Capital Purchase Program and Stock Warrant

Capital Purchase Program and Stock Warrant

On January 30, 2009, as part of the Capital Purchase Program established by the U.S. Department of the Treasury (the “Treasury”) under the Emergency Economic Stabilization Act of 2008, the Company entered into a Letter Agreement and Securities Purchase Agreement—Standard Terms (collectively, the “Purchase Agreement”) with the Treasury, pursuant to which the Company sold (i) 22,000 shares of Fixed Rate Cumulative Perpetual Preferred Stock, Series A, par value $2.50 per share, having a liquidation preference of $1,000 per share (the “Preferred Stock”) and (ii) a warrant (the “Warrant”) to purchase 208,202 shares of the Company’s common stock, par value $2.50 per share, at an initial exercise price of $15.85 per share. As a result of the completion of a public stock offering in 2009, the number of shares of common stock underlying the Warrant was reduced by one-half to 104,101 and the Company redeemed all 22,000 shares of Preferred Stock pursuant to the Purchase Agreement. During 2011, the Warrant was sold by the U.S. Treasury at public auction and has not been exercised as of December 31, 2015.
