SCHEDULE 13D

The following constitutes Amendment No. 1 to the Schedule 13D filed by the undersigned (“Amendment No. 1”). This Amendment No. 1 amends, supplements and, to the extent inconsistent with, supersedes the Schedule 13D filed with the Securities and Exchange Commission (the “SEC”) on November 17, 2021.

Item 4. PURPOSE OF TRANSACTION

Item 4 is hereby amended and restated as follows:

The Reporting Persons acquired the shares of Common Stock to which this Schedule 13D relates in the ordinary course of business for investment purposes because they believe that the shares are undervalued and represent an attractive investment opportunity.

On November 16, 2021, Ocean Capital sent a letter by email to the Issuer (the “Notice”), providing notice of intent to (i) nominate Brent D. Rosenthal and José R. Izquierdo II (together, the “Nominees”) for election to the Board at the Issuer’s upcoming 2021 annual meeting of shareholders (the “Annual Meeting”) and (ii) propose to repeal any provision of, or amendment to, the Issuer’s bylaws adopted by the Board without shareholder approval subsequent to November 16, 2021, the date of the Notice. A copy of the Notice was delivered to the Issuer on November 17, 2021. In connection with the submission of the Notice, the Reporting Persons filed a preliminary proxy statement with the SEC on November 17, 2021.

On December 7, 2021, the Reporting Persons filed their definitive proxy statement and accompanying BLUE proxy card with the SEC in connection with their solicitation of proxies for the Annual Meeting. The Reporting Persons will seek shareholder support for Ocean Capital’s proposals to (i) elect the Nominees to the Board and (ii) repeal any provision of, or amendment to, the Issuer’s bylaws adopted by the Board without shareholder approval subsequent to November 16, 2021. The Reporting Persons are asking shareholders to vote on their BLUE proxy card “FOR ALL” of the Nominees and “FOR” the repeal of any provision of, or amendment to, the Issuer’s bylaws adopted by the Board without shareholder approval subsequent to November 16, 2021.

The Nominees’ biographies are set forth below. Additional information regarding Ocean Capital’s proposals can be found in the Reporting Persons’ definitive proxy statement filed with the SEC on December 7, 2021.

José R. Izquierdo II, age 38, is a San Juan-based attorney with over a decade of experience in both the private and public sectors. Currently, he is the Member and Managing Director of Main Line Ventures, LLC, a firm that counsels corporations, international organizations and world-class athletes on a range of legal, strategic and developmental matters. Mr. Izquierdo previously served as General Secretary of the World Boxing Organization’s Executive Committee, an international non-profit organization. At the government level, Mr. Izquierdo has served as Executive Director of the Puerto Rico Tourism Company, a public corporation responsible for stimulating, promoting and regulating the development of Puerto Rico’s tourism industry, from 2017 to 2018, member of the Governor of Puerto Rico’s fiscal transition team, member of the Government of Puerto Rico’s Economic Development Council, Assistant Secretary of Economic Development and has sat on numerous boards of directors. Mr. Izquierdo served as Principal at The Law Offices of José R. Izquierdo II. Mr. Izquierdo is a 2005 graduate of Haverford College and holds a Juris Doctorate from the University of Puerto Rico School of Law. Ocean Capital believes Mr. Izquierdo’s extensive leadership experience at both the public and private sectors makes him qualified to serve as a director of the Issuer.
