As previously reported, the Reporting Persons intend to review their investment in the Issuer on a continuing basis. Depending on various factors including, without limitation, the Issuer's financial position and investment strategy, the price levels of the shares of Common Stock, conditions in the securities markets and general economic and industry conditions, the Reporting Persons intend to continue to consider, explore and/or develop plans and may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, engaging in communications with the Issuer's management and the Board, engaging in discussions with shareholders of the Issuer and others about the Issuer and the Reporting Persons' investment, making proposals to the Issuer concerning strategic transactions, including business combinations, a sale of the Issuer as a whole or in parts or acquisitions or investments by the Issuer, changes to the capital allocation strategy, capitalization, ownership structure, Board structure (including Board composition), operations of the Issuer, purchasing additional shares of Common Stock, selling some or all of their shares of Common Stock, engaging in short selling of or any hedging or similar transaction with respect to the shares of Common Stock, or take any other actions with respect to their investment in the Issuer permitted by law, including any or all of the actions set forth in paragraphs (a) - (j) of Item 4 of Schedule 13D.
