NEW YORK, Aug. 23, 2007 — Dow Jones Indexes, a leading global index provider, today announced the results of the regular annual review of the Dow Jones Select MicroCap Index, which tracks the performance of U.S. microcap companies listed at the New York Stock Exchange (NYSE), American Stock Exchange (AMEX) and NASDAQ Stock Exchange (NASDAQ). The changes will be effective as of the open of trading on Monday, August 27, 2007.

After completion of the annual review, the number of components in the Dow Jones Select MicroCap Index will be 250 stocks, with 144 additions and 170 deletions.

The top five components by free-float market capitalization that will be added to the index are: NBT Bancorp Inc. (Financial Services; NBTB); PrivateBancorp Inc. (Financial Services; PVTB), Alliance One International Inc. (Consumer Goods; AOI), Bank Mutual Corp. (Financial Services; BKMU) and American States Water Co. (Utilities; AWR).

The Dow Jones Select MicroCap Index was created to provide market participants with an accurate and reliable measure of the U.S. microcap segment. The index serves as the underlying for an exchange-traded fund (ETF).

The initial stock selection pool is determined by ranking all NYSE stocks by full-market capitalization into 10 equal-numbered deciles, with deciles nine and 10 defining the microcap size range. Issues then are added from the AMEX and NASDAQ exchanges that fit this size range. Securities are then screened by market capitalization and by trading liquidity criteria, followed by further fundamental screens such as price/earnings ratio, price/sales ratio, profit change, operating margin and performance return screens.

The Dow Jones Select MicroCap Index components, weightings and daily closing values are available on the Dow Jones Indexes Web site at www.djindexes.com/mdsidx/?event=microcap.

Company additions to and deletions from the Dow Jones Select MicroCap Index do not in any way reflect an opinion on the investment merits of the company.
