Key Terms

Index:	The S&P 500® Index (“SPX”) (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 2, subject to a Maximum Total Return on the notes of 15.00% at maturity. For example, if the Index Return is equal to or greater than 7.5%, you will receive the Maximum Total Return on the notes of 15.00%, which entitles you to a maximum payment at maturity of $1,150 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% 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%)]
	If the Ending Index Level declines from the Initial Index Level by more than 10%, you could lose up to $900 per $1,000 principal amount note.
Buffer Amount:	10%, which results in a minimum payment of $100 per $1,000 principal amount note.
Index Return:	Ending Index Level – Initial Index Level                Initial Index Level
Initial Index Level:	1209.18, which was the Index closing level on the pricing date.
Ending Index Level:	The Index closing level on the Observation Date.
Observation Date:	March 26, 2010†
Maturity Date:	March 31, 2010†
CUSIP:	48123LME1

Additional Terms Specific to the Notes

You should read this pricing supplement together with the prospectus dated December 1, 2005, as supplemented by the prospectus supplement dated October 12, 2006 relating to our Series E medium-term notes of which these notes are a part, and the more detailed information contained in product supplement no. 39-XI dated June 11, 2008. This pricing supplement, together with the documents listed below, contains the terms of the notes, supplements the term sheet related hereto dated August 29, 2008 and supersedes all other prior or contemporaneous oral statements as well as any other written materials including preliminary or indicative pricing terms, correspondence, trade ideas, structures for implementation, sample structures, fact sheets, brochures or other educational materials of ours. You should carefully consider, among other things, the matters set forth in “Risk Factors” in the accompanying product supplement no. 39-XI, as the notes involve risks not associated with conventional debt securities. We urge you to consult your investment, legal, tax, accounting and other advisers before you invest in the notes.

Selected Purchase Considerations

• APPRECIATION POTENTIAL — The notes provide the opportunity to enhance equity returns by multiplying a positive Index Return by 2, up to the Maximum Total Return on the notes of 15.00%, or a maximum payment at maturity of $1,150 for every $1,000 principal amount note. 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.
• LIMITED PROTECTION AGAINST LOSS — Payment at maturity of the principal amount of the notes is protected against a decline in the Ending Index Level, as compared to the Initial Index Level, of up to 10%. If the Ending Index Level declines by more than 10%, for every 1% decline of the Index beyond 10%, you will lose an amount equal to 1% of the principal amount of your notes. Accordingly, at maturity you will receive a payment equal to at least $100 for each $1,000 principal amount note.
• DIVERSIFICATION OF THE S&P 500^® INDEX — The return on the notes is linked to the S&P 500^® Index. The S&P 500^® Index consists of 500 component stocks selected to provide a performance benchmark for the U.S. equity markets. For additional information about the Index, see the information set forth under “The S&P 500^® Index” in the accompanying product supplement no. 39-XI.
• CAPITAL GAINS TAX TREATMENT — You should review carefully the section entitled “Certain U.S. Federal Income Tax Consequences” in the accompanying product supplement no. 39-XI. As described therein, we and you will agree to characterize and treat the notes for U.S. federal income tax purposes as “open transactions”. Subject to the limitations described therein, and based on certain factual representations received from us, in the opinion of our special tax counsel, Sidley Austin LLP, it is reasonable to treat your purchase and ownership of the notes as an “open transaction” for U.S. federal income tax purposes. Assuming this characterization is respected, your gain or loss on the notes should be treated as long-term capital gain or loss if you hold the notes for more than a year, whether or not you are an initial purchaser of notes at the issue price. However, the Internal Revenue Service (the “IRS”) or a court may not respect this characterization or treatment of the notes, in which case the timing and character of any income or loss on the notes could be significantly and adversely affected. For example, the notes could be treated either as subject (in whole or in part) to the “constructive ownership transaction” rules of Section 1260 of the Internal Revenue Code, as discussed in the section entitled “Certain U.S. Federal Income Tax Consequences” in the accompanying product supplement no. 39-XI, or as “contingent payment debt instruments.”
  Moreover, on December 7, 2007, the Treasury Department and the IRS released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments, such as the notes. The notice focuses in particular on whether to require holders of these instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments; the relevance of factors such as the nature of the underlying property to which the instruments are linked; the degree, if any, to which income (including any mandated accruals) realized by Non-U.S. Holders should be subject to withholding tax; and whether these instruments are or should be subject to the “constructive ownership” regime, which very generally can operate to recharacterize certain long-term capital gain as ordinary income that is subject to an interest charge. While the notice requests comments on appropriate transition rules and effective dates, any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the notes, possibly with retroactive effect. Both U.S. and Non-U.S. Holders should consult their tax advisers regarding the U.S. federal income tax consequences of an investment in the notes, including possible alternative treatments and the issues presented by this notice.

Selected Risk Considerations

An investment in the notes involves significant risks. Investing in the notes is not equivalent to investing directly in any of the component stocks of the Index. These risks are explained in more detail in the “Risk Factors” section of the accompanying product supplement no. 39-XI dated June 11, 2008.

• YOUR INVESTMENT IN THE NOTES MAY RESULT IN A LOSS — The notes do not guarantee any return of principal in excess of $100 per $1,000 principal amount note. The return on the notes at maturity is linked to the performance of the Index and will depend on whether, and the extent to which, the Index Return is positive or negative. Your investment will be exposed to any decline in the Ending Index Level, as compared to the Initial Index Level, beyond the 10% buffer. Accordingly, you could lose up to $900 for each $1,000 principal amount note that you invest in.
• YOUR MAXIMUM GAIN ON THE NOTES IS LIMITED TO THE MAXIMUM TOTAL RETURN — If the Ending Index Level is greater than the Initial Index Level, for each $1,000 principal amount note, you will receive at maturity $1,000 plus an additional amount that will not exceed the Maximum Total Return of 15.00% of the principal amount, regardless of the appreciation in the Index, which may be significant.
• 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 estimated cost of hedging our obligations under the notes through one or more of our affiliates. As a result, and as a general matter, the price, if any, at which JPMSI will be willing to purchase notes from you in secondary market transactions, if at all, 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. This secondary market price will also be affected by a number of factors aside from the agent’s commission and hedging costs, including those set forth under “Many Economic and Market Factors Will Impact the Value of the Notes” below.
  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 OR DIVIDEND PAYMENTS OR VOTING RIGHTS — As a holder of the notes, you will not receive interest payments, and you will not have voting rights or rights to receive cash dividends or other distributions or other rights that holders of securities composing the Index would have.
• 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.
• WE ARE CURRENTLY ONE OF THE COMPANIES THAT MAKE UP THE INDEX — We are currently one of the companies that make up the Index. To our knowledge, we are not currently affiliated with any other issuers the equity securities of which are included in the Index. We will not have any obligation to consider your interests as a holder of the notes in taking any corporate action that might affect the value of the Index and 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. In addition, we are currently one of the companies that make up the Index. We will not have any obligation to consider your interests as a holder of the notes in taking any corporate action that might affect the value of the Index and the notes.
• MANY ECONOMIC AND MARKET FACTORS WILL IMPACT THE VALUE OF THE NOTES — In addition to the level of the Index 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 of the Index;
  • the time to maturity of the notes;
  • the dividend rate on the common stocks underlying the Index;
  • interest and yield rates in the market generally;
  • 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 Total Return on the Notes at Maturity Assuming a Range of Performance for the Index?

The following table illustrates the hypothetical total return at maturity on the notes. The “total return” as used in this pricing supplement is the number, expressed as a percentage, that results from comparing the payment at maturity per $1,000 principal amount note to $1,000. The hypothetical total returns set forth below assume an Initial Index Level of 1200 and reflect the Maximum Total Return on the notes of 15.00%. The hypothetical total returns set forth below are for illustrative purposes only and may not be the actual total returns applicable to a purchaser of the notes. The numbers appearing in the following table and examples have been rounded for ease of analysis.

Ending Index Level	Index Return	Total Return
1800.00	50.00%	15.00%
1680.00	40.00%	15.00%
1560.00	30.00%	15.00%
1440.00	20.00%	15.00%
1320.00	10.00%	15.00%
1290.00	7.50%	15.00%
1260.00	5.00%	10.00%
1230.00	2.50%	5.00%
1212.00	1.00%	2.00%
1200.00	0.00%	0.00%
1140.00	-5.00%	0.00%
1080.00	-10.00%	0.00%
1020.00	-15.00%	-5.00%
960.00	-20.00%	-10.00%
840.00	-30.00%	-20.00%
720.00	-40.00%	-30.00%
600.00	-50.00%	-40.00%
480.00	-60.00%	-50.00%
360.00	-70.00%	-60.00%
240.00	-80.00%	-70.00%
120.00	-90.00%	-80.00%
0.00	-100.00%	-90.00%

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 Index increases from the Initial Index Level of 1200 to an Ending Index Level of 1260. Because the Ending Index Level of 1260 is greater than the Initial Index Level of 1200 and the Index Return of 5% multiplied by 2 does not exceed the Maximum Total Return of 15.00%, 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 1200 to an Ending Index Level of 1140. Because the Ending Index Level of 1140 is less than the Initial Index Level of 1200 by not more than the Buffer Amount of 10%, the investor receives 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 1200 to an Ending Index Level of 1320. Because the Ending Index Level of 1320 is greater than the Initial Index Level of 1200 and the Index Return of 10% multiplied by 2 exceeds the Maximum Total Return of 15.00%, the investor receives a payment at maturity of $1,150 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 1200 to an Ending Index Level of 960. Because the Ending Index Level of 960 is less than the Initial Index Level of 1200 by more than the Buffer Amount of 10%, the investor receives a payment at maturity of $900 per $1,000 principal amount note, calculated as follows:

$1,000 + [$1,000 x (-20% + 10%)] = $900

Example 5: The level of the Index decreases from the Initial Index Level of 1200 to an Ending Index Level of 0. Because the Ending Index Level of 0 is less than the Initial Index Level of 1200 by more than the Buffer Amount of 10%, the investor receives a payment at maturity of $100 per $1,000 principal amount note, which reflects the principal protection provided by the Buffer Amount of 10%, calculated as follows:

$1,000 + [$1,000 x (-100% + 10%)] = $100
