-11-

(c) The rate of interest on each 5-Year Floating Rate Note shall be a floating rate, reset quarterly, equal to LIBOR determined as described herein plus 0.89% per annum, accruing from the date of original issuance or from the most recent date to which interest has been paid or duly provided for, payable semi-annually in arrears on January 15, April 15, July 15 and October 15 of each year, commencing on October 15, 2018 and on the Maturity of such series.

(d) The amount of interest payable in respect of any Floating Rate Note, and punctually paid or duly provided for, on any interest payment date specified in Section 2.05(a), (b) and (c) (each, a "Floating Rate Interest Payment Date") will be paid to the Person in whose name such Floating Rate Note (or one or more Predecessor Securities) is registered on the Regular Record Date, provided that if any of the Floating Rate Notes are held by a securities depositary in book-entry form, the Regular Record Date for such Floating Rate Notes 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 at the relevant Maturity will be payable to the Persons to whom the principal of such Fixed Rate Notes is payable.

(e) If a Floating Rate Interest Payment Date (other than any Maturity) is not a Business Day, then such Floating Rate Interest Payment Date shall be the next succeeding Business Day, unless the next succeeding Business Day is in the next succeeding calendar month, in which case such Floating Rate Interest Payment Date shall be the immediately preceding Business Day. If the relevant Maturity of any Floating Rate Note falls on a day that is not a Business Day, the payment of principal and interest, if any, otherwise payable on such date will be postponed to the next succeeding Business Day, and no interest on such payment will accrue from and after such Maturity.

(f) The Floating Rate Notes will bear interest for each Interest Period at a rate determined by U.S. Bank National Association, acting as calculation agent, or any successor thereto, including a successor appointed pursuant to 2.05(i) (the "Calculation Agent").

(g) The interest rate for each Interest Period will be reset for the 18-Month Floating Rate Notes and the 3-Year Floating Rate Notes on March 17, June 17, September 17 and December 17 of each year and for the 5-Year Floating Rate Notes on January 15, April 15, July 15 and October 15 of each year (each such date, an "Interest Reset Date"), and will be set for the initial Interest Period on the date of original issuance on the Floating Rate Notes. If any Interest Reset Date would otherwise be a day that is not a Business Day, such Interest Reset Date shall be the next succeeding Business Day, unless the next succeeding Business Day is in the next succeeding calendar month, in which case such Interest Reset Date shall be the immediately preceding Business Day. The initial Interest Period for the Floating Rate Notes will be the period from and including September 17, 2018 to, but excluding, the first Interest Reset Date. Thereafter, an "Interest Period" shall mean the period from and including an Interest Reset Date to, but excluding, the next succeeding Interest Reset Date and, in the case of the last such period, from and including the Interest Reset Date immediately preceding Maturity, but excluding, such Maturity.

-12-

(h) The interest determination date for the initial Interest Period will be the date that is the second London Business Day preceding the date of original issuance of the Floating Rate Notes and for any other Interest Period will be the second London Business Day preceding the relevant Interest Reset Date (the "Interest Determination Date"). A "London Business Day" is a day on which dealings in deposits in U.S. dollars are transacted in the London interbank market. Promptly upon determination, the Calculation Agent will inform the Company of the interest rate for the next Interest Period.

(i) Absent manifest error, the determination of the interest rate by the Calculation Agent shall be conclusive and binding on the Holders of the Floating Rate Notes, the Trustee and the Company. So long as LIBOR is required to be determined with respect to the Floating Rate Notes, there will at all times be a Calculation Agent. In the event that any then acting Calculation Agent shall be unable or unwilling to act, or that such Calculation Agent shall fail to duly establish LIBOR for any Interest Period, or that the Company proposes to remove such Calculation Agent, the Company shall appoint another Person which is a bank, trust company, investment banking firm or other financial institution to act as the Calculation Agent.

(j) On any Interest Determination Date, LIBOR will be equal to the offered rate for deposits in U.S. dollars having an index maturity of three months as such rate appears on "Reuters Page LIBOR01" at approximately 11:00 a.m., London time, on such Interest Determination Date. If on an Interest Determination Date, such rate does not appear on the "Reuters Page LIBOR01" at approximately 11:00 a.m., London time, or if "Reuters Page LIBOR01" is not available at such time, the Calculation Agent will obtain such rate from Bloomberg L.P.'s page "BBAM."

(k) Subject to Section 2.05(l), if no offered rate appears on "Reuters Page LIBOR01" or Bloomberg L.P.'s page "BBAM" on an Interest Determination Date at approximately 11:00 a.m., London time, then the Company will select four major banks in the London interbank market and shall request each of their principal London offices to provide to the Calculation Agent a quotation of the rate at which three-month deposits in U.S. dollars in amounts of at least $1 million are offered by it to prime banks in the London interbank market, on that date and at that time, that is representative of single transactions at that time. If at least two quotations are provided, LIBOR will be the arithmetic average of the quotations provided. Otherwise, the Company will select three major banks in New York City and shall request each of them to provide to the Calculation Agent a quotation of the rate offered by them at approximately 11:00 a.m., New York City time, on the Interest Determination Date for loans in U.S. dollars to leading European banks having an index maturity of three months for the applicable Interest Period in an amount of at least $1 million that is representative of single transactions at that time. If three quotations are provided, LIBOR will be the arithmetic average of the quotations provided. Otherwise, the rate of LIBOR for the next Interest Period will be set equal to the rate of LIBOR for the then current Interest Period.

-13-

(l) Notwithstanding Section 2.05(k), if the Company, in its sole discretion, determines that LIBOR has been permanently discontinued and the Company has notified the Calculation Agent of such determination (a "LIBOR Event"), the Calculation Agent will use, as directed by the Company, as a substitute for LIBOR (the "Alternative Rate") for each future floating rate Interest Determination Date, the alternative reference rate selected by the central bank, reserve bank, monetary authority or any similar institution (including any committee or working group thereof) that is consistent with market practice regarding a substitute for LIBOR. As part of such substitution, the Calculation Agent will, as directed by the Company, make such adjustments to the Alternative Rate or the spread thereon, as well as the business day convention, interest determination dates and related provisions and definitions ("Adjustments"), in each case that are consistent with market practice for the use of such Alternative Rate. Notwithstanding the foregoing, if the Company determines that there is no alternative reference rate selected by the central bank, reserve bank, monetary authority or any similar institution (including any committee or working group thereof) that is consistent with market practice regarding a substitute for LIBOR, the Company may, in its sole discretion, appoint an independent financial advisor ("IFA") to determine an appropriate Alternative Rate and any Adjustments, and the decision of the IFA will be conclusive and binding on the Company, the Calculation Agent, the Trustee and the Holders of Floating Rate Notes. If a LIBOR Event has occurred, but for any reason an Alternative Rate has not been determined or there is no such market practice for the use of such Alternative Rate (and, in each case, an IFA has not determined an appropriate Alternative Rate and Adjustments), the rate of LIBOR for the next Interest Period will be set equal to the rate of LIBOR for the then current Interest Period (for purposes hereof, this Section 2.05(l) will be referred to as the "LIBOR Alternative Rate Provision").

(m) The amount of interest for each day that the Floating Rate Notes of any series are Outstanding (the "Daily Interest Amount") will be calculated by dividing the floating interest rate in effect for such day for such series by 360 and multiplying the result by the principal amount of the Floating Rate Notes of such series (known as the "Actual/360" day count). The amount of interest to be paid on the Floating Rate Notes for any Interest Period will be calculated by adding the Daily Interest Amounts for each day in such Interest Period.

(n) Notwithstanding the foregoing or anything to the contrary provided herein, the interest rate on the Floating Rate Notes will be limited to the maximum rate permitted by New York law, as the same may be modified by United States law of general application.

(o) All percentages resulting from any calculation of any interest rate for the Floating Rate Notes will be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upward (e.g., 9.876545% (or .09876545) would be rounded to 9.87655% (or .0987655)), and all U.S. dollar amounts will be rounded to the nearest cent, with one-half cent being rounded upward.

(p) Upon prior written request from any Holder of the Floating Rate Notes, the Calculation Agent will provide the interest rate in effect on the Floating Rate Notes for the current Interest Period and, if it has been determined, the interest rate to be in effect for the next Interest Period.

(i)

The transfer and exchange of Global Notes or beneficial interests therein shall be effected through the Depository, in accordance with this Supplemental Indenture (including applicable restrictions on transfer set forth herein, if any) and the procedures of the Depository therefor.

-17-

(ii)

If the proposed transfer is a transfer of a beneficial interest in one Global Note to a beneficial interest in another Global Note, the Security Registrar shall reflect on its books and records the date and an increase in the principal amount of the Global Note to which such interest is being transferred in an amount equal to the principal amount of the interest to be so transferred, and the Security Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of the Global Note from which such interest is being transferred.

Notwithstanding any other provisions of this Supplemental Indenture (other than the provisions set forth in Section 2.13), a Global Note may not be transferred as a whole except by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository.

Such written certification shall no longer be required after the expiration of the Restricted Period. In the case of a transfer of a beneficial interest in a Regulation S Global Note for an interest in a Rule 144A Global Note, the transferee must, at the request of the Company, deliver an opinion of counsel reasonably acceptable to the Company stating that the proposed transfer is being made pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act.

(e) By its acceptance of any Senior Note bearing any legend in Section 2.12(d), each Holder of such Senior Note acknowledges the restrictions on transfer of such Senior Note set forth in this Indenture and in such legend in Section 2.13(d) and agrees that it shall transfer such Senior Note only as provided in this Indenture.

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).

(d) The Trustee shall terminate the Account Control Agreement relating to each Segregated Collateral Account upon or promptly following the Trigger Date.

(b) The obligations of each Guarantor hereunder shall continue to be effective or shall be reinstated, as the case may be, if at any time any payment which would otherwise have reduced or terminated the obligations of any Guarantor hereunder and under its Guarantee (whether such payment shall have been made by or on behalf of the Company or by or on behalf of a Guarantor) is rescinded or reclaimed from any of the Holders upon the insolvency, bankruptcy, liquidation or reorganization of the Company or any Guarantor or otherwise, all as though such payment had not been made.

Section 4.04 Notation Not Required.

Neither the Company nor any Guarantor shall be required to make a notation on the Senior Notes to reflect any Guarantee or any release thereof.

Section 4.05 Waiver of Subrogation.

(a) Each Guarantor hereby irrevocably waives any claim or other rights which it may now or hereafter acquire against the Company that arise from the existence, payment, performance or enforcement of such Guarantor's obligations under its Guarantee and the Indenture, including, without limitation, any right of subrogation, reimbursement, exoneration, indemnification, and any right to participate in any claim or remedy of any Holder of Senior Notes against the Company, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law, including, without limitation, the right to take or receive from the Company, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim or other rights in relation to the Trustee until all monetary obligations of the Company under the Indenture (with respect to the Senior Notes) and the Senior Notes, whether for principal of or interest on the Senior Notes, are paid in full.

HALFMOON PARENT, INC., 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 17, 2020 and to pay interest thereon accruing from September 17, 2018, or from the most recent date to which interest has been paid or duly provided for, quarterly in arrears on March 17, June 17, September 17 and December 17 of each year, commencing on December 17, 2018, and on the Maturity of this Security, (each, an "Interest Payment Date") at the rate, reset quarterly, equal to LIBOR (as determined on the Interest Determination Date in accordance with the next succeeding paragraphs) plus 0.350% per annum, until the principal hereof is paid or made available for payment. 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 fifteen (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 at the relevant Maturity will be payable to the Persons to whom the principal of this Security is payable). If an Interest Payment Date (other than any Maturity) is not a Business Day, then such Interest Payment Date shall be the next succeeding Business Day, unless the next succeeding Business Day is in the next succeeding calendar month, in which case such Interest Payment Date shall be the immediately preceding Business Day. If the relevant Maturity of this Security falls on a day that is not a Business Day, the payment of principal and interest, if any, otherwise payable on such date will be postponed to the next succeeding Business Day, and no interest on such payment will accrue from and after such Maturity. 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 ten (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.

Annex 1 - 3

This Security will bear interest for each Interest Period at a rate determined by U.S. Bank National Association, acting as calculation agent, or any successor thereto, including a successor appointed as set forth below (the "Calculation Agent"). The interest rate on this Security for each day of an Interest Period will be a rate equal to LIBOR as determined on the Interest Determination Date (as defined below) plus 0.350% per year.

The interest rate for each Interest Period will be reset on March 17, June 17, September 17 and December 17 of each year (each such date, an "Interest Reset Date"), and will be set for the initial Interest Period on September 17, 2018. If any Interest Reset Date would otherwise be a day that is not a Business Day, such Interest Reset Date shall be the next succeeding Business Day, unless the next succeeding Business Day is in the next succeeding calendar month, in which case such Interest Reset Date shall be the immediately preceding Business Day.

The initial Interest Period for this Security will be the period from and including September 17, 2018 to, but excluding, the first Interest Reset Date. Thereafter, an "Interest Period" shall mean the period from and including an Interest Reset Date to, but excluding, the next succeeding Interest Reset Date and, in the case of the last such period, from and including the Interest Reset Date immediately preceding Maturity, but excluding, such Maturity.

The "Interest Determination Date" for the initial Interest Period will be the date that is the second London Business Day preceding the date of original issuance of the Floating Rate Notes and for any other Interest Period will be the second London Business Day preceding the relevant Interest Reset Date.

A "London Business Day" is a day on which dealings in deposits in U.S. dollars are transacted in the London interbank market.

Promptly upon determination, the Calculation Agent will inform the Company of the interest rate for the next Interest Period.

Absent manifest error, the determination of the interest rate by the Calculation Agent shall be conclusive and binding on the Holders of this Security, the Trustee and the Company. So long as LIBOR is required to be determined with respect to the this Security, there will at all times be a Calculation Agent. In the event that any then acting Calculation Agent shall be unable or unwilling to act, or that such Calculation Agent shall fail to duly establish LIBOR for any Interest Period, or that the Company proposes to remove such Calculation Agent, the Company shall appoint another Person which is a bank, trust company, investment banking firm or other financial institution to act as the Calculation Agent.

On any Interest Determination Date, LIBOR will be equal to the offered rate for deposits in U.S. dollars having an index maturity of three months as such rate appears on "Reuters Page LIBOR01" at approximately 11:00 a.m., London time, on such Interest Determination Date. If on an Interest Determination Date, such rate does not appear on the "Reuters Page LIBOR01" at approximately 11:00 a.m., London time, or if "Reuters Page LIBOR01" is not available at such time, the Calculation Agent will obtain such rate from Bloomberg L.P.'s page "BBAM."

Annex 1 - 4

Subject to the immediately following paragraph, if no offered rate appears on "Reuters Page LIBOR01" or Bloomberg L.P.'s page "BBAM" on an Interest Determination Date at approximately 11:00 a.m., London time, then the Company will select four major banks in the London interbank market and shall request each of their principal London offices to provide to the Calculation Agent a quotation of the rate at which three-month deposits in U.S. dollars in amounts of at least $1 million are offered by it to prime banks in the London interbank market, on that date and at that time, that is representative of single transactions at that time. If at least two quotations are provided, LIBOR will be the arithmetic average of the quotations provided. Otherwise, the Company will select three major banks in New York City and shall request each of them to provide to the Calculation Agent a quotation of the rate offered by them at approximately 11:00 a.m., New York City time, on the Interest Determination Date for loans in U.S. dollars to leading European banks having an index maturity of three months for the applicable Interest Period in an amount of at least $1 million that is representative of single transactions at that time. If three quotations are provided, LIBOR will be the arithmetic average of the quotations provided. Otherwise, the rate of LIBOR for the next Interest Period will be set equal to the rate of LIBOR for the then current Interest Period.

Notwithstanding the paragraph immediately above, if the Company, in its sole discretion, determines that LIBOR has been permanently discontinued and the Company has notified the Calculation Agent of such determination (a "LIBOR Event"), the Calculation Agent will use, as directed by the Company, as a substitute for LIBOR (the "Alternative Rate") for each future floating rate Interest Determination Date, the alternative reference rate selected by the central bank, reserve bank, monetary authority or any similar institution (including any committee or working group thereof) that is consistent with market practice regarding a substitute for LIBOR. As part of such substitution, the Calculation Agent will, as directed by the Company, make such adjustments to the Alternative Rate or the spread thereon, as well as the business day convention, interest determination dates and related provisions and definitions ("Adjustments"), in each case that are consistent with market practice for the use of such Alternative Rate. Notwithstanding the foregoing, if the Company determines that there is no alternative reference rate selected by the central bank, reserve bank, monetary authority or any similar institution (including any committee or working group thereof) that is consistent with market practice regarding a substitute for LIBOR, the Company may, in its sole discretion, appoint an independent financial advisor ("IFA") to determine an appropriate Alternative Rate and any Adjustments, and the decision of the IFA will be conclusive and binding on the Company, the Calculation Agent, the Trustee and the Holders of this Security. If a LIBOR Event has occurred, but for any reason an Alternative Rate has not been determined or there is no such market practice for the use of such Alternative Rate (and, in each case, an IFA has not determined an appropriate Alternative Rate and Adjustments), the rate of LIBOR for the next Interest Period will be set equal to the rate of LIBOR for the then current Interest Period.

The amount of interest for each day that this Security is Outstanding (the "Daily Interest Amount") will be calculated by dividing the interest rate in effect on this Security for such day for such series by 360 and multiplying the result by the principal amount of this Security (known as the "Actual/360" day count). The amount of interest to be paid on this Security for any Interest Period will be calculated by adding the Daily Interest Amounts for each day in such Interest Period.

Annex 1 - 5

Notwithstanding the foregoing or anything to the contrary provided herein, the interest rate on this Security will be limited to the maximum rate permitted by New York law, as the same may be modified by United States law of general application.

All percentages resulting from any calculation of any interest rate this Security will be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upward (e.g., 9.876545% (or .09876545) would be rounded to 9.87655% (or .0987655)), and all U.S. dollar amounts will be rounded to the nearest cent, with one-half cent being rounded upward.

Upon prior written request from any Holder of this Security, the Calculation Agent will provide the interest rate in effect on this Security for the current Interest Period and, if it has been determined, the interest rate to be in effect for the next Interest Period.

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.

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.

[REVERSE SIDE OF SECURITY]

HALFMOON PARENT, INC.
Senior Floating Rate Notes due 2020

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. 1, dated as of September 17, 2018 (the "Supplemental Indenture" and, together with the Base Indenture and as may be further amended and supplemented, 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 $1,000,000,000, subject to future issuances of additional Securities pursuant to Section 3.01 of the Base Indenture.

If (x) the consummation of the Acquisition (as defined below) does not occur on or before September 4, 2019 or (y) the Company notifies the Trustee that the Company will not pursue the consummation of the Acquisition (the "Special Mandatory Redemption Trigger Date"), the Company will be required to redeem the Securities of this series then Outstanding (such redemption, the "Special Mandatory Redemption") at a redemption price equal to 101% of the principal amount of the Securities of this series plus accrued and unpaid interest, if any, to, but excluding, the Special Mandatory Redemption Date (the "Special Mandatory Redemption Price").

In the event that the Company becomes obligated to redeem the Securities of this series pursuant to the Special Mandatory Redemption, the Company will promptly, and in any event not more than five (5) business days after the Special Mandatory Redemption Trigger Date, deliver notice to the Trustee of the Special Mandatory Redemption and the date upon which the Securities of this series will be redeemed (the "Special Mandatory Redemption Date," which date shall be no later than the third (3rd) Business Day following the date of such notice) together with a notice of Special Mandatory Redemption for the Trustee to deliver to each registered Holder of the Securities of this series to be redeemed. The Trustee will then promptly mail, or electronically deliver, according to the procedures of the Depository, such notice of Special Mandatory Redemption to each registered Holder of the Securities of this series to be redeemed. Unless the Company defaults in payment of the Special Mandatory Redemption Price, on and after such Special Mandatory Redemption Date, interest will cease to accrue on the Securities of this series to be redeemed.

Notwithstanding the foregoing, installments of interest on Securities of this series that are due and payable on Interest Payment Dates falling on or prior to the Special Mandatory Redemption Date will be payable on such Interest Payment Dates to the registered Holders as of the close of business on the relevant record dates in accordance with the Securities and the Indenture.

Annex 1 - 9

"Acquisition" means the acquisition by the Company of Cigna and its subsidiaries and Express Scripts and its subsidiaries.

If a Change of Control Triggering Event occurs with respect to Securities of this series, 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 Securities of this series to repurchase any and all of such Holder's Securities of this series at a repurchase price in cash equal to 101% of the aggregate principal amount of the Securities of this series repurchased plus accrued and unpaid interest, if any, thereon, to but excluding the date of repurchase (the "Change of Control Payment"). Within thirty (30) days following any Change of Control Triggering Event, the Company will mail (or otherwise deliver in accordance with the applicable procedures of the Depository) 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 fifteen (15) days and no more than sixty (60) days from the date such notice is mailed (or otherwise delivered in accordance with the applicable procedures of the Depository) (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 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, 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 by virtue of such conflicts.

The Company will not be required to offer to repurchase the Securities 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 properly tendered and not withdrawn under its offer; provided that for all purposes of the Securities 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 unless the Company promptly makes an offer to repurchase the Securities at 101% of the principal amount thereof plus accrued and unpaid interest, if any, thereon, to the date of repurchase, which shall be no later than thirty (30) days after the third party's scheduled Change of Control Payment Date.

Annex 1 - 10

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 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 properly tendered; and

●	deliver or cause to be delivered to the Trustee the Securities properly accepted, together with an Officers' Certificate stating the principal amount of Securities being purchased.

"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 such series of Securities, 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 such series of Securities 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).

Annex 1 - 11

"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.

"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 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.

Annex 1 - 12

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.

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.

Annex 1 - 13

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.

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 fifteen (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 at 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.

At any time prior to June 15, 2048, the Company may redeem Securities of this series, in whole or in part, at a redemption price equal to the greater of (i) 100% of the principal amount of the Securities of this series 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 of this series to be redeemed from the Redemption Date to June 15, 2048, discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus 30 basis points, plus, in each case, accrued and unpaid interest, if any, on the principal amount of the Securities being redeemed to but excluding the Redemption Date (the "Fixed Rate Make Whole Redemption Price").
