The Reporting Persons continuously assess the Issuer’s business, financial condition, results of operations and prospects, general economic conditions, other developments and additional investment opportunities. Depending on such assessments, the Reporting Persons and/or their affiliates may acquire additional securities of the Issuer or may determine to sell or otherwise dispose of all or some of the Issuer’s securities in the open market, in privately negotiated transactions, in transactions directly with the Issuer or otherwise. Such actions will depend upon a variety of factors, including, without limitation, current and anticipated future trading prices, the financial condition, results of operations and prospects of the Issuer, alternative investment opportunities, general economic, financial market and industry conditions and other factors that the Reporting Persons and/or their affiliates may deem material to their investment decision.

Depending on various factors including, without limitation, the Issuer’s financial position and investment strategy, the price levels of the Common Stock, conditions in the securities markets and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, engaging in further communications with management of the Issuer and/or the Board, engaging in discussions with other shareholders of the Issuer and others about the Issuer and the Reporting Persons’ investment, making proposals to the Issuer concerning changes to the capitalization, ownership structure, Board structure (including Board composition) or operations of the Issuer or changing their intention with respect to any and all matters referred to in subparagraphs (a) through (j) of Item 4 of Schedule 13D.
