Camden National Corporation Listed on Russell 3000 Index and Small-Cap Russell 2000 Index - 7/5/2006

CAMDEN, Maine, July 5, 2006 - Camden National Corporation (AMEX: CAC; the "Company") was listed on the Russell 3000® Index and the small-cap Russell 2000® Index when the reconstitution of these indexes was published on June 30, 2006 by Russell Investment Group. Russell rebalances the Russell family of indexes annually to maintain indexes that are representative of the U.S. equity market.

Membership in the Russell 3000, which remains in place for one year, means automatic inclusion in the large-cap Russell 1000Ò Index or small-cap Russell 2000Ò Index as well as the appropriate growth and style indexes. Russell determines membership for its equity indexes primarily by objective, market capitalization rankings and style attributes.

"We are very pleased to continue to be part of the Russell 3000 and Russell 2000, as it broadens the exposure of Camden National Corporation's stock to the wide range of investors who make buying decisions based upon a company's inclusion in these industry-leading indexes," said Camden National Corporation President and Chief Executive Officer Robert W. Daigle.

Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for both passive and active investment strategies. An industry-leading $3.8 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.

Annual reconstitution of Russell indexes captures the 3,000 largest U.S. stocks as of the end of May, ranking them by total market capitalization to create the Russell 3000. The largest 1,000 companies in the ranking comprise the Russell 1000 while the remaining 2,000 companies become the widely used Russell 2000. These investment tools originated from Russell's multi-manager investment business in the early 1980s when the company saw the need for a more objective, market-driven set of benchmarks in order to evaluate outside investment managers.
