PROPOSAL ONE

ELECTION OF DIRECTORS

The Company has nine directors on its Board. As provided in the Company’s Fourth Amended and Restated Articles of Incorporation and Third Amended and Restated Bylaws, the Board is divided into three classes and, after the initial term, each director is elected to serve for a three-year term and until such director’s successor is duly elected and qualified, except in the event of his death, resignation, removal or earlier termination of his term of office. Consistent with Article I(a) of the Fourth Amended and Restated Articles of Incorporation and Section 1 of Article III of the Third Amended and Restated Bylaws of the Company, whereby it is stated that the Board shall be divided into three classes of directors, as nearly equal in number as possible, Mr. Spyros Capralos was re-classed to serve as a Class B Director (formerly a Class C Director) on February 12, 2024, so that each class now currently consists of three directors. The term of our three Class B directors expires at the Meeting. The Board of Directors has determined to nominate Mr. Spyros Capralos, Mr. Koert Erhardt and Mr. Sherman Lau, current Class B directors, for re-election as Class B directors. The Class B term for the newly elected directors will expire at the Company’s 2027 Annual Meeting of Shareholders.

Unless the proxy is marked to indicate that such authorization is expressly withheld, the persons named in the enclosed proxy intend to vote the shares authorized thereby FOR the election of the following four nominees. It is expected that each of the nominees will be able to serve, but if before the election it develops that any of the nominees is unavailable, the persons named in the accompanying proxy will vote for the election of such substitute nominee or nominees as the current Board may recommend.
