Item 3 is hereby amended and restated to read as follows:

The Shares purchased by Philotimo were purchased with working capital (which may, at any given time, include margin loans made by brokerage firms in the ordinary course of business) in open market transactions. The Shares purchased by KWM were purchased with the funds for the accounts of its customers (which may, at any given time, include margin loans made by brokerage firms in the ordinary course of business) in open market transactions. The Shares purchased by Mr. Kanen were purchased with personal funds (which may, at any given time, include margin loans made by brokerage firms in the ordinary course of business) in open market transactions. The aggregate purchase price of the 1,860,466 Shares beneficially owned by KWM is approximately $4,785,626, including brokerage commissions. The aggregate purchase price of the 300,000 Shares beneficially owned by Philotimo is approximately $714,460, including brokerage commissions. The aggregate purchase price of the 116,082 Shares beneficially owned by Mr. Kanen is approximately $268,290, including brokerage commissions.

Item 4 is hereby amended to add the following:

On March 23, 2018, KWM delivered a letter to the Issuer (the “Nomination Letter”) nominating a slate of four highly qualified director candidates, Anthony Ambrose, Alan B. Howe, David L. Kanen and Jeffrey S. Padnos (collectively, the “Nominees”), for election to the Board at the Issuer’s 2018 annual meeting of stockholders (the “Annual Meeting”). The Reporting Persons note that Issuer’s Amended and Restated Bylaws do not include advanced notice provisions for shareholder nominations of director candidates. The Reporting Persons believe that substantial change is required to the composition of the Issuer’s Board to ensure that the best interests of shareholders are paramount in the board room. The Reporting Persons believe that the nominees have the qualifications to not only serve as directors of the Issuer but to help ensure that the required steps are taken to put the Issuer on the right track towards shareholder value creation. The Reporting Persons hope to continue their constructive dialogue with the Issuer’s management team and Board regarding opportunities to unlock value at the Issuer, including changes to Board composition.
