EXPLANATORY NOTE

This Post-Effective Amendment No. 1 relates to the following Registration Statements on Form S-8 (collectively, the “Registration Statements”):

• Registration Statement No. 333-181520 registering 1,000,000 shares of StellarOne Corporation common stock in connection with the StellarOne Corporation Stock and Incentive Compensation Plan; and

• Registration Statement No. 333-83410 registering 750,000 shares of StellarOne Corporation common stock in connection with the StellarOne Corporation (formerly Virginia Financial Group, Inc.) Stock Incentive Plan.

On January 1, 2014, pursuant to the Agreement and Plan of Reorganization, dated as of June 9, 2013, between Union First Market Bankshares Corporation (“Union”) and StellarOne Corporation (“StellarOne”), and a related Plan of Merger, StellarOne merged with and into Union (the “Merger”). As a result of the Merger, StellarOne ceased to exist as of January 1, 2014.

Upon the completion of the Merger, each outstanding share of StellarOne common stock was converted into the right to receive 0.9739 shares of Union common stock. Shares of StellarOne common stock are no longer quoted on the NASDAQ Stock Market.

As a result of the Merger, StellarOne has terminated all offerings of securities pursuant to the Registration Statements. In accordance with the undertakings made by StellarOne in the Registration Statements to remove from registration by means of a post-effective amendment any of its securities being registered under the Registration Statements that remain unsold at the termination of the offering, Union (as successor to StellarOne) hereby terminates the effectiveness of the Registration Statements and deregisters any and all shares of StellarOne common stock originally reserved for issuance under the plans covered by the Registration Statements and registered under the Registration Statements, which remain unsold or unissued as of the date hereof.
