About the Halter USX China Index

The Index, created by the Halter Financial Group and calculated and distributed
by the NYSE Arca, is comprised of companies whose common stock is publicly traded
in the United States and the majority of whose business is conducted within the
People's Republic of China. The Halter USX China Index was created in response to
the unique economic opportunities taking place in China, as well as the current
dynamics in the United States capital markets. While there is strong demand for
Chinese equity, U.S. investors still seek and prefer the transparency offered
with a U.S. listing. For a company to be included in the Halter USX China Index
it must conduct a majority of its business in China, maintain an average market
cap of over $50 million for the preceding 40 trading days, trade on the NYSE,
NYSE Amex or NASDAQ and be approved by USX Selection Committee. Investors can
gain exposure to the Index by investing in an exchange-traded fund (ETF), the
PowerShares Golden Dragon Halter USX China Portfolio (nyse arca:PGJ). For more
