Item 4.                                 Purpose of Transaction

In the past 60 days, TCP 2 has purchased a total of 21,525 shares of Common Stock in the transactions described in the table below.

On September 30, 2015, TOA voluntarily transferred 591,443 shares of Common Stock to TA. As of the date hereof, TOA no longer owns any shares of Common Stock of the Issuer.

The Reporting Persons acquired their shares of Common Stock for investment purposes and in the ordinary course of business.  All of the Reporting Persons may dispose of securities of the Company at any time and from time to time in the open market, through dispositions in kind to parties holding an ownership interest in TCP, TP, TA and/or TCP 2, or otherwise.  In addition, the Reporting Persons may obtain securities of the Company through open market purchases, transfers from other Reporting Persons or otherwise.

The Reporting Persons own approximately 62.2% of the Company’s outstanding Common Stock and can control the Company’s affairs, including (i) the election of directors who in turn appoint management, (ii) any action requiring the approval of the holders of Common Stock, including adoption of amendments to the Company’s corporate charter, and (iii) approval of a merger or sale of all or substantially all assets. The Reporting Persons can also control certain decisions affecting the Company’s capital structure.

David B. Gendell, the brother of Jeffrey L. Gendell and an employee of an affiliate of the Reporting Persons, has served as a member of the Company’s Board of Directors since February 2012 and has served as the non-executive Chairman of the Company’s Board of Directors since January 2015.  While serving in such capacity, Mr. Gendell may have the ability to affect the composition of the Company’s management and influence the business operations of the Company or extraordinary transactions outside the normal course of the Company’s business.  If the Reporting Persons dispose of all or a portion of their holdings in the Company, they may not retain sufficient voting power to cause Mr. Gendell to continue to be a director.

Although the foregoing represents the range of activities presently contemplated by the Reporting Persons with respect to the Company, it should be noted that the possible activities of the Reporting Persons are subject to change at any time.  Accordingly, the Reporting Persons reserve the right to change their plans or intentions and to take any and all actions that they may deem to be in their best interests.

Except as set forth in the Schedule 13D, the Reporting Persons do not have any current intention, plan or proposal with respect to: (a) the acquisition by any person of additional securities of the Company, or the disposition of securities of the Company; (b) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Company
