Hypothetical Payout Profile

The profile to the right is based on a hypothetical Capped Value of 130.50% of the principal amount or $1,305.00 per $1,000 security (the midpoint of the specified range for the Capped Value), the Participation Rate of 125% and the Threshold Price equal to 90% of the Initial Price.

This graph has been prepared for purposes of illustration only. Your actual return will depend on the actual Capped Value, the actual Final Price, and whether you hold your securities to maturity.

(1) Assumes a hypothetical Capped Value of 130.50% of the principal amount, or $1,305.00 per security (the midpoint of the specified range of the Capped Value).

(2) The Initial Price.

The above figures are for purposes of illustration only and may have been rounded for ease of analysis. The actual amount you receive on the Stated Maturity Date and the resulting pre-tax rate of return will depend on the actual Capped Value and Final Price.

How the Redemption Amount Is Calculated

The Redemption Amount will be determined as follows:

· If the Final Price is greater than the Initial Price, the Redemption Amount will be equal to the lesser of:

(i) $1,000 plus

(ii) the Capped Value

· If the Final Price is less than or equal to the Initial Price, but greater than or equal to the Threshold Price, the Redemption Amount will be equal to $1,000

· If the Final Price is less than the Threshold Price, the Redemption Amount will be equal to $1,000 minus

In such a case, you will lose up to 90% of your principal amount.

How the Final Price Is Calculated

The Final Price will be calculated based on the weighted returns of the Basket Components and will be equal to the product of (i) 100 and (ii) an amount equal to 1 plus the sum of: (A) 60% of the Component Return of the EFA, and (B) 40% of the Component Return of the EEM.

The Component Return of a Basket Component will be equal to:

Final Component Price – Initial Component Price

Initial Component Price

where,

· the “Initial Component Price” will be the Fund Closing Price of such Basket Component on the Pricing Date; and

· the “Final Component Price” will be the Fund Closing Price of such Basket Component on the Final Valuation Date.
