On February 27, 2020, Seaspan consummated a holding company reorganization (the “Reorganization”) pursuant to which Seaspan became a wholly-owned subsidiary of Atlas and Atlas is the successor issuer to Seaspan.  On completion of the Reorganization, the outstanding common shares and preferred shares of Seaspan were cancelled and the holders of such cancelled shares received common shares and preferred shares of Atlas, on a one-for-one basis with the same number of shares and same ownership percentage of the same corresponding class of Seaspan shares as they held immediately prior to the Reorganization.

In connection with the Reorganization, Seaspan removed the Notes from listing on the New York Stock Exchange (the “NYSE”) and from registration under the Exchange Act.  Descriptions of the deregistered Notes are contained in the following prospectuses filed with the Securities and Exchange Commission (the “SEC”):

• in the case of the 2025 Notes, the prospectus dated June 22, 2018 on Form 424B3 with Registration Number 333-225681 (filed with the SEC on June 22, 2018);

As at the date hereof, Atlas has the following securities registered under Section 12 of the Exchange Act:

(5) 7.875% Cumulative Redeemable Perpetual Preferred Shares – Series H; and

(6) Fixed-To-Floating Cumulative Redeemable Perpetual Preferred Shares – Series I.

A summary of the material terms of the common shares and preferred shares of Atlas has been previously filed as Exhibit 99.1 to Atlas’ Form 6-K (File No. 001-39237) furnished to the SEC on February 27, 2020.  The summary is qualified by reference to the Republic of the Marshall Islands Business Corporations Act (the “BCA”) and Atlas’ Amended and Restated Articles of Incorporation, Atlas’ Amended and Restated Bylaws and the Statement of Designation for each series of Atlas preferred shares, each of which is incorporated by reference as an exhibit to the Annual Report on Form 20-F of which this Exhibit is a part.  In addition, certain Marshall Islands company considerations are set forth below.

MARSHALL ISLANDS COMPANY CONSIDERATIONS

Atlas’ corporate affairs are governed by Atlas’ articles of incorporation and bylaws and by the BCA. The provisions of the BCA resemble provisions of the corporation laws of a number of states in the United States. While the BCA also provides that it is to be interpreted according to the laws of the State of Delaware and other states with substantially similar legislative provisions, there have been few, if any, court cases interpreting the BCA in the Marshall Islands and we cannot predict whether Marshall Islands courts would reach the same conclusions as U.S. courts. Accordingly, you may have more difficulty in protecting your interests in the face of actions by our management, directors or controlling shareholders than would shareholders of a corporation incorporated in a U.S. jurisdiction that has developed a substantial body of case law. The following table provides a comparison between the statutory provisions of the BCA and the Delaware General Corporation Law relating to certain shareholders’ rights.
