Mac-Gray Corporation to Join Russell 3000(R) Index

WALTHAM, Mass., June 24 /PRNewswire-FirstCall/ -- Mac-Gray Corporation (NYSE:
TUC), the nation's premier provider of laundry facilities management services
to multi-unit housing locations, today announced that it is set to join the
broad-market Russell 3000(R) Index when Russell Investments reconstitutes its
comprehensive set of U.S. and global equity indexes on June 26, 2009 according
to a preliminary list of additions posted on www.russell.com.

"The Russell 3000 is one of the most widely known broad-market indices and
Mac-Gray's inclusion reflects our continued growth and our progress in
achieving the Company's strategic goals," said Stewart G. MacDonald,
Mac-Gray's chief executive officer. "Our addition should result in greater
investor awareness and interest in Mac-Gray."

Annual reconstitution of Russell's U.S. indexes captures the largest U.S.
stocks as of the end of May 2009, ranking them by total market capitalization.
Membership in the Russell 3000(R), which remains in place for one year, means
automatic inclusion in the large-cap Russell 1000(R) Index or small-cap
Russell 2000(R) Index as well as the appropriate growth and value style
indexes. The Russell 3000(R) also serves as the U.S. component to the Russell
Global Index, which Russell launched in 2007. Russell determines membership
for its equity indexes primarily by objective, market-capitalization rankings
and style attributes.

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 $4 trillion in assets currently are
benchmarked to them. 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.
