These discussions may involve options for enhancing stockholder value through changes in corporate governance; specifically, declassifying the Issuer’s current staggered board of directors (the “Board”) at the next annual meeting with all of the current directors resigning and running for a one-year term; restructuring the committees of the Board; permitting shareholders owning 10% or more of the Issuer’s stock to call special meetings of shareholders; and other measures that would facilitate greater shareholder input on corporate matters.

The Reporting Persons intend to review their investment in the Issuer on a continuing basis and may from time to time and at any time in the future depending on various factors, including, without limitation, the Issuer’s financial position and strategic direction, actions taken by the Issuer’s Board, price levels of the Common Stock, other investment opportunities available to the Reporting Persons, conditions in the securities market and general economic and industry conditions, take such actions with respect to their investments in the Issuer as they deem appropriate. These actions may include, without limitation: (i) acquiring additional Common Stock and/or other equity, debt, notes, other securities, or derivative or other instruments that are convertible into Common Stock, or are based upon or relate to the value of the Common Stock or the Issuer (collectively, “Securities”) in the open market or otherwise; (ii) disposing of any or all of their Securities in the open market or otherwise; (iii) engaging in any hedging or similar transactions with respect to the Securities; or (iv) proposing or considering one or more of the actions described in subsections (a) through (j) of Item 4 of Schedule 13D.
