             PROVIDENT BANKSHARES CORPORATION AND SOUTHERN FINANCIAL
                    BANCORP, INC. ANNOUNCE STRATEGIC MERGER

               *  Strengthens Commercial Market Position in Metro
               Washington and Northern Virginia
               *  Extends Presence into Central and Eastern Virginia

BALTIMORE: (November 3, 2003) - Provident Bankshares Corporation (NASDAQ: PBKS),
the parent company of Provident Bank, the second largest independent commercial
bank headquartered in Maryland, and Southern Financial Bancorp, Inc., (NASDAQ:
SFFB), the parent company of Southern Financial Bank, announced today the
signing of a definitive agreement for Southern Financial Bancorp to be merged
into Provident Bankshares Corporation.

         The merger reflects Provident's clearly defined business strategies
that include expansion into the Metro Washington area. Provident first entered
that region as a result of a merger with First Citizens Financial Corporation.
That transaction added 15 branches to Provident's network and a solid presence
in Washington's Maryland suburbs. Currently, Provident operates 116 offices
including both traditional and in-store locations. The bank has 50 branches in
Metro Washington and 66 in the Baltimore area. Provident's network now stretches
from Baltimore into Frederick, Montgomery and Prince George's Counties of
Maryland as well as into Northern Virginia and southern Pennsylvania.

         Southern Financial Bank, based in Warrenton, Virginia, was founded in
1986. It is the largest Virginia based bank operating in the Commonwealth's most
attractive markets. Southern Financial will have $1.5 billion in assets and
operate 33 offices following its acquisition of Essex Bancorp, Inc. which is
expected to close in the first quarter of 2004. Including Essex, the bank has
branches in the fast growing Northern Virginia areas of Fairfax, Loudoun and
Prince William Counties as well as Richmond, Charlottesville and the Tidewater
areas. Southern Financial is a leading SBA lender with a strong business banking
focus. In July of 2003, Southern was ranked 12th on Fortune Small Business' list
of America's Fastest Growing Small Companies.

         Provident Bankshares Corporation Chairman and Chief Executive Officer
Gary N. Geisel called the merger an "excellent fit" for both companies. "We've
been looking for the right strategic fit for us in Northern Virginia for over
three years and with Southern Financial, I'm certain we found that
fit--strategically, culturally and financially. Strategically, we extend our
reach into Northern Virginia and add Southern Financial's strong business
banking focus to our core competency, consumer banking. Culturally, both
organizations pursue strong commitments to our customers, our employees and the
communities we serve. And financially, we see opportunities to accelerate the
improvement in our balance sheet fundamentals and provide long-term shareholder
value.

         Southern Financial Bancorp Chairman and Chief Executive Officer Georgia
S. Derrico said, "We believe that Southern Financial and its core of dedicated
employees have built a unique institution focused on small and middle market
customers. Our goal has been to provide every credit and non-credit banking
service which any middle-market business could conceivably require. That has
been the engine of our growth. Provident will continue to support that focus. In
addition, our strategic partnership with Provident will bring an expanded
product base and a vastly more sophisticated marketing capability to our retail
branch system. Combining our commercial banking business with Provident's superb
retail base will create a Mid-Atlantic powerhouse.

         Since I founded this company in 1986, I have always focused on the best
interest of our shareholders and this merger agreement continues that emphasis.
For our customers and employees, this represents a new chapter - but one we
believe will fuel personal growth for our employees and business growth for our
customers."

Terms of the Merger

         Under the terms of this $330 million transaction, shareholders of
Southern Financial will receive 1.0875 shares of Provident common stock and
$11.125 in cash for each Southern Financial share held. Based upon the stated
value of $44.50 the price represents 272% of pro forma book value and 19.0x 2004
Earnings Per Share per First Call. The merger, which is subject to regulatory
and shareholder approval, is expected to be completed in the second quarter of
2004. In the first full year of operation, Provident expects the Southern
Financial transaction to be accretive to GAAP earnings and neutral to tangible
capital.

Provident/Southern: A Strategic Partnership

         Provident Bankshares Corporation Chairman and Chief Executive Officer
Gary N. Geisel added, "We have consistently commented that further expansion
into the Metro Washington market and enhanced commercial business operations
were key business strategies for Provident. This merger not only extends
Provident's presence in these attractive markets but it also provides Southern
Financial customers with more options and convenience for all of their banking
needs.At the same time, Southern Financial's established business banking
relationships will play a key role in our plans to boost Provident's commercial
presence in this growing, vibrant region. We are confident that the combined
organization will provide an outstanding sales and service experience for our
customers, a rewarding environment for our employees and superior long term
returns for our shareholders."
