Buffered Return Enhanced Notes Linked to the Dow Jones EURO STOXX 50® Index due September 9, 2008

General

Key Terms

Index:

The Dow Jones EURO STOXX 50® Index (the “Index”)

Upside Leverage Factor:

2

Payment at Maturity:

If the Ending Index Level is greater than the Initial Index Level, you will receive a cash payment that provides you with a return per $1,000 principal amount note equal to the Index Return multiplied by two, subject to a Maximum Total Return on the notes of 19.40%. For example, if the Index Return is more than 9.70%, you will receive the Maximum Total Return on the notes of 19.40%, which entitles you to a maximum payment at maturity of $1,194 for every $1,000 principal amount note that you hold. Accordingly, if the Index Return is positive, your payment per $1,000 principal amount note will be calculated as follows, subject to the Maximum Total Return:

 

$1,000 + [$1,000 x (Index Return x 2)]

 

Your principal is protected against up to a 10% decline of the Index at maturity. If the Ending Index Level declines from the Initial Index Level by up to 10%, you will receive the principal amount of your notes at maturity.

  If the Ending Index Level declines from the Initial Index Level by more than 10%, you will lose 1.1111% of the principal amount of your notes for every 1% that the Index declines beyond 10% and your final payment per $1,000 principal amount note will be calculated as follows:

 

$1,000 + [$1,000 x (Index Return + 10%) x 1.1111]

 

You will lose some or all of your investment at maturity if the Ending Index Level declines from the Initial Index Level by more than 10%.

Buffer Amount:

10%

Downside Leverage Factor:

1.1111

Index Return:

The performance of the Index from the Initial Index Level to the Ending Index Level, calculated as follows:

 
Ending Index Level – Initial Index Level
Initial Index Level

Initial Index Level:

The Index closing level on the pricing date, which was 4238.63.

Ending Index Level:

The arithmetic average of the Index closing levels on each of the five Averaging Dates.

Averaging Dates:

August 29, 2008, September 1, 2008, September 2, 2008, September 3, 2008 and September 4, 2008

Maturity Date:

September 9, 2008

Hypothetical Examples of Amounts Payable at Maturity

The following examples illustrate how the total returns set forth in the table and graph above are calculated.

Example 1: The level of the Index increases from the Initial Index Level of 4250 to an Ending Index Level of 4462.50. Because the Ending Index Level of 4462.50 is greater than the Initial Index Level of 4250 and the Index Return of 5% multiplied by 2 does not exceed the Maximum Total Return of 19.40%, the investor receives a payment at maturity of $1,100 per $1,000 principal amount note, calculated as follows:

$1,000 + [$1,000 x (5% x 2)] = $1,100

Example 2: The level of the Index decreases from the Initial Index Level of 4250 to an Ending Index Level of 3825.
Because the Ending Index Level of 3825 is less than the Initial Index Level of 4250 by not more than the Buffer Amount of 10%, the investor will receive a payment at maturity of $1,000 per $1,000 principal amount note.

Example 3: The level of the Index increases from the Initial Index Level of 4250 to an Ending Index Level of 5312.50. Because the Ending Index Level of 5312.50 is greater than the Initial Index Level of 4250 and the Index Return of 25% multiplied by 2 exceeds the Maximum Total Return of 19.40%, the investor receives a payment at maturity of $1,194 per $1,000 principal amount note, the maximum payment on the notes.

Example 4: The level of the Index decreases from the Initial Index Level of 4250 to an Ending Index Level of 3400. Because the Ending Index Level of 3400 is less than the Initial Index Level of 4250 by more than the Buffer Amount of 10%, the Index Return is negative and the investor receives a payment at maturity of $888.89 per $1,000 principal amount note, calculated as follows:

$1,000 + [$1,000 x (-20% + 10%) x 1.1111] = $888.89
