Item 4.

Purpose of Transaction

On March 24, 2016, TCP 2 entered into a Sales Plan (the “10b5-1 Plan”) with Cantor Fitzgerald & Co. (“Cantor”) that is intended to comply with the requirements of Rule 10b5-1(c) promulgated under the Act. Pursuant to the 10b5-1 Plan, TCP 2 has directed Cantor to seek to dispose of up to 300,000 shares of Common Stock held by TCP 2 between April 25, 2016 and February 16, 2017. Transactions under the 10b5-1 Plan are subject to certain price restrictions and TCP 2 may terminate the 10b5-1 Plan at any time. See Item 6.A. below.

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, TM, 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.

As discussed in this Schedule 13D, the Reporting Persons own approximately 62.4% 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 non-executive Chairman of the 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 or any of its subsidiaries; (c) a sale or transfer of a material amount of assets of the Company or any of its subsidiaries; (d) any change in the present Board of Directors or management of the Company, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the Board; (e) any material change in the present capitalization or dividend policy of the Company; (f) any other material change in the Company’s business or corporate structure; (g) changes in the Company’s charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Company by any person; (h) causing a class of securities of the Company to be delisted from a national securities exchange, if any, or cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (i) a class of equity securities of the Company becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Securities Act, or (j) any action similar to any of those enumerated in items (a) through (i) above.
