voting as a single class (including, for the avoidance of doubt, consents obtained
          in connection with a purchase of, or tender offer or exchange for, such debt securities). The Indenture also contains provisions permitting the Holders of not less than a majority in aggregate principal amount of the Outstanding Securities of any
          series, on behalf of the Holders of all Outstanding Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or
          waiver by the Holder of this [Note][Debenture] shall be conclusive and binding upon such Holder and upon all future Holders of this [Note][Debenture] and of any [Note][Debenture] issued upon the registration of transfer hereof or in exchange
          herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this [Note][Debenture].

        No reference herein to the Indenture and no provision of this [Note][Debenture], subject to the provisions for satisfaction and discharge in Article Four of the Indenture, shall alter or impair the obligation of the
          Company, which is absolute and unconditional, to pay the principal of and interest on this [Note][Debenture] at the times, place and rate, and in the coin or currency, herein prescribed.

         

        The Company shall be permitted, by irrevocably depositing cash or U.S. Government Obligations, in amounts and maturities sufficient to pay and discharge at the Stated Maturity or Redemption Date, as the case may be,
          the entire indebtedness on all Outstanding [Notes][Debentures] that have become due and payable or will become due and payable within one year (or are scheduled for redemption within one year), with the Trustee in trust, solely for the benefit of
          the Holders of all Outstanding [Notes][Debentures], to defease the Indenture with respect to such [Notes][Debentures] (subject to specified exceptions), and upon such deposit and satisfaction of the other conditions set forth in the Indenture,
          the Company shall be deemed to have paid and discharged its entire indebtedness on the [Notes][Debentures].

         

        The Company shall also be permitted to discharge, at any time, its obligations in respect of the [Notes][Debentures] (other than certain limited obligations, such as the obligation to transfer and exchange the
          [Notes][Debentures]) by (1)(a) delivering all of the outstanding [Notes][Debentures] to the Trustee to be cancelled or (b) depositing with the Trustee in trust funds or non-callable United States government or government-guaranteed obligations
          sufficient, without investment, to pay all remaining principal and interest on the [Notes][Debentures] and (2) complying with certain other provisions of the Indenture[, including delivering to the Trustee an opinion of counsel from a nationally
          recognized counsel or an IRS ruling stating that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the date of the Indenture, there has been a change in the applicable federal
          income tax law, in the case of either (A) or (B) to the effect that the Holders of the [Notes][Debentures] will not recognize income, gain or loss for federal income tax purposes as a result of such discharge and will be subject to federal income
          tax on the same amount, in the same manner and at the same times as would be the case if such deposit and discharge were not to occur.]10

         

        [The Company shall also be permitted to omit to comply with the restrictive covenants described in Sections 1007 and 801 of the Indenture, with respect to the Notes, and the omission shall not be an Event of Default,
          pursuant to the Company’s right to covenant defeasance. In order to exercise the Company’s right to covenant defeasance, the Company will be required to deposit with the Trustee, in trust funds or non-callable United States government or
          government-guaranteed obligations, funds sufficient, without investment, to pay all remaining principal and interest on the Notes. To effect a covenant defeasance with respect to the Notes, the Company shall be required to deliver to the Trustee
          an opinion of counsel to the effect that the holders of the Notes will not recognize gain or loss for federal income tax purposes as a result of the deposit and the covenant defeasance and will be subject to federal income tax on the same amount,
          in the same manner and at the same times as would be the case if such deposit and covenant defeasance were not to occur.]11

          duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder thereof or his attorney duly authorized in writing, and thereupon one or more new
          [Notes][Debentures] of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

         

        No service charge shall be made by the Company, the Trustee or the Security Registrar for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or
          other governmental charge payable in connection therewith (other than exchanges pursuant to Sections 304, 305, 906 or 1107 of the Indenture not involving any transfer).
