Maturity date: Unless earlier redeemed by us, July 30, 2026
Contingent coupon: On each quarterly contingent coupon payment date, unless previously redeemed by us, the securities will pay a contingent coupon equal to 2.45% of the stated principal amount of the securities (9.80% per annum) if and only if a coupon barrier event has not occurred during the related observation period. If a coupon barrier event occurs during an observation period, you will not receive any contingent coupon payment on the related contingent coupon payment date. A coupon barrier event will occur if the closing level of any underlying index is less than its coupon barrier level on any trading day for that underlying index during an observation period.
Payment at maturity1:

Unless earlier redeemed by us, for each $1,000 stated principal amount security you hold at maturity, you will receive cash in an amount determined as follows (in addition to the final contingent coupon payment, if any):

·     If the final index level of the worst performing underlying index is greater than or equal to its downside threshold level: $1,000

·     If the final index level of the worst performing underlying index is less than its downside threshold level:

$1,000 + ($1,000 × the index return of the worst performing underlying index

If the final index level of the worst performing underlying index is less than its downside threshold level, you will receive less, and possibly significantly less, than 70.00% of the stated principal amount of your securities at maturity.

Coupon barrier event: A coupon barrier event will occur with respect to an observation period if the closing level of any underlying index is less than its coupon barrier level on any trading day for that underlying index during that observation period.
Observation periods: Each observation period will consist of each day from but excluding an observation period end-date to and including the following observation period end-date, provided that the first observation period will consist of each day from but excluding the pricing date to and including the first observation period end-date.
Trading day: For any underlying index, a scheduled trading day for that underlying index on which a market disruption event has not occurred with respect to that underlying index.
