UNION BANKSHARES CORPORATION ANNOUNCES

REPAYMENT TO THE U. S. TREASURY

FOR IMMEDIATE RELEASE (Bowling Green, Virginia) — Union Bankshares Corporation (the “Company”) (NASDAQ: UBSH – News) announced it has redeemed the Preferred Stock issued to the United States Department of the Treasury (the “Treasury”) by repaying the $59 million it received in December 2008 under the Capital Purchase Program (“CPP”), which was created in the fall of 2008 under the federal Troubled Asset Relief Program.

“Our banks have been well capitalized throughout the time we have participated in the CPP. Additionally, the Company’s recent qualified equity offering that netted $59 million in mid-September will provide for any future growth opportunities. We are delighted that our regulators approved the Company’s redemption of the CPP investment, which we believe is in the best interests of our shareholders,” said G. William Beale, the Company’s President and CEO.

The Company plans to initiate discussions with the Treasury for the repurchase of the common stock purchase warrant issued to the Treasury in December 2008; that warrant, initially exercisable for 422,636 shares of UBSH’s common stock, was reduced by 50% to 211,318 shares of UBSH’s common stock after the Company’s successful completion of its qualified public offering in accordance with the terms of the warrant. The Company has 15 days from today’s repurchase date to determine if it will offer to repurchase the common share warrant issued to the Treasury or allow the Treasury to liquidate the warrant in the open market. Any adjustments to earnings resulting from the repayment of the preferred stock and/or repurchase of the warrant will be reflected upon settlement.
