New ETF listings will bring the total number of PowerShares to 31

NEW YORK, October 26, 2005 - The American Stock Exchange® (Amex®) announced today the launch of eight new exchange traded funds from PowerShares Capital Management LLC.

The introduction of the eight new funds brings to 31 the total number of PowerShares currently listed on the Amex.  Options on the new ETFs will also be available for trading.

The new PowerShares ETFs are: PowerShares Lux Nanotech Portfolio (PXN); PowerShares Aerospace & Defense Portfolio (PPA); PowerShares Dynamic Building & Construction Portfolio (PKB); PowerShares Dynamic Energy Exploration & Production Portfolio (PXE); PowerShares Dynamic Insurance Portfolio (PIC); PowerShares Dynamic Oil & Gas Services Portfolio (PXJ); PowerShares Dynamic Retail Portfolio (PMR); PowerShares Dynamic Utilities Portfolio (PUI).

“The Amex is pleased to work once again with our good partners at PowerShare s. These funds are the latest example of PowerShares’ creativity, and are consistent with its track record for delivering innovative financial products to a demanding marketplace,” said Cliff Weber, Senior Vice President of the ETF Marketplace at the Amex.

“The launch of these 8 new portfolios brings the total number of PowerShares to 31, making us the second largest sponsor of ETFs in the Unites States,” said Bruce Bond, president of PowerShares Capital Management. “We believe these new PowerShares represent intelligent and precise exposure to select industry groups to which many investors seek access.”

The Amex owns and calculates the Intellidexes, on which six of the eight new ETFs are based, while the Nanotech and Aerospace portfolios will be based on third-party indexes. 

The six PowerShares funds based on Intellidexes are designed to replicate as closely as possible, the price and yield of the Industry Group Intellidex Indexes on which they are based. The Intellidex Indexes are modified equal dollar weighted indexes designed to objectively identify and select stocks from a particular market segment that have greater capital appreciation potential.

For the each of the Industry Group Intellidex Indexes, Revere Data LLC is the primary resource for identifying companies included in each customized industry group universe. Eligible companies are ranked quarterly, based on criteria including fundamentals, valuation, timeliness and risk factors, and 30 stocks are selected from each of the targeted industry universes based on their Intellidex model score.

The Lux Nanotech fund seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the Lux Nanotech Index (LUXNI), which is a modified equal dollar weighted index. The Defense fund will correspond generally to the price and yield performance, before fees and expenses, of The SPADE Defense Index (DXS), which is a modified market capitalization weighted index.
