Separately, as part of the Annual Meeting process, the Company announced today
that John Kittmer, one of the Company's existing directors, has informed the
Company that he does not wish to run for re-election in order to pursue other
activities. All of the other current directors of the Company were nominated for
re-election. Mr. Kittmer has acted as a director of the Company for six years,
and the Company is grateful for his service. 

The Company has decided to nominate Mr. Francis "Frank" Dunne for election as a
director, to potentially fill the vacancy that would have been created by Mr.
Kittmer not running for re-election. Mr. Dunne has more than 40 years of legal
experience in maritime law and transactions involving major international
shipping finance lenders, shipowners, joint ventures, charter structures, new
building contracts, and ship and corporate acquisitions. Mr. Dunne was a partner
of Watson Farley & Williams LLP for 35 years and served as its Chairman for 13
years. He established Watson Farley & Williams LLP's presence in Greece. He has
won numerous awards and accolades in his career.

The Company's executive management team will remain unchanged. They will
continue to work closely with the Company's board of directors.

Mr. Ioannis Alafouzos, Chairman of the Company, commented:

"On behalf of the Company's board of directors and the Company, I express our
sincere appreciation to John for his service. During the last six years, since
our IPO in Norway, his commitment and support to the Company has been
instrumental, and our cooperation exemplary. We wish him the best in all his
future endeavors. We are pleased, however, that we are able to nominate Frank to
fill the vacancy. We believe that Frank's extensive legal experience in a broad
range of  maritime transactions and his prominent stature within the shipping
industry will add significant value and depth to our board. We are proud of the
experience, diverse expertise and skill possessed by our directors and we look
forward to welcoming Frank and continuing our track record of trust and success
that we have been building since 2018."
