(1) The “Return on the Notes” is calculated based on the Redemption Amount and potential final Contingent Coupon Payment, not including any Contingent Coupon Payments paid prior to maturity, and assumes that the relevant Contingent Coupon Payment has been made on each prior Contingent Payment Date. (2) This amount represents the sum of the principal amount and the final Contingent Coupon Payment(assuming that each prior monthly Contingent Coupon Payment has been made on the related Contingent Payment Date). (3) This is the Underlying Stock Return which corresponds to the Coupon Barrier and the Threshold Value of the Underlying Stock.

Risk Factors

Your investment may result in a loss; there is no guaranteed return of principal.

Your return on the Notes is limited to the return represented by the Contingent Coupon Payments, if any, over the term of the Notes.

The Notes are subject to a potential Automatic Call, which would limit your ability to receive the Contingent Coupon Payments over the full term of the Notes.

You may not receive any Contingent Coupon Payments.

Your return on the Notes may be less than the yield on a conventional debt security of comparable maturity.

The Contingent Coupon Payment, Early Redemption Amount or Redemption Amount, as applicable, will not reflect changes in the price of the Underlying Stock other than on the Observation Dates or Call Observation Dates, as applicable.

Any payments on the Notes are subject to our credit risk and the credit risk of the Guarantor, and any actual or perceived changes in our or the Guarantor’s creditworthiness are expected to affect the value of the Notes.

The public offering price you pay for the Notes will exceed their initial estimated value.

We cannot assure you that a trading market for your Notes will ever develop or be maintained.

The terms of the Notes will not be adjusted for all corporate events that could affect the issuer of the Underlying Stock.

You may revoke your offer to purchase the Notes at any time prior to the time at which we accept such offer on the date the Notes are priced. We reserve the right to change the terms of, or reject any offer to purchase, the Notes prior to their issuance. In the event of any changes to the terms of the Notes, we will notify you and you will be asked to accept such changes in connection with your purchase. You may also choose to reject such changes in which case we may reject your offer to purchase.
