Maine & Maritimes Corporation Added to Russell Microcap Index

Maine & Maritimes Corporation (AMEX: MAM) today announced it has been added to the Russell Microcap Index after the Russell Investment Group reconstituted its comprehensive set of U.S. and global equity indexes on June 27, 2008.

Russell indexes are widely used by investment managers and institutional investors for both index funds and as benchmarks for passive and active investment strategies. The Company will hold its membership until Russell reconstitutes its indexes in June 2009.

"Russell is an industry leader for stock indexes, and we expect our inclusion will generate greater interest in our stock among institutional investors."
