Item 4.

Purpose of the Transaction

Item 4 of the Amended Statement is hereby amended to add the following:

On May 3, 2021, the Reporting Persons entered into a Cooperation Agreement (“Cooperation Agreement”) with the Issuer. Pursuant to the Cooperation Agreement, the Issuer has agreed to increase the size of its Board of Directors (“Board”) from seven to eight directors, to nominate Mr. Robotti to its Board for election at the Issuer’s 2021 Annual Meeting of Stockholders (“2021 Annual Meeting”) and, upon his election, to appoint Mr. Robotti to serve on the Compensation Committee of the Board (subject only to Mr. Robotti’s satisfaction of the requirements of the New York Stock Exchange and applicable law which shall be determined by the Board and any applicable committee of the Board prior to the 2021 Annual Meeting). Pursuant to the Cooperation Agreement, the Reporting Persons have agreed to withdraw their nomination of persons for election as directors of the Issuer at the Issuer’s 2021 Annual Meeting and their demand for certain stockholder list information relating to the Issuer, to vote in favor of the Issuer’s nominees and proposals except as described below, and to abide by certain other customary standstill provisions.

The Reporting Person’s rights and the Issuer’s obligations under the Cooperation Agreement to nominate Mr. Robotti at the 2021 Annual Meeting and appoint Mr. Robotti to the Compensation Committee are conditioned on the Reporting Persons’ Net Long Position (as defined in the Cooperation Agreement) not falling at any time below 1,425,025 shares of the Issuer’s common stock, $0.001 par value per share (the “Common Stock”), representing 3.5% of the outstanding shares of Common Stock as of the effective date of the Cooperation Agreement (the “Minimum Ownership Threshold”), subject to certain exceptions set forth in the Cooperation Agreement. In addition, if at any time the Reporting Persons’ Net Long Position falls below the Minimum Ownership Threshold, Mr. Robotti shall immediately tender his resignation letter as a director to the Board which letter has been delivered in advance. During the term of the Cooperation Agreement, the size of the board shall not exceed nine (9) directors without the unanimous written consent of all of the directors on the Board, other than in connection with any merger or acquisition approved by a majority of the directors then serving on the Board.

With respect to each annual or special meeting of the Issuer’s stockholders during the term of the Cooperation Agreement, the Reporting Persons agreed to vote the shares of Common Stock it holds in accordance with the Board’s recommendations on proposals regarding the election or removal of directors (each such proposal, a “Director Proposal”) and any other proposal to be submitted to the stockholders by either the Issuer or any stockholder of the Issuer. The Reporting Persons may, however, vote in accordance with the recommendation of Institutional Shareholder Services Inc. or Glass Lewis & Co., LLC if it differs from the Board’s recommendation with respect to any proposal submitted by the Issuer or any of its stockholders (other than a Director Proposal) and the Reporting Persons may vote in their discretion on certain extraordinary transactions.

The Reporting Persons have also agreed to certain customary standstill provisions prohibiting them from, among other things, (i) making certain announcements regarding or proposing certain extraordinary transactions relating to the Issuer, (ii) soliciting proxies, (iii) selling securities of the Issuer outside of the public markets which results in any third party owning more than 4.9% of the outstanding shares of the Common Stock (subject to certain exceptions set forth in the Cooperation Agreement), (iv) taking actions to change or influence the Board, Issuer management or the direction of certain Issuer matters other than Mr. Robotti in his capacity as a director, and (v) exercising certain stockholder rights.

The Issuer agreed to reimburse the Reporting Persons for their reasonable, documented out-of-pocket fees and expenses incurred in connection with the 2021 Annual Meeting and the negotiation and execution of the Cooperation Agreement, in an amount not to exceed $200,000 in the aggregate.

SCHEDULE 13D
CUSIP No. 88642R109			Page 16 of 22 Pages

The Cooperation Agreement will terminate on the date that is the earlier of (i) one hundred fifty (150) days prior to the 2022 annual meeting of stockholders of the Issuer (the “2022 Annual Meeting”) and (ii) one hundred fifty (150) days prior to the first anniversary of the 2021 Annual Meeting, except that if the Issuer notifies the Reporting Persons that the Board has determined to nominate Mr. Robotti for election at the 2022 Annual Meeting by no later than the earlier of (i) one hundred sixty-five (165) days prior to the 2022 Annual Meeting and (ii) one hundred sixty-five (165) days prior to the first anniversary of the 2021 Annual Meeting, the term of the Cooperation Agreement will be extended until the date that is the earlier of (i) one hundred fifty (150) days prior to the 2023 annual meeting of stockholders of the Issuer and (ii) one hundred fifty (150) days prior to the first anniversary of the 2022 Annual Meeting.
