Invesco PowerShares to List MENA Frontier Countries ETF on NASDAQ

Market Wire, July, 2008

Micro-Capitalization Company Risk Information

Investments in securities of micro-capitalization companies involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations.

Non-Diversified Fund & Industry Risk Information

The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund. The economies of frontier country markets are less developed and can be overly reliant on particular industries. It is likely that a substantial number of stocks included in the Underlying Index for certain of the MENA frontier countries will be securities of banks and other financial institutions. When a Fund is focused in a specific industry or sector, it presents greater risks than if it were broadly diversified over numerous industries and sectors of the economy. Please read the prospectus for a summary of these risks pertaining to each industry or sector.

Tax Consequences of Redemption Proceeds Being Limited Primarily to Cash Risk Information

Unlike most exchange-traded funds, the Fund does not and currently intends to make primarily in-kind redemptions. As such the Fund may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. Generally, this will cause the Fund to recognize gain it might not otherwise have recognized, or to recognize such gain sooner than would otherwise be required, if it were able to distribute the shares primarily in-kind. Based on the U.S. federal income tax rules applicable to the fund and an investment in the Fund, this may cause particular shareholders to be subject to tax on gains they would not otherwise be subject to, or at an earlier date than, if they had made an investment in a different exchange-traded fund.

Participation Notes ("P-notes") and their Risks

The Fund initially expects to invest up to 20% of its net assets in P-notes in seeking to track the performance of Kuwaiti securities included in the Underlying Index.

P-notes generally are issued by banks or broker-dealers and are promissory notes that are designed to offer a return linked to the performance of a particular underlying equity security or market. The return on a P-note that is linked to a particular underlying security generally is increased to the extent of any dividends paid in connection with the underlying security. However, the holder of a P-note typically does not receive voting rights as it would if it directly owned the underlying security. P-notes constitute direct, general and unsecured contractual obligations of the banks or broker-dealers that issue them, which therefore subjects the Fund to counterparty risk, as discussed below.
