XShares Group Chairman and CEO Joseph L. Schocken to Ring NYSE Opening Bell

Joseph L. Schocken, chairman and CEO of XShares Group Inc., parent company of XShares Advisors LLC, a sponsor of innovative exchange-traded products (ETPs), will ring The Opening BellSM at the New York Stock Exchange today in recognition of the listing of the AirShares EU Carbon Allowances Fund (NYSE Arca: ASO). Launched on December 15, 2008, AirShares is the only exchange-traded equity product that provides access to the fast-growing EU carbon market.

“I’m honored to be part of the bell-ringing tradition at the New York Stock Exchange, especially to recognize AirShares’ listing. AirShares gives institutional and individual investors a chance to invest in the world’s fastest growing commodity, as well as address climate change through new capital markets tools like carbon credits,” said Mr. Schocken. “As the use of carbon credits grows in Europe and the U.S., we expect that the value of carbon vehicles like AirShares will be recognized by the global markets. We at XShares see long-term value in these opportunities and remain committed to bringing innovative exchange-traded products based on infrastructure and the environment to investors.”

The AirShares EU Carbon Allowances Fund is a pool of EU carbon credits that expire in 2009-2012, trades on the European Climate Exchange in London and is transferable under the European Union’s Emissions Trading Scheme (EU ETS). As contracts approach their December expiration, AirShares sells expiring contracts and replaces them with contracts with later expirations. ASO also seeks to hedge the currency risk associated with fluctuations in the Euro/U.S. dollar exchange rate. AirShares is a passively managed, equity product and does not track an index. Although the futures contracts held by AirShares and most of its assets are denominated in Euros, the shares trade in U.S. dollars.

Government-issued EU EUAs represent approximately two-thirds of the world’s carbon market, which doubled in value in 2008 to $90 billion, according to consulting firm Point Carbon.

Risk Considerations

To determine if this fund is an appropriate investment for you, please carefully consider the fund's investment objectives, risk factors and charges and expenses before investing. This and other information can be found in the fund's prospectus, which may be obtained by calling 1-800-925-2807 or visiting our website at www.xsharesadvisors.com/airshares/prospectus.Please read it carefully before investing.

Commodities and futures generally are volatile and may not be suitable for all investors.

Commodity trading is highly speculative and the underlying instruments determined by the methodology on which the fund’s trading will be based, are likely to be volatile and could suffer from periods of a prolonged decline in value.

The AirShares EU Carbon Allowances Fund is speculative and involves a high degree of risk. The market for European Union Allowances (EUAs) may be volatile and illiquid, which may adversely affect the value of the fund’s shares. An investor may lose all or substantially all of an investment in the fund. The fund is subject to fees and expenses and will be successful only if losses are avoided.

In addition to the normal risks of investing, foreign investing involves special risks, such as risk of loss from currency fluctuation or political or economic uncertainty. The trading activities of the fund will subject holders of AirShares to currency risk. European Climate Exchange CFI Futures Contracts and most of the assets of the fund will be denominated in Euros while the shares trade in U.S. dollars. Changes in the value of the euro relative to the U.S. dollar alone may cause the trading price of the shares to decline. Funds focusing on a single commodity generally experience greater price volatility than a diversified commodity pool.

If the member states of the European Union fail to adhere to their obligations under the Kyoto Protocol or the EU ETS, the value of the shares may be adversely affected. Depending upon the performance of the fund, including the interest rate environment and the amount of interest the fund earns on its fixed income securities, the expenses of the fund alone could result in losses to your investment.

Although the shares are intended to provide investment results that relate directly to the value of its long positions in futures contracts for EUAs, the value of the fund’s shares may diverge from the value of such long positions for various reasons. There is a risk that the calculation of the NAV of the fund will not accurately reflect the realizable market value of such futures contracts.

The fund has only a brief and limited operating and trading history on which to evaluate an investment in the shares.

The fund is not a mutual fund or any other type of investment company within the meaning of the Investment Company Act of 1940, as amended, and is not subject to regulation thereunder.

Shares of the fund are not FDIC insured, may lose value and have no bank guarantee. AirShares EU Carbon Allowances Fund is distributed by ALPS Distributors, Inc.

XShares Advisors LLC and ALPS Distributors, Inc. are unaffiliated entities.
