FAIRFAX, Va., Feb. 4, 2013

FAIRFAX, Va., Feb. 4, 2013 /PRNewswire/ -- MainStreet Bank (OTC Bulletin
Board: MNSB) reported a profitable 2012 after expending diligent efforts to
return its loan portfolio to historically strong levels. This marks the fifth
consecutive year of profitability for MainStreet Bank.

"Loan quality was a significant focus in 2012. The effects of the economy
caught up to a few of our borrowers at the end of 2011 – which increased our
nonperforming numbers," reported Chairman, CEO and President Jeff W. Dick.
"After a year of concerted efforts working with our borrowers and in a few
cases writing down assets, I am happy to report that our asset quality is once
again strong. Nonperforming loans now represent a nominal one-third of one
percent of our loan portfolio."

The Bank originated $65 million in new commercial loans this year, with gross
loans ending the year at $215 million. The bank's balance sheet reflects total
assets at $271 million. Total deposits are at $241 million and the bank
remains well capitalized. The year-end book value per share is $9.73. The
share price on December 31, 2012 closed at 60% of book value, or $5.80.
