A portion of the proceeds were used for the redemption of the preferred stock issued to the United States Department of Treasury in connection with the Company’s participation in the Small Business Lending Fund, as discussed below. The Purchase Agreements contain representations and warranties and covenants of the Company and the Investors that are customary in private placement transactions. The provisions of the Purchase Agreements also include an agreement by the Company to indemnify the Investors against certain liabilities. The Purchase Agreements required the Company to file a registration statement with the SEC to register for resale the 1,913,044 shares of common stock issued to the Investors in the Private Placement.

MVB issued 8,500 shares of $1,000 per share preferred stock with dividends payable in arrears on January 1, April 1, July 1 and October 1 each year. MVB's loan production qualified for the lowest dividend rate possible of 1%. MVB may continue to utilize the SBLF capital through March 8, 2016 at the 1% dividend rate. After that time, if the SBLF is not retired, the dividend rate increases to 9%. On January 5, 2017, the Company redeemed all of the 8,500 shares of its Senior Non-Cumulative Perpetual Preferred Stock, Series A, liquidation amount $1,000 per share (“Series A Preferred Stock”). The aggregate redemption price of the Series A Preferred Stock was $8,508,500, including dividends accrued, but unpaid through, but not including the redemption date. The Series A Preferred Stock was redeemed from the Company’s surplus capital and approved by the Company’s primary federal regulator.
