Item 4.

PURPOSE OF TRANSACTION

The Reporting Persons initially acquired beneficial ownership of the Common Stock of the Issuer for investment purposes because they believed the Issuer's Common Stock represented an attractive investment opportunity.  The Reporting Persons have become increasingly concerned about the underperformance of the Common Stock relative to its peer group and the market, the Issuer's problems experienced with achieving various aspects of its strategic plan and its declining market share.  The Reporting Persons have substantial experience in the Issuer’s lines of business and have had constructive discussions with the Issuer's management.  The Reporting Persons believe they have valuable insights to contribute to the development of the business and intend to have further discussions with management, the Board of Directors of the Issuer, other shareholders of the Issuer and other relevant parties relating to the Issuer's business, operations, strategy, future plans, corporate governance and related matters. Depending upon, among other things, the outcome of the discussions referenced above, current and anticipated future trading prices for the shares of Common Stock, the financial condition, results of operations and prospects of the Issuer and its businesses, other investment opportunities available to the Reporting Persons, conditions in the securities markets, general economic conditions and other factors that the Reporting Persons deem relevant, the Reporting Persons may from time to time acquire additional shares of Common Stock or sell shares of Common Stock in the open market, in privately negotiated transactions or otherwise, and may take such other actions with respect to their investment in the Issuer as they may deem appropriate, including, without limitation, changing their intention with respect to any of the matters enumerated in clauses (a) through (j) of Item 4 of Schedule 13D.
