Hypothetical Amounts Payable at Maturity

The examples below show hypothetical amounts you could receive at maturity on the Notes for a range of Ending Values of the Underlying Equity. The examples of hypothetical amounts you could receive at maturity set forth below are intended to illustrate the effect of different Ending Values of the Underlying Equity on the amount you could receive on the Notes at maturity. All of the hypothetical examples are based on the following assumptions:

 

O      Issue Price:  $10.00 per Note

O      Maximum Return:  25.00% (20.00% per annum on a simple interest basis)

O      Starting Value:  125

  

O      Annualized dividend yield of the Underlying Equity:  1.25%

O      Maturity:  1.25 years

O      Upside Participation Rate:  300%

The following examples are for purposes of illustration only. The actual amount you receive at maturity will depend on the actual Return Amount, which, in turn, will depend on the actual Starting Value, Ending Value and maximum return.
