          and (ii) the sum of the present values of the remaining scheduled payments of principal and interest (excluding interest accrued to the Redemption Date) on the 2024 Notes, the 2026 Notes, the 2031 Notes, or the 2051 Notes to be redeemed from the

          redemption price equal to 100% of the principal amount of such Senior Notes being redeemed, plus accrued and unpaid interest, if any, on the principal amount of the Senior Notes being redeemed to, but excluding, the Redemption Date (such
          redemption, a “Par Call”). Unless the Company defaults in payment of the Redemption Price, interest will cease to accrue on the Senior Notes or
          portions of the Senior Notes called for redemption on and after the Redemption Date.

      

      

      (a)          Notice of any

          of the Base Indenture at least 10 days but not more than 60 days before the Redemption Date to each Holder of the 2024 Notes, the 2026 Notes, the 2031 Notes, or the 2051 Notes to be redeemed.  If less than all of the Senior Notes then Outstanding

          of the Base Indenture.

      

      

      (b)          Notice of any
          redemption of the Senior Notes in connection with a transaction or an event may, at the Company’s discretion, be given prior to the completion or the occurrence thereof. Any redemption or notice may, at the Company’s discretion, be subject to one
          or more conditions precedent, including, but not limited to, completion or occurrence of a related transaction or event. At the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be
          satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date as so delayed. The Company shall, at its own
          cost and expense, provide, or arrange for written notice of any such delay, non-occurrence or rescission to be given to the holders of the Securities and the Trustee prior to the Redemption Date; provided that, at the Company’s written request provided to the Trustee prior to the
            Redemption Date, notice, prepared by the Company, of any such delay, non-occurrence or rescission shall be given by the Trustee in the name
            and at the expense of the Company.

        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 the 2024 Notes, the 2026 Notes, the 2031 Notes, or the 2051 Notes to be
        redeemed (assuming, for this purpose, that such 2024 Notes, 2026 Notes, 2031 Notes, or 2051 Notes mature on the Par Call Date applicable thereto).

      

      

      “Comparable Treasury Price” means, with
        respect to any Redemption Date for any 2024 Notes, any 2026 Notes, any 2031 Notes, or any 2051 Notes, the average of all Reference Treasury Dealer Quotations obtained by the Company.

      

      

      “Independent Investment Banker” means one
        of the Reference Treasury Dealers appointed by the Company from time to time.

        years prior to the Stated Maturity of the 2024 Notes) in respect of the 2024 Notes, February 15, 2026 (one month prior to the Stated Maturity of the 2026 Notes) in respect of the 2026 Notes, December 15, 2030 (three months prior to the Stated

        Treasury Dealer for that dealer.

      

      

      “Reference Treasury Dealer Quotations”
        means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount)

        corresponding to the remaining term (as measured from the date of redemption) of the series of Senior Notes to be redeemed assuming, for this purpose, that such Senior Notes mature on the Par Call Date applicable thereto (the “Remaining Term”) (if
        no maturity is within three months before or after the Remaining Term for the Senior Notes to be redeemed, yields for the two published maturities most closely corresponding to the Remaining Term will be determined and the Treasury Rate shall be
        interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month), in each case, as calculated by the Company or (2) if such release referred to in clause (1) (or any successor release) is not published during

        (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. The Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date.

      Section 1.08          Change of Control Offer.  (a)  If a Change of Control Triggering Event (as defined below) occurs with respect to any series of Senior Notes, unless the Company
          has exercised its right to redeem such Senior Notes in full, the Company will make an offer to each Holder (the “Change of Control Offer”) of such Senior
          Notes to repurchase any and all of such Holder’s Senior Notes of such series, at a repurchase price in cash equal to 101% of the aggregate principal amount of the Senior Notes of such series repurchased, plus any accrued and unpaid interest
          thereon to, but excluding, the date of repurchase (the “Change of Control Payment”).  Within 30 days following any Change of Control Triggering Event, the
          Company will send a notice to Holders of Senior Notes of such series describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase the Senior Notes on the date specified in the
          notice, which date will be no less than 15 days and no more than 60 days from the date such notice is sent (the “Change of Control Payment Date”), pursuant
          to the procedures required by the Senior Notes and described in such notice.

      

      

      (a)          The Company will comply
          with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other securities laws and
          regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Senior Notes as a result of a Change of Control Triggering Event.  To the extent that the provisions of any securities laws or
          regulations conflict with the Change of Control repurchase provisions of the Senior Notes the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of
          Control repurchase provisions of the Senior Notes by virtue of such conflicts.

      

      

      (b)          The Company will not be
          required to offer to repurchase the Senior Notes upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by
          the Company and the third party repurchases on the applicable date all Senior Notes properly tendered and not withdrawn under its offer; provided that for
          all purposes of the Senior Notes and the Indenture, a failure by such third party to comply with the requirements of such offer and to complete such offer shall be treated as a failure by the Company to comply with its obligations to offer to
          repurchase the Senior Notes unless the Company promptly makes an offer to repurchase the Senior Notes at 101% of the principal amount thereof plus accrued and unpaid interest, if any, thereon, to, but excluding, the date of repurchase, which
          shall be no later than 30 days after the third party’s scheduled Change of Control Payment Date.

      

      

      (c)          On the Change of
          Control Payment Date, the Company will, to the extent lawful:

      

      

      (i)          accept


          or cause a third party to accept for payment all Senior Notes properly tendered pursuant to the Change of Control Offer;

      

      

      (ii)          deposit


          or cause a third party to deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Senior Notes properly tendered; and

      

      

      (i)          deliver


          or cause to be delivered to the Trustee the Senior Notes properly accepted, together with an Officers’ Certificate stating the principal amount of the Senior Notes being purchased.

      

      

      (d)          For the purposes of
          this Section 1.08, the terms below are defined as follows:

      

      

      “Below Investment Grade Rating Event” with
        respect to any series of Senior Notes means such Senior Notes are rated below all Investment Grade Ratings by at least two of the three Rating Agencies on any date from the earlier of (1) the occurrence of a Change of Control and (2) public notice
        of the Company’s intention to effect a Change of Control, in each case until the end of the 60-day period following public notice of the occurrence of the Change of Control; provided, however, that if (a) during such 60-day period, one or more Rating Agencies has publicly announced that it is considering
        the possible downgrade of such series of Senior Notes, and (b) a downgrade by each of the Rating Agencies that has made such an announcement would result in a Below Investment Grade Rating Event, then such 60-day period shall be extended for such
        time as the rating of such series of Senior Notes by any such Rating Agency remains under publicly announced consideration for possible downgrade to a rating below an Investment Grade Rating and a downgrade by such Rating Agency to a rating below
        an Investment Grade Rating could cause a Below Investment Grade Rating Event. Notwithstanding the foregoing, a rating event otherwise arising by virtue of a particular reduction in rating will not be deemed to have occurred in respect of a
        particular Change of Control (and thus will not be deemed a rating event for purposes of the definition of Change of Control Triggering Event) if the Rating Agencies making the reduction in rating to which this definition would otherwise apply do
        not announce or publicly confirm or inform the Trustee in writing at the Company’s or the Trustee’s request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect
        of, the applicable Change of Control (whether or not the applicable Change of Control has occurred at the time of the rating event).

      “Change of Control” means the occurrence of
        any of the following: (1) direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the properties or assets of the
        Company and its subsidiaries taken as a whole to any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than to the Company or one of its subsidiaries; or (2) the consummation of any transaction (including, without
        limitation, any merger or consolidation) the result of which is that any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than the Company or one of its subsidiaries becomes the beneficial owner, directly or indirectly,
        of more than 50% of the then outstanding number of shares of the Company’s voting stock; provided, however, that a transaction will not be deemed to involve a Change of Control if (A) the Company becomes a wholly owned subsidiary of a holding company and (B)(x) the holders of the voting stock of such
        holding company immediately following that transaction are substantially the same as the holders of the Company’s voting stock immediately prior to that transaction or (y) immediately following that transaction no “person” (as that term is used in
        Section 13(d)(3) of the Exchange Act) is the beneficial owner, directly or indirectly, of more than 50% of the voting stock of such holding company. For purposes of this definition, “voting stock” of a person means capital stock of any class or kind the holders of which are ordinarily, in the absence of contingencies, entitled to vote for the election of directors (or persons performing similar
        functions) of such person, even if the right to vote has been suspended by the happening of such a contingency.

      

      

      “Change of Control Triggering Event” means

      If the Company shall at any time act as its own Paying Agent with respect to any series of Securities, it will, on or before each due
        date of the principal of (and premium, if any) or interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal (and premium, if any) or interest
        so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act.

      

      

      Whenever the Company shall have one or more Paying Agents for any series of Securities, it will, on or before each due date of the
        principal of (and premium, if any) or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust Indenture Act to the extent that the Trust Indenture Act
        applies to this Indenture or any Securities, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act.

      

      

      The Company will cause each Paying Agent for any series of Securities other than the Trustee or the Company to execute and deliver to
        the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will (i) comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent
        and (ii) during the continuance of any default by the Company (or any other obligor upon the Securities of that series) in the making of any payment in respect of the Securities of that series, and upon the written request of the Trustee, forthwith
        pay to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Securities of that series.

      

      

      The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose,
        pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or
        such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money.

      

      

      Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of
        (and premium, if any) or interest on any Security of any series and remaining unclaimed for two years after such principal (and premium, if any) or interest has become due and payable shall be paid to the Company on Company Request, or (if then
        held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with
        respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease.

      

      

      Section 1.16          Defeasance.  The provisions of Section 10.06 of the Base Indenture shall apply to the Senior Notes.

      CIGNA CORPORATION, a Delaware corporation (herein called the “Company”), which term includes any successor Person under the Indenture hereinafter referred to, for value received, hereby promises to pay to CEDE & CO., or its registered assigns, the principal sum of [___] Million
        Dollars ($[________]) upon presentation and surrender of this Security on March 15, 2024 and to pay interest thereon accruing from March 3, 2021, or from the most recent date to which interest has been paid or duly provided for, semi-annually in
        arrears on March 15 and September 15 of each year, commencing September 15, 2021, and on the Maturity of this Security (each an “Interest Payment Date”), at
        the rate of 0.613% per annum, until the principal hereof is paid or made available for payment. The amount of interest payable on this Security on any Interest Payment Date shall be computed on the basis of a 360-day year consisting of twelve
        30-day months. The amount of interest payable for any period shorter than a full monthly period shall be computed on the basis of the actual number of calendar days elapsed in such a period. The interest so payable, and punctually paid or duly
        provided for, on any Interest Payment Date will be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date, which shall be the close of business on the
        date that is 15 calendar days prior to the date on which interest is scheduled to be paid, regardless of whether such date is a Business Day (provided
        that if this Security is held by a securities depositary in book-entry form, the Regular Record Date for this security will be the close of business on the Business Day immediately preceding the date on which interest is scheduled to be paid; provided, further, that interest payable on
        the relevant Maturity will be payable to the Persons to whom the principal of this Security is payable).  If an Interest Payment Date is not a Business Day, then such Interest Payment Date shall be the next succeeding Business Day, and no further
        interest will accrue as a result of such delay. Any such interest not punctually paid or duly provided for on any Interest Payment Date shall forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the
        Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to
        Holders of Securities of this series not less than 10 calendar days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of
        this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.

        Trustee or the Paying Agent’s office maintained for that purpose in the Borough of Manhattan, City of New York, in such coin or currency of the United States of America that at the time of payment is legal tender for payment of public and private
        debts; provided, however, that at the option of the Company
        payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register.

      

      

      Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall
        for all purposes have the same effect as if set forth at this place.

        together with the Base Indenture, the “Indenture”), between the Company, as issuer, and U.S. Bank National Association, 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 the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. 
        This Security is one of the series designated on the face hereof, initially limited in aggregate principal amount to $500,000,000, subject to future issuances of additional Securities pursuant to Section 3.01 of the Base Indenture.

      

      

      At any time prior to the Par Call Date (as defined below), the Securities of this series are subject to redemption upon not less than
        10 calendar days’ nor more than 60 calendar days’ notice by mail (or as otherwise delivered in accordance with the applicable procedures of the Depository), in whole or in part, at a redemption price equal to the greater of (i) 100% of the
        principal amount of such Securities to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest (excluding interest accrued to the Redemption Date) on the Securities to be redeemed from the
        Redemption Date to the Par Call Date discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate, plus 7.5 basis points, plus accrued and unpaid interest, if any, on the
        principal amount of the Securities being redeemed to, but excluding, the Redemption Date (the “Make Whole Redemption Price”).

      

      

      At any time on or after the Par Call Date, the Securities of this series are subject to redemption upon not less than 10 calendar
        days’ nor more than 60 calendar days’ notice by mail (or as otherwise delivered in accordance with the applicable procedures of the Depository), in whole or in part, at a redemption price equal to 100% of the principal amount of the Securities
        being redeemed plus accrued and unpaid interest, if any, on the principal amount of the Securities being redeemed to, but excluding, the Redemption Date (together with the Make Whole Redemption Price, the “Redemption Price”).

      

      

      “Comparable Treasury Issue” means the
        United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Securities of this series to be redeemed 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 Securities of this series to be redeemed (assuming, for this purpose, that the Securities of this series
        mature on the Par Call Date).

      

      

      “Comparable Treasury Price” means, with
        respect to any Redemption Date for any Securities of this series, the average of all Reference Treasury Dealer Quotations obtained by the Company.

      

      

      “Independent Investment Banker” means one
        of the Reference Treasury Dealers appointed by the Company from time to time.

      

      

      “Par Call Date” means March 15, 2022 (two
        years prior to the Stated Maturity of the Securities of this series).

      

      

      “Primary Treasury Dealer” means a primary
        U.S. government securities dealer in the United States.

      

      

      “Reference Treasury Dealer” means each of
        Citigroup Global Markets Inc., J.P. Morgan Securities LLC, and Wells Fargo Securities, LLC and their respective successors. If any Reference Treasury Dealer ceases to be a Primary Treasury Dealer, the Company will substitute another Primary
        Treasury Dealer for that dealer.

      

      

      
        A-5

        
          


      

      

      

      “Reference Treasury Dealer Quotations”
        means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Company, 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 that Reference Treasury Dealer at 5:00 p.m. (New York City time) on the third Business Day preceding such Redemption Date.

      

      

      “Treasury Rate” means, with respect to any
        Redemption Date, (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published Data Download Program designated “H.15” or any successor publication which is published
        weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity
        corresponding to the remaining term (as measured from the date of redemption) of this series of Senior Notes assuming, for this purpose, that such Senior Notes mature on the Par Call Date (the “Remaining Term”) (if no maturity is within three
        months before or after the Remaining Term for the Securities of this series, yields for the two published maturities most closely corresponding to the Remaining Term will be determined and the Treasury Rate shall be interpolated or extrapolated
        from such yields on a straight line basis, rounding to the nearest month), in each case, as calculated by the Company or (2) if such release referred to in clause (1) (or any successor release) is not published during the week preceding the
        calculation date or does not contain such yields, the rate per annum 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 such Redemption Date.

      

      

      The Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date.

      

      

      Unless the Company defaults in payment of the Redemption Price, interest will cease to accrue on the Securities of this series called
        for redemption on and after the Redemption Date.  In the event of redemption of this Security in part only, a new Security or Securities of this series for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the
        cancellation hereof.

      

      

      Notice of any redemption of the Securities of this series in connection with a transaction or an event may, at the Company’s
        discretion, be given prior to the completion or the occurrence thereof. Any redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of a related
        transaction or event. At the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all
        such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date as so delayed.

      

      

      If a Change of Control Triggering Event occurs, unless the Company has exercised its right to redeem the Securities of this series in
        full, the Company will make an offer to each Holder (the “Change of Control Offer”) of such Securities to repurchase any and all of such Holder’s Securities
        at a repurchase price in cash equal to 101% of the aggregate principal amount of the Securities of this series repurchased, plus any accrued and unpaid interest thereon to, but excluding, date of repurchase (the “Change of Control Payment”).  Within 30 days following any Change of Control Triggering Event, the Company will send a notice to Holders of Securities of this series describing the
        transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase the Securities of this series on the date specified in the notice, which date will be no less than 15 days and no more than 60 days from
        the date such notice is sent (the “Change of Control Payment Date”), pursuant to the procedures required hereby and described in such notice.

      

      

      The Company will comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the
        repurchase of the Securities of this series as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control repurchase provisions of the Securities of
        this series, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control repurchase provisions of the Securities of this series by virtue of such
        conflicts.

      

      

      
        A-6

        
          


      

      

      

      The Company will not be required to offer to repurchase the Securities of this series upon the occurrence of a Change of Control
        Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and the third party repurchases on the applicable date all Securities of this
        series properly tendered and not withdrawn under its offer; provided that for all purposes of the Securities of this series and the Indenture, a failure by such third party to comply with the requirements of such offer and to complete such offer shall be treated as a failure by the Company to
        comply with its obligations to offer to purchase the Securities of this series unless the Company promptly makes an offer to repurchase the Securities of this series at 101% of the principal amount thereof plus accrued and unpaid interest, if any,
        thereon, to, but excluding, to the date of repurchase, which shall be no later than 30 days after the third party’s scheduled Change of Control Payment Date.

      

      

      On the Change of Control Payment Date, the Company will, to the extent lawful:

      

      

      	

            	•	
              accept or cause a third party to accept for payment all Securities of this series properly tendered pursuant to the Change of Control Offer;

            


      

      

      	

            	•	
              deposit or cause a third party to deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Securities of this series properly
                tendered; and

            


      

      

      	

            	•	
              deliver or cause to be delivered to the Trustee the Securities of this series properly accepted, together with an Officers’ Certificate stating the principal amount
                of the Securities of this series being repurchased.

            


      

      

      “Below Investment Grade Rating Event” means
        the Securities of this series are rated below all Investment Grade Ratings by at least two of the three Rating Agencies on any date from the earlier of (1) the occurrence of a Change of Control and (2) public notice of the Company’s intention to
        effect a Change of Control, in each case until the end of the 60-day period following public notice of the occurrence of the Change of Control; provided, however, that if (i) during such 60-day period one or
        more Rating Agencies has publicly announced that it is considering the possible downgrade of the Securities of this series, and (ii) a downgrade by each of the Rating Agencies that has made such an announcement would result in a Below Investment
        Grade Rating Event, then such 60-day period shall be extended for such time as the rating of the Securities of this series by any such Rating Agency remains under publicly announced consideration for possible downgrade to a rating below an
        Investment Grade Rating and a downgrade by such Rating Agency to a rating below an Investment Grade Rating could cause a Below Investment Grade Rating Event. Notwithstanding the foregoing, a rating event otherwise arising by virtue of a particular
        reduction in rating will not be deemed to have occurred in respect of a particular Change of Control (and thus will not be deemed a rating event for purposes of the definition of Change of Control Triggering Event) if the Rating Agencies making the
        reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Trustee in writing at the Company’s or the Trustee’s request that the reduction was the result, in whole or in part, of any event
        or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control has occurred at the time of the rating event).

      

      

      “Change of Control” means the occurrence of
        any of the following: (1) direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the properties or assets of the
        Company and its subsidiaries taken as a whole to any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than to the Company or one of its subsidiaries; or (2) the consummation of any transaction (including, without
        limitation, any merger or consolidation) the result of which is that any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than the Company or one of its subsidiaries becomes the beneficial owner, directly or indirectly,
        of more than 50% of the then outstanding number of shares of the Company’s voting stock;  provided, however, that a transaction will not be deemed to involve a Change of Control if (A) the Company
        becomes a wholly owned subsidiary of a holding company and (B)(x) the holders of the voting stock of such holding company immediately following that transaction are substantially the same as the holders of the Company’s voting stock immediately
        prior to that transaction or (y) immediately following that transaction no “person” (as that term is used in Section 13(d)(3) of the Exchange Act) is the beneficial owner, directly or indirectly, of more than 50% of the voting stock of such holding
        company. For purposes of this definition, “voting stock” of a person means capital stock of any class or kind the holders of which are ordinarily, in the
        absence of contingencies, entitled to vote for the election of directors (or persons performing similar functions) of such person, even if the right to vote has been suspended by the happening of such a contingency.

      “Change of Control Triggering Event” means
        the occurrence of both a Change of Control and a Below Investment Grade Rating Event.

      

      

       “Fitch” means Fitch Ratings Inc. and any
        successor to its rating agency business.

      

      

      “Investment Grade Rating” means a rating by
        Moody’s equal to or higher than Baa3 (or the equivalent under a successor rating category of Moody’s), a rating by S&P equal to or higher than BBB- (or the equivalent under any successor rating category of S&P), a rating by Fitch equal to
        or higher than BBB- (or the equivalent under any successor rating category of Fitch), and the equivalent investment grade credit rating from any replacement rating agency or rating agencies selected by the Company under the circumstances permitting
        the Company to select a replacement rating agency and in the manner for selecting a replacement rating agency, in each case as set forth in the definition of “Rating Agencies.”

      

      

      “Moody’s” means Moody’s Investors Service,
        Inc. and any successor to its rating agency business.

      

      

      “Rating Agencies” means (1) Moody’s,
        S&P and Fitch; and (2) if any or all of Moody’s, S&P or Fitch ceases to rate the Securities of this series or fails to make a rating of the Securities of this series publicly available for reasons outside of the Company’s control, a
        “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) of the Exchange Act that the Company selects (pursuant to a resolution of the Company’s Board of Directors) as a replacement rating agency for any of
        Moody’s, S&P or Fitch, or all of them, as the case may be, with respect to the Securities of this series, as applicable.

      

      

      “S&P” means Standard & Poor’s
        Ratings Services, a Standard & Poor’s Financial Services LLC business and any successor to its rating agency business.

      

      

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

      

      

      The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and
        obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in aggregate
        principal amount of the Securities at the time Outstanding of each series to be affected.  The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities of each series at the
        time Outstanding, on behalf of the Holders of all 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 Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security 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 Security.

      

      

      No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the
        Company, or the right of the Holder of this Security, which is absolute and unconditional, to pay, or, in the case of the Holder of this Security, to receive payment of, the principal of (and premium, if any) and interest on this Security at the
        times, place and rate, and in the coin or currency, herein prescribed.

      

      

      As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the
        Security Register, upon surrender of this Security for registration of transfer at the Corporate Trust Office of the Trustee or the Paying Agent’s office where the principal of (and premium, if any) and interest on this Security are payable, 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 hereof or such Holder’s attorney duly authorized in writing; and thereupon one or more new
        Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

      

      

      
        A-8

        
          


      

      

      

      The Securities of this series are issuable only in fully registered form, without coupons, in denominations of $2,000 and multiples of
        $1,000 in excess thereof.  As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for other Securities of this series, of a like tenor and aggregate principal amount but of a
        different authorized denomination, as requested by the Holder surrendering the same.

      

      

      No service charge shall be made for any such registration of transfer or exchange, but the Company or the Trustee may require payment
        of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Sections 3.04, 9.06 or 11.07 of the Base Indenture not
        involving any transfer.

      

      

      Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the
        Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the
        contrary.

      

      

      The Indenture provides that the Company, at the Company’s option, (a) will be discharged from any and all obligations in respect of the Securities (except for certain obligations to register the transfer or exchange of Securities, replace stolen, lost or mutilated Securities,
        maintain paying agencies and hold moneys for payment in trust) or (b) need not comply with certain restrictive covenants of the Indenture, in each case if
        the Company deposits, in trust with the Trustee, money, or U.S. Government Obligations which through the payment of interest thereon and principal thereof in accordance with their terms will provide money, in an amount sufficient to pay all the
        principal (including any mandatory sinking fund payments) of (and premium, if any) or interest on the Securities on the dates such payments are due in accordance with the terms of such Securities, and certain other conditions are satisfied.

      

      

      No recourse shall be had for the payment of the principal of or premium, if any, or interest, if any, on this Security, or for any
        claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, or against any past, present or future stockholder, officer, director, employee, or
        agent, as such, of the Company or of any successor Person thereof, whether by virtue of any law, statute or constitutional provision, or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability
        being expressly waived and released as a condition of, and as consideration for, the execution of this Indenture and the issue of the Securities.

      

      

      If and to the extent that any provision of this Security limits, qualifies or conflicts with a provision of the Indenture, such
        provision of the Indenture shall control.

      

      

      All terms used in this Security that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

      CIGNA CORPORATION, a Delaware corporation (herein called the “Company”), which term includes any successor Person under the Indenture hereinafter referred to, for value received, hereby promises to pay to CEDE & CO., or its registered assigns, the principal sum of [___] Million
        Dollars ($[________]) upon presentation and surrender of this Security on March 15, 2026 and to pay interest thereon accruing from March 3, 2021, or from the most recent date to which interest has been paid or duly provided for, semi-annually in
        arrears on March 15 and September 15 of each year, commencing September 15, 2021, and on the Maturity of this Security (each an “Interest Payment Date”), at
        the rate of 1.250% per annum, until the principal hereof is paid or made available for payment. The amount of interest payable on this Security on any Interest Payment Date shall be computed on the basis of a 360-day year consisting of twelve
        30-day months. The amount of interest payable for any period shorter than a full monthly period shall be computed on the basis of the actual number of calendar days elapsed in such a period. The interest so payable, and punctually paid or duly
        provided for, on any Interest Payment Date will be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date, which shall be the close of business on the
        date that is 15 calendar days prior to the date on which interest is scheduled to be paid, regardless of whether such date is a Business Day (provided
        that if this Security is held by a securities depositary in book-entry form, the Regular Record Date for this security will be the close of business on the Business Day immediately preceding the date on which interest is scheduled to be paid; provided, further, that interest payable on
        the relevant Maturity will be payable to the Persons to whom the principal of this Security is payable).  If an Interest Payment Date is not a Business Day, then such Interest Payment Date shall be the next succeeding Business Day, and no further
        interest will accrue as a result of such delay. Any such interest not punctually paid or duly provided for on any Interest Payment Date shall forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the
        Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to
        Holders of Securities of this series not less than 10 calendar days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of
        this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.

        Trustee or the Paying Agent’s office maintained for that purpose in the Borough of Manhattan, City of New York, in such coin or currency of the United States of America that at the time of payment is legal tender for payment of public and private
        debts; provided, however, that at the option of the Company
        payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register.

      

      

      Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall
        for all purposes have the same effect as if set forth at this place.

      

      

      Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual
        signature, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

      “Treasury Rate” means, with respect to any
        Redemption Date, (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published Data Download Program designated “H.15” or any successor publication which is published

        corresponding to the remaining term (as measured from the date of redemption) of this series of Senior Notes assuming, for this purpose, that such Senior Notes mature on the Par Call Date (the “Remaining Term”) (if no maturity is within three
        months before or after the Remaining Term for the Securities of this series, yields for the two published maturities most closely corresponding to the Remaining Term will be determined and the Treasury Rate shall be interpolated or extrapolated
        from such yields on a straight line basis, rounding to the nearest month), in each case, as calculated by the Company or (2) if such release referred to in clause (1) (or any successor release) is not published during the week preceding the
        calculation date or does not contain such yields, the rate per annum 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 such Redemption Date.

      

      

      The Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date.

      

      

      Unless the Company defaults in payment of the Redemption Price, interest will cease to accrue on the Securities of this series called

        cancellation hereof.

      

      

      Notice of any redemption of the Securities of this series in connection with a transaction or an event may, at the Company’s
        discretion, be given prior to the completion or the occurrence thereof. Any redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of a related
        transaction or event. At the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all
        such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date as so delayed.

      

      

      If a Change of Control Triggering Event occurs, unless the Company has exercised its right to redeem the Securities of this series in
        full, the Company will make an offer to each Holder (the “Change of Control Offer”) of such Securities to repurchase any and all of such Holder’s Securities
        at a repurchase price in cash equal to 101% of the aggregate principal amount of the Securities of this series repurchased, plus any accrued and unpaid interest thereon to, but excluding, date of repurchase (the “Change of Control Payment”).  Within 30 days following any Change of Control Triggering Event, the Company will send a notice to Holders of Securities of this series describing the
        transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase the Securities of this series on the date specified in the notice, which date will be no less than 15 days and no more than 60 days from
        the date such notice is sent (the “Change of Control Payment Date”), pursuant to the procedures required hereby and described in such notice.

      

      

      The Company will comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the
        repurchase of the Securities of this series as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control repurchase provisions of the Securities of
        this series, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control repurchase provisions of the Securities of this series by virtue of such
        conflicts.

      

      

      
        B-6

        
          


      

      

      

      The Company will not be required to offer to repurchase the Securities of this series upon the occurrence of a Change of Control
        Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and the third party repurchases on the applicable date all Securities of this
        series properly tendered and not withdrawn under its offer; provided that for all purposes of the Securities of this series and the Indenture, a failure by such third party to comply with the requirements of such offer and to complete such offer shall be treated as a failure by the Company to
        comply with its obligations to offer to purchase the Securities of this series unless the Company promptly makes an offer to repurchase the Securities of this series at 101% of the principal amount thereof plus accrued and unpaid interest, if any,
        thereon, to, but excluding, to the date of repurchase, which shall be no later than 30 days after the third party’s scheduled Change of Control Payment Date.

      

      

      On the Change of Control Payment Date, the Company will, to the extent lawful:

      

      

      	

            	•	
              accept or cause a third party to accept for payment all Securities of this series properly tendered pursuant to the Change of Control Offer;

            


      

      

      	

            	•	
              deposit or cause a third party to deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Securities of this series properly
                tendered; and

            


      

      

      	

            	•	
              deliver or cause to be delivered to the Trustee the Securities of this series properly accepted, together with an Officers’ Certificate stating the principal amount
                of the Securities of this series being repurchased.

            


      

      

      “Below Investment Grade Rating Event” means
        the Securities of this series are rated below all Investment Grade Ratings by at least two of the three Rating Agencies on any date from the earlier of (1) the occurrence of a Change of Control and (2) public notice of the Company’s intention to
        effect a Change of Control, in each case until the end of the 60-day period following public notice of the occurrence of the Change of Control; provided, however, that if (i) during such 60-day period one or
        more Rating Agencies has publicly announced that it is considering the possible downgrade of the Securities of this series, and (ii) a downgrade by each of the Rating Agencies that has made such an announcement would result in a Below Investment
        Grade Rating Event, then such 60-day period shall be extended for such time as the rating of the Securities of this series by any such Rating Agency remains under publicly announced consideration for possible downgrade to a rating below an
        Investment Grade Rating and a downgrade by such Rating Agency to a rating below an Investment Grade Rating could cause a Below Investment Grade Rating Event. Notwithstanding the foregoing, a rating event otherwise arising by virtue of a particular
        reduction in rating will not be deemed to have occurred in respect of a particular Change of Control (and thus will not be deemed a rating event for purposes of the definition of Change of Control Triggering Event) if the Rating Agencies making the
        reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Trustee in writing at the Company’s or the Trustee’s request that the reduction was the result, in whole or in part, of any event
        or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control has occurred at the time of the rating event).

      

      

      “Change of Control” means the occurrence of
        any of the following: (1) direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the properties or assets of the
        Company and its subsidiaries taken as a whole to any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than to the Company or one of its subsidiaries; or (2) the consummation of any transaction (including, without
        limitation, any merger or consolidation) the result of which is that any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than the Company or one of its subsidiaries becomes the beneficial owner, directly or indirectly,
        of more than 50% of the then outstanding number of shares of the Company’s voting stock;  provided, however, that a transaction will not be deemed to involve a Change of Control if (A) the Company
        becomes a wholly owned subsidiary of a holding company and (B)(x) the holders of the voting stock of such holding company immediately following that transaction are substantially the same as the holders of the Company’s voting stock immediately
        prior to that transaction or (y) immediately following that transaction no “person” (as that term is used in Section 13(d)(3) of the Exchange Act) is the beneficial owner, directly or indirectly, of more than 50% of the voting stock of such holding
        company. For purposes of this definition, “voting stock” of a person means capital stock of any class or kind the holders of which are ordinarily, in the
        absence of contingencies, entitled to vote for the election of directors (or persons performing similar functions) of such person, even if the right to vote has been suspended by the happening of such a contingency.

      “Investment Grade Rating” means a rating by
        Moody’s equal to or higher than Baa3 (or the equivalent under a successor rating category of Moody’s), a rating by S&P equal to or higher than BBB- (or the equivalent under any successor rating category of S&P), a rating by Fitch equal to
        or higher than BBB- (or the equivalent under any successor rating category of Fitch), and the equivalent investment grade credit rating from any replacement rating agency or rating agencies selected by the Company under the circumstances permitting
        the Company to select a replacement rating agency and in the manner for selecting a replacement rating agency, in each case as set forth in the definition of “Rating Agencies.”

      

      

      “Moody’s” means Moody’s Investors Service,

        S&P and Fitch; and (2) if any or all of Moody’s, S&P or Fitch ceases to rate the Securities of this series or fails to make a rating of the Securities of this series publicly available for reasons outside of the Company’s control, a
        “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) of the Exchange Act that the Company selects (pursuant to a resolution of the Company’s Board of Directors) as a replacement rating agency for any of
        Moody’s, S&P or Fitch, or all of them, as the case may be, with respect to the Securities of this series, as applicable.

      

      

      “S&P” means Standard & Poor’s

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

      

      

      The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and
        obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in aggregate
        principal amount of the Securities at the time Outstanding of each series to be affected.  The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities of each series at the
        time Outstanding, on behalf of the Holders of all 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 Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security 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 Security.

      

      

      No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the
        Company, or the right of the Holder of this Security, which is absolute and unconditional, to pay, or, in the case of the Holder of this Security, to receive payment of, the principal of (and premium, if any) and interest on this Security at the
        times, place and rate, and in the coin or currency, herein prescribed.

      

      

      
        B-8

        
          


      

      

      

      As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the
        Security Register, upon surrender of this Security for registration of transfer at the Corporate Trust Office of the Trustee or the Paying Agent’s office where the principal of (and premium, if any) and interest on this Security are payable, 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 hereof or such Holder’s attorney duly authorized in writing; and thereupon one or more new
        Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

      

      

      The Securities of this series are issuable only in fully registered form, without coupons, in denominations of $2,000 and multiples of
        $1,000 in excess thereof.  As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for other Securities of this series, of a like tenor and aggregate principal amount but of a
        different authorized denomination, as requested by the Holder surrendering the same.

      

      

      No service charge shall be made for any such registration of transfer or exchange, but the Company or the Trustee may require payment
        of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Sections 3.04, 9.06 or 11.07 of the Base Indenture not
        involving any transfer.

      

      

      Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the
        Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the
        contrary.

      

      

      The Indenture provides that the Company, at the Company’s option, (a) will be discharged from any and all obligations in respect of the Securities (except for certain obligations to register the transfer or exchange of Securities, replace stolen, lost or mutilated Securities,
        maintain paying agencies and hold moneys for payment in trust) or (b) need not comply with certain restrictive covenants of the Indenture, in each case if
        the Company deposits, in trust with the Trustee, money, or U.S. Government Obligations which through the payment of interest thereon and principal thereof in accordance with their terms will provide money, in an amount sufficient to pay all the
        principal (including any mandatory sinking fund payments) of (and premium, if any) or interest on the Securities on the dates such payments are due in accordance with the terms of such Securities, and certain other conditions are satisfied.

      

      

      No recourse shall be had for the payment of the principal of or premium, if any, or interest, if any, on this Security, or for any
        claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, or against any past, present or future stockholder, officer, director, employee, or
        agent, as such, of the Company or of any successor Person thereof, whether by virtue of any law, statute or constitutional provision, or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability
        being expressly waived and released as a condition of, and as consideration for, the execution of this Indenture and the issue of the Securities.

      

      

      If and to the extent that any provision of this Security limits, qualifies or conflicts with a provision of the Indenture, such
        provision of the Indenture shall control.

      

      

      All terms used in this Security that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

        the rate of 2.375% per annum, until the principal hereof is paid or made available for payment. The amount of interest payable on this Security on any Interest Payment Date shall be computed on the basis of a 360-day year consisting of twelve
        30-day months. The amount of interest payable for any period shorter than a full monthly period shall be computed on the basis of the actual number of calendar days elapsed in such a period. The interest so payable, and punctually paid or duly
        provided for, on any Interest Payment Date will be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date, which shall be the close of business on the
        date that is 15 calendar days prior to the date on which interest is scheduled to be paid, regardless of whether such date is a Business Day (provided
        that if this Security is held by a securities depositary in book-entry form, the Regular Record Date for this security will be the close of business on the Business Day immediately preceding the date on which interest is scheduled to be paid; provided, further, that interest payable on
        the relevant Maturity will be payable to the Persons to whom the principal of this Security is payable).  If an Interest Payment Date is not a Business Day, then such Interest Payment Date shall be the next succeeding Business Day, and no further
        interest will accrue as a result of such delay. Any such interest not punctually paid or duly provided for on any Interest Payment Date shall forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the
        Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to
        Holders of Securities of this series not less than 10 calendar days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of
        this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.

      Payment of the principal of (and premium, if any) and interest on this Security will be made at the Corporate Trust Office of the
        Trustee or the Paying Agent’s office maintained for that purpose in the Borough of Manhattan, City of New York, in such coin or currency of the United States of America that at the time of payment is legal tender for payment of public and private
        debts; provided, however, that at the option of the Company
        payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register.

      

      

      Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall
        for all purposes have the same effect as if set forth at this place.

      

      

      Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual
        signature, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

      2.375% Senior Notes due 2031

      

      

      This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of September 17, 2018 (the “Base Indenture”), as supplemented by Supplemental Indenture No. 5, dated as of March 3, 2021 (the “Supplemental Indenture” and,
        together with the Base Indenture, the “Indenture”), between the Company, as issuer, and U.S. Bank National Association, 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 the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. 
        This Security is one of the series designated on the face hereof, initially limited in aggregate principal amount to $1,500,000,000, subject to future issuances of additional Securities pursuant to Section 3.01 of the Base Indenture.

      

      

      At any time prior to the Par Call Date (as defined below), the Securities of this series are subject to redemption upon not less than
        10 calendar days’ nor more than 60 calendar days’ notice by mail (or as otherwise delivered in accordance with the applicable procedures of the Depository), in whole or in part, at a redemption price equal to the greater of (i) 100% of the
        principal amount of such Securities to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest (excluding interest accrued to the Redemption Date) on the Securities to be redeemed from the
        Redemption Date to the Par Call Date discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate, plus 15 basis points, plus accrued and unpaid interest, if any, on the
        principal amount of the Securities being redeemed to, but excluding, the Redemption Date (the “Make Whole Redemption Price”).

      

      

      At any time on or after the Par Call Date, the Securities of this series are subject to redemption upon not less than 10 calendar
        days’ nor more than 60 calendar days’ notice by mail (or as otherwise delivered in accordance with the applicable procedures of the Depository), in whole or in part, at a redemption price equal to 100% of the principal amount of the Securities
        being redeemed plus accrued and unpaid interest, if any, on the principal amount of the Securities being redeemed to, but excluding, the Redemption Date (together with the Make Whole Redemption Price, the “Redemption Price”).

      

      

      “Comparable Treasury Issue” means the
        United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Securities of this series to be redeemed 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 Securities of this series to be redeemed (assuming, for this purpose, that the Securities of this series
        mature on the Par Call Date).

      

      

      “Comparable Treasury Price” means, with
        respect to any Redemption Date for any Securities of this series, the average of all Reference Treasury Dealer Quotations obtained by the Company.

      

      

      “Independent Investment Banker” means one
        of the Reference Treasury Dealers appointed by the Company from time to time.

      

      

      “Par Call Date” means December 15, 2030
        (three months prior to the Stated Maturity of the Securities of this series).

      

      

      “Primary Treasury Dealer” means a primary
        U.S. government securities dealer in the United States.

      

      

      “Reference Treasury Dealer” means each of
        Citigroup Global Markets Inc., J.P. Morgan Securities LLC, and Wells Fargo Securities, LLC and their respective successors. If any Reference Treasury Dealer ceases to be a Primary Treasury Dealer, the Company will substitute another Primary
        Treasury Dealer for that dealer.

      

      

      
        C-5

        
          


      

      

      

      “Reference Treasury Dealer Quotations”
        means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Company, 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 that Reference Treasury Dealer at 5:00 p.m. (New York City time) on the third Business Day preceding such Redemption Date.

      

      

      “Treasury Rate” means, with respect to any
        Redemption Date, (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published Data Download Program designated “H.15” or any successor publication which is published
        weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity
        corresponding to the remaining term (as measured from the date of redemption) of this series of Senior Notes assuming, for this purpose, that such Senior Notes mature on the Par Call Date (the “Remaining Term”) (if no maturity is within three
        months before or after the Remaining Term for the Securities of this series, yields for the two published maturities most closely corresponding to the Remaining Term will be determined and the Treasury Rate shall be interpolated or extrapolated
        from such yields on a straight line basis, rounding to the nearest month), in each case, as calculated by the Company or (2) if such release referred to in clause (1) (or any successor release) is not published during the week preceding the
        calculation date or does not contain such yields, the rate per annum 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 such Redemption Date.

      

      

      The Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date.

      

      

      Unless the Company defaults in payment of the Redemption Price, interest will cease to accrue on the Securities of this series called
        for redemption on and after the Redemption Date.  In the event of redemption of this Security in part only, a new Security or Securities of this series for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the
        cancellation hereof.

      

      

      Notice of any redemption of the Securities of this series in connection with a transaction or an event may, at the Company’s
        discretion, be given prior to the completion or the occurrence thereof. Any redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of a related
        transaction or event. At the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all
        such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date as so delayed.

      

      

      If a Change of Control Triggering Event occurs, unless the Company has exercised its right to redeem the Securities of this series in
        full, the Company will make an offer to each Holder (the “Change of Control Offer”) of such Securities to repurchase any and all of such Holder’s Securities
        at a repurchase price in cash equal to 101% of the aggregate principal amount of the Securities of this series repurchased, plus any accrued and unpaid interest thereon to, but excluding, date of repurchase (the “Change of Control Payment”).  Within 30 days following any Change of Control Triggering Event, the Company will send a notice to Holders of Securities of this series describing the
        transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase the Securities of this series on the date specified in the notice, which date will be no less than 15 days and no more than 60 days from
        the date such notice is sent (the “Change of Control Payment Date”), pursuant to the procedures required hereby and described in such notice.

      

      

      The Company will comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the
        repurchase of the Securities of this series as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control repurchase provisions of the Securities of
        this series, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control repurchase provisions of the Securities of this series by virtue of such
        conflicts.

      

      

      
        C-6

        
          


      

      

      

      The Company will not be required to offer to repurchase the Securities of this series upon the occurrence of a Change of Control
        Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and the third party repurchases on the applicable date all Securities of this
        series properly tendered and not withdrawn under its offer; provided that for all purposes of the Securities of this series and the Indenture, a failure by such third party to comply with the requirements of such offer and to complete such offer shall be treated as a failure by the Company to
        comply with its obligations to offer to purchase the Securities of this series unless the Company promptly makes an offer to repurchase the Securities of this series at 101% of the principal amount thereof plus accrued and unpaid interest, if any,
        thereon, to, but excluding, to the date of repurchase, which shall be no later than 30 days after the third party’s scheduled Change of Control Payment Date.

      

      

      On the Change of Control Payment Date, the Company will, to the extent lawful:

      

      

      	

            	•	
              accept or cause a third party to accept for payment all Securities of this series properly tendered pursuant to the Change of Control Offer;

            


      

      

      	

            	•	
              deposit or cause a third party to deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Securities of this series properly
                tendered; and

            


      

      

      	

            	•	
              deliver or cause to be delivered to the Trustee the Securities of this series properly accepted, together with an Officers’ Certificate stating the principal amount
                of the Securities of this series being repurchased.

            


      

      

      “Below Investment Grade Rating Event” means
        the Securities of this series are rated below all Investment Grade Ratings by at least two of the three Rating Agencies on any date from the earlier of (1) the occurrence of a Change of Control and (2) public notice of the Company’s intention to
        effect a Change of Control, in each case until the end of the 60-day period following public notice of the occurrence of the Change of Control; provided, however, that if (i) during such 60-day period one or
        more Rating Agencies has publicly announced that it is considering the possible downgrade of the Securities of this series, and (ii) a downgrade by each of the Rating Agencies that has made such an announcement would result in a Below Investment
        Grade Rating Event, then such 60-day period shall be extended for such time as the rating of the Securities of this series by any such Rating Agency remains under publicly announced consideration for possible downgrade to a rating below an
        Investment Grade Rating and a downgrade by such Rating Agency to a rating below an Investment Grade Rating could cause a Below Investment Grade Rating Event. Notwithstanding the foregoing, a rating event otherwise arising by virtue of a particular
        reduction in rating will not be deemed to have occurred in respect of a particular Change of Control (and thus will not be deemed a rating event for purposes of the definition of Change of Control Triggering Event) if the Rating Agencies making the
        reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Trustee in writing at the Company’s or the Trustee’s request that the reduction was the result, in whole or in part, of any event
        or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control has occurred at the time of the rating event).

      

      

      “Change of Control” means the occurrence of
        any of the following: (1) direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the properties or assets of the
        Company and its subsidiaries taken as a whole to any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than to the Company or one of its subsidiaries; or (2) the consummation of any transaction (including, without
        limitation, any merger or consolidation) the result of which is that any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than the Company or one of its subsidiaries becomes the beneficial owner, directly or indirectly,
        of more than 50% of the then outstanding number of shares of the Company’s voting stock;  provided, however, that a transaction will not be deemed to involve a Change of Control if (A) the Company
        becomes a wholly owned subsidiary of a holding company and (B)(x) the holders of the voting stock of such holding company immediately following that transaction are substantially the same as the holders of the Company’s voting stock immediately
        prior to that transaction or (y) immediately following that transaction no “person” (as that term is used in Section 13(d)(3) of the Exchange Act) is the beneficial owner, directly or indirectly, of more than 50% of the voting stock of such holding
        company. For purposes of this definition, “voting stock” of a person means capital stock of any class or kind the holders of which are ordinarily, in the
        absence of contingencies, entitled to vote for the election of directors (or persons performing similar functions) of such person, even if the right to vote has been suspended by the happening of such a contingency.

      

      

      “Change of Control Triggering Event” means
        the occurrence of both a Change of Control and a Below Investment Grade Rating Event.

      

      

      
        C-7

        
          


      

       “Fitch” means Fitch Ratings Inc. and any
        successor to its rating agency business.

      

      

      “Investment Grade Rating” means a rating by
        Moody’s equal to or higher than Baa3 (or the equivalent under a successor rating category of Moody’s), a rating by S&P equal to or higher than BBB- (or the equivalent under any successor rating category of S&P), a rating by Fitch equal to
        or higher than BBB- (or the equivalent under any successor rating category of Fitch), and the equivalent investment grade credit rating from any replacement rating agency or rating agencies selected by the Company under the circumstances permitting
        the Company to select a replacement rating agency and in the manner for selecting a replacement rating agency, in each case as set forth in the definition of “Rating Agencies.”

      

      

      “Moody’s” means Moody’s Investors Service,
        Inc. and any successor to its rating agency business.

      

      

      “Rating Agencies” means (1) Moody’s,
        S&P and Fitch; and (2) if any or all of Moody’s, S&P or Fitch ceases to rate the Securities of this series or fails to make a rating of the Securities of this series publicly available for reasons outside of the Company’s control, a
        “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) of the Exchange Act that the Company selects (pursuant to a resolution of the Company’s Board of Directors) as a replacement rating agency for any of
        Moody’s, S&P or Fitch, or all of them, as the case may be, with respect to the Securities of this series, as applicable.

      

      

      “S&P” means Standard & Poor’s
        Ratings Services, a Standard & Poor’s Financial Services LLC business and any successor to its rating agency business.

      

      

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

      

      

      The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and
        obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in aggregate
        principal amount of the Securities at the time Outstanding of each series to be affected.  The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities of each series at the
        time Outstanding, on behalf of the Holders of all 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 Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security 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 Security.

      

      

      No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the
        Company, or the right of the Holder of this Security, which is absolute and unconditional, to pay, or, in the case of the Holder of this Security, to receive payment of, the principal of (and premium, if any) and interest on this Security at the
        times, place and rate, and in the coin or currency, herein prescribed.

      

      

      As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the
        Security Register, upon surrender of this Security for registration of transfer at the Corporate Trust Office of the Trustee or the Paying Agent’s office where the principal of (and premium, if any) and interest on this Security are payable, 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 hereof or such Holder’s attorney duly authorized in writing; and thereupon one or more new
        Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

      
        C-8

        
          


      

      

      

      The Securities of this series are issuable only in fully registered form, without coupons, in denominations of $2,000 and multiples of
        $1,000 in excess thereof.  As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for other Securities of this series, of a like tenor and aggregate principal amount but of a
        different authorized denomination, as requested by the Holder surrendering the same.

      

      

      No service charge shall be made for any such registration of transfer or exchange, but the Company or the Trustee may require payment
        of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Sections 3.04, 9.06 or 11.07 of the Base Indenture not
        involving any transfer.

      

      

      Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the
        Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the
        contrary.

      

      

      The Indenture provides that the Company, at the Company’s option, (a) will be discharged from any and all obligations in respect of the Securities (except for certain obligations to register the transfer or exchange of Securities, replace stolen, lost or mutilated Securities,
        maintain paying agencies and hold moneys for payment in trust) or (b) need not comply with certain restrictive covenants of the Indenture, in each case if

        principal (including any mandatory sinking fund payments) of (and premium, if any) or interest on the Securities on the dates such payments are due in accordance with the terms of such Securities, and certain other conditions are satisfied.

      

      

      No recourse shall be had for the payment of the principal of or premium, if any, or interest, if any, on this Security, or for any
        claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, or against any past, present or future stockholder, officer, director, employee, or

        being expressly waived and released as a condition of, and as consideration for, the execution of this Indenture and the issue of the Securities.

      

      

      If and to the extent that any provision of this Security limits, qualifies or conflicts with a provision of the Indenture, such
        provision of the Indenture shall control.

      

      

      All terms used in this Security that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

      CIGNA CORPORATION, a Delaware corporation (herein called the “Company”), which term includes any successor Person under the Indenture hereinafter referred to, for value received, hereby promises to pay to CEDE & CO., or its registered assigns, the principal sum of [___] Million
        Dollars ($[________]) upon presentation and surrender of this Security on March 15, 2051 and to pay interest thereon accruing from March3, 2021, or from the most recent date to which interest has been paid or duly provided for, semi-annually in
        arrears on March 15 and September 15 of each year, commencing September 15, 2021, and on the Maturity of this Security (each an “Interest Payment Date”), at
        the rate of 3.400% per annum, until the principal hereof is paid or made available for payment. The amount of interest payable on this Security on any Interest Payment Date shall be computed on the basis of a 360-day year consisting of twelve
        30-day months. The amount of interest payable for any period shorter than a full monthly period shall be computed on the basis of the actual number of calendar days elapsed in such a period. The interest so payable, and punctually paid or duly
        provided for, on any Interest Payment Date will be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date, which shall be the close of business on the
        date that is 15 calendar days prior to the date on which interest is scheduled to be paid, regardless of whether such date is a Business Day (provided
        that if this Security is held by a securities depositary in book-entry form, the Regular Record Date for this security will be the close of business on the Business Day immediately preceding the date on which interest is scheduled to be paid; provided, further, that interest payable on
        the relevant Maturity will be payable to the Persons to whom the principal of this Security is payable).  If an Interest Payment Date is not a Business Day, then such Interest Payment Date shall be the next succeeding Business Day, and no further
        interest will accrue as a result of such delay. Any such interest not punctually paid or duly provided for on any Interest Payment Date shall forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the
        Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to
        Holders of Securities of this series not less than 10 calendar days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of
        this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.

        Trustee or the Paying Agent’s office maintained for that purpose in the Borough of Manhattan, City of New York, in such coin or currency of the United States of America that at the time of payment is legal tender for payment of public and private
        debts; provided, however, that at the option of the Company
        payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register.

      

      

      Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall
        for all purposes have the same effect as if set forth at this place.

      CIGNA CORPORATION

      3.400% Senior Notes due 2051

      

      

      This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of September 17, 2018 (the “Base Indenture”), as supplemented by Supplemental Indenture No. 5, dated as of March 3, 2021 (the “Supplemental Indenture” and,
        together with the Base Indenture, the “Indenture”), between the Company, as issuer, and U.S. Bank National Association, 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 the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. 
        This Security is one of the series designated on the face hereof, initially limited in aggregate principal amount to $1,500,000,000, subject to future issuances of additional Securities pursuant to Section 3.01 of the Base Indenture.

      

      

      At any time prior to the Par Call Date (as defined below), the Securities of this series are subject to redemption upon not less than
        10 calendar days’ nor more than 60 calendar days’ notice by mail (or as otherwise delivered in accordance with the applicable procedures of the Depository), in whole or in part, at a redemption price equal to the greater of (i) 100% of the
        principal amount of such Securities to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest (excluding interest accrued to the Redemption Date) on the Securities to be redeemed from the
        Redemption Date to the Par Call Date discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate, plus 20 basis points, plus accrued and unpaid interest, if any, on the
        principal amount of the Securities being redeemed to, but excluding, the Redemption Date (the “Make Whole Redemption Price”).

      

      

      At any time on or after the Par Call Date, the Securities of this series are subject to redemption upon not less than 10 calendar
        days’ nor more than 60 calendar days’ notice by mail (or as otherwise delivered in accordance with the applicable procedures of the Depository), in whole or in part, at a redemption price equal to 100% of the principal amount of the Securities
        being redeemed plus accrued and unpaid interest, if any, on the principal amount of the Securities being redeemed to, but excluding, the Redemption Date (together with the Make Whole Redemption Price, the “Redemption Price”).

      

      

      “Comparable Treasury Issue” means the
        United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Securities of this series to be redeemed 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 Securities of this series to be redeemed (assuming, for this purpose, that the Securities of this series
        mature on the Par Call Date).

      

      

      “Comparable Treasury Price” means, with
        respect to any Redemption Date for any Securities of this series, the average of all Reference Treasury Dealer Quotations obtained by the Company.

      

      

      “Independent Investment Banker” means one
        of the Reference Treasury Dealers appointed by the Company from time to time.

      

      

      “Par Call Date” means September 15, 2050
        (six months prior to the Stated Maturity of the Securities of this series).

      

      

      “Primary Treasury Dealer” means a primary
        U.S. government securities dealer in the United States.

      

      

      “Reference Treasury Dealer” means each of
        Citigroup Global Markets Inc., J.P. Morgan Securities LLC, and Wells Fargo Securities, LLC and their respective successors. If any Reference Treasury Dealer ceases to be a Primary Treasury Dealer, the Company will substitute another Primary
        Treasury Dealer for that dealer.

      

      

      
        D-5

        
          


      

      

      

      “Reference Treasury Dealer Quotations”
        means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Company, 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 that Reference Treasury Dealer at 5:00 p.m. (New York City time) on the third Business Day preceding such Redemption Date.

      

      

      “Treasury Rate” means, with respect to any
        Redemption Date, (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published Data Download Program designated “H.15” or any successor publication which is published
        weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity
        corresponding to the remaining term (as measured from the date of redemption) of this series of Senior Notes assuming, for this purpose, that such Senior Notes mature on the Par Call Date (the “Remaining Term”) (if no maturity is within three
        months before or after the Remaining Term for the Securities of this series, yields for the two published maturities most closely corresponding to the Remaining Term will be determined and the Treasury Rate shall be interpolated or extrapolated
        from such yields on a straight line basis, rounding to the nearest month), in each case, as calculated by the Company or (2) if such release referred to in clause (1) (or any successor release) is not published during the week preceding the
        calculation date or does not contain such yields, the rate per annum 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 such Redemption Date.

      

      

      The Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date.

      

      

      Unless the Company defaults in payment of the Redemption Price, interest will cease to accrue on the Securities of this series called
        for redemption on and after the Redemption Date.  In the event of redemption of this Security in part only, a new Security or Securities of this series for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the
        cancellation hereof.

      

      

      Notice of any redemption of the Securities of this series in connection with a transaction or an event may, at the Company’s
        discretion, be given prior to the completion or the occurrence thereof. Any redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of a related
        transaction or event. At the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all
        such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date as so delayed.

      

      

      If a Change of Control Triggering Event occurs, unless the Company has exercised its right to redeem the Securities of this series in
        full, the Company will make an offer to each Holder (the “Change of Control Offer”) of such Securities to repurchase any and all of such Holder’s Securities
        at a repurchase price in cash equal to 101% of the aggregate principal amount of the Securities of this series repurchased, plus any accrued and unpaid interest thereon to, but excluding, date of repurchase (the “Change of Control Payment”).  Within 30 days following any Change of Control Triggering Event, the Company will send a notice to Holders of Securities of this series describing the
        transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase the Securities of this series on the date specified in the notice, which date will be no less than 15 days and no more than 60 days from
        the date such notice is sent (the “Change of Control Payment Date”), pursuant to the procedures required hereby and described in such notice.

      

      

      The Company will comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the
        repurchase of the Securities of this series as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control repurchase provisions of the Securities of
        this series, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control repurchase provisions of the Securities of this series by virtue of such
        conflicts.

      

      

      The Company will not be required to offer to repurchase the Securities of this series upon the occurrence of a Change of Control
        Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and the third party repurchases on the applicable date all Securities of this
        series properly tendered and not withdrawn under its offer; provided that for all purposes of the Securities of this series and the Indenture, a failure by such third party to comply with the requirements of such offer and to complete such offer shall be treated as a failure by the Company to
        comply with its obligations to offer to purchase the Securities of this series unless the Company promptly makes an offer to repurchase the Securities of this series at 101% of the principal amount thereof plus accrued and unpaid interest, if any,
        thereon, to, but excluding, to the date of repurchase, which shall be no later than 30 days after the third party’s scheduled Change of Control Payment Date.

      

      

      On the Change of Control Payment Date, the Company will, to the extent lawful:

      

      

      	

            	•	
              accept or cause a third party to accept for payment all Securities of this series properly tendered pursuant to the Change of Control Offer;

            


      

      

      	

            	•	
              deposit or cause a third party to deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Securities of this series properly
                tendered; and

            


      

      

      	

            	•	
              deliver or cause to be delivered to the Trustee the Securities of this series properly accepted, together with an Officers’ Certificate stating the principal amount
                of the Securities of this series being repurchased.

            


      

      

      
        D-6

        
          


      

      “Below Investment Grade Rating Event” means
        the Securities of this series are rated below all Investment Grade Ratings by at least two of the three Rating Agencies on any date from the earlier of (1) the occurrence of a Change of Control and (2) public notice of the Company’s intention to
        effect a Change of Control, in each case until the end of the 60-day period following public notice of the occurrence of the Change of Control; provided, however, that if (i) during such 60-day period one or
        more Rating Agencies has publicly announced that it is considering the possible downgrade of the Securities of this series, and (ii) a downgrade by each of the Rating Agencies that has made such an announcement would result in a Below Investment
        Grade Rating Event, then such 60-day period shall be extended for such time as the rating of the Securities of this series by any such Rating Agency remains under publicly announced consideration for possible downgrade to a rating below an
        Investment Grade Rating and a downgrade by such Rating Agency to a rating below an Investment Grade Rating could cause a Below Investment Grade Rating Event. Notwithstanding the foregoing, a rating event otherwise arising by virtue of a particular
        reduction in rating will not be deemed to have occurred in respect of a particular Change of Control (and thus will not be deemed a rating event for purposes of the definition of Change of Control Triggering Event) if the Rating Agencies making the
        reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Trustee in writing at the Company’s or the Trustee’s request that the reduction was the result, in whole or in part, of any event
        or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control has occurred at the time of the rating event).

      

      

      “Change of Control” means the occurrence of
        any of the following: (1) direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the properties or assets of the
        Company and its subsidiaries taken as a whole to any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than to the Company or one of its subsidiaries; or (2) the consummation of any transaction (including, without
        limitation, any merger or consolidation) the result of which is that any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than the Company or one of its subsidiaries becomes the beneficial owner, directly or indirectly,
        of more than 50% of the then outstanding number of shares of the Company’s voting stock;  provided, however, that a transaction will not be deemed to involve a Change of Control if (A) the Company
        becomes a wholly owned subsidiary of a holding company and (B)(x) the holders of the voting stock of such holding company immediately following that transaction are substantially the same as the holders of the Company’s voting stock immediately
        prior to that transaction or (y) immediately following that transaction no “person” (as that term is used in Section 13(d)(3) of the Exchange Act) is the beneficial owner, directly or indirectly, of more than 50% of the voting stock of such holding
        company. For purposes of this definition, “voting stock” of a person means capital stock of any class or kind the holders of which are ordinarily, in the
        absence of contingencies, entitled to vote for the election of directors (or persons performing similar functions) of such person, even if the right to vote has been suspended by the happening of such a contingency.

      

      

      
        D-7

        
          


      

      

      

      “Change of Control Triggering Event” means

        contrary.

        maintain paying agencies and hold moneys for payment in trust) or (b) need not comply with certain restrictive covenants of the Indenture, in each case if
        the Company deposits, in trust with the Trustee, money, or U.S. Government Obligations which through the payment of interest thereon and principal thereof in accordance with their terms will provide money, in an amount sufficient to pay all the
        principal (including any mandatory sinking fund payments) of (and premium, if any) or interest on the Securities on the dates such payments are due in accordance with the terms of such Securities, and certain other conditions are satisfied.

        claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, or against any past, present or future stockholder, officer, director, employee, or
        agent, as such, of the Company or of any successor Person thereof, whether by virtue of any law, statute or constitutional provision, or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability
        being expressly waived and released as a condition of, and as consideration for, the execution of this Indenture and the issue of the Securities.

      

      

      If and to the extent that any provision of this Security limits, qualifies or conflicts with a provision of the Indenture, such
        provision of the Indenture shall control.

      

      

      All terms used in this Security that are defined in the Indenture shall have the meanings assigned to them in the Indenture.
