The S and P 500([R]) Daily RC2 8% Excess Return Index Performance Update - February 2012 OVERVIEW The S and P 500([R]) Daily 8% RC2 Excess Return Index (the "Index" or "S and P 500 Daily RC2") is intended to provide investors with exposure to broad U.S equities with the potential for greater stability and lower overall risk when compared to the S and P 500([R]) Total Return Index. Hypothetical and Actual Historical Performance (January 31, 2002 to January 31, 2012)[] 170.000 ------ S and P 500 Daily RC2 150.000 ------ S and P 500[R] Index 130.000 110.000 90.000 70.000 ------ ------ -------------- ------ ------ 50.000 Jan-02 Jan-04 Jan-06 Jan-08 Jan-10 Jan-12 Key Features of the Index Exposure to the S and P 500[R] Total Return Index with the overlay of risk control mechanism that targets an annualized volatility of 8% Ability to dynamically allocate exposure between the S and P 500([R]) Total Return Index and US government bond futures Exposure adjusted on a daily basis based on the historical volatilities and correlations between the S and P 500([R]) Total Return Index (the "Underlying Equity Index") and the S and P 10 Year Treasury Note Futures Index Total Return (the "Underlying Bond Index") Potential for enhanced returns compared with the first generation Risk Control Indices via an allocation in US government bond futures Levels published daily by Standard and Poor's on Bloomberg under the ticker SPX8UE2 Hypothetical Index Volatility and Leverage (July 01, 2002 to January 31, 2012)[] 80% 100% 80% 60% 60% 40% 40% Equity Exposure 20% 20% ========= ====================== ====== ================= ====== 0% 0% Jul-02 Jul-04 Jul-06 Jul-08 Jul-10 --------- ------ Equity exposure (right) S and P 500 Daily RC2 Target Volatility Recent Index Performance January 2012 December 2011 November 2011 ------------------------------- --------- -------------------- ---------------------------------- ----------------------------- -------------- Historical Return(2) 2.14% 1.26% 0.58% ------------------------------- --------- -------------------- -------------------- ------------- ----------------------------- -------------- Comparative Hypothetical and Historical Total Returns (%), Volatility (%) and Correlation -- January 31, 2012 Ten Year Ten Year One Year Three Year Five Year Annualized Annualized Ten Year Return(1) Annualized Return(1) Annualized Return(1) Return(1) Volatility(4) Sharpe Ratio(5) Correlation(4) ------------------------------- --------- -------------------- -------------------- ------------- ------------- --------------- -------------- S and P 500[R] RC2 8% Excess Return 4.3% 10.5% 3.2% 4.2% 8.1% 51.3% 100.0% Index ------------------------------- --------- -------------------- -------------------- ------------- ------------- --------------- -------------- S and P 500[R] Index 2.0% 16.7% -1.8% 1.5% 22.0% 6.8% 78.5% February 7, 2012

Notes (1) Represents the performance of the Index based on, as applicable to the relevant measurement period, the hypothetical backtested daily Index closing levels from January 31, 2002 through June 2, 2011, and the actual historical performance of the Index based on the daily Index closing level from June 3, 2011 through January 31, 2012, as well as the performance of the S and P 500[R] Index over the same period. For purposes of these examples, each index was set equal to 100 at the beginning of the relevant measurement period and returns calculated arithmetically (not compounded). There is no guarantee the Index will outperform the S and P 500[R] Index or any alternative investment strategy. Source: Bloomberg and JPMorgan. [] Calculated based on the annualized standard deviation for the ten year period prior to January 31, 2012. Past performance is not indicative of future returns. JJanuary (3) The historical volatility levels of the S and P 500[R] Index are presented for informational purposes only and have inherent limitations. For the purpose of this graph, volatility is calculated in accordance with Standard and Poor's official methodology used in the calculation of the S and P 500[R] RC2 Index. No representation is made that in the future the S and P 500[R] Index will have the volatility shown above. Alternative modeling techniques or assumptions might produce significantly different results and may prove to be more appropriate. The hypothetical equity exposure obtained from such back-testing should not be considered indicative of the actual exposure that would be assigned during your investment in the Index. No representation is made that the actual performance of the Index would result in exposure consistent with the hypothetical exposure displayed in the preceding graph. Actual annualized volatilities and exposures will vary, perhaps materially, from this analysis. Source: Bloomberg and JPMorgan. (4) Correlation is calculated from the historical returns, as applicable to the relevant measurement period, of the S and P 500[R] Index (the "Underlying Index") over a six-month observation period. Correlation refers to the degree that the S and P 500 RC2 8% Excess Return Index has changed relative to daily changes in the S and P 500 Index Index for the ten year period prior to January 31, 2012. (5) For the above analysis, the Sharpe Ratio, which is a measure of risk-adjusted performance, is computed as the ten year annualized historical return divided by the ten year annualized volatility. Key Risks The Index has a limited operating history and may perform in unexpected ways --the Index began publishing on June 3, 2011 and, therefore, has a limited history. S and P has calculated the returns that hypothetically might have been generated had the Index existed in the past, but those calculations are subject to many limitations and do not reflect actual trading, liquidity constraints, fees and other costs. The Index may not be successful, may not outperform either underlying index and may not achieve its target volatility --no assurance can be given that the volatility strategy will be successful or that the Index will outperform the Underlying Equity Index or the Underlying Bond Index or any alternative strategy that might be employed to reduce the level of risk of the Underlying Equity Index. We also can give you no assurance that the Index will achieve its target volatility of 8%. The Index may significantly underperform the Underlying Equity Index --the Index is designed to allocate its exposure between the Underlying Equity Index and the Underlying Bond Index in a manner that results in the Index targeting a volatility of 8%. It is not possible to predict the level of exposure that the Index will have to either the Underlying Equity Index or Underlying Bond Index over a given period of time. However the Index will likely have less, and possibly significantly less, than 100% exposure to the Underlying Equity Index over a period of time. Consequently, if the Underlying Equity Index increases in value over the applicable period, the Index will likely underperform the Underlying Equity Index, possibly significantly, over the same period if the Underlying Bond Index declines or does not increase in value to the same extent over that period. If the Underlying Equity Index and the Underlying Bond Index are negatively correlated and the Index has relatively high exposure to the Underlying Bond Index and relatively low exposure to the Underlying Equity Index, the Index may experience a significant negative performance even as the Underlying Equity Index rises. In certain circumstances, the Index will be notionally invested, in part, in cash, on which no interest or other return will accrue --in certain circumstances the Index will be solely allocated to the Underlying Equity Index with a weight less than 100% and with the balance notionally allocated to cash. No net return or interest will accrue on any such portion of the Index exposure that is notionally allocated to cash, and such portion may be significant. Such portion is effectively uninvested. The Index is subject to the negative impact of an interest deduction--because the Index is an excess return index, the level of the Index reflects the weighted returns of the Underlying Indices less an interest deduction, which is generally based on the return from a synthetic daily roling 3-month bond, with reference to the 2-month and 3-month U. S. LIBOR rates. As a result, the performance of the Index will be subject to the negative impact of those interest rates. Key Risks Continued The returns of the Underlying Indicies may offset each other or may become correlated in decline --at a time when the value of one Underlying Index increases, the value of the other Underlying Index may not increase as much or may even decline, offsetting the potentially positive effect of the performance of the former Underlying Index on the performance of the Index. Historically, the performance of the Underlying Equity Index has often been negatively correlated with the performance of the futures contracts underlying the Underlying Bond Index. It is also possible that the returns of the Underlying Indices may be positively correlated with each other. In this case, a decline in one Underlying Index would not moderate the effect of a decline in the other Underlying Index on the performance of the Index, but would rather exacerbate it. As a result, the Index may not perform as well as an alternative index that tracks only one Underlying Index. Our affiliate, J. P.
