Hypothetical Payout Profile

The profile to the right illustrates the potential payment on the securities for a range of hypothetical percentage changes in the Closing Level of the Index from the Pricing Date to the applicable Call Observation Date (including the Final Valuation Date), assuming a Threshold Level equal to 90% of the Starting Level. The Call Premiums shown in the profile are hypothetical and are based on the midpoint of the ranges specified for the Call Premiums.

This graph has been prepared for purposes of illustration only. Your actual return will depend on (i) whether the securities are automatically called; (ii) if the securities are automatically called, the actual Call Premium and the actual Call Observation Date on which the securities are called; (iii) if the securities are not automatically called, the actual Ending Level; and (iv) whether you hold your securities to maturity or earlier automatic call.

Hypothetical Returns

If the securities are automatically called:

Hypothetical Call Observation Date on which Securities are Automatically Called	Hypothetical Payment Per Security on Related Call Payment Date*	Hypothetical Pre-Tax Total Rate of Return
1st Call Observation Date	$1,065.00	6.50%
2nd Call Observation Date	$1,130.00	13.00%
3rd Call Observation Date	$1,195.00	19.50%
4th Call Observation Date	$1,260.00	26.00%

* Assuming that the Call Premiums are equal to the midpoints of their specified ranges.

If the securities are not automatically called:

Hypothetical Ending Level	Hypothetical Percentage Change From the Hypothetical Starting Level to the Hypothetical Ending Level	Hypothetical Payment at Maturity per Security	Hypothetical Pre-Tax Total Rate of Return
99.99	-0.01%	$1,000.00	0.00%
95.00	-5.00%	$1,000.00	0.00%
90.00	-10.00%	$1,000.00	0.00%
89.00	-11.00%	$990.00	-1.00%
80.00	-20.00%	$900.00	-10.00%
75.00	-25.00%	$850.00	-15.00%
50.00	-50.00%	$600.00	-40.00%
25.00	-75.00%	$350.00	-65.00%
0.00	-100.00%	$100.00	-90.00%

Assumes a hypothetical Starting Level of 100.00. The hypothetical Starting Level of 100.00 has been chosen for illustrative purposes only and does not represent the actual Starting Level. The actual Starting Level will be determined on the Pricing Date and will be set forth under “Summary of Terms” above in the final pricing supplement. For historical data regarding the actual Closing Levels of the Index, see the historical information set forth under the section titled “The Russell 2000® Index” in the accompanying preliminary pricing supplement.

The above figures are for purposes of illustration only and may have been rounded for ease of analysis. The actual amount you receive upon an automatic call or at maturity and the resulting pre-tax rate of return will depend on (i) whether the securities are automatically called; (ii) if the securities are automatically called, the actual Call Premium and the actual Call Observation Date on which the securities are called; and (iii) if the securities are not automatically called, the actual Ending Level.

Call Observation Dates and Call Premiums

The Call Premium applicable to each Call Observation Date will be a percentage of the principal amount that increases for each Call Observation Date based on a simple (non-compounding) return of approximately 6.00% to approximately 7.00% per annum (to be determined on the Pricing Date). The actual Call Premium and payment per security upon an automatic call that is applicable to each Call Observation Date will be determined on the Pricing Date and will be within the range specified in the table below. The last Call Observation Date is the Final Valuation Date, and payment upon an automatic call on the Final Valuation Date, if applicable, will be made on the Stated Maturity Date.

Call Observation Date	Call Premium	Payment per Security upon an Automatic Call
July 22, 2021	[6.00 - 7.00%] of the principal amount	[$1,060.00 - $1,070.00]
July 22, 2022	[12.00 - 14.00%] of the principal amount	[$1,120.00 - $1,140.00]
July 24, 2023	[18.00 - 21.00%] of the principal amount	[$1,180.00 - $1,210.00]
July 17, 2024	[24.00 - 28.00%] of the principal amount	[$1,240.00 - $1,280.00]

How the Payment at Maturity Is Calculated

If the Closing Level of the Index is less than the Starting Level on each of the Call Observation Dates, the securities will not be automatically called, and on the Stated Maturity Date, you will receive a payment at maturity per security determined as follows:

·	If the Ending Level is less than the Starting Level, but greater than or equal to the Threshold Level, the payment at maturity will be equal to $1,000

·	If the Ending Level is less than the Threshold Level, the payment at maturity will be equal to $1,000 minus

Any positive return on the securities will be limited to the applicable Call Premium, even if the Closing Level of the Index significantly exceeds the Starting Level on the applicable Call Observation Date. You will not participate in any appreciation of the Index beyond the applicable Call Premium. If the securities are not automatically called prior to the Final Valuation Date and the Ending Level is less than the Threshold Level, you will receive less, and possibly 90% less, than the principal amount of your securities at maturity.
