This release, and the associated conference call, web cast, other written
materials, and statements management may make, may contain certain
forward-looking statements regarding the Company's prospective performance and
strategies within the meaning of Section 27A of the Securities Act of 1933, as
amended, and Section 21E of the Securities Exchange Act of 1934, as amended. The
Company intends such forward-looking statements to be covered by the safe harbor
provisions for forward-looking statements contained in the Private Securities
Litigation Reform Act of 1995, and is including this statement for purposes of
said safe harbor provisions.

Forward-looking statements, which are based on certain assumptions and describe
future plans, strategies, and expectations of the Company, are generally
identified by use of the words "plan," "believe," "expect," "intend,"
"anticipate," "estimate," "project," or other similar expressions. The Company's
ability to predict results or the actual effects of its plans and strategies is
inherently uncertain. Accordingly, actual results may differ materially from
anticipated results.

The following factors, among others, could cause the actual results of the
merger to differ materially from the expectations stated in this release and the
associated conference call and web cast: the ability of the companies to obtain
the required shareholder or regulatory approvals of the merger; the ability of
the companies to consummate the merger; the ability of Southern Financial to
timely complete its acquisition of Essex Bancorp, Inc.; the ability to
successfully integrate the companies following the merger; a materially adverse
change in the financial condition of either company; the ability to fully
realize the expected cost savings and revenues; and the ability to realize the
expected cost savings and revenues on a timely basis.

Other factors that could cause the actual results of the merger to differ
materially from current expectations include a change in economic conditions;
changes in interest rates, deposit flows, loan demand, real estate values, and
competition; changes in accounting principles, policies, or guidelines; changes
in legislation and regulation; and other economic, competitive, governmental,
regulatory, geopolitical, and technological factors affecting the companies'
operations, pricing, and services.

The Company undertakes no obligation to update these forward-looking statements
to reflect events or circumstances that occur after the date on which such
statements were made.
