Dynex Capital, Inc.Set to Join Russell 3000 Index

GLEN ALLEN, Va.--(Business Wire)--
Dynex Capital, Inc. (NYSE:DX) today announced that it anticipates being added to
the broad-market Russell 3000 Index based upon preliminary disclosures by the
Russell Investment Group ("Russell"). The official inclusion is planned to occur
when Russell reconstitutes its comprehensive set of U.S. and global equity
indexes today, Friday, June 26, 2009. Russell determines membership for its
equity indexes primarily by objective market-capitalization rankings and style
attributes.

The 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 are currently
benchmarked to them. These investment tools originated from Russell's
multi-manager investment business in the early 1980's when the company saw the
need for a more objective, market-driven set of benchmarks in order to evaluate
outside investment managers.

Dynex Capital, Inc. is a specialty finance company that elects to be treated as
a real estate investment trust (REIT) for federal income tax purposes.
