Terms of the Notes

The Contingent Income Auto-Callable Yield Notes Linked to the Least Performing of the Dow Jones Industrial Average^®, the Nasdaq-100^® Index and the Russell 2000^® Index (the “Notes”) provide a quarterly Contingent Coupon Payment of $13.75 on the applicable Contingent Payment Date if, on any quarterly Observation Date, the Observation Value of each Underlying is greater than or equal to its Coupon Barrier. Beginning in April 2022, if the Observation Value of each Underlying is greater than or equal to 100% of its Starting Value on any applicable quarterly Observation Date (other than the final Observation Date), the Notes will be automatically called, in whole but not in part, at an amount equal to 100% of the principal amount, together with the relevant Contingent Coupon Payment. No further amounts will be payable following an Automatic Call. If the Notes are not automatically called, at maturity you will receive the Redemption Amount, calculated as described under “Redemption Amount Determination”.

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 Contingent Coupon Payment, Early Redemption Amount or Redemption Amount, as applicable, will not reflect the levels of the Underlyings other than on the Observation Dates.

· 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 and the Notes do not provide for any regular fixed coupon payments.

· Because the Notes are linked to the least performing (and not the average performance) of the Underlyings, you may not receive any return on the Notes and may lose some or all of your principal amount even if the Observation Value of one Underlying is always greater than or equal to its Coupon Barrier or Threshold Value, as applicable.

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

· Any payment on the Notes is 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 Notes are subject to risks associated with small-size capitalization companies.

· The Notes are subject to risks associated with foreign securities markets.
