Depending upon overall market conditions, other investment opportunities available to the Reporting Persons, and the availability of securities of the Issuer at prices that would make the purchase or sale of such securities desirable, the Reporting Persons may endeavor (i) to increase or decrease their respective positions in the Issuer through, among other things, the purchase or sale of securities of the Issuer on the open market or in private transactions, including through a trading plan created under Rule 10b5-1(c) or otherwise, on such terms and at such times as the Reporting Persons may deem advisable and/or (ii) to enter into transactions that increase or hedge their economic exposure to the Common Stock without affecting their beneficial ownership of shares of Common Stock.

No Reporting Person has any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D except as set forth herein or such as would occur upon or in connection with completion of, or following, any of the actions discussed herein. The Reporting Persons may consider, explore and/or develop plans and/or make proposals with respect to, or with respect to potential changes in, the operations, management, the certificate of incorporation and bylaws, Board composition, ownership, capital or corporate structure, capital allocation, dividend policy, strategy and plans of the Issuer, potential strategic transactions involving the Issuer or certain of the Issuer's businesses or assets, or may change their intention with respect to any and all matters referred to in Item 4. The Reporting Persons intend to communicate with the Issuer's management and Board about a broad range of strategic and operational matters, including, without limitation, a sale of the Issuer or certain of its businesses or assets, in which the Reporting Persons may participate, as a means of enhancing shareholder value. The Reporting Persons intend to review their investment in the Issuer on a continuing basis and may from time to time in the future express their views to and/or meet with management, the Board, other shareholders or third parties, including, potential acquirers, service providers, advisers, and financing sources, and/or formulate plans or proposals regarding the Issuer, its assets or its securities.
