 share equal to the acquiring person’s cost. Virginia law grants appraisal rights to any shareholder who objects to a control
share acquisition that is approved by a vote of disinterested shareholders and that gives the acquiring person control of a majority of the corporation’s voting shares. This regulation was designed to deter certain takeovers of Virginia public
corporations.

We have opted out of the Virginia anti-takeover law regulating “affiliated transactions.” Under this law, certain
material transactions between a Virginia corporation and any holder of more than 10% of any class of its outstanding voting shares are required to be approved by the holders of at least two-thirds of the
remaining voting shares, unless the articles of incorporation or bylaws of the corporation provide that this regulation does not apply. Affiliated transactions subject to this approval requirement include mergers, share exchanges, material
dispositions of corporate assets not in the ordinary course of business, any dissolution of the corporation proposed by or on behalf of a 10% holder or any reclassification, including reverse stock splits, recapitalization or merger of the
corporation with its subsidiaries, that increases the percentage of voting shares owned beneficially by a 10% holder by more than five percent.

Item 2. Exhibits.

In accordance with the
