Hypothetical Payout Profile (maturity payment amount)*

* If the ending price is less than the threshold price, you will receive on the stated maturity date per security a number of shares of the Underlying Stock equal to the share delivery amount. Fractional shares will be paid in cash. In addition, if, due to an event beyond our control, we determine it is impossible, impracticable (including unduly burdensome) or illegal for us to deliver shares of the Underlying Stock to you at maturity, we will pay the cash equivalent of the share delivery amount (as determined by the calculation agent in good faith and in a commercially reasonable manner) in lieu of delivering shares. For purposes of the above profile, the value of the shares received is calculated based on the ending price. The actual value of any shares received on the stated maturity date will depend on the price of the Underlying Stock on the stated maturity date , which may be less than the ending price.

If the securities are not automatically called prior to stated maturity and the ending price is less than the threshold price, you will receive at maturity a number of shares of the Underlying Stock that will likely be worth less than the principal amount of your securities and could be worth nothing. The actual value of the shares you receive at maturity will depend on the price of the Underlying Stock on the stated maturity date, which may be lower than the ending price.

Any return on the securities will be limited to the sum of your contingent coupon payments, if any. You will not participate in any appreciation of the Underlying Stock, but you will have downside exposure to the Underlying Stock if the ending price is less than the threshold price.
