Investors are urged to read all the risk factors related to the notes in the pricing supplement and the product supplement to which this term sheet relates. • Your return on the notes may result in a loss. • Your return on the notes is limited to the Maximum Redemption Amount, regardless of any appreciation in the levels of the Reference Asset. • Your return on the notes may be lower than the return on a conventional debt security of comparable maturity. • The notes are unsecured debt obligations of the Issuer and your investment is subject to the credit risk of the Issuer. • Our and our affiliates’ activities may conflict with your interests and may also adversely affect the value of the notes. • Our initial estimated value of the notes will be lower than the price to public, does not represent any future value of the notes, and may also differ from the estimated value of any other party. • The terms of the notes are not determined by reference to the credit spreads for our conventional fixed - rate debt. • The inclusion of the hedging profits, if any, in the initial price to public of the notes, as well as our hedging costs, is likely to adversely affect the price at which you can sell your notes. • You will not have any shareholder rights and will have no right to receive any securities represented by the Reference Asset at maturity. • No delivery of shares of the Reference Asset. • Changes that affect the Reference Asset will affect the market value of the notes and the amount you will receive at maturity.

Selected Risk Considerations:

3 Hypothetical Calculations for the Payment at Maturity: Examples of the Hypothetical Payment at Maturity for a $1,000 Investment in the notes The following table illustrates the hypothetical payments on a note at maturity. The hypothetical payments are based on a $1,000 investment in the note, a hypothetical Initial Level of $100.00, a hypothetical Upside Leverage Factor of 125.00%, the Maximum Return of 17.20%, the Maximum Redemption Amount of $1,172.00, and a range of hypothetical Final Levels and the effect on the payment at maturity. The hypothetical examples shown below are intended to help you understand the terms of the notes. The actual cash amount that you will receive at maturity will depend upon the Final Level of the Reference Asset. You may lose up to 10.00% of the principal amount at maturity. These examples do not give effect to any U.S. federal tax payments or brokerage commissions that you may be required to pay in connection with your purchase of the notes.
