Brazilian Real-Denominated Knock-Out Notes Linked to the BOVESPA Index, Payable in U.S. Dollars, due March 8, 2012

General

Key Terms

Index:

The BOVESPA Index (“BOVESPA”) (the “Index”).

Denomination Currency:

Brazilian reais (“BRL”)

Payment Currency:

U.S. dollars (“USD”)

Principal Amount:

BRL 1,000

Exchange Rate:

The “Exchange Rate” on any currency business day will be the BRL/USD exchange rate, as determined by the calculation agent, expressed as the amount of BRL per one USD, as reported by Reuters Group PLC (“Reuters”) on Reuters page “PTAX” at approximately 6:00 p.m., São Paulo Time, on such day.

Payment at Maturity:

At maturity, you will receive a cash payment, converted into U.S. dollars based on the Exchange Rate as of the Observation Date, for each note, equal to the Principal Amount plus the Additional Amount, which may be zero.

Your payment at maturity in U.S. dollar terms is subject to currency exchange risk. Accordingly, you could lose some or all of your initial investment.

Additional Amount:

The Additional Amount per note paid at maturity will equal, subject to conversion into USD:

 
(1)
If a Knock-Out Event has not occurred, the Principal Amount × the Index Return × the Participation Rate; provided that the Additional Amount will not be less than zero; or
 
(2)
If a Knock-Out Event has occurred, the Principal Amount × the Knock-Out Rate. Under these circumstances, the Additional Amount (in BRL terms) you receive at maturity will be equal to BRL50 per note.
  Accordingly, because the Knock-Out Level is 121% of the Initial Index Level and the Participation Rate is 100%, the maximum Additional Amount (in BRL terms)is BRL210 per note.

Participation Rate:

100%

Knock-Out Event:

If the Index closing level is greater than the Knock-Out Level on any day during the period from but excluding the pricing date to and including the Observation Date, a Knock-Out Event will have occurred.

Knock-Out Level:

121% of the Initial Index Level.

Knock-Out Rate:

5%, which results in an Additional Amount (in BRL terms) equal to BRL50 if a Knock-Out Event occurs.

Index Return:

Ending Index Level – Initial Index Level
                Initial Index Level

Initial Index Level:

The Index closing level on the pricing date, which was 68012.10.

Ending Index Level:

The Index closing level on the Observation Date.

Observation Date*:

March 5, 2012

Maturity Date*:

March 8, 2012

CUSIP:

48125XGV2

Additional Key Terms

The BRL/USD Exchange Rate

Exchange rates reflect the amount of one currency that can be exchanged for a unit of another currency.

The Exchange Rate is expressed as the amount of BRL per one USD. As a result, a decrease in the Exchange Rate means that the BRL has appreciated/strengthened relative to the USD. This means that it takes fewer BRL to purchase one USD on the Observation Date than it did on the pricing date. Viewed another way, one BRL can purchase more USD on the Observation Date than it could on the pricing date. A hypothetical Exchange Rate of 1.20 reflects a strengthening of the BRL relative to the USD, as compared to a hypothetical Exchange Rate of 1.60 on the pricing date.

Conversely, an increase in the Exchange Rate means that the BRL has depreciated/weakened relative to the USD. This means that it takes more BRL to purchase one USD on the Observation Date than it did on the pricing date. Viewed another way, one BRL can purchase fewer USD on the Observation Date than it could on the pricing date. A hypothetical Exchange Rate of 2.00 reflects a strengthening of the BRL relative to the USD, as compared to a hypothetical Exchange Rate of 1.60 on the pricing date.

Actual exchange rates on the pricing date and Observation Date will vary from those used in the examples above.

Hypothetical Payment at Maturity (in BRL Terms) for Each Note

The following table illustrates the payment at maturity (including, where relevant, the payment of the Additional Amount) in BRL terms for a note for a hypothetical range of performance for the Index Return from -80% to +80%. The following table and examples assume an Initial Index Level of 68000 and a Knock-Out Level of 82280 (which is equal to 121% of the hypothetical Initial Index Level), and reflect the Participation Rate of 100% and the Knock-Out Rate of 5%. The actual payment at maturity of your notes will be converted into USD based on the Exchange Rate on the Observation Date. See “Hypothetical Examples of the Conversion of the Payment at Maturity into U.S. Dollars” below to see how such conversion and changes in the Exchange Rate can affect the payment at maturity in USD terms. The following results are based solely on the hypothetical example cited. You should consider carefully whether the notes are suitable to your investment goals. The numbers appearing in the table and examples below have been rounded for ease of analysis.

(1) The Index closing level is less than or equal to 82280 on each day from but excluding the pricing date to and including the Observation Date.
(2) The Index closing level is greater than 82280 on at least one day from but excluding the pricing date to and including the Observation Date.

Hypothetical Examples of Amounts Payable at Maturity (in BRL Terms)

The following examples illustrate how the total returns in BRL terms set forth in the table on the previous page are calculated.

Example 1: The Index closing level increases from the Initial Index Level of 68000 to an Ending Index Level of 74800 and the Index closing level did not exceed the Knock-Out Level of 82280 on any day from but excluding the pricing date to and including the Observation Date. Because (i) the Ending Index Level of 74800 is greater than the Initial Index Level of 68000 and (ii) a Knock-Out Event has not occurred, the Additional Amount is equal to BRL100 and the payment at maturity is equal to BRL1,100 per note in BRL terms, calculated as follows:

BRL1,000 + (BRL1,000 × [(74800-68000)/68000] × 100%) = BRL1,100

Example 2: The Index closing level declines from the Initial Index Level of 68000 to an Ending Index Level of 54400, and the Index closing level did not exceed the Knock-Out Level of 82280 on any day from but excluding the pricing date to and including the Observation Date. Because (i) the Ending Index Level of 54400 is less than the Initial Index Level of 68000 and (ii) a Knock-Out Event has not occurred, the payment at maturity per note in BRL terms is the Principal Amount of BRL1,000.

Example 3: The Index closing level increases from the Initial Index Level of 68000 to an Ending Index Level of 95200 and the Index closing level did not exceed the Knock-Out Level of 82280 on any day until the Observation Date. Because the Ending Index Level of 95200 is greater than the Knock-Out Level of 82280, a Knock-Out Event has occurred. Accordingly, the Additional Amount is equal to BRL50 and the payment at maturity per note is equal to BRL1,050 in BRL terms, calculated as follows:

BRL1,000 + (BRL1,000 × 5%) = BRL1,050

Example 4: The Index closing level increases from the Initial Index Level of 68000 to an Ending Index Level of 74800 and the Index closing level exceeded the Knock-Out Level of 82280 on at least one day during the period from but excluding the pricing date to and including the Observation Date. Even though the Ending Index Level of 74800 is greater than the Initial Index Level of 68000 by 10%, because a Knock-Out Event has occurred, the Additional Amount is equal to BRL50 and the payment at maturity per note is equal to BRL1,050 in BRL terms, calculated as follows:

BRL1,000 + (BRL1,000 × 5%) = BRL1,050

Example 5: The Index closing level declines from the Initial Index Level of 68000 to an Ending Index Level of 61200, and the Index closing level exceeded the Knock-Out Level of 82280 on at least one day during the period from but excluding the pricing date to and including the Observation Date. Even though the Ending Index Level of 61200 is less than the Initial Index Level of 68000, because a Knock-Out Event has occurred, the Additional Amount is equal to BRL50 and the payment at maturity per note is equal to BRL1,050 in BRL terms, calculated as follows:

BRL1,000 + (BRL1,000 × 5%) = BRL1,050

Hypothetical Examples of the Conversion of the Payment at Maturity into U.S. Dollars

The following examples illustrate how the payment at maturity will be converted into U.S. dollars in different hypothetical scenarios.  The examples below assume that the Exchange Rate on the pricing date is 1.60, and therefore your initial investment in a note in USD terms is equal to US$625 (BRL1,000/1.60).  The hypothetical payment at maturity set forth below are for illustrative purposes only and may not be the actual payment at maturity.  The numbers appearing in the following examples have been rounded for ease of analysis.

Example 1: A Knock-Out Event has not occurred, the Index Return is not more than 0% and the Exchange Rate on the Observation Date is 1.80. Therefore, the payment at maturity per note in BRL terms is BRL1,000.

The payment at maturity in USD terms = BRL1,000/1.80 = US$555.56

In this example, even though a Knock-Out Event has not occurred and the Index Return is not more than 0%, you lose a portion of your initial investment in USD terms (a loss of $69.44 per note, or a total return in USD terms of -11.11%) because the BRL has weakened against the USD.

Example 2: A Knock-Out Event has not occurred, the Index Return is not more than 0% and the Exchange Rate on the Observation Date is 1.50. Therefore, the payment at maturity per note in BRL terms is BRL1,000.

The payment at maturity in USD terms = BRL1,000/1.50 = US$666.67

In this example, even though a Knock-Out Event has not occurred and the Index Return is not more than 0%, you received a payment at maturity that is greater than your initial investment in USD terms (a gain of $41.67 per note, or a total return in USD terms of 6.67%) because the BRL has strengthened against the USD.

Example 3: A Knock-Out Event has not occurred, the Index Return is 10% and the Exchange Rate on the Observation Date is 1.80. Therefore, the payment at maturity per note in BRL terms is BRL1,100.

The payment at maturity in USD terms = BRL1,100/1.80 = US$611.11

In this example, even though a Knock-Out Event has not occurred and the Index Return is 10%,  you lose a portion of your initial investment in USD terms (a loss of $13.89 per note, or a total return in USD terms of -2.22%) because the BRL has weakened against the USD.

Example 4: A Knock-Out Event has not occurred, the Index Return is 10% and the Exchange Rate on the Observation Date is 1.70. Therefore, the payment at maturity per note in BRL terms is BRL1,100.

The payment at maturity in USD terms = BRL1,100/1.70 = US$647.06

In this example, even though a Knock-Out Event has not occurred and the Index Return is 10%,  the total return on your initial investment in USD terms is less than 10% (a gain of $22.06 per note, or a total return in USD terms of 3.53%) because the BRL has weakened against the USD.

Example 5: A Knock-Out Event has not occurred, the Index Return is 10% and the Exchange Rate on the Observation Date is 1.50. Therefore, the payment at maturity per note in BRL terms is BRL1,100.

The payment at maturity in USD terms = BRL1,100/1.50 = US$733.33

In this example, even though a Knock-Out Event has not occurred and the Index Return is 10%, the total return on your initial investment in USD terms is greater than 10% (a gain of $108.33 per note, or a total return in USD terms of 17.33%) because the BRL has strengthened against the USD.

Example 6: A Knock-Out Event has occurred, and the Exchange Rate on the Observation Date is 1.90. Therefore, the payment at maturity per note in BRL terms is BRL1,050, regardless of the Index Return.

The payment at maturity in USD terms = BRL1,050/1.90 = US$552.63

In this example, even though the Knock-Out Rate is 5%, you lose a portion of your initial investment in USD terms (a loss of $72.37 per note, or a total return in USD terms of -11.58%) because the BRL has weakened against the USD.

Example 7: A Knock-Out Event has occurred, and the Exchange Rate on the Observation Date is 1.40. Therefore, the payment at maturity per note in BRL terms is BRL1,050, regardless of the Index Return.

The payment at maturity in USD terms = BRL1,050/1.40 = US$750.00

In this example, even though the Knock-Out Rate is 5%, the total return on your initial investment in USD terms is greater than 5% (a gain of $125 per note, or a total return in USD terms of 20%) because the BRL has strengthened against the USD.
