Item 3. | Source and Amount of Funds or Other Consideration |
Item 3 is hereby amended and restated to read as follows:The Shares purchased by HCPF 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 purchases.The aggregate purchase price of the 1,174,899 Shares beneficially owned by HCPF is approximately $2,612,823, including brokerage commissions.The 21,000 Shares beneficially owned directly by Mr. Manko were awarded to him in his former capacity as a director of the Issuer. | |
Item 4. | Purpose of Transaction |
Item 4 is hereby amended to add the following:Mr. Manko, who has been serving as a director of the Issuer since November 2023, submitted a letter of resignation (the "Resignation Letter") to the Issuer's Board of Directors (the "Board") resigning from the Board, effective April 16, 2025. In the Resignation Letter, Mr. Manko cited certain disagreements with the Issuer's governance practices and the composition and leadership of the Board, particularly with respect to Chairman Kenneth Potashner. More specifically, Mr. Potashner was nominated by the Board for re-election at the Issuer's 2025 Annual Meeting of Shareholders (the "2025 Annual Meeting"), a decision that Mr. Manko objected to in his capacity as a director, despite the Issuer's shareholders voting against the Chairman's re-election two years in a row. The Board's decision to renominate the Chairman for election at the 2025 Annual Meeting, in Mr. Manko's opinion, represents a failure of the Board to represent the best interest of all shareholders. For this reason, as well as others discussed in further detail in the Resignation Letter, Mr. Manko resigned from the Board, a decision that he did not take lightly.Given Mr. Manko's conviction in the value potential of the Issuer, he disclosed in the Resignation Letter that he intends to remain a shareholder of the Issuer and reserves all rights to take any action that he deems necessary to represent the best interests of all of shareholders. A copy of the Resignation Letter is attached hereto as Exhibit 99.1 and incorporated herein by reference. | |
