Ladies and Gentlemen:
We have acted as special counsel to SEACOR Marine Holdings Inc., a Delaware corporation (the “Company” or “you”), in connection with the Registration Statement on FormS-8 (the “Registration Statement”) filed with the Securities and Exchange Commission pursuant to the Securities Act of 1933, as amended (the “SecuritiesAct”) on June 9, 2020. You have asked us to furnish our opinion as to the legality of the securities being registered under the Registration Statement. The Registration Statement relates to the registration of up to an aggregate of 2,114,821 shares (the “Shares”) of the Company’s common stock, par value $0.01 per share, issuable in respect of awards to be granted under the SEACOR Marine Holdings Inc. 2020 Equity Incentive Plan (the “Plan”).
In rendering the opinions expressed below, we have examined the General Corporations Law of the State of Delaware (the “DGCL”), the Registration Statement, the Plan and the form of award agreements relating to awards of Shares under the Plan and Company records, certificates, agreements and other documents, and such questions of law, as we have considered necessary or appropriate for the purposes of this opinion. In our examination, we have assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of all documents submitted to us as originals and the conformity with authentic original documents of all documents submitted to us as copies. As to various questions of fact material to this opinion, we have, when relevant facts were not independently established, relied upon certificates of officers and representatives of the Company and public officials and statements and representations contained in the Registration Statement, the Plan, and other documents as we have deemed necessary.
