Opta Lehman Brothers Commodity Index (LBCI) Pure Beta Total Return ETN

FACT SHEET Created on March 18, 2008 | Page 2

The daily weighting of each commodity in the LBCI Pure Beta Total Return is a function of the liquidity in the futures contract for that commodity, determined annually and held constant thereafter, and the daily excess returns on the contract for that commodity in which the LBCI Pure Beta Total Return is then invested. The annual determination of contract liquidity is the same as used for purposes of annual target contract weighting in the general LBCI, with liquidity employed on the basis that the most actively-traded futures contracts may best convey recent production patterns and expectations of future production levels, commodity consumption and potential storage concerns.

For each commodity in the LBCI Pure Beta, an algorithm determines the particular futures contract in which to invest each quarter. This algorithm selects forward contracts for each commodity based on the contract month whose price most closely correlates to the average price for that commodity across all contract months in the 0- to 12-month measurement period, weighted by the total dollar amount (or “open interest”) invested in each month’s contract (and subject to certain minimum liquidity criteria).

The return of the LBCI Pure Beta Total Return reflects the returns of the underlying commodities futures contracts (including both price changes and “roll yields”), plus the interest return on hypothetical invested cash collateral.

For more details, please see the pricing supplement dated February 20, 2008, for the Opta ETN linked to the LBCI Pure Beta Total Return.

The S&P Listed Private Equity Index® Net Return is a global private equity index. The return of the index reflects the returns of the underlying company stock prices, plus dividends net of applicable withholding taxes. The index is passively managed; this means that index constituents are selected and weighted based on pre-determined rules. The index is designed to provide tradable exposure to the equity of leading publicly traded private equity companies. Index constituents are selected using both qualitative and quantitative criteria (size, liquidity, exposure and activity requirements). The index is then constructed using a liquidity-driven weighting scheme in an attempt to achieve liquidity in a section of the market that may have few highly liquid securities. The index is rebalanced semi-annually.
