Purpose of Transaction.

The Reporting Persons purchased the Shares based on the Reporting Persons’ belief that the Shares, when purchased, were undervalued and represented an attractive investment opportunity. Depending upon overall market conditions, other investment opportunities available to the Reporting Persons, and the availability of Shares at prices that would make the purchase or sale of Shares desirable, the Reporting Persons may endeavor to increase or decrease their position in the Issuer through, among other things, the purchase or sale of Shares on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable.

On January 15, 2013, Starboard V&O Fund delivered a letter to the Issuer (the “Nomination Letter”) nominating Louis S. Massimo, Lee D. Meyer and Jeffrey C. Smith (the “Nominees”) for election to the Board at the 2013 annual meeting of shareholders (the “2013 Annual Meeting”). The Reporting Persons have engaged, and intend to continue to engage, in discussions with management and the Board of the Issuer regarding the nomination of directors at the 2013 Annual Meeting and the composition of the Issuer’s Board, generally.

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 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, 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, continuing to engage in communications with management and the Board, engaging in discussions with stockholders of the Issuer and others about the Issuer and the Reporting Persons’ investment, including in connection with the solicitation of proxies for the election of directors at the 2013 Annual Meeting, making recommendations or proposals to the Issuer concerning changes to the capitalization, corporate structure, ownership structure, board structure (including board composition) or operations of the Issuer, purchasing additional Shares, selling some or all of their Shares, engaging in short selling of or any hedging or similar transaction with respect to the Shares, or changing their intention with respect to any and all matters referred to in Item 4.

Pursuant to the Compensation Letter Agreements, each of Messrs. Massimo and Meyer agreed to use the after-tax proceeds from such compensation to acquire securities of the Issuer (the “Nominee Shares”) at such time that Messrs. Massimo and Meyer shall determine. If elected or appointed to serve as a director of the Board, each of Messrs. Massimo and Meyer agreed not to sell, transfer or otherwise dispose of any Nominee Shares within two years of their election or appointment as a director; provided, however, in the event that the Issuer enters into a business combination with a third party, each of Messrs.
