WASHINGTONFIRST ANNOUNCES DEAL

TO ACQUIRE ALLIANCE BANKSHARES

RESTON, VA – May 3, 2012 – WashingtonFirst Bankshares, Inc. (OTCBB: WFBI) announced today that it has entered into an agreement to acquire Chantilly, Virginia – based Alliance Bankshares Corporation (NASDAQ: ABVA) for a combination of cash and stock valued at approximately $24.4 million, based on today’s closing price of WFBI common stock . This will be the fourth and largest acquisition for WashingtonFirst, which opened for business in 2004. In conjunction with the acquisition, WashingtonFirst has commitments for $20 million in additional equity capital from institutional investors, existing Board members, and other local investors.

“We are thrilled to be able to add Alliance’s valuable Northern Virginia franchise to our growing footprint in the Washington metropolitan area,” said Shaza Andersen, chief executive officer of WashingtonFirst. “The current management team at Alliance, led by Bill Doyle, has done a commendable job of restoring the bank to a sound condition, and we look forward to working with his team to carry our combined business to the next level.”

WashingtonFirst recently reported total assets of $608 million as of March 31, 2012, and first quarter net income of $705 thousand or $0.24 per common share. Alliance reported total assets of $506 million as of December 31, 2011, and a net loss of $6 million for the year. Management of Alliance attributed the loss primarily to a $5.3 million deferred tax asset valuation allowance and $1.2 million of expenses related to a merger agreement with Eagle Bancorp, Inc. that was terminated last year by mutual agreement.

“We believe we have found an excellent partner in WashingtonFirst,” said Don Fisher, Alliance’s chairman. “They have a proven track record of growth, profitability, and the ability to execute mergers and acquisitions, and we are confident that this merger will serve our shareholders, customers, and employees very well.” Upon completion of the merger, Fisher and two additional Alliance directors will join the Board of WashingtonFirst.

In the merger, shareholders of Alliance will receive, at their election, either 0.4435 shares of WFBI common stock or cash in the amount of $5.30 for each share of Alliance common stock owned, provided that no more than 20% of the Alliance common shares may elect to receive cash. If more than 20% of the Alliance common shares elect to receive cash, the cash elections will be subject to proration in accordance with the terms of the merger agreement. The stock component of the consideration is expected to represent a tax-free exchange. The aggregate purchase consideration represents 86% of Alliance’s reported book value as of December 31, 2011, and a premium of 19% above today’s closing price of Alliance shares. The consideration to be received by Alliance shareholders is subject to adjustment under certain circumstances based on a formula contained in the merger agreement. Please refer to the Form 8-K to be filed by Alliance for additional details regarding potential adjustments in the consideration to be received by shareholders of Alliance and other terms of the merger agreement.

The merger is expected to close in the fourth quarter of 2012, and has been approved by the boards of directors of WFBI and Alliance. Completion of the transaction is subject to approval of regulatory authorities, approval of the shareholders of both WFBI and Alliance, the consummation of a capital raising transaction by WFBI, and the satisfaction or waiver of conditions customary in transactions of this type. In connection with the transaction, WFBI will make application for the listing of its common shares on the NASDAQ.
