VLLY Valley Bancorp

Valley Bancorp (Nasdaq: VLLY), the holding company for Valley Bank, joined the Russell Microcap(TM) Index when the Russell Investment Group reconstituted its family of U.S. indexes on June 24, 2005. This was announced in their recently posted membership list at www.russell.com/us/indexes. The Russell Microcap Index, which will be comprised of the smallest 1,000 securities in the small-cap Russell(R) 2000 Index plus the next 1,000 companies, is based on a ranking of all U.S. equities by market capitalization. This new index offers managers and other investors a comprehensive, unbiased barometer to compare their performance against the genuine microcap marketplace of stocks. "We are pleased to be included in this prestigious index," stated Barry L. Hulin, CEO and president of Valley Bancorp. "It is the result of a lot of hard work by many people associated with the company, and we hope it will increase our visibility in the marketplace and investor demand for our stock." Russell indexes are widely used by investment managers and institutional investors for index funds, and as benchmarks for both passive and active investment strategies. More than $2.5 trillion in assets currently are benchmarked to them. Investment managers who oversee these funds purchase shares of member stocks according to that company's weighting in the particular index. Companies slated for the Russell Microcap were ranked as of May 31 by total market capitalization and weighted based on free-float adjustment, an integral aspect of Russell index methodology. Free-float adjustment means stocks are weighted by their available market capitalization, which is calculated by multiplying the primary closing price by the available shares.

Russell manages more than $135 billion in assets and advises clients worldwide representing $2.3 trillion.
