About the Ocean Tomo 300[TM] Patent Index

Recognized by The American Stock Exchange (www.amex.com) as "the first major, broad-based market equity index to be launched in 35 years," the Ocean Tomo 300[TM] Patent Index is a diversified market-weighted index of 300 companies that own the most valuable patents relative to their book value. Over a 10-year time period ending October 2006, the Ocean Tomo 300[TM] Patent Index outperformed the S&P 500 by more than 300 basis points annualized. The Index selection methodology identifies six companies within each of 50 size and style groups, reflecting a broad spectrum of market capitalizations and investment styles, including value, relative value, blend, growth at a reasonable price (GARP) and growth by decile, that have the highest ratio of patent value to book value.

The analytical engine used to evaluate the value of each company's patent portfolio is Ocean Tomo's PatentRatings(TM) software, which calculates the relative attractiveness of the more than four million patents issued by the U.S. Patent and Trademark Office since 1983, and which is widely recognized by the intellectual property valuation industry. Further details on the Index, its methodology, as well as a complete list companies in the Index and other materials are available at www.OceanTomoIndexes.com.
