Item 4.           Purpose of Transaction

Item 4 of the Schedule 13D is hereby amended and supplemented with the following:

On January 25, 2017, the Reporting Persons entered into a letter agreement (the “Letter Agreement”) with the Issuer and, solely for the limited purposes stated therein, Michael T. Popejoy and Michael Frantz (together, the “TRT Nominees”).  Under the terms of the Letter Agreement, the Issuer agreed to appoint Michael T. Popejoy to the Issuer’s Board of Directors (the “Board”) and to take all necessary actions to nominate the TRT Nominees for election to the Board at the Issuer’s 2017 annual meeting of shareholders (the “2017 Annual Meeting”), including, without limitation, nominating, recommending, and including in the Issuer’s proxy statement the TRT Nominees for election as directors of the Issuer at the 2017 Annual Meeting. The Letter Agreement also provides that the Issuer will not increase the size of the Board to more than seven members prior to the 2017 Annual Meeting.  Pursuant to the Letter Agreement at least one of the TRT Nominees will serve on each of the Board’s Compensation and Executive Committees until at least the Issuer’s 2018 annual meeting of shareholders (the “2018 Annual Meeting”), and Mr. Popejoy was appointed to the Board’s Compensation Committee and Mr. Frantz was appointed to the Board’s Executive Committee. If the Reporting Persons and their affiliates beneficially own less than 10% of the outstanding shares of Common Stock, but 5% or more of the outstanding shares of Common Stock, then the Reporting Persons will be entitled to representation on the Board of just one TRT Nominee. If the Reporting Persons and their affiliates beneficially own less than 5% of the outstanding shares of Common Stock, then the Reporting Persons will not be entitled to any representation on the Board.

Pursuant to the Letter Agreement, the Reporting Persons also agreed to certain restrictions that generally remain in effect until the 2017 Annual Meeting, including, among other things, not to (1) propose any shareholder proposal or seek the nomination of any candidate as a director of the Issuer at the 2017 Annual Meeting (other than the TRT Nominees), (2) solicit shareholders of the Issuer with respect to the approval of any shareholder proposal or the nomination or election of any candidate as a director of the Issuer in opposition to the recommendation of the Board, and (3) call or seek to have called any special meeting of shareholders of the Issuer.

The Letter Agreement further provides that the Reporting Persons will vote all shares of Common Stock that they are entitled to vote at the 2017 Annual Meeting as follows: (1) in favor of the election of each of the Board’s nominees for director (including the TRT Nominees), and (2) in accordance with the Board’s recommendation with respect to any (i) proposal requesting ratification of the Issuer’s independent registered public accounting firm, (ii) proposal to approve, on an advisory basis, the compensation of the Issuer’s named executive officers, and (iii) non-binding shareholder proposal under Section 14a-8 of the Securities Exchange Act of 1934.

The Letter Agreement also provides that until the 2017 Annual Meeting the Issuer and the Reporting Persons will not disparage each other, subject to certain exceptions set forth in the Letter Agreement.

The description of the Letter Agreement set forth above does not purport to be complete and is qualified in its entirety by reference to the Letter Agreement, a copy of which is attached hereto as Exhibit 99.1 and incorporated herein by reference.
