PHILLIPS 66 Floating Rate Senior Notes due 2024 Fully and Unconditionally Guaranteed by PHILLIPS 66 COMPANY

One series of Securities is hereby established pursuant to Section 2.01 of the Indenture, dated as of April 9, 2020 (the “Indenture”), among Phillips 66, as issuer (the “Company”), Phillips 66 Company, as guarantor (the “Guarantor”), and U.S. Bank National Association, as trustee (the “Trustee”), as follows:

1.    Each capitalized term used but not defined herein shall have the meaning assigned to such term in the Indenture.

2.    The title of the Floating Rate Senior Notes due 2024 shall be “Floating Rate Senior Notes due 2024” (the “Notes”).

3.    The limit upon the aggregate principal amount of the Notes that may be authenticated and delivered under the Indenture (except for the Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Notes pursuant to Section 2.08, 2.09, 2.12, 2.17, 3.07 or 9.05 of the Indenture and except for any Notes which, pursuant to Section 2.04 or 2.17 of the Indenture, are deemed never to have been authenticated and delivered thereunder) is $450,000,000; provided, however, that the authorized aggregate principal amount of the Notes may be increased before or after the issuance of any Notes by a Board Resolution (or action pursuant to a Board Resolution) to such effect; provided further, however, that the authorized aggregate principal amount of the Notes may be increased only if the additional Notes issued will be fungible with the original Notes for United States federal income tax purposes.

4.    The Notes shall be issued upon original issuance in whole in the form of one or more Global Securities (the “Global Notes”). The Depository Trust Company and the Trustee are hereby designated as the Depositary and the Security Custodian, respectively, for the Global Notes under the Indenture.

5.    The Notes and the Trustee’s certificate of authentication shall be substantially in the form of Annex A hereto (the “Form of Note”).

6.    The date on which the principal of the Notes is payable shall be February 15, 2024.

7.    The Notes shall bear interest for each interest period at a rate equal to three-month USD London Interbank Offered Rate (“three-month LIBOR”) plus a margin of 0.62% per annum, as determined by the calculation agent for the Notes (the “Calculation Agent”), which will initially be U.S. Bank National Association, on the second London business day preceding that interest period (the “Interest Determination Date”) from November 18, 2020 until February 15, 2024 (“Maturity”). The Company will pay interest quarterly on February 15, May 15, August 15, and November 15 of each year except as any such date may be adjusted as specified below (each

an “Interest Payment Date”). A London business day is a day on which dealings in deposits in U.S. dollars are transacted in the London interbank market. Interest on the Notes will accrue from the most recent Interest Payment Date to which interest has been paid or provided for, or, if no interest has been paid or provided for, from November 18, 2020 to the next succeeding Interest Payment Date (each, an “interest period”); provided that that if an Interest Payment Date (other than the date of Maturity) for the Notes falls on a day that is not a Business Day, the Interest Payment Date shall be postponed to the next succeeding Business Day unless such next succeeding Business Day would be in the following month, in which case, the Interest Payment Date shall be the immediately preceding Business Day and if the date of Maturity of the Notes falls on a day that is not a Business Day, then the related payment of principal and interest will be made on the next day that is a Business Day with the same effect as if made on the date that the payment was first due, and no interest will accrue on the amount so payable for the period from the date of Maturity; provided, further, that the first Interest Payment Date shall be February 15, 2021 and the first Interest Determination Date shall be November 16, 2020. Interest on the Notes will accrue and be paid to but excluding the relevant Interest Payment Date (as so adjusted). This Section 7 shall apply in lieu of Section 11.07 of the Indenture. The initial interest period is November 18, 2020 to, but not including, February 15, 2021. Interest will be computed on the basis of the actual number of days in an interest period and a 360-day year. The interest so payable, and punctually paid or provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name a Note is registered at the close of business on the Record Date for such interest as set forth on the face of the Notes; provided, however, that interest payable at Maturity of a Note will be payable to the Person to whom the principal thereof shall be payable. Any such interest which is so payable, but is not punctually paid or duly provided for on any Interest Payment Date, shall forthwith cease to be payable to the registered Holder on such Record Date, and may be paid as more fully provided in the Indenture. Promptly upon determination, the Calculation Agent will inform the Trustee and the Company, or, if the Company (or its Designee (as defined below)) has determined that a Benchmark Transition Event and its related Benchmark Transition Date have occurred with respect to three-month LIBOR, the Company (or its Designee) will inform the Trustee, of the interest rate for the next interest period. Absent manifest error, the determination of the interest rate by the Calculation Agent, or, if the Company (or its Designee) has determined that a Benchmark Transition Event and its related Benchmark Transition Date have occurred with respect to three-month LIBOR, by the Company (or its Designee), shall be binding and conclusive on the holders of the Notes, the Trustee and the Company.

On any Interest Determination Date, “three-month LIBOR” will be equal to the offered rate for deposits in U.S. dollars having an index maturity of three months, in amounts of at least $1,000,000, as such rate appears on “Reuters Page LIBOR01” at approximately 11:00 a.m., London time, on such Interest Determination Date, except as otherwise specified below.

“Reuters Page LIBOR01” means the display designated as “LIBOR01” on Reuters (or any successor service) (or such other page as may replace Page LIBOR01 on Reuters or any successor service).

Upon written request from any holder of the Notes, the Calculation Agent or, if the Company (or its Designee) has determined that a Benchmark Transition Event and its related Benchmark Transition Date have occurred with respect to three-month LIBOR, the Company (or

its Designee) will provide the interest rate in effect for the Notes for the current interest period and, if it has been determined, the interest rate to be in effect for the next interest period.

All percentages resulting from any of the above calculations will be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point being rounded upwards (e.g., 8.986865% (or 0.08986865) being rounded to 8.98687% (or 0.0898687)) and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upwards).

If no offered rate appears on Reuters Page LIBOR01 on an Interest Determination Date at approximately 11:00 a.m., London time, or three-month LIBOR cannot otherwise be determined as described above, then the Calculation Agent for the Notes (after consultation with the Company) shall determine three-month LIBOR as follows:

(A)    The Company shall select four major banks in the London interbank market (whose name and contact information the Company shall provide to the Calculation Agent) and shall request that the principal London offices of those four selected banks provide their offered quotations to prime banks in the London interbank market at approximately 11:00 a.m., London time, on the Interest Determination Date. These quotations shall be for deposits in USD for the period of three months, commencing on the Interest Determination Date, and such offered quotations must be based on a principal amount equal to at least $1,000,000 that is representative of a single transaction in such market at that time. If two or more quotations are provided, three-month LIBOR for the interest period will be the arithmetic average of those quotations.

(B)    If fewer than two quotations are provided, the Company will select three major banks in New York City (whose name and contact information the Company shall provide to the Calculation Agent) and then if three of such New York City banks are quoting rates the Calculation Agent shall determine three-month LIBOR for the interest period as the arithmetic average of rates quoted by those three major banks in New York City to leading European banks at approximately 11:00 a.m., New York City time, on the Interest Determination Date. The rates quoted must be for loans in USD for the period of three months, commencing on the Interest Determination Date and must be based on a principal amount of at least $1,000,000 that is representative of a single transaction in such market at that time.

(C) If fewer than three New York City banks selected by the Company are quoting rates, three-month LIBOR for the interest period will be the same as for the immediately preceding interest period.

Notwithstanding the foregoing, if the Company or a designee of the Company acting as an agent of the Company (which designee may be the Calculation Agent only if the Calculation Agent consents in writing to such appointment in its sole discretion with no liability therefor, a successor calculation agent, an independent financial advisor or any other such designee) (any of such entities, a “Designee”) determines on or prior to the relevant Interest Determination Date that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to three-month LIBOR, then the Company or its Designee, as applicable, shall promptly provide notice of such determination to the Trustee and the Calculation Agent and the provisions

set forth below under “Effect of a Benchmark Transition Event,” which are referred to as the benchmark transition provisions, will thereafter apply to all determinations, calculations and quotations made or obtained for the purposes of calculating the rate and amount of interest payable on the Notes during a relevant interest period. In accordance with the benchmark transition provisions, after the Company (or its Designee) determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, the amount of interest that will be payable for each interest period will be an annual rate equal to the sum of the Benchmark Replacement and 0.62% as determined by the Company (or its Designee) and promptly upon such determination the Company (or its Designee) will inform the Trustee of such rate.

However, if the Company (or its Designee) determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to the then-current Benchmark, but for any reason the Benchmark Replacement has not been determined by the Company (or its Designee) as of the relevant Interest Determination Date, the interest rate for the applicable interest period will be equal to the same interest rate as for the immediately preceding interest period for the Notes, as determined by the Company (or its Designee), and the Company or its Designee, as applicable, shall promptly provide notice of such determination to the Trustee and the Calculation Agent.

Benchmark Replacement. If the Company (or its Designee) determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any determination of the Benchmark on any date, the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Notes in respect of such determination on such date and all determinations on all subsequent dates.

Benchmark Replacement Conforming Changes. In connection with the implementation of a Benchmark Replacement, the Company (or its Designee) will have the right to make Benchmark Replacement Conforming Changes from time to time.

Decisions and Determinations. Any determination, decision or election that may be made by the Company (or its Designee) pursuant to this Section titled “Effect of a Benchmark Transition Event,” including any determination with respect to tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection, will be conclusive and binding absent manifest error, will be made in the Company’s (or its Designee’s) sole discretion, and, notwithstanding anything to the contrary in the documentation relating to the Notes, shall become effective without consent from the holders of the Notes or any other party.

Certain Defined Terms. As used herein:

“Benchmark” means, initially, three-month LIBOR; provided that if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to three-month LIBOR or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement.

“Benchmark Replacement” means the Interpolated Benchmark with respect to the then-current Benchmark, plus the Benchmark Replacement Adjustment for such Benchmark; provided that if the Company (or its Designee) cannot determine the Interpolated Benchmark as of the Benchmark Replacement Date, then “Benchmark Replacement” means the first alternative set forth in the order below that can be determined by the Company (or its Designee) as of the Benchmark Replacement Date:

(1)    the sum of: (a) Term SOFR and (b) the Benchmark Replacement Adjustment;

(2)    the sum of: (a) Compounded SOFR and (b) the Benchmark Replacement Adjustment;

(3)    the sum of: (a) the alternate rate of interest that has been selected or recommended by the Relevant Governmental Body as the replacement for the then-current Benchmark for the applicable Corresponding Tenor and (b) the Benchmark Replacement Adjustment;

(4)    the sum of: (a) the ISDA Fallback Rate and (b) the Benchmark Replacement Adjustment; and

(5)    the sum of: (a) the alternate rate of interest that has been selected by the Company (or its Designee) as the replacement for the then-current Benchmark for the applicable Corresponding Tenor giving due consideration to any industry-accepted rate of interest as a replacement for the then-current Benchmark for U.S. dollar denominated floating rate notes at such time and (b) the Benchmark Replacement Adjustment.

“Benchmark Replacement Adjustment” means the first alternative set forth in the order below that can be determined by the Company (or its Designee) as of the Benchmark Replacement Date:

(1)    the spread adjustment, or method for calculating or determining such spread adjustment (which may be a positive or negative value or zero), that has been selected or recommended by the Relevant Governmental Body for the applicable Unadjusted Benchmark Replacement;

(2)    if the applicable Unadjusted Benchmark Replacement is equivalent to the ISDA Fallback Rate, then the ISDA Fallback Adjustment; and

(3)    the spread adjustment (which may be a positive or negative value or zero) that has been selected by the Company (or its Designee) giving due consideration to any industry-accepted spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of the then-current Benchmark with the applicable Unadjusted Benchmark Replacement for U.S. dollar denominated floating rate notes at such time.

“Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definition of “interest period,” timing and frequency of determining rates and making payments of interest, rounding of amounts or tenors, changes to the definition of “Corresponding Tenor” solely

when such tenor is longer than the interest period and other administrative matters) that the Company (or its Designee) decides may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Company (or its Designee) decides that adoption of any portion of such market practice is not administratively feasible or if the Company (or its Designee) determines that no market practice for use of the Benchmark Replacement exists, in such other manner as the Company (or its Designee) determines is reasonably necessary).

“Benchmark Replacement Date” means the earliest to occur of the following events with respect to the then-current Benchmark:

(1)    in the case of clause (1) or (2) of the definition of “Benchmark Transition Event,” the later of (a) the date of the public statement or publication of information referenced therein and (b) the date on which the administrator of the Benchmark permanently or indefinitely ceases to provide the Benchmark; or

(2)    in the case of clause (3) of the definition of “Benchmark Transition Event,” the date of the public statement or publication of information referenced therein.

For the avoidance of doubt, if the event giving rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination.

“Benchmark Transition Event” means the occurrence of one or more of the following events with respect to the then-current Benchmark:

(1)    a public statement or publication of information by or on behalf of the administrator of the Benchmark announcing that such administrator has ceased or will cease to provide the Benchmark, permanently or indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark;

(2)    a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark, the central bank for the currency of the Benchmark, an insolvency official with jurisdiction over the administrator for the Benchmark, a resolution authority with jurisdiction over the administrator for the Benchmark or a court or an entity with similar insolvency or resolution authority over the administrator for the Benchmark, which states that the administrator of the Benchmark has ceased or will cease to provide the Benchmark permanently or indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark; or

(3)    a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark announcing that the Benchmark is no longer representative.

“Compounded SOFR” means the compounded average of SOFRs for the applicable Corresponding Tenor, with the rate, or methodology for this rate, and conventions for this rate being established by the Company (or its Designee) in accordance with:

(1)    the rate, or methodology for this rate, and conventions for this rate selected or recommended by the Relevant Governmental Body for determining Compounded SOFR; provided that:

(2)    if, and to the extent that, the Company (or its Designee) determines that Compounded SOFR cannot be determined in accordance with clause (1) above, then the rate, or methodology for this rate, and conventions for this rate that have been selected by the Company (or its Designee) giving due consideration to any industry-accepted market practice for U.S. dollar denominated floating rate notes at such time.

For the avoidance of doubt, the calculation of Compounded SOFR shall exclude the Benchmark Replacement Adjustment and the margin of 0.62% referenced above.

“Corresponding Tenor” with respect to a Benchmark Replacement means a tenor (including overnight) having approximately the same length (disregarding business day adjustment) as the applicable tenor for the then-current Benchmark.

“Federal Reserve Bank of New York’s Website” means the website of the Federal Reserve Bank of New York at http://www.newyorkfed.org, or any successor source.

“Interpolated Benchmark” with respect to the Benchmark means the rate determined for the Corresponding Tenor by interpolating on a linear basis between: (1) the Benchmark for the longest period (for which the Benchmark is available) that is shorter than the Corresponding Tenor and (2) the Benchmark for the shortest period (for which the Benchmark is available) that is longer than the Corresponding Tenor.

“ISDA Definitions” means the 2006 ISDA Definitions published by the International Swaps and Derivatives Association, Inc. or any successor thereto, as amended or supplemented from time to time, or any successor definitional booklet for interest rate derivatives published from time to time.

“ISDA Fallback Adjustment” means the spread adjustment (which may be a positive or negative value or zero) that would apply for derivatives transactions referencing the ISDA Definitions to be determined upon the occurrence of an index cessation event with respect to the Benchmark for the applicable tenor.

“ISDA Fallback Rate” means the rate that would apply for derivatives transactions referencing the ISDA Definitions to be effective upon the occurrence of an index cessation date with respect to the Benchmark for the applicable tenor excluding the applicable ISDA Fallback Adjustment.

“Reference Time” with respect to any determination of the Benchmark means (1) if the Benchmark is three-month LIBOR, 11:00 a.m. (London time) on the day that is two London banking days preceding the date of such determination, and (2) if the Benchmark is not three-month LIBOR, the time determined by the Company (or its Designee) in accordance with the Benchmark Replacement Conforming Changes.

8.    Notwithstanding the foregoing, the interest rate in any interest period shall in no event be higher than the maximum rate permitted by New York law, as the same may be modified by United States law of general application. The minimum interest rate shall not be less than 0.000%.

9.    No Additional Amounts with respect to the Notes shall be payable. The date from which interest shall accrue for the Notes shall be November 18, 2020 (or from the most recent Interest Payment Date to which interest has been paid or provided for).

Payments in respect of Global Notes (including principal, premium, if any, and interest) shall be made by wire transfer of immediately available funds to the accounts specified by the Holder of such Notes. In all other cases, 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 register of the Notes maintained by the Registrar.

Authorized Signatory

Dated:

This Security is one of a duly authorized issue of Floating Rate Senior Notes due 2024 (the “Securities”) of Phillips 66, a Delaware corporation (the “Company”).

1.    Interest. The Company promises to pay interest on the principal amount of this Security for each interest period at a rate equal to three-month USD London Interbank Offered Rate (“three-month LIBOR”) plus a margin of 0.62% per annum, as determined by the calculation agent for the Securities (the “Calculation Agent”), which will initially be U.S. Bank National Association, on the second London business day preceding that interest period (the “Interest Determination Date”) from November 18, 2020 until February 15, 2024 (“Maturity”). The Company will pay interest quarterly on February 15, May 15, August 15, and November 15 of each year except as any such date may be adjusted as specified below (each an “Interest Payment Date”). A London business day is a day on which dealings in deposits in U.S. dollars are transacted in the London interbank market. Interest on the Securities will accrue from the most recent Interest Payment Date to which interest has been paid or provided for, or, if no interest has been paid or provided for, from November 18, 2020 to the next succeeding Interest Payment Date (each, an “interest period”); provided that if an Interest Payment Date (other than the date of Maturity) for the Securities falls on a day that is not a Business Day, the Interest Payment Date shall be postponed to the next succeeding Business Day unless such next succeeding Business Day would be in the following month, in which case, the Interest Payment Date shall be the immediately preceding Business Day and if the date of Maturity of the Securities falls on a day that is not a Business Day, then the related payment of principal and interest will be made on the next day that is a Business Day with the same effect as if made on the date that the payment was first due, and no interest will accrue on the amount so payable for the period from the date of Maturity; provided, further, that the first Interest Payment Date shall be February 15, 2021 and the first Interest Determination Date shall be November 16, 2020. Interest on the Securities will accrue and be paid to but excluding the relevant Interest Payment Date (as so adjusted). This Section 1 shall apply in lieu of Section 11.07 of the Indenture. The initial interest period is November 18, 2020 to, but not including, February 15, 2021. Interest will be computed on the basis of the actual number of days in an interest period and a 360-day year. The interest so payable, and punctually paid or provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name this Security is registered at the close of business on the Record Date for such interest as set forth on the face hereof; provided, however, that interest payable at Maturity of this Security will be payable to the Person to whom the principal hereof shall be payable. Any such interest which is so payable, but is not punctually paid or duly provided for on any Interest Payment Date, shall forthwith cease to be payable to the registered Holder on such Record Date,

and may be paid as more fully provided in the Indenture. Promptly upon determination, the Calculation Agent will inform the Trustee and the Company, or, if the Company (or its Designee (as defined below)) has determined that a Benchmark Transition Event and its related Benchmark Transition Date have occurred with respect to three-month LIBOR, the Company (or its Designee) will inform the Trustee, of the interest rate for the next interest period. Absent manifest error, the determination of the interest rate by the Calculation Agent, or, if the Company (or its Designee) has determined that a Benchmark Transition Event and its related Benchmark Transition Date have occurred with respect to three-month LIBOR, by the Company (or its Designee), shall be binding and conclusive on the holders of the Securities, the Trustee and the Company.

On any Interest Determination Date, “three-month LIBOR” will be equal to the offered rate for deposits in U.S. dollars having an index maturity of three months, in amounts of at least $1,000,000, as such rate appears on “Reuters Page LIBOR01” at approximately 11:00 a.m., London time, on such Interest Determination Date, except as otherwise specified below.

“Reuters Page LIBOR01” means the display designated as “LIBOR01” on Reuters (or any successor service) (or such other page as may replace Page LIBOR01 on Reuters or any successor service).

Upon written request from any holder of the Securities, the Calculation Agent or, if the Company (or its Designee) has determined that a Benchmark Transition Event and its related Benchmark Transition Date have occurred with respect to three-month LIBOR, the Company (or its Designee) will provide the interest rate in effect for the Securities for the current interest period and, if it has been determined, the interest rate to be in effect for the next interest period.

All percentages resulting from any of the above calculations will be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point being rounded upwards (e.g., 8.986865% (or 0.08986865) being rounded to 8.98687% (or 0.0898687)) and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upwards).

If no offered rate appears on Reuters Page LIBOR01 on an Interest Determination Date at approximately 11:00 a.m., London time, or three-month LIBOR cannot otherwise be determined as described above, then the Calculation Agent for the Securities (after consultation with the Company) shall determine three-month LIBOR as follows:

(A)    The Company shall select four major banks in the London interbank market (whose name and contact information the Company shall provide to the Calculation Agent) and shall request that the principal London offices of those four selected banks provide their offered quotations to prime banks in the London interbank market at approximately 11:00 a.m., London time, on the Interest Determination Date. These quotations shall be for deposits in USD for the period of three months, commencing on the Interest Determination Date, and such offered quotations must be based on a principal amount equal to at least $1,000,000 that is representative of a single transaction in such market at that time. If two or more quotations are provided, three-month LIBOR for the interest period will be the arithmetic average of those quotations.

(B)    If fewer than two quotations are provided, the Company will select three major banks in New York City (whose name and contact information the Company shall provide to the Calculation Agent) and then if three of such New York City banks are quoting rates the Calculation Agent shall determine three-month LIBOR for the interest period as the arithmetic average of rates quoted by those three major banks in New York City to leading European banks at approximately 11:00 a.m., New York City time, on the Interest Determination Date. The rates quoted must be for loans in USD for the period of three months, commencing on the Interest Determination Date and must be based on a principal amount of at least $1,000,000 that is representative of a single transaction in such market at that time.

(C) If fewer than three New York City banks selected by the Company are quoting rates, three-month LIBOR for the interest period will be the same as for the immediately preceding interest period.

Notwithstanding the foregoing, if the Company or a designee of the Company acting as an agent of the Company (which designee may be the Calculation Agent only if the Calculation Agent consents in writing to such appointment in its sole discretion with no liability therefor, a successor calculation agent, an independent financial advisor or any other such designee) (any of such entities, a “Designee”) determines on or prior to the relevant Interest Determination Date that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to three-month LIBOR, then the Company or its Designee, as applicable, shall promptly provide notice of such determination to the Trustee and the Calculation Agent and the provisions set forth below under “Effect of a Benchmark Transition Event,” which are referred to as the benchmark transition provisions, will thereafter apply to all determinations, calculations and quotations made or obtained for the purposes of calculating the rate and amount of interest payable on the Securities during a relevant interest period. In accordance with the benchmark transition provisions, after the Company (or its Designee) determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, the amount of interest that will be payable for each interest period will be an annual rate equal to the sum of the Benchmark Replacement and 0.62% as determined by the Company (or its Designee) and promptly upon such determination the Company (or its Designee) will inform the Trustee of such rate.

However, if the Company (or its Designee) determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to the then-current Benchmark, but for any reason the Benchmark Replacement has not been determined by the Company (or its Designee) as of the relevant Interest Determination Date, the interest rate for the applicable interest period will be equal to the same interest rate as for the immediately preceding interest period for the Securities, as determined by the Company (or its Designee), and the Company or its Designee, as applicable, shall promptly provide notice of such determination to the Trustee and the Calculation Agent.

Benchmark Replacement. If the Company (or its Designee) determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any determination of the Benchmark on any date, the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Securities in respect of such determination on such date and all determinations on all subsequent dates.

Benchmark Replacement Conforming Changes. In connection with the implementation of a Benchmark Replacement, the Company (or its Designee) will have the right to make Benchmark Replacement Conforming Changes from time to time.

Decisions and Determinations. Any determination, decision or election that may be made by the Company (or its Designee) pursuant to this Section titled “Effect of a Benchmark Transition Event,” including any determination with respect to tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection, will be conclusive and binding absent manifest error, will be made in the Company’s (or its Designee’s) sole discretion, and, notwithstanding anything to the contrary in the documentation relating to these Securities, shall become effective without consent from the holders of these Securities or any other party.

Certain Defined Terms. As used herein:

(1)    the sum of: (a) Term SOFR and (b) the Benchmark Replacement Adjustment;

(2)    the sum of: (a) Compounded SOFR and (b) the Benchmark Replacement Adjustment;

“Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definition of “interest period,” timing and frequency of determining rates and making payments of interest, rounding of amounts or tenors, changes to the definition of “Corresponding Tenor” solely when such tenor is longer than the interest period and other administrative matters) that the Company (or its Designee) decides may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Company (or its Designee) decides that adoption of any portion of such market practice is not administratively feasible or if the Company (or its Designee) determines that no market practice for use of the Benchmark Replacement exists, in such other manner as the Company (or its Designee) determines is reasonably necessary).

“Benchmark Replacement Date” means the earliest to occur of the following events with respect to the then-current Benchmark:

(3)    a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark announcing that the Benchmark is no longer representative.

For the avoidance of doubt, the calculation of Compounded SOFR shall exclude the Benchmark Replacement Adjustment and the margin of 0.62% referenced above.

2.    Method of Payment. The Company shall pay interest on the Securities (except defaulted interest) to the Persons who are registered Holders of Securities at the close of business on the Record Date next preceding the Interest Payment Date, even if such Securities are canceled after such Record Date and on or before such Interest Payment Date. The Holder must surrender this Security to a Paying Agent to collect principal payments. The Company shall pay the principal of, premium (if any) on and interest on the Securities in money of the United States of America that at the time of payment is legal tender for payment of public and private debts.

3.    Paying Agent and Registrar. Initially, U.S. Bank National Association (the “Trustee”), the trustee under the Indenture, will act as Paying Agent and Registrar.

In the event of a default in the payment of principal of or any premium on the Securities when and as the same shall become due, whether at the Stated Maturity thereof, by acceleration, call for redemption or otherwise, or in the event of a default in the payment of any interest on the Securities when and as the same shall become due, subject to any applicable grace period, each of the Trustee and the Holders of the Securities shall have the right to proceed first and directly against the Guarantor under the Indenture without first proceeding against the Company or exhausting any other remedies which the Trustee or such Holder may have and without resorting to any other security held by it.

5.    Indenture. The Company issued the Securities under an Indenture, dated as of April 9, 2020 (the “Indenture”), among the Company, the Guarantor and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “TIA”), as in effect on the date of execution of the Indenture. The Securities are subject to all such terms, and Holders are referred

to the Indenture and the TIA for a statement of such terms and for the definitions of capitalized terms used but not defined herein. The Securities are unsecured general obligations of the Company limited to $450,000,000 in aggregate principal amount; provided, however, that the authorized aggregate principal amount of the Securities may be increased before or after the issuance of any Securities by a Board Resolution (or action pursuant to a Board Resolution) to such effect; provided further, however, that the authorized aggregate principal amount of the Securities may be increased only if the additional Securities issued will be fungible with the original Securities for United States federal income tax purposes. The Indenture provides for the issuance of other series of debt securities (including the Securities, the “Debt Securities”) thereunder.

6.    Denominations, Transfer, Exchange. The Securities are in registered form without coupons in minimum denominations of $2,000 and any integral multiples of $1,000 above such amount. The transfer of Securities may be registered and Securities may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. Neither the Company, the Trustee nor the Registrar shall be required to register the transfer or exchange of (a) any Security selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part, or (b) any Security during the period beginning 15 Business Days before the mailing of notice of redemption of Securities to be redeemed and ending at the close of business on the day of mailing.

8.    Redemption. On or after November 19, 2021, the Securities are subject to redemption pursuant to Article III of the Indenture, in whole or in part, from time to time, at the option of the Company, in principal amounts of $2,000 and integral multiples of $1,000 above such amount, upon not less than 15 nor more than 60 days’ prior notice as provided in the Indenture, at a Redemption Price equal to 100% of the principal amount of the Securities to be redeemed, plus accrued and unpaid interest thereon to, but not including, the Redemption Date.

9.    Amendments and Waivers. Subject to certain exceptions and limitations, the Indenture or the Securities may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the then outstanding Securities of all series affected by such amendment or supplement (acting as one class), and any existing or past Default or Event of Default under, or compliance with any provision of, the Indenture may be waived (other than any continuing Default or Event of Default in the payment of the principal of, premium (if any) on or interest on the Securities) by the Holders of at least a majority in principal amount of the then outstanding Securities of any series or of all series (acting as one class) in accordance with the terms of the Indenture. Without the consent of any Holder, the Company, the Guarantor and the Trustee may amend or supplement the Indenture or the Securities or waive any provision of either: (i) to cure any ambiguity, omission, defect or inconsistency; (ii) if required, to provide for the assumption of the obligations of the Company or the Guarantor under the Indenture in the case of the merger, consolidation or sale, lease, conveyance, transfer or other disposition of all or substantially all of the assets of the Company or the Guarantor; (iii) to provide for uncertificated Securities in addition to or in place of certificated Securities or to provide for the issuance of bearer Securities (with or

without coupons); (iv) to provide any security for, or to add any guarantees of or additional obligors on, the Securities or the related Guarantees; (v) to comply with any requirement in order to effect or maintain the qualification of the Indenture under the TIA; (vi) to add to the covenants of the Company or the Guarantor for the benefit of the Holders of the Securities, or to surrender any right or power conferred by the Indenture upon the Company or the Guarantor; (vii) to add any additional Events of Default with respect to all or any series of the Debt Securities; (viii) to change or eliminate any of the provisions of the Indenture, provided that no outstanding Security is adversely affected in any material respect; (ix) to establish the form or terms of Securities of any series; (x) to supplement any of the provisions of the Indenture to such extent as shall be necessary to permit or facilitate the defeasance and discharge of the Securities pursuant to the Indenture, provided that no interest of any Holders of Securities is adversely affected in any material respect; or (xi) to evidence and provide for the acceptance of appointment under the Indenture by a successor Trustee with respect to the Securities and to add to or change any of the provisions of the Indenture as shall be necessary to provide for or facilitate the administration of the trusts thereunder by more than one Trustee, pursuant to the requirements of the Indenture.

The right of any Holder to participate in any consent required or sought pursuant to any provision of the Indenture (and the obligation of the Company or the Guarantor to obtain any such consent otherwise required from such Holder) may be subject to the requirement that such Holder shall have been the Holder of record of any Securities with respect to which such consent is required or sought as of a date identified by the Company or the Guarantor in a notice furnished to Holders in accordance with the terms of the Indenture.

Without the consent of each Holder affected, the Company may not (i) reduce the amount of Debt Securities whose Holders must consent to an amendment, supplement or waiver; (ii) reduce the rate of or change the time for payment of interest, including default interest, on any Security; (iii) reduce the principal of or premium on or any mandatory sinking fund payment with respect to, or change the Stated Maturity of, any Security or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon a declaration of acceleration of the Maturity thereof pursuant to the Indenture; (iv) reduce the premium, if any, payable upon the redemption of any Security or change the time at which any Security may or shall be redeemed; (v) change any obligation of the Issuer or a Guarantor to pay Additional Amounts with respect to any Security; (vi) change the coin or currency in which any Security or any premium, interest or Additional Amounts with respect thereto is payable; (vii) impair the right to institute suit for the enforcement of any payment of principal of or premium (if any) or interest on any Security, except as provided in the Indenture; (viii) make any change in the percentage of principal amount of Debt Securities necessary to waive compliance with certain provisions of the Indenture or make any change in the provision for modification; or (ix) waive a continuing Default or Event of Default, each as defined in the Indenture, in the payment of principal of or premium (if any) or interest on the Securities.

A supplemental indenture that changes or eliminates any covenant or other provision of the Indenture which has expressly been included solely for the benefit of one or more particular series of Debt Securities under the Indenture, or which modifies the rights of the Holders of Debt Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under the Indenture of the Holders of Debt Securities of any other series.

10.    Defaults and Remedies. Events of Default are defined in the Indenture and generally include: (i) default for 30 days in payment of any interest on the Securities; (ii) default in any payment of principal of or premium, if any, on the Securities when due and payable; (iii) default by the Company or the Guarantor in compliance with any of its other covenants or agreements in, or provisions of, the Securities or in the Indenture which shall not have been remedied within 90 days after written notice by the Trustee or by the holders of at least 25% in principal amount of the Securities then outstanding (or, in the event that other Debt Securities issued under the Indenture are also affected by the default, then 25% in principal amount of all outstanding Debt Securities so affected); or (iv) certain events involving bankruptcy, insolvency or reorganization of the Company or the Guarantor. If an Event of Default occurs and is continuing, the Trustee by notice to the Company and the Guarantor, or the Holders of at least 25% in principal amount of the then outstanding Securities of the series affected by such Event of Default (or, in the case of an Event of Default described in clause (iii) above, if outstanding Debt Securities of other series are affected by such default, then at least 25% in principal amount of the then outstanding Debt Securities so affected) by notice to the Company, the Guarantor and the Trustee, may declare the principal of and interest on all the Securities to be immediately due and payable, except that in the case of an Event of Default arising from certain events of bankruptcy, insolvency or reorganization of the Company or the Guarantor, all outstanding Debt Securities under the Indenture become due and payable immediately without further action or notice. The amount due and payable upon the acceleration of any Security is equal to 100% of the principal amount thereof plus accrued interest to the date of payment. Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal, premium or interest) if it determines that withholding notice is in their interests. The Company and the Guarantor must furnish annual compliance certificates to the Trustee.

11.    Discharge Prior to Maturity. The Indenture with respect to the Securities shall be discharged and canceled upon the payment of all of the Securities and shall be discharged except for certain obligations upon the irrevocable deposit with the Trustee of any combination of funds and U.S. Government Obligations sufficient for such payment.

12.    Trustee Dealings with Company and Guarantor. The Trustee, in its individual or any other capacity, may become the owner or pledgee of Securities and may make loans to, accept deposits from, and perform services for the Company, the Guarantor or any of their respective Affiliates, and may otherwise deal with the Company, the Guarantor or any such Affiliates, as if it were not Trustee.

13.    No Recourse Against Others. A director, officer, employee, stockholder, partner or other owner of the Company, the Guarantor or the Trustee, as such, shall not have any liability for any obligations of the Company under the Securities, for any obligations of the Guarantor under the Guarantee or for any obligations of the Company, the Guarantor or the Trustee under the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting a Security waives and releases all such liability. The waiver and release shall be part of the consideration for the issue of Securities.

14.    Authentication. This Security shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

15.    CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Securities as a convenience to the Holders of the Securities. No representation is made as to the accuracy of such numbers as printed on the Securities and reliance may be placed only on the other identification numbers printed thereon.

16.    Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).
