Determination of Maturity Payment Amount and Certain Definitions

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

All calculations with respect to any payments on this Security (whether upon optional redemption, automatic call or at stated maturity) 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 such payment will be rounded to the nearest cent, with one-half cent rounded upward. Payment of the Optional Redemption Price, the Automatic Call Price or the Maturity Payment Amount, as applicable, will be made in such coin or currency of the United States of America as at the time is legal tender for payment of public and private debts.

“Index” shall mean each of the S&P 500 Index and the Russell 2000 Index.

The “Pricing Date” shall mean January 17, 2019.

The “Lowest Performing Index” on the Automatic Call Date and the Final Calculation Day will be the Index with the lowest Performance Factor on that date (as such date may be postponed for one or both Indices pursuant to “Calculation Days” below, if applicable).

The “Performance Factor” with respect to an Index on the Automatic Call Date and the Final Calculation Day, is its Closing Level on such date divided by its Starting Level (expressed as a percentage).

The “Maturity Date Premium” shall be 15.15% of the Face Amount of this Security.

The “Contingent Fixed Return” shall be 9.00% of the Face Amount of this Security.

The “Closing Level” with respect to each Index on any Trading Day means the official closing level of that Index reported by the relevant Index Sponsor on such Trading Day, as obtained by the Calculation Agent on such Trading Day from the licensed third-party market data vendor contracted by the Calculation Agent at such time; in particular, taking into account the decimal precision and/or rounding convention employed by such licensed third-party market data vendor on such date, subject to the provisions set forth below under “—Market Disruption Events,” “—Adjustments to an Index” and “—Discontinuance of an Index.”

The “Starting Level” with respect to the S&P 500 Index is 2616.10, its Closing Level on January 16, 2019, and with respect to the Russell 2000 Index is 1454.697, its Closing Level on January 16, 2019.

“Index Sponsor” shall mean the sponsor or publisher of an Index.

The “Calculation Days” shall be each of the Redemption Notice Date, the Automatic Call Date and the Final Calculation Day. If any Calculation Day is not a Trading Day with respect to either 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. 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 one 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 the other Index if such other Index is not affected by a Market Disruption Event on such day.

The “Final Calculation Day” is July 17, 2020, subject to postponement with respect to one or both Indices as described above under “Calculation Days”.

“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, the determination of whether this Security will be automatically called on the Automatic Call Date, the Automatic Call Price, if any, and the Maturity Payment Amount, 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.

A “Trading Day” with respect to an Index 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.

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 an Index means any of the following events as determined by the Calculation Agent in its sole discretion:

Exchange at any time during the one-hour period that ends at the Close of Trading on that day.

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

Related Futures or Options Exchange on such Trading Day, without regard to after hours or any other trading outside the regular trading session hours; and

Calculation Agent

The Calculation Agent will determine whether this Security will be automatically called on the Automatic Call Date, the Automatic Call Price, if any, and the Maturity Payment Amount. In addition, the Calculation Agent will (i) determine if adjustments are required to the Closing Levels of the Indices 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 that 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.

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 treat this Security as a prepaid derivative contract that is an “open transaction.”

Redemption and Repayment

This Security is not subject to repayment at the option of the Holder hereof prior to July 22, 2020. This Security is subject to redemption prior to July 22, 2020 as set forth under “Optional Redemption” above and is subject to an automatic call prior to July 22, 2020 as set forth under “Automatic Call” 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 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 Maturity Payment Amount, calculated as provided herein as though the date of acceleration was the Final Calculation Day; provided that if the Closing Level of the Lowest Performing Index on the date of acceleration is equal to or greater than its Starting Level, then the Maturity Payment Amount will be calculated using a Maturity Date Premium that is prorated to the date of acceleration.

__________________

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.
