Page 2 Overview - Liquid Alpha USD 5 TR is a multi-asset medium- to long-term investment strategy which gives access to a diversified pool of alpha generating assets using a dynamic allocation tool - The strategy has the objective to generate absolute non-directional returns, un-correlated to the traditional markets, through a combination of diversified proprietary alpha generating strategies from different asset classes. The Index has been live since April 23, 2008 - The allocation among the Underlying Indices occurs quarterly and is based on their returns, correlation and volatilities using a quantitative Mean Variance Optimizer model - The quantitative model combines the different sources of alpha and cash to generate an Index with a target volatility of 5% - Seeks to manage downside risk through a stop-loss mechanism which is triggered if the Index return over 60-business days is below 4% over any 3 consecutive days Performance Analysis Jan 99 -- Jul 09(1) Liquid Alpha HFRX Global iBoxx USD 5% USD TR Hedge Fund Index Treasury Growth over period 192.0% 9.4% 76.0% Annualised return 10.7% 1.4% 5.5% Volatility 4.3% 4.3% 5.0% Sharpe Ratio (3.65%) 1.71 - 0.44 0.43 Maximum drawdown -10.0% -25.2% -5.8% Drawdown recovery 9 Months 7 Months 2 Months Correlation versus: ------------------- HFRX Global Hedge Fund Index 0.46 1.00 -0.23 iBoxx USD Treasury TR Index -0.05 -0.23 1.00 Relative Performance: Jul 31, 2009(1) [GRAPHIC] Rolling 12 Month Volatility: Jan 00 -- Jul 09(1) [GRAPHIC] (1): Liquid Alpha USD TR 5 has been retrospectively calculated and did not exist prior to April 23, 2008.

Therefore, it has very limited performance history and no actual investment which allowed tracking of the performance of Liquid Alpha was possible before that date. AN INVESTMENT LINKED OR RELATED TO LIQUID ALPHA WILL NOT BE THE SAME AS AN INVESTMENT IN THE ALPHA INDICES -- The Liquid Alpha closing level on any trading day will depend on the performance of the 5 underlying index constituents (the "Alpha Indices"). The weighting of each Alpha Index is determined by an Optimized Asset Allocator ("OAA"), which seeks to maximize returns for a given level of volatility. You should, therefore, carefully consider the composition and calculation of each Alpha Index. THE ALPHA INDICES EXPOSE YOUR INVESTMENT TO EQUITY, COMMODITY, CURRENCY AND INTEREST RATE RISKS -- The Alpha Indices expose you to several asset classes and their respective risks, including risks relating to exchange rate fluctuations, foreign equity markets, commodity markets and emerging markets. In addition, the rates component is five times leveraged. To learn more about Liquid Alpha, see Underlying Supplement No. 15A/2 dated September 11, 2008 filed with the Securities and Exchange Commission. THE ALPHA INDICES ARE NOT EQUALLY WEIGHTED IN THE LIQUID ALPHA MODEL AND MAY OFFSET EACH OTHER -- The Alpha Indices are assigned different weightings in Liquid Alpha via an Optimized Asset Allocation Model. The same return generated by two Alpha Indices, whether positive or negative, may have a different effect on the performance of Liquid Alpha. Additionally, positive returns generated by one or more Alpha Index may be moderated or more than offset by smaller positive returns or negative returns generated by the other Alpha Indices. THE ACTUAL EXPERIENCED VOLATILITY OF EACH ALPHA INDEX AND LIQUID ALPHA MODEL MAY NOT EQUAL THE TARGET VOLATILITY, WHICH MAY HAVE A NEGATIVE IMPACT ON THE PERFORMANCE OF LIQUID ALPHA -- The weighting of each Alpha Index in the Liquid Alpha Model is adjusted to target a volatility level of 5%. Because this adjustment is based on the volatility of the previous 60 business days, the actual volatility realized on the Alpha Indices and the Liquid Alpha Model will not necessarily equal the volatility target. THE CALCULATION OF LIQUID ALPHA'S CLOSING LEVEL WILL INCLUDE A DEDUCTION OF COSTS FROM THE ALPHA INDICES -- On each trading day, the calculation of Liquid Alpha's closing level will include a deduction of costs from the Alpha Indices currently ranging between a minimum of 21 basis points per annum and maximum of 63 basis points per annum, depending on the individual weightings of the Alpha Indices.

Page 3 IMPORTANT INFORMATION Use of hypothetical information: Backtested, hypothetical or simulated performance results discussed herein have inherent limitations. Unlike an actual performance record based on actual client portfolios, simulated results are achieved by means of the retroactive application of a backtested model itself designed with the benefit of hindsight. Taking into account historical events the backtesting of performance also differs from actual account performance because an actual investment strategy may be adjusted any time, for any reason, including a response to material, economic or market factors. The backtested performance includes hypothetical results that do not reflect the reinvestment of dividends and other earnings or the deduction of advisory fees, brokerage or other commissions, and any other expenses that a client would have paid or actually paid. No representation is made that any trading strategy or account will or is likely to achieve profits or losses similar to those shown. Alternative modeling techniques or assumptions might produce significantly different results and prove to be more appropriate. Past hypothetical backtest results are neither an indicator nor guarantee of future returns. Actual results will vary, perhaps materially, from the analysis.
