Key Terms

Basket:	An equally weighted basket of four currencies (each a “Basket Currency” and together the “Basket Currencies”) that measures the performance of the Basket Currencies relative to the U.S. dollar (the “Basket”).
Basket Currency Weights:	The following table sets forth the Basket Currencies, the Starting Spot Rate for each Basket Currency, the applicable Reuters Page and the weighting of each Basket Currency:

Basket Currency	Starting Spot Rate	Reuters Page	Percentage Weight of Basket
Australian dollar (AUD)	0.8337††	WMRSPOT12	25%
Canadian dollar (CAD)	0.8959†	WMRSPOT09	25%
European Union euro (EUR)	1.3659††	WMRSPOT05	25%
Japanese yen (JPY)	0.00844†	WMRSPOT12	25%

	† The Starting Spot Rate for each of the Canadian dollar and the Japanese yen was determined by the calculation agent in good faith and in a commercially reasonable manner at approximately 9:00 a.m., New York City time, on the pricing date taking into account the quotient of one divided by the rates displayed on the applicable Reuters page.
	†† The Starting Spot Rate for each of the Australian dollar and the European Union euro was determined by the calculation agent in good faith and in a commercially reasonable manner at approximately 9:00 a.m., New York City time, on the pricing date taking into account the rates displayed on the applicable Reuters page.
	For information about the risks related to this discretion, see “Selected Risk Considerations — Potential Conflicts” on page PS-2 of this pricing supplement.
Reference Currency:	The U.S. dollar
Payment at Maturity:	At maturity, you will receive a cash payment, for each $1,000 principal amount note, of $1,000 plus the Additional Amount, which may be zero.
Additional Amount:	The Additional Amount per $1,000 principal amount note paid at maturity will equal $1,000 x the Basket Return x the Participation Rate; provided that the Additional Amount will not be less than zero.
Participation Rate:	140%
Basket Return:	Ending Basket Level – Starting Basket Level                   Starting Basket Level
Starting Basket Level:	Set equal to 100 on the pricing date, which was April 25, 2007.
Ending Basket Level:	The Basket Closing Level on the Observation Date.
Basket Closing Level:	The Basket Closing Level on the Observation Date will be calculated as follows:
	100 x [1 + (AUD Return * 1/4) + (CAD Return * 1/4) + (EUR Return * 1/4) + (JPY Return * 1/4)]
	The CAD Return and JPY Return are the respective performances of those Basket Currencies, expressed as a percentage, from the Spot Rate of the relevant Basket Currency in the interbank market on the pricing date to the Spot Rate of such Basket Currency on the Observation Date. The Spot Rates on a given date that falls after the pricing date are the amounts reported by Reuters Group PLC on page WMRSPOT09 (for the CAD Return) and page WMRSPOT12 (for the JPY Return), and are expressed as one divided by the amount of Basket Currency per one Reference Currency at approximately 6:00 p.m., New York City time, on such date.
	The AUD Return and EUR Return are the respective performances of those Basket Currencies, expressed as a percentage, from the Spot Rate of the relevant Basket Currency in the interbank market on the pricing date to the Spot Rate of such Basket Currency on the Observation Date. The Spot Rates on a given date that falls after the pricing date are the amounts reported by Reuters Group PLC on page WMRSPOT12 (for the AUD Return) and page WMRSPOT05 (for the EUR Return), and are expressed as the amount of Reference Currency per one unit of Basket Currency at approximately 6:00 p.m., New York City time, on such date (together with the respective CAD and JPY spot rates as described above, the “Spot Rates” and each, a “Spot Rate”).
	For additional information, see “Description of Notes — Payment at Maturity” in the accompanying product supplement no. 49-II.

Selected Purchase Considerations

• PRESERVATION OF CAPITAL AT MATURITY — You will receive at least 100% of the principal amount of your notes if you hold the notes to maturity, regardless of the performance of the Basket. Because the notes are our senior unsecured obligations, payment of any amount at maturity is subject to our ability to pay our obligations as they become due.
• APPRECIATION POTENTIAL — At maturity, in addition to your principal, for each $1,000 principal amount note you will receive a payment equal to $1,000 x the Basket Return x the Participation Rate, provided that this payment (Additional Amount) will not be less than zero.
• DIVERSIFICATION AMONG THE BASKET CURRENCIES — The return on the notes is linked to the performance of a basket of global currencies, which we refer to as the Basket Currencies, relative to the U.S. dollar and enable you to participate in potential increases in the value of the Basket Currencies, relative to the U.S. dollar, during the term of the notes. The Basket derives its value from an equally weighted group of currencies consisting of the Australian dollar, the Canadian dollar, the European Union euro and the Japanese yen.
• TAXED AS CONTINGENT PAYMENT DEBT INSTRUMENTS — You should review carefully the section entitled “Certain U.S. Federal Income Tax Consequences” in the accompanying product supplement no. 49-II. Subject to the limitations described therein, and based on certain factual representations received from us, in the opinion of our special tax counsel, Davis Polk & Wardwell, the notes will be treated for U.S. federal income tax purposes as “contingent payment debt instruments.” You will generally be required to recognize interest income in each year at the “comparable yield,” as determined by us, although we may not make any payments with respect to the notes until maturity. Interest included in income will increase your basis in the notes. Generally, amounts received at maturity or earlier sale or disposition in excess of your basis will be treated as additional interest income while any loss will be treated as an ordinary loss to the extent of all previous inclusions with respect to the notes, which will be deductible against other income (e.g., employment and interest income), with the balance treated as capital loss, which may be subject to limitations. Purchasers who are not initial purchasers of notes at the issue price should consult their tax advisers with respect to the tax consequences of an investment in the notes, including the treatment of the difference, if any, between such purchasers’ basis in the notes and the notes’ adjusted issue price.
• COMPARABLE YIELD AND PROJECTED PAYMENT SCHEDULE — We have determined that the “comparable yield” is an annual rate of 5.14%, compounded semiannually. Based on our determination of the comparable yield, the “projected payment schedule” per $1,000 note consists of a single payment at maturity, equal to $1,079.26.
  Assuming a semi-annual accrual period, the following table states the amount of OID that will accrue with respect to a note during each calendar period, based upon our determination of the comparable yield and the projected payment schedule:

Calendar Period	Accrued OID During Calendar Period (per $1,000 note)	Total Accrued OID from Original Issue Date per $1,000 note as of End of Calendar Period
April 30, 2007 through December 31, 2007	$34.49	$34.49
January 1, 2008 through October 31, 2008	$44.77	$79.26

Neither the comparable yield nor the projected payment schedule constitutes a representation by us regarding the actual amount, if any, that we will pay on the notes.

Selected Risk Considerations

An investment in the notes involves significant risks. Investing in the notes is not equivalent to investing directly in the Basket Currencies or any of contracts related to the Basket Currencies. These risks are explained in more detail in the “Risk Factors” section of the accompanying product supplement no. 49-II dated March 7, 2007.

• CURRENCY MARKET RISK — The return on the notes at maturity is linked to the performance of the Basket, and will depend on whether, and the extent to which, the Basket Return is positive. Any positive Basket Return will depend on the aggregate performance of the Basket Currencies relative to the U.S. dollar. For example, the value of any currency, including the Basket Currencies, may be affected by complex political and economic factors. The value of each Basket Currency, relative to the U.S. dollar, is, at any moment, the result of the interaction between many factors directly or indirectly affecting economic or political developments in the originating country (or countries) of each Basket Currency and the United States, including economic and political developments in other countries. Therefore, in calculating the Ending Basket Level, increases in the exchange rates of one or more of the Basket Currencies may be moderated, or more than offset, by lesser increases or decreases in the exchange rates of the remaining Basket Currencies. YOU WILL RECEIVE NO MORE THAN THE FULL PRINCIPAL AMOUNT OF YOUR NOTES AT MATURITY IF THE BASKET RETURN IS ZERO OR NEGATIVE.
• THE NOTES MIGHT NOT PAY AS MUCH AS AN INVESTMENT IN THE INDIVIDUAL BASKET CURRENCIES — You may receive a lower payment at maturity than you would have received if you had invested in the Basket Currencies individually, a combination of Basket Currencies or contracts related to the Basket Currencies for which there is an active secondary market. If the Ending Basket Level does not exceed the Starting Basket Level, the Additional Amount will be zero. Because the Ending Basket Level will be calculated based on the Basket Closing Level on the Observation Date, the level of the Basket at the maturity date or at other times during the term of the notes could be higher than the Ending Basket Level. This difference could be particularly large if there is a significant decrease in the level of the Basket during the latter portion of the term of the notes or if there is significant volatility in the Basket level during the term of the notes, especially on dates near the Observation Date.
• CHANGES IN THE VALUE OF THE EQUALLY WEIGHTED BASKET CURRENCIES MAY OFFSET EACH OTHER — Because the performance of the Basket is determined by the performance of the Australian dollar, the Canadian dollar, the European Union euro and the Japanese yen relative to the U.S. dollar, your notes will be exposed to currency exchange rate risk

with respect to Australia, Canada, Europe, Japan and the United States. Movements in the exchange rates of the Basket Currencies may not correlate with each other. As a result, your investment in the notes may only yield a positive return if there occurs a broad-based rise in foreign currency values as compared to the U.S. dollar across diverse markets over the term of the notes. Therefore, for example, in calculating the Ending Basket Level, an increase in the Spot Rate of the Australian dollar may be moderated, or more than offset by, lesser increases or declines in the Spot Rate of the Japanese yen.
• THE NOTES MAY NOT PAY MORE THAN THE PRINCIPAL AMOUNT AT MATURITY — If the Ending Basket Level does not exceed the Starting Basket Level, the Additional Amount will be zero. Because the Ending Basket Level will be calculated based on the Basket Closing Level on the Observation Date, the level of the Basket at the maturity date or at other times during the term of the notes could be higher than the Ending Basket Level. This will be true even if the value of the Basket was higher than the Starting Basket Level at some time during the term of the notes but later falls below the Starting Basket Level on the Observation Date.
• CERTAIN BUILT-IN COSTS ARE LIKELY TO ADVERSELY AFFECT THE VALUE OF THE NOTES PRIOR TO MATURITY — While the payment at maturity described in this pricing supplement is based on the full principal amount of your notes, the original issue price of the notes includes the agent’s commission and the cost of hedging our obligations under the notes through one or more of our affiliates. As a result, the price, if any, at which JPMSI will be willing to purchase notes from you in secondary market transactions will likely be lower than the original issue price and any sale prior to the maturity date could result in a substantial loss to you. The notes are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your notes to maturity.
• NO INTEREST PAYMENTS — As a holder of the notes, you will not receive interest payments.
• LACK OF LIQUIDITY — The notes will not be listed on any securities exchange. JPMSI intends to offer to purchase the notes in the secondary market but is not required to do so. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the notes easily. Because other dealers are not likely to make a secondary market for the notes, the price at which you may be able to trade your notes is likely to depend on the price, if any, at which JPMSI is willing to buy the notes.
• POTENTIAL CONFLICTS — We and our affiliates play a variety of roles in connection with the issuance of the notes, including acting as calculation agent and hedging our obligations under the notes. In performing these duties, the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the notes. For example, one of JPMSI’s duties as calculation agent involves determining the Starting Spot Rate in the manner set forth on the cover page of this pricing supplement. The Starting Spot Rate may vary, and may vary significantly, from the rates displayed in publicly available sources at 9:00 a.m., New York City time, on the pricing date. If the calculation agent determines that the Starting Spot Rate for one or more Basket Currencies exceeds that reflected in the publicly available information, each affected Basket Currency must achieve a higher level for you to receive more than the principal amount of your notes at maturity. JPMSI will not have any obligation to consider your interests as a holder of the notes in making this determination.
• MANY ECONOMIC AND MARKET FACTORS WILL IMPACT THE VALUE OF THE NOTES — In addition to the level of the Basket on any day, the value of the notes will be affected by a number of economic and market factors that may either offset or magnify each other, including:
  • the expected volatility in the Basket Currencies and the U.S. dollar;
  • the time to maturity of the notes;
  • interest and yield rates in the market generally as well as in each of the Basket Currencies’ countries and in the United States;
  • the exchange rate and the volatility of the exchange rate among each of the Basket Currencies;
  • changes in correlation between the Basket Currency exchange rates;
  • suspension or disruption of market trading in any or all of the Basket Currencies or the U.S. dollar;
  • a variety of economic, financial, political, regulatory or judicial events; and
  • our creditworthiness, including actual or anticipated downgrades in our credit ratings.

What Is the Payment at Maturity on the Notes Assuming a Range of Performance for the Basket?

The following table illustrates the payment at maturity (including, where relevant, the payment of the Additional Amount) for a $1,000 principal amount note for a hypothetical range of performance for the Basket Return from -80% to +80% and reflects the Participation Rate of 140%. The hypothetical payments at maturity (including, where relevant, the Additional Amount) set forth below are for illustrative purposes only and may not be the actual payment at maturity applicable to a purchaser of the notes. You should consider carefully whether the notes are suitable to your investment goals. The numbers appearing in the following table and examples below have been rounded for ease of analysis.

Ending Basket Level	Basket Return	Basket Return x Participation Rate (140%)	Additional Amount		Principal		Payment at Maturity
180	80%	112%	$1,120	+	$1,000	=	$2,120
170	70%	98%	$980	+	$1,000	=	$1,980
160	60%	84%	$840	+	$1,000	=	$1,840
150	50%	70%	$700	+	$1,000	=	$1,700
140	40%	56%	$560	+	$1,000	=	$1,560
130	30%	42%	$420	+	$1,000	=	$1,420
120	20%	28%	$280	+	$1,000	=	$1,280
110	10%	14%	$140	+	$1,000	=	$1,140
105	5%	7%	$70	+	$1,000	=	$1,070
100	0%	0%	$0	+	$1,000	=	$1,000
90	-10%	0%	$0	+	$1,000	=	$1,000
80	-20%	0%	$0	+	$1,000	=	$1,000
70	-30%	0%	$0	+	$1,000	=	$1,000
60	-40%	0%	$0	+	$1,000	=	$1,000
50	-50%	0%	$0	+	$1,000	=	$1,000
40	-60%	0%	$0	+	$1,000	=	$1,000
30	-70%	0%	$0	+	$1,000	=	$1,000
20	-80%	0%	$0	+	$1,000	=	$1,000

Hypothetical Examples of Amounts Payable at Maturity

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

Example 1: The level of the Basket increases from the Starting Basket Level of 100 to an Ending Basket Level of 120. Because the Ending Basket Level of 120 is greater than the Starting Basket Level of 100, the Additional Amount is equal to $280 and the final payment at maturity is equal to $1,280 per $1,000 principal amount note, calculated as follows:

$1,000 + ($1,000 x [(120-100)/100] x 140%) = $1,280

Example 2: The level of the Basket decreases from the Starting Basket Level of 100 to an Ending Basket Level of 60. Because the Ending Basket Level of 60 is lower than the Starting Basket Level of 100, the final payment per $1,000 principal amount note at maturity is the principal amount of $1,000.

Example 3: The level of the Basket increases from the Starting Basket Level of 100 to an Ending Basket Level of 110. Because the Ending Basket Level of 110 is greater than the Starting Basket Level of 100, the Additional Amount is equal to $140 and the final payment at maturity is equal to $1,140 per $1,000 principal amount note, calculated as follows:

$1,000 + ($1,000 x [(110-100)/100] x 140%) = $1,140

Historical Information

The first four graphs below show the historical weekly performance of each Basket Currency expressed in terms of the conventional market quotation, as shown on Bloomberg Financial Markets, for each currency (which, in the case of the Canadian dollar and the Japanese yen is the amount of the applicable Basket Currency that can be exchanged for one U.S. dollar and, in the case of the Australian dollar and the European Union euro, is the amount of U.S. dollars that can be exchanged for one unit of the applicable Basket Currency, and which, in each case, we refer to in this pricing supplement as the exchange rate) from January 4, 2002 through April 20, 2007. The exchange rates of the Australian dollar, the Canadian dollar, the European Union euro and the Japanese yen at approximately 9:00 a.m., New York City time, on April 25, 2007, were 0.8337, 1.1162, 1.3659 and 118.46, respectively.

The exchange rates displayed in the graphs below are for illustrative purposes only and do not form part of the calculation of the Basket Return. The value of the Basket, and thus the Basket Return, increase when the individual Basket Currencies appreciate in value against the U.S. dollar. Therefore, the Basket Return is calculated using Spot Rates for each currency expressed, for the Canadian dollar and the Japanese yen, as one divided by the amount of Basket Currency per one U.S. dollar, which is the inverse of the conventional market quotation for each such Basket Currency set forth in the applicable graphs below and, for the Australian dollar and the European Union euro, as the amount of U.S. dollars per one unit of Basket Currency, which is largely consistent with the approach used to determine the conventional market quotation for each such Basket Currency set forth in the applicable graphs below.

The last graph below shows the historical weekly performance of the Basket from January 4, 2002 through April 20, 2007, assuming that the Basket closing level on January 4, 2002 was 100, that each Basket Currency had a 1/4 weight in the Basket on that date and that the closing spot rates of each Basket Currency on the relevant dates were the Spot Rates on such dates. The closing spot rates and the historical weekly Basket performance data in such graph were determined using the rates reported by Bloomberg Financial Markets, were calculated in the manner set forth under “Basket Currency Weights” on the cover of this pricing supplement and may not be indicative of the Basket performance using the Spot Rates of the Basket Currencies at approximately 6:00 p.m., New York City time (or, solely with respect to the Spot Rates on the pricing date, at approximately 9:00 a.m., New York City time on such date), that would be derived from the applicable Reuters page.

The Spot Rates of the Australian dollar, the Canadian dollar, the European Union euro and the Japanese yen, at approximately 9:00 a.m. New York City time, on April 25, 2007, were 0.8337, 0.8959, 1.3659 and 0.00844 respectively, calculated in the manner set forth on the cover of this pricing supplement.

We obtained the exchange rates and the data needed to construct the graph which displays the weekly performance of the Basket from Bloomberg Financial Markets. We make no representation or warranty as to the accuracy or completeness of the information obtained from Bloomberg Financial Markets. The historical performance of each Basket Currency and the Basket should not be taken as an indication of future performance, and no assurance can be given as to the closing level of any of the Basket Currencies on the Observation Date. We cannot give you assurance that the performance of the Basket will result in the return of more than the principal amount of your initial investment.
