For the purpose of the chart illustrated on page 1, each index was set equal to 100 on October 31, 2005. For calculations of recent performance table on page 1 and comparison of hypothetical and historical performance table on page 2 actual index levels have been used. There is no guarantee that Optimax will outperform the S&P GSCI[] or any alternative strategy. Source: Bloomberg and JPMorgan. (2) Calculated from the historical returns, as applicable to the relevant measurement period, of the indices using historical rolling daily returns. For any given day, represents the annualized volatility of each index's arithmetic daily returns for the 126-index day period preceding that day. The back-tested, hypothetical, historical annualized volatility has inherent limitations. These volatility results were achieved by means of a retroactive application of a back-tested volatility model designed with the benefit of hindsight. No representation is made that in the future the Index and the S&P GSCI[] will have the volatilities as shown above or that the Index will outperform any alternative investment strategy. Alternative modeling techniques or assumptions might produce significantly different results and may prove to be more appropriate. Actual annualized volatilities may vary materially from this analysis. Source: Bloomberg and JPMorgan. (3) On a monthly basis, J.P. Morgan Securities Ltd., or JPMSL, acting as the Index calculation agent, will rebalance the Index to take synthetic long and short positions in the Basket Constituents based on mathematical rules that govern the Index and track the returns of the synthetic portfolio above cash. The weights for each Basket Constituent will be adjusted to comply with certain allocation constraints, including constraints on individual Basket Constituents, as well as the individual sectors. The sum of the weights is zero. (4) Volatility and correlation are based on daily returns over the past ten years. Correlation refers to the degree the applicable index has changed relative to changes in the JPMorgan Optimax Market-Neutral Index. The Sharpe Ratio, which is a measure of risk-adjusted performance, is calculated as the annualized ten year return divided by the annualized ten year volatility. Key Risks [] There are risks associated with a momentum-based investment strategy. The Index may fail to realize gains that could occur from holding assets that have experienced price declines, but experience a sudden price spike thereafter. [] The Index may not be successful, may not outperform any alternative strategy related to the Basket Constituents, or may not achieve its target volatility of 5%. [] The investment strategy involves monthly rebalancing and maximum weighting caps applied to the Basket Constituents by sector and asset type. [] Changes in the value of the Basket Constituents may offset each other. [] The Index was established on May 6, 2008 and has a limited operating history [] The Index may perform poorly in non-trending 'choppy' markets characterized by short-term volatility. [] The reported level of the Index will include the deduction of a fee assessed at 0.96% per annum. [] The momentum strategy embedded in the Index may not outperform other strategies that do not rebalance monthly. [] The Index is not representative of a pure long-only commodities allocation and is not designed to replicate commodities markets. [] Commodities futures contracts are subject to uncertain legal and regulatory regimes that may adversely affect the timing and amount of your payment at maturity. [] Commodities prices may change unpredictably, affecting the Index in unforeseeable ways. [] If a negative weighting is assigned to a Basket Constituent, signifying a short position relative to such constituent, there is an unlimited loss exposure to such constituent and such exposure may result in a significant drop in the level of the Index.
