Senior Fixed to Floating Rate Notes due May 31, 2021

The Notes

The notes offered are senior unsecured obligations of JPMorgan Chase & Co. Interest on the notes will accrue in (i) Year 1, at a fixed rate equal to 4.25% per annum and (ii) Year 2 to maturity, at a variable rate equal to the year-over-year changes in the CPI plus a spread of 1.50% per annum and subject to the maximum interest rate of 7.00% per annum and minimum interest rate of 0.00% per annum, as determined on the applicable interest determination date. We describe the basic features of these notes in the sections of the accompanying prospectus called “Description of Debt Securities,” the accompanying prospectus supplement called “Description of Notes” and the accompanying product supplement no. MS-13-A-I called “Description of Notes,” subject to and as modified by the provisions described above. All payments on the notes are subject to the credit risk of JPMorgan Chase & Co.

Additional Provisions

Consumer Price Index

The amount of interest payable on the notes on each interest payment date after Year 1 will be linked to year-over-year changes in the Consumer Price Index (plus a spread). The Consumer Price Index for purposes of the notes is the non-seasonally adjusted U.S. City Average All Items Consumer Price Index for All Urban Consumers (“CPI”), reported monthly by the Bureau of Labor Statistics of the U.S. Department of Labor (“BLS”) and published on Bloomberg screen CPURNSA or any successor service. The CPI for a particular month is published during the following month.

The CPI is a measure of the average change in consumer prices over time for a fixed market basket of goods and services, including food, clothing, shelter, fuels, transportation, charges for doctors’ and dentists’ services and drugs. In calculating the index, price changes for the various items are averaged together with weights that represent their importance in the spending of urban households in the United States. The contents of the market basket of goods and services and the weights assigned to the various items are updated periodically by the BLS to take into account changes in consumer expenditure patterns. The CPI is expressed in relative terms in relation to a time base reference period for which the level is set at 100.0. The base reference period for these notes is the 1982-1984 average.

Interest Rate

The interest rate for the notes during Year 1 will be 4.25% per annum. The interest rate for the notes being offered for each interest payment period during the term of the notes following Year 1 will be the rate determined as of the applicable interest determination date pursuant to the following formula:

Interest Rate = CPIt — CPIt-12

CPIt-12
+ Spread per annum; subject to the maximum
interest rate and the minimum interest rate

where:

CPIt = CPI for the applicable Reference Month, as published on Bloomberg screen CPURNSA;

CPIt-12 = CPI for the twelfth month prior to the applicable Reference Month, as published on Bloomberg screen                      CPURNSA;

Spread = 1.50% per annum;

Maximum interest rate = 7.00% per annum; and

Minimum interest rate = 0.00% per annum.

In no case will the interest rate for the notes for any monthly interest payment period be less than the minimum interest rate of 0.00% per annum or greater than the maximum interest rate of 7.00% per annum. The amount

Page 2




Senior Fixed to Floating Rate Notes due May 31, 2021

of interest payable on the notes on each interest payment date will be calculated using a 30/360 day-count convention.

CPIt for any interest reset date is the CPI for the second calendar month, which we refer to as the “reference month,” prior to the month of such interest reset date as published and reported in the calendar month immediately prior to such interest reset date.

For example, for the interest payment period from and including May 31, 2012 to but excluding June 30, 2012, CPIt will be the CPI for March 2012 (the Reference Month), and CPIt-12 will be the CPI for March 2011 (which is the CPI for the twelfth month prior to the Reference Month). The CPI for March 2012 will be reported by the BLS and published on Bloomberg screen CPURNSA in April 2012, and the CPI for March 2011 was reported and published in April 2011.

For more information regarding the calculation of interest rates on the notes, including historical CPI levels and hypothetical interest rates, see “Historical Information and Hypothetical Interest Rate Calculations.”

If by 3:00 PM on any interest determination date the CPI is not published on Bloomberg screen CPURNSA for any relevant month, but has otherwise been published by the BLS, J.P. Morgan Securities LLC, in its capacity as the calculation agent, will determine the CPI as reported by the BLS for such month using such other source as on its face, after consultation with us, appears to accurately set forth the CPI as reported by the BLS.

In calculating CPIt and CPIt-12, the calculation agent will use the most recently available value of the CPI determined as described above on the applicable interest determination date, even if such value has been adjusted from a prior reported value for the relevant month. However, if a value of CPIt and CPIt-12 used by the calculation agent on any interest reset date to determine the interest rate on the notes (an “initial CPI”) is subsequently revised by the BLS, the calculation agent will continue to use the initial CPI, and the interest rate determined on such interest determination date will not be revised.

If the CPI is rebased to a different year or period and the 1982-1984 CPI is no longer used, the base reference period for the notes will continue to be the 1982-1984 reference period as long as the 1982-1984 CPI continues to be published.

If, while the notes are outstanding, the CPI is discontinued or substantially altered, as determined by the calculation agent in its sole discretion, the calculation agent will determine the interest rate on the notes by reference to the applicable substitute index that is chosen by the Secretary of the Treasury for the Department of The Treasury’s Inflation-Linked Treasuries as described at 62 Federal Register 846-874 (January 6, 1997) or, if no such securities are outstanding, the substitute index will be determined by the calculation agent in accordance with general market practice at the time; provided that the procedure for determining the resulting interest rate is administratively acceptable to the calculation agent.

All calculations with respect to the interest rate, as well as any successor or substitute rate calculation, will be rounded to the nearest one hundred-thousandth, with five one-millionths rounded upward (e.g., .876545 would be rounded to .87655); all dollar amounts related to the determination of the interest payment per $1,000 stated principal amount note on each interest payment date, at maturity, if any, will be rounded to the nearest ten-thousandth, with five one hundred-thousandths rounded upward (e.g., .76545 would be rounded up to .7655); and all dollar amounts paid on the aggregate stated principal amount of notes per holder will be rounded to the nearest cent, with one-half cent rounded upward.

Risk Factors

The following is a non-exhaustive list of certain key risk factors for investors in the notes. For further discussion of these and other risks, you should read the section entitled “Risk Factors” beginning on page PS-14 of the accompanying product supplement no. MS-13-A-I. We also urge you to consult your investment, legal, tax, accounting and other advisers before you invest in the notes.

instruments.” You generally will be required to accrue interest income in each year at a rate equal to our “comparable yield,” with adjustments to reflect the differences between the amounts of interest actually paid and the amounts set forth in the projected payment schedule, as described in the product supplement. Generally, amounts received at maturity or earlier sale or exchange in excess of your adjusted 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 your notes, which to that extent 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 their issue price should consult their tax advisers with respect to the tax consequences of an investment in notes, including the treatment of the difference, if any, between the basis in their notes and the notes’ adjusted issue price.

The discussion in the preceding paragraph, when read in combination with the section entitled “Certain U.S. Federal Income Tax Consequences” in the accompanying product supplement, constitutes the full opinion of Davis Polk & Wardwell LLP regarding the material U.S. federal income tax consequences of owning and disposing of notes.

Historical Information and Hypothetical Interest Rate Calculations

Provided below are historical levels of the CPI as reported by the BLS for the period from January 2002 to February 2011. Also provided below are the hypothetical interest rates for the period from January 2004 to April 2011 that would have resulted from the historical levels of the CPI presented below and a spread of 1.50% per annum. We obtained the historical information included below from Bloomberg Financial Markets and we make no representation or warranty as to the accuracy of completeness of the information so obtained from Bloomberg Financial Markets.

The historical levels of the CPI should not be taken as an indication of future levels of the CPI, and no assurance can be given as to the level of the CPI for any Reference Month. The hypothetical interest rates that follow are intended to illustrate the effect of general trends in the CPI on the amount of interest payable to you on the notes. However, the CPI may not increase or decrease over the term of the notes in accordance with any of the trends depicted by the historical information in the table below, and the size and frequency of any fluctuations in the CPI level over the term of the notes, which we refer to as the volatility of the CPI, may be significantly different than the volatility of the CPI indicated in the table. Additionally, for ease of presentation, the hypothetical interest rates set forth below have only been calculated to the fourth decimal point and rounded to the nearest third decimal point, which is different from the rounding convention applicable to the notes. As a result, the hypothetical interest rates depicted in the table below should not be taken as an indication of the actual interest rates that will be paid on the interest payment dates over the term of the notes.

The hypothetical interest rate payable on the notes for the February 28, 2005 interest payment period would have been 5.023% per annum. This hypothetical interest rate is calculated by inserting the following CPI levels into the interest rate formula described above under “Additional Provisions — Interest Rate”:

CPIt = 191.0, which is equal to the CPI level for November 2004, which is the second calendar month prior to the interest reset date of January 31, 2005, would be the reference month; and

CPIt-12 = 184.5, which is equal to the CPI level for November 2003, the twelfth calendar month prior to the reference month for the interest reset date of January 31, 2005

Interest Rate = [(191.0 – 184.5) / 184.5] + 1.50% = 5.023% per annum
