Maturity date:	Unless earlier automatically redeemed, October 17, 2024
Contingent coupon:	On each quarterly contingent coupon payment date, unless previously redeemed, the securities will pay a contingent coupon equal to 2.40% of the stated principal amount of the securities (approximately 9.60% per annum) if and only if the closing level of the underlying index on the related valuation date is greater than or equal to the downside threshold level.  If the closing level of the underlying index on any quarterly valuation date is less than the downside threshold level, you will not receive any contingent coupon payment on the related contingent coupon payment date.

Automatic early redemption:	If, on any potential redemption date, the closing level of the underlying index is greater than or equal to the initial index level, each security you then hold will be automatically redeemed on the related contingent coupon payment date for an amount in cash equal to the early redemption payment.  If the securities are redeemed, no further payments will be made.
