Item 4. Purpose of Transaction

The Reporting Persons originally acquired, and continue to hold, the Shares reported in this Schedule 13D for investment purposes. The Reporting Persons have had numerous constructive discussions with the Issuer’s management to express their views as to the Issuer’s business and its current strategies to enhance or maximize shareholder value. The Reporting Persons will continuously assess the Issuer’s business, financial condition, results of operations and prospects, general economic conditions, the securities markets in general and the Shares in particular, other developments and other investment opportunities. Depending on such assessments, the Reporting

Persons may acquire additional Shares or may determine to sell or otherwise dispose of all or some of the Shares presently held by the Reporting Persons in the open market or in private transactions. Such actions will depend upon a variety of factors, including, without limitation, current and anticipated future trading prices for the Shares, 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 Person may deem material to its investment decision.

Although the Reporting Persons had no plans or proposals at the time of their various purchases and do not have any particular plans or proposals at present, 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, Issuer’s board of directors, other shareholders or third parties, including, potential acquirers, service providers and financing sources, and/or formulate plans or proposals regarding the Issuer, its assets or its securities, and may take other steps seeking to bring about changes to increase shareholder value. Such proposals or positions may include one or more plans that relate to the Issuer’s business, management, capital structure and allocation, corporate governance, board composition and strategic alternatives and direction.
