Exchange National Bancshares To Be Included in the New Russell Microcap Index

Exchange National Bancshares (NASDAQ: EXJF) of Jefferson
City, MO, a financial services company, announced today it has been
selected for inclusion in the newly launched Russell Microcap(TM)
Index.
   The Russell Microcap(TM) Index is comprised of the smallest 1,000
securities in the small-cap Russell 2000(TM) Index plus the next 1,000
companies and 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.
   Companies selected for the Russell Microcap Index were ranked as
of June 24 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.
   James E. Smith, Chairman and CEO, stated, "We are pleased to be
included in the Russell Microcap Index and we look forward to the
broadened investor awareness that may result."
   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.
