The “Final Underlier Level” will be the Closing Level of the Underlier on the Determination Date.

Pursuant to the Calculation Agent Agreement, the Company may appoint a different Calculation Agent from time to time after the initial issuance of this Security without the consent of the Holder of this Security and without notifying the Holder of this Security.

Adjustments to the Underlier

If at any time the method of calculating the Underlier or a Successor Underlier, or the closing level thereof, is changed in a material respect, or if the Underlier or a Successor Underlier is in any other way modified so that such underlier does not, in the opinion of the Calculation Agent, fairly represent the level of such underlier had those changes or modifications not been made, then the Calculation Agent will, at the close of business in New York, New

York, on each date that the closing level of such underlier is to be calculated, make such calculations and adjustments as, in the good faith judgment of the Calculation Agent, may be necessary in order to arrive at a level of an underlier comparable to the Underlier or Successor Underlier as if those changes or modifications had not been made, and the Calculation Agent will calculate the closing level of the Underlier or Successor Underlier with reference to such underlier, as so adjusted. Accordingly, if the method of calculating the Underlier or Successor Underlier is modified so that the level of such underlier is a fraction or a multiple of what it would have been if it had not been modified (e.g., due to a split or reverse split in such equity underlier), then the Calculation Agent will adjust the Underlier or Successor Underlier in order to arrive at a level of such underlier as if it had not been modified (e.g., as if the split or reverse split had not occurred).

Discontinuance of the Underlier

If the Underlier Sponsor discontinues publication of the Underlier, and the Underlier Sponsor or another entity publishes a successor or substitute equity index that the Calculation Agent determines, in its sole discretion, to be comparable to the Underlier (a “Successor Underlier”), then, upon the Calculation Agent’s notification of that determination to the Trustee and the Company, the Calculation Agent will substitute the Successor Underlier as calculated by the relevant Underlier Sponsor or any other entity and calculate the Final Underlier Level as described above. Upon any selection by the Calculation Agent of a Successor Underlier, the Company will cause notice to be given to the Holder of this Security.

In the event that the Underlier Sponsor discontinues publication of the Underlier prior to, and the discontinuance is continuing on, the Determination Date and the Calculation Agent determines that no Successor Underlier is available at such time, the Calculation Agent will calculate a substitute Closing Level for the Underlier in accordance with the formula for and method of calculating the Underlier last in effect prior to the discontinuance, but using only those securities that comprised the Underlier immediately prior to that discontinuance. If a Successor Underlier is selected or the Calculation Agent calculates a level as a substitute for the Underlier, the Successor Underlier or level will be used as a substitute for the Underlier for all purposes, including the purpose of determining whether a Market Disruption Event exists.

If on the Determination Date the Underlier Sponsor fails to calculate and announce the level of the Underlier, the Calculation Agent will calculate a substitute Closing Level of the Underlier in accordance with the formula for and method of calculating the Underlier last in effect prior to the failure, but using only those securities that comprised the Underlier immediately prior to that failure; provided that, if a Market Disruption Event occurs or is continuing on such day, then the provisions set forth below under “Market Disruption Events” shall apply in lieu of the foregoing.

Market Disruption Events

A “Market Disruption Event” means any of the following events as determined by the Calculation Agent in its sole discretion:

For purposes of determining whether a Market Disruption Event has occurred:

If a Market Disruption Event occurs or is continuing on the Determination Date, then the Determination Date will be postponed to the first succeeding Trading Day on which a Market Disruption Event has not occurred and is not continuing; however, if such first succeeding Trading Day has not occurred as of the eighth Trading Day after the originally scheduled Determination Date, that eighth Trading Day shall be deemed to be the Determination Date. If

the Determination Date has been postponed eight Trading Days after the originally scheduled Determination Date and a Market Disruption Event occurs or is continuing on such eighth Trading Day, the Calculation Agent will determine the Closing Level of the Underlier on such eighth Trading Day in accordance with the formula for and method of calculating the Closing Level of the Underlier last in effect prior to commencement of the Market Disruption Event, using the closing price (or, with respect to any relevant security, if a Market Disruption Event has occurred with respect to such security, its good faith estimate of the value of such security at the Scheduled Closing Time of the Relevant Stock Exchange for such security or, if earlier, the actual closing time of the regular trading session of such Relevant Stock Exchange) on such date of each security included in the Underlier. As used herein, “closing price” means, with respect to any security on any date, the Relevant Stock Exchange traded or quoted price of such security as of the Scheduled Closing Time of the Relevant Stock Exchange for such security or, if earlier, the actual closing time of the regular trading session of such Relevant Stock Exchange.

Calculation Agent

The Calculation Agent will determine the Cash Settlement Amount and the Final Underlier Level. In addition, the Calculation Agent will (i) determine if adjustments are required to the Closing Level of the Underlier under the circumstances described in this Security, (ii) if publication of the Underlier is discontinued, select a Successor Underlier or, if no Successor Underlier is available, determine the Closing Level of the Underlier under the circumstances described in this Security, and (iii) determine whether a Market Disruption Event or non-Trading Day has occurred.

The Company covenants that, so long as this Security is Outstanding, there shall at all times be a Calculation Agent (which shall be a broker-dealer, bank or other financial institution) with respect to this Security.

All determinations made by the Calculation Agent with respect to this Security will be at the sole discretion of the Calculation Agent and, in the absence of manifest error, will be conclusive for all purposes and binding on the Company and the Holder of this Security.

Tax Considerations

The Company agrees, and by acceptance of a beneficial ownership interest in this Security each Holder of this Security will be deemed to have agreed (in the absence of a statutory, regulatory, administrative or judicial ruling to the contrary), for United States federal income tax purposes to characterize and treat this Security as a prepaid derivative contract that is an “open transaction.”

Redemption and Repayment

This Security is not subject to redemption at the option of the Company or repayment at the option of the Holder hereof prior to March 9, 2022. This Security is not entitled to any sinking fund.

Acceleration

If an Event of Default, as defined in the Indenture, with respect to this Security shall occur and be continuing, the Cash Settlement Amount (calculated as set forth in the next sentence) of this Security may be declared due and payable in the manner and with the effect provided in the Indenture. The amount payable to the Holder hereof upon any acceleration permitted under the Indenture will be equal to the Cash Settlement Amount hereof calculated as provided herein as though the date of acceleration was the Determination Date.

__________________

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 or its duly authorized agent under the Indenture 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.

WELLS FARGO FINANCE LLC, a limited liability company duly organized and existing under the laws of the State of Delaware (hereinafter called the “Company,” which term includes any successor corporation under and as defined in the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & Co., or registered assigns, an amount equal to the Maturity Payment Amount (as defined below) on the Stated Maturity Date (as defined below), unless this Security is redeemed prior to the Stated Maturity Date as provided below under “Optional Redemption,” and to pay Contingent Coupon Payments (as defined below) on the Face Amount of this Security to the extent provided herein on the Contingent Coupon Payment Dates specified herein at the Contingent Coupon Rate (as defined below) until the earlier of the Stated Maturity Date and the Optional Redemption Date (as defined below), if any. The “Initial Stated Maturity Date” shall be March 7, 2030.

Optional Redemption

The Company may, at its option, redeem this Security, in whole but not in part, on any Optional Redemption Date (as defined below) by giving notice to the Holder hereof on or before the

Calculation Day (as defined below) immediately preceding that Optional Redemption Date. If this Security is redeemed, the Holder hereof will receive the Optional Redemption Price (as defined below) plus a final Contingent Coupon Payment (as defined below), if any, on the applicable Optional Redemption Date. Unless the Company defaults in the payment of the Optional Redemption Price plus the final Contingent Coupon Payment, if any, this Security will cease to be outstanding on such Optional Redemption Date, no additional Contingent Coupon Payments will be payable on this Security and the Holder hereof will have no further rights under this Security after such Optional Redemption Date. The “Optional Redemption Price” is equal to the Face Amount of this Security. The “Optional Redemption Dates” shall be the Contingent Coupon Payment Dates (as defined below) following each Calculation Day scheduled to occur from September 2020 to December 2029, inclusive.

Payment of Contingent Coupon Payments, the Maturity Payment Amount and the Optional Redemption Price

scheduled Calculation Day, that eighth Trading Day shall be deemed to be the Calculation Day for such Index. If a Calculation Day has been postponed eight Trading Days for an Index after the originally scheduled Calculation Day and a Market Disruption Event occurs or is continuing with respect to such Index on such eighth Trading Day, the Calculation Agent will determine the Closing Level of such Index on such eighth Trading Day in accordance with the formula for and method of calculating the Closing Level of such Index last in effect prior to commencement of the Market Disruption Event, using the closing price (or, with respect to any relevant security, if a Market Disruption Event has occurred with respect to such security, its good faith estimate of the value of such security at (i) with respect to the S&P 500 Index or the Russell 2000 Index, the Scheduled Closing Time of the Relevant Stock Exchange for such security or, if earlier, the actual closing time of the regular trading session of such Relevant Stock Exchange or (ii) with respect to the EURO STOXX 50 Index, the time at which the official Closing Level of such Index is calculated and published by the relevant Index Sponsor) on such date of each security included in such Index. As used herein, “closing price” means, with respect to any security on any date, the Relevant Stock Exchange traded or quoted price of such security as of (i) with respect to the S&P 500 Index or the Russell 2000 Index, the Scheduled Closing Time of the Relevant Stock Exchange for such security or, if earlier, the actual closing time of the regular trading session of such Relevant Stock Exchange or (ii) with respect to the EURO STOXX 50 Index, the time at which the official Closing Level of such Index is calculated and published by the relevant Index Sponsor. Notwithstanding the postponement of a Calculation Day for an Index due to a Market Disruption Event with respect to such Index on such Calculation Day, the originally scheduled Calculation Day will remain the Calculation Day for any Index not affected by a Market Disruption Event on such day.

“Calculation Agent Agreement” shall mean the Calculation Agent Agreement dated as of May 18, 2018 between the Company and the Calculation Agent, as amended from time to time.

“Calculation Agent” shall mean the Person that has entered into the Calculation Agent Agreement with the Company providing for, among other things, whether a Contingent Coupon Payment will be made, the Optional Redemption Price, if any, and the Maturity Payment Amount, if any, which term shall, unless the context otherwise requires, include its successors under such Calculation Agent Agreement. The initial Calculation Agent shall be Wells Fargo Securities, LLC. Pursuant to the Calculation Agent Agreement, the Company may appoint a different Calculation Agent from time to time after the initial issuance of this Security without the consent of the Holder of this Security and without notifying the Holder of this Security.

Certain Definitions

A “Trading Day” with respect to the Russell 2000 Index, the S&P 500 Index or the Dow Jones Industrial Average means a day, as determined by the Calculation Agent, on which (i) the Relevant Stock Exchanges with respect to each security underlying such Index are scheduled to be open for trading for their respective regular trading sessions and (ii) each Related Futures or Options Exchange with respect to such Index is scheduled to be open for trading for its regular trading session.

A “Trading Day” with respect to the EURO STOXX 50 Index means a day, as determined by the Calculation Agent, on which (i) the relevant Index Sponsor is scheduled to publish the level

of the EURO STOXX 50 Index and (ii) each Related Futures or Options Exchange with respect to the EURO STOXX 50 Index is scheduled to be open for trading for its regular trading session.

The “Relevant Stock Exchange” for any security underlying an Index means the primary exchange or quotation system on which such security is traded, as determined by the Calculation Agent.

The “Related Futures or Options Exchange” for an Index means an exchange or quotation system where trading has a material effect (as determined by the Calculation Agent) on the overall market for futures or options contracts relating to such Index.

Adjustments to an Index

If at any time the method of calculating an Index or a Successor Equity Index, or the closing level thereof, is changed in a material respect, or if an Index or a Successor Equity Index is in any other way modified so that such index does not, in the opinion of the Calculation Agent, fairly represent the level of such index had those changes or modifications not been made, then the Calculation Agent will, at the close of business in New York, New York, on each date that the closing level of such index is to be calculated, make such calculations and adjustments as, in the good faith judgment of the Calculation Agent, may be necessary in order to arrive at a level of an index comparable to such Index or Successor Equity Index as if those changes or modifications had not been made, and the Calculation Agent will calculate the closing level of such Index or Successor Equity Index with reference to such index, as so adjusted. Accordingly, if the method of calculating an Index or Successor Equity Index is modified so that the level of such index is a fraction or a multiple of what it would have been if it had not been modified (e.g., due to a split or reverse split in such equity index), then the Calculation Agent will adjust such Index or Successor Equity Index in order to arrive at a level of such index as if it had not been modified (e.g., as if the split or reverse split had not occurred).

Discontinuance of an Index

If an Index Sponsor discontinues publication of an Index, and such Index Sponsor or another entity publishes a successor or substitute equity index that the Calculation Agent determines, in its sole discretion, to be comparable to such Index (a “Successor Equity Index”), then, upon the Calculation Agent’s notification of that determination to the Trustee and the Company, the Calculation Agent will substitute the Successor Equity Index as calculated by the relevant Index Sponsor or any other entity for purposes of calculating the Closing Level of such Index on any date of determination. Upon any selection by the Calculation Agent of a Successor Equity Index, the Company will cause notice to be given to the Holder of this Security.

In the event that an Index Sponsor discontinues publication of an Index prior to, and the discontinuance is continuing on, a Calculation Day and the Calculation Agent determines that no Successor Equity Index is available at such time, the Calculation Agent will calculate a substitute Closing Level for such Index in accordance with the formula for and method of calculating such Index last in effect prior to the discontinuance, but using only those securities that comprised such Index immediately prior to that discontinuance. If a Successor Equity Index is selected or the Calculation Agent calculates a level as a substitute for such Index, the Successor Equity Index or

level will be used as a substitute for such Index for all purposes, including the purpose of determining whether a Market Disruption Event exists.

If on a Calculation Day an Index Sponsor fails to calculate and announce the level of an Index, the Calculation Agent will calculate a substitute Closing Level of such Index in accordance with the formula for and method of calculating such Index last in effect prior to the failure, but using only those securities that comprised such Index immediately prior to that failure; provided that, if a Market Disruption Event occurs or is continuing on such day with respect to such Index, then the provisions set forth above under the definition of “Calculation Days” shall apply in lieu of the foregoing.

Market Disruption Events

A “Market Disruption Event” with respect to the Russell 2000 Index, the S&P 500 Index or the Dow Jones Industrial Average means any of the following events as determined by the Calculation Agent in its sole discretion:

For purposes of determining whether a Market Disruption Event has occurred with respect to the Russell 2000 Index, the S&P 500 Index or the Dow Jones Industrial Average:

A “Market Disruption Event” with respect to the EURO STOXX 50 Index means any of (A), (B), (C) or (D) below, as determined by the Calculation Agent in its sole discretion:

For purposes of determining whether a Market Disruption Event has occurred with respect to the EURO STOXX 50 Index:

Calculation Agent

The Calculation Agent will determine whether a Contingent Coupon Payment will be made, the Optional Redemption Price, if any, and the Maturity Payment Amount, if any. In addition, the Calculation Agent will (i) determine if adjustments are required to the Closing Level of an Index under the circumstances described in this Security, (ii) if publication of an Index is discontinued, select a Successor Equity Index or, if no Successor Equity Index is available, determine the Closing Level of such Index under the circumstances described in this Security, and (iii) determine whether a Market Disruption Event has occurred.

The Company covenants that, so long as this Security is Outstanding, there shall at all times be a Calculation Agent (which shall be a broker-dealer, bank or other financial institution) with respect to this Security.

All determinations made by the Calculation Agent with respect to this Security will be at the sole discretion of the Calculation Agent and, in the absence of manifest error, will be conclusive for all purposes and binding on the Company and the Holder of this Security.

Redemption and Repayment

This Security is not subject to repayment at the option of the Holder hereof prior to March 7, 2030. This Security is subject to redemption prior to March 7, 2030 as set forth under “Optional Redemption” above. This Security is not entitled to any sinking fund.

Acceleration

If an Event of Default, as defined in the Indenture, with respect to this Security shall occur and be continuing, the Maturity Payment Amount (calculated as set forth in the next two sentences) of this Security may be declared due and payable in the manner and with the effect provided in the Indenture. The amount payable to the Holder hereof upon any acceleration permitted under the Indenture will be equal to the Maturity Payment Amount hereof calculated as provided herein, plus a portion of a final Contingent Coupon Payment, if any.

Fully and Unconditionally Guaranteed by Wells Fargo & Company

Principal at Risk Securities Linked to the Lowest Performing of the Dow Jones Industrial Average^®, the Russell 2000^® Index and the Nasdaq-100 Index^® due March 7, 2025

WELLS FARGO FINANCE LLC, a limited liability company duly organized and existing under the laws of the State of Delaware (hereinafter called the “Company,” which term includes any successor corporation under and as defined in the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & Co., or registered assigns, an amount equal to the Maturity Payment Amount (as defined below) on the Stated Maturity Date (as defined below), unless this Security is redeemed prior to the Stated Maturity Date as provided below under “Optional Redemption,” and to pay Contingent Coupon Payments (as defined below) on the Face Amount of this Security to the extent provided herein on the Contingent Coupon Payment Dates specified herein at the Contingent Coupon Rate (as defined below) until the earlier of the Stated Maturity Date and the Optional Redemption Date (as defined below), if any. The “Initial Stated Maturity Date” shall be March 7, 2025. If the Final Calculation Day (as defined below) is not postponed, the Initial Stated Maturity Date will be the “Stated Maturity Date.” If the Final Calculation Day is postponed, the “Stated Maturity Date” shall be the later of (i) the Initial Stated Maturity Date and (ii) three Business Days (as defined below) after the last Final Calculation Day as postponed.

“Face Amount” shall mean, when used with respect to this Security, the amount set forth on the face of this Security as its “Face Amount.”

Optional Redemption

The Company may, at its option, redeem this Security, in whole but not in part, on any Optional Redemption Date (as defined below) by giving notice to the Holder hereof on or before the Calculation Day (as defined below) immediately preceding that Optional Redemption Date. If this

Security is redeemed, the Holder hereof will receive the Optional Redemption Price (as defined below) plus a final Contingent Coupon Payment (as defined below), if any, on the applicable Optional Redemption Date. Unless the Company defaults in the payment of the Optional Redemption Price plus the final Contingent Coupon Payment, if any, this Security will cease to be outstanding on such Optional Redemption Date, no additional Contingent Coupon Payments will be payable on this Security and the Holder hereof will have no further rights under this Security after such Optional Redemption Date. The “Optional Redemption Price” is equal to the Face Amount of this Security. The “Optional Redemption Dates” shall be the Contingent Coupon Payment Dates (as defined below) following each Calculation Day scheduled to occur from September 2020 to December 2024, inclusive.

Payment of Contingent Coupon Payments, the Maturity Payment Amount and the Optional Redemption Price

On each quarterly Contingent Coupon Payment Date, the Company shall pay a Contingent Coupon Payment if, and only if, the Closing Level (as defined below) of the Lowest Performing Index (as defined below) on the related Calculation Day is greater than or equal to its Coupon Threshold Level (as defined below). A “Contingent Coupon Payment,” if payable as provided herein, shall be equal to (i) the product of the Face Amount of this Security and the Contingent Coupon Rate, (ii) divided by 4. The “Contingent Coupon Payment Dates” shall be the third Business Day following each Calculation Day, as each such Calculation Day may be postponed as herein provided, provided that the Contingent Coupon Payment Date with respect to the Final Calculation Day will be the Stated Maturity Date. If a Calculation Day is postponed with respect to one or more Indices, the related Contingent Coupon Payment Date will be three Business Days after the last Calculation Day as postponed. The “Contingent Coupon Rate” is 9.25% per annum. Any Contingent Coupon Payments will be rounded to the nearest cent, with one-half cent rounded upward. If a Contingent Coupon Payment Date is postponed, the Contingent Coupon Payment, if any, due on that Contingent Coupon Payment Date will be made on that Contingent Coupon Payment Date as so postponed with the same force and effect as if it had been made on the originally scheduled Contingent Coupon Payment Date, with no additional amount accruing or payable as a result of the postponement.

Any Contingent Coupon Payment so payable, and punctually paid or duly provided for, on any Contingent Coupon Payment Date will, as provided in the Indenture, 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 for such Contingent Coupon Payment next preceding such Contingent Coupon Payment Date. The Regular Record Date for a Contingent Coupon Payment Date shall be the date one Business Day prior to such Contingent Coupon Payment Date.

Any Contingent Coupon Payment not punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Securities of this series not less than 10 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 the Indenture.

Payment of any Contingent Coupon Payment on this Security will be made in immediately available funds at the office or agency of the Company maintained for that purpose in the City of Minneapolis, Minnesota; provided, however, that, at the option of the Company, payment of any Contingent Coupon Payment may be paid by check mailed to the Person entitled thereto at such Person’s last address as it appears in the Security Register or by wire transfer to such account as may have been designated by such Person. Payments of any Contingent Coupon Payment and the Maturity Payment Amount or the Optional Redemption Price, as applicable, on this Security at Maturity will be made against presentation of this Security at the office or agency of the Company maintained for that purpose in the City of Minneapolis, Minnesota and at any other office or agency maintained by the Company for such purpose. Notwithstanding the foregoing, for so long as this Security is a Global Security registered in the name of the Depositary, any payments on this Security will be made to the Depositary by wire transfer of immediately available funds.

Payment of the Maturity Payment Amount or the Optional Redemption Price, as applicable, and any Contingent Coupon Payments on this Security will be made in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

Definitions Relating to Maturity Payment Amount, the Optional Redemption Price and Contingent Coupon Payments

If this Security is not redeemed prior to the Stated Maturity Date as provided above under “Optional Redemption,” the “Maturity Payment Amount” of this Security will equal:

All calculations with respect to the Maturity Payment Amount will be rounded to the nearest one hundred-thousandth, with five one-millionths rounded upward (e.g., 0.000005 would be rounded to 0.00001); and the Maturity Payment Amount will be rounded to the nearest cent, with one-half cent rounded upward.

“Index” shall mean each of the Dow Jones Industrial Average, the Russell 2000 Index and the Nasdaq-100 Index.

The “Pricing Date” shall mean March 4, 2020.

The “Lowest Performing Index” for any Calculation Day will be the Index with the lowest Performance Factor on that Calculation Day (as such Calculation Day may be postponed for one or more Indices).

The “Performance Factor” with respect to an Index on any Calculation Day is its Closing Level on such Calculation Day divided by its Starting Level (expressed as a percentage).

The “Starting Level” with respect to the Dow Jones Industrial Average is 27090.86, its Closing Level on the Pricing Date, with respect to the Russell 2000 Index is 1531.197, its Closing Level on the Pricing Date, and with respect to the Nasdaq-100 Index is 8949.28, its Closing Level on the Pricing Date.

The “Ending Level” of an Index will be its Closing Level on the Final Calculation Day.

The “Coupon Threshold Level” with respect to the Dow Jones Industrial Average is 18963.602, which is equal to 70% of its Starting Level, with respect to the Russell 2000 Index is 1071.8379, which is equal to 70% of its Starting Level, and with respect to the Nasdaq-100 Index is 6264.496, which is equal to 70% of its Starting Level.

If any such day is not a Trading Day with respect to any Index, such Calculation Day for each Index will be postponed to the next succeeding day that is a Trading Day with respect to each Index. A Calculation Day for an Index is also subject to postponement due to the occurrence of a Market Disruption Event (as defined below) with respect to such Index on such Calculation Day. The “Final Calculation Day” is March 4, 2025. If a Market Disruption Event occurs or is continuing with respect to an Index on any Calculation Day, then such Calculation Day for such Index will be postponed to the first succeeding Trading Day for such Index on which a Market Disruption Event for such Index has not occurred and is not continuing; however, if such first

succeeding Trading Day has not occurred as of the eighth Trading Day for such Index after the originally scheduled Calculation Day, that eighth Trading Day shall be deemed to be the Calculation Day for such Index. If a Calculation Day has been postponed eight Trading Days for an Index after the originally scheduled Calculation Day and a Market Disruption Event occurs or is continuing with respect to such Index on such eighth Trading Day, the Calculation Agent will determine the Closing Level of such Index on such eighth Trading Day in accordance with the formula for and method of calculating the Closing Level of such Index last in effect prior to commencement of the Market Disruption Event, using the closing price (or, with respect to any relevant security, if a Market Disruption Event has occurred with respect to such security, its good faith estimate of the value of such security at the Scheduled Closing Time of the Relevant Stock Exchange for such security or, if earlier, the actual closing time of the regular trading session of such Relevant Stock Exchange) on that day of each security included in such Index. As used herein, “closing price” means, with respect to any security on any date, the Relevant Stock Exchange traded or quoted price of such security as of the Scheduled Closing Time of the Relevant Stock Exchange for such security or, if earlier, the actual closing time of the regular trading session of such Relevant Stock Exchange. Notwithstanding the postponement of a Calculation Day for an Index due to a Market Disruption Event with respect to such Index on such Calculation Day, the originally scheduled Calculation Day will remain the Calculation Day for any Index not affected by a Market Disruption Event on such day.

“Calculation Agent Agreement” shall mean the Calculation Agent Agreement dated as of May 18, 2018 between the Company and the Calculation Agent, as amended from time to time.

“Calculation Agent” shall mean the Person that has entered into the Calculation Agent Agreement with the Company providing for, among other things, whether a Contingent Coupon Payment will be made, the Optional Redemption Price, if any, and the Maturity Payment Amount, if any, which term shall, unless the context otherwise requires, include its successors under such Calculation Agent Agreement.

Adjustments to an Index

If at any time the method of calculating an Index or a Successor Equity Index, or the closing level thereof, is changed in a material respect, or if an Index or a Successor Equity Index is in any other way modified so that such index does not, in the opinion of the Calculation Agent, fairly represent the level of such index had those changes or modifications not been made, then the Calculation Agent will, at the close of business in New York, New York, on each date that the closing level of such index is to be calculated, make such calculations and adjustments as, in the good faith judgment of the Calculation Agent, may be necessary in order to arrive at a level of an index comparable to such Index or Successor Equity Index as if those changes or modifications had not been made, and the Calculation Agent will calculate the closing level of such Index or Successor Equity Index with reference to such index, as so adjusted. Accordingly, if the method of calculating an Index or Successor Equity Index is modified so that the level of such index is a fraction or a multiple of what it would have been if it had not been modified (e.g., due to a split or reverse split in such equity index), then the Calculation Agent will adjust such Index or Successor Equity Index in order to arrive at a level of such index as if it had not been modified (e.g., as if the split or reverse split had not occurred).

Discontinuance of an Index

If an Index Sponsor discontinues publication of an Index, and such Index Sponsor or another entity publishes a successor or substitute equity index that the Calculation Agent determines, in its sole discretion, to be comparable to such Index (a “Successor Equity Index”), then, upon the Calculation Agent’s notification of that determination to the Trustee and the Company, the Calculation Agent will substitute the Successor Equity Index as calculated by the relevant Index Sponsor or any other entity for purposes of calculating the Closing Level of such Index on any date of determination. Upon any selection by the Calculation Agent of a Successor Equity Index, the Company will cause notice to be given to the Holder of this Security.

In the event that an Index Sponsor discontinues publication of an Index prior to, and the discontinuance is continuing on, a Calculation Day and the Calculation Agent determines that no Successor Equity Index is available at such time, the Calculation Agent will calculate a substitute Closing Level for such Index in accordance with the formula for and method of calculating such Index last in effect prior to the discontinuance, but using only those securities that comprised such Index immediately prior to that discontinuance. If a Successor Equity Index is selected or the Calculation Agent calculates a level as a substitute for such Index, the Successor Equity Index or level will be used as a substitute for such Index for all purposes, including the purpose of determining whether a Market Disruption Event exists.

If on a Calculation Day an Index Sponsor fails to calculate and announce the level of an Index, the Calculation Agent will calculate a substitute Closing Level of such Index in accordance with the formula for and method of calculating such Index last in effect prior to the failure, but using only those securities that comprised such Index immediately prior to that failure; provided that, if a Market Disruption Event occurs or is continuing on such day with respect to such Index, then the provisions set forth above under the definition of “Calculation Days” shall apply in lieu of the foregoing.

Market Disruption Events

A “Market Disruption Event” with respect to an Index means any of the following events as determined by the Calculation Agent in its sole discretion:

For purposes of determining whether a Market Disruption Event has occurred with respect to an Index:

Calculation Agent

The Calculation Agent will determine whether a Contingent Coupon Payment will be made, the Optional Redemption Price, if any, and the Maturity Payment Amount, if any. In addition, the

Calculation Agent will (i) determine if adjustments are required to the Closing Level of an Index under the circumstances described in this Security, (ii) if publication of an Index is discontinued, select a Successor Equity Index or, if no Successor Equity Index is available, determine the Closing Level of such Index under the circumstances described in this Security, and (iii) determine whether a Market Disruption Event has occurred.

The Company covenants that, so long as this Security is Outstanding, there shall at all times be a Calculation Agent (which shall be a broker-dealer, bank or other financial institution) with respect to this Security.

All determinations made by the Calculation Agent with respect to this Security will be at the sole discretion of the Calculation Agent and, in the absence of manifest error, will be conclusive for all purposes and binding on the Company and the Holder of this Security.

Redemption and Repayment

This Security is not subject to repayment at the option of the Holder hereof prior to March 7, 2025. This Security is subject to redemption prior to March 7, 2025 as set forth under “Optional Redemption” above. This Security is not entitled to any sinking fund.

Acceleration

If an Event of Default, as defined in the Indenture, with respect to this Security shall occur and be continuing, the Maturity Payment Amount (calculated as set forth in the next two sentences) of this Security may be declared due and payable in the manner and with the effect provided in the Indenture. The amount payable to the Holder hereof upon any acceleration permitted under the Indenture will be equal to the Maturity Payment Amount hereof calculated as provided herein, plus a portion of a final Contingent Coupon Payment, if any. The Maturity Payment Amount and any final Contingent Coupon Payment will be calculated as though the date of acceleration were the Final Calculation Day. The final Contingent Coupon Payment, if any, will be prorated from and including the immediately preceding Contingent Coupon Payment Date to but excluding the date of acceleration.
