The following constitutes Amendment No. 1 to the Schedule 13D filed by the undersigned (“Amendment No. 1”). This Amendment No. 1 amends the Schedule 13D as specifically set forth herein.

Item 3.

Source and Amount of Funds or Other Consideration.

Item 3 is hereby amended and restated to read as follows:

The Shares beneficially owned by the Reporting Persons were purchased with the working capital of certain private funds and managed accounts for which Alta Advisers serves as investment adviser (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 2,658,589 Shares beneficially owned by the Reporting Persons is approximately $7,605,230, excluding brokerage commissions.

Item 4.

Purpose of Transaction.

Item 4 is hereby amended to add the following:

On July 14, 2024, Alta Advisers entered into a Cooperation Agreement (the “Cooperation Agreement”) with the Issuer.

In accordance with the terms of the Cooperation Agreement, effective as of the date of the Cooperation Agreement, the Issuer increased the size of its board of directors (the “Board”) to nine (9) directors and appointed Stuart M. Duty and Andrew R. Saik (collectively, the “Initial New Directors”) to the Board to fill the resulting vacancies, each with a term expiring at the Issuer’s 2024 annual meeting of shareholders (the “2024 Annual Meeting”), or until their earlier death, disability, resignation, disqualification, or removal. Under the terms of the Cooperation Agreement, Mr. Duty was appointed to the Nominating and Corporate Governance Committee of the Board and Mr. Saik was appointed to the Audit Committee of the Board. Pursuant to the Cooperation Agreement, as soon as reasonably practicable after the date of the Cooperation Agreement (and in any event prior to September 6, 2024), the Issuer will increase the size of the Board and appoint an individual that is mutually agreeable to the Issuer and Alta Advisers as an independent director to the Board with a term expiring at the next annual meeting of shareholders, or until his or her earlier death, disability, resignation, disqualification, or removal. Pursuant to the Cooperation Agreement, Alta Fundamental Advisers Master L.P. irrevocably withdrew the notice it had provided to the Issuer under Rule 14a-19 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) of its intention to nominate five directors to stand for election at the 2024 Annual Meeting.

In accordance with the terms of the Cooperation Agreement, the Issuer has agreed to include the Initial New Directors on its slate of director nominees for both the 2024 Annual Meeting and the Issuer’s 2025 annual meeting of shareholders (the “2025 Annual Meeting”) and to solicit proxies for the election of, and support and recommend for the election of, the Initial New Directors at such meetings in the same manner as for the Issuer’s other director nominees.

Pursuant to the Cooperation Agreement, if either of the Initial New Directors resigns or otherwise ceases to be a director for any reason prior to the conclusion of the 2025 Annual Meeting (the “Termination Date”), and at such time Alta Advisers holds a Net Long Position (as defined in the Cooperation Agreement) at or above 4.0% of the Issuer’s then-outstanding Shares, the Issuer and Alta Advisers will cooperate in good faith to select, and the Board will appoint, as promptly as practicable, a director mutually agreeable to the Issuer and Alta Advisers, who must be independent under Nasdaq’s listing standards and may not be a principal, officer, manager, employee, affiliate or associate of Alta Advisers.

Prior to the Termination Date, Alta Advisers has agreed to vote all of its Shares in accordance with the Board’s recommendations on all proposals or business that may be the subject of shareholder action at shareholder meetings held prior to the Termination Date, except (i) if either Institutional Shareholder Services Inc. or Glass Lewis & Co., LLC recommends against the Board’s recommendation for a proposal (other than with respect to director elections), Alta Advisers may follow such alternative recommendation, and (ii) Alta Advisers may vote in its sole discretion with respect to any proposals with respect to an Extraordinary Transaction (as defined in the Cooperation Agreement) that is subject to a vote of the Issuer’s shareholders.

The Cooperation Agreement also contains customary standstill, non-disparagement and expense reimbursement provisions. The Cooperation Agreement remains in effect until the Termination Date unless the Cooperation Agreement is earlier terminated in accordance with its terms.

The foregoing summary of the Cooperation Agreement does not purport to be complete and is subject to, and qualified in its entirety, by the full text of the Cooperation Agreement, which is attached hereto as Exhibit 99.1 and incorporated herein by reference.
