We have acted as special Bermuda legal counsel to the Company in connection with a registration statement on form S-3 filed with the U.S. Securities and Exchange Commission (the "Commission") on January 4, 2021 (the "Registration Statement", which term does not include any other document or agreement whether or not specifically referred to therein or attached as an exhibit or schedule thereto) relating to the shelf registration under the U.S. Securities Act of 1933, as amended (the "Securities Act"), of debt securities, ("Debt Securities"), Class A common shares, par value US$0.001 each ("Class A Common Shares"), preference shares, par value US$0.001 each ("Preference Shares"), depositary shares representing Class A Common Shares or Preference Shares or Debt Securities (“Depositary Shares”), warrants to purchase Class A Common Shares, Preference Shares or Debt Securities ("Warrants") and units consisting of any combination of the foregoing securities ("Units") of the Company (collectively, the Class A Common Shares, Preference Shares, Depositary Shares, Debt Securities, Warrants, and Units are referred to herein as the "Securities"). Class A Common Shares and Preference Shares are sometimes collectively referred to as “Equity Securities” which term includes Class A Common Shares and Preference Shares to be issued pursuant to the conversion, exchange or exercise of any other Securities and any Class A Common Shares or Preference Shares comprising any other Securities in whole or in part.

For the purposes of giving this opinion, we have examined a copy of the Registration Statement. We have also reviewed the memorandum of association and the bye-laws of the Company (together, the “Constitutional Documents”), each certified by the Assistant Secretary of the Company on December 31, 2020, minutes of a meetings of its directors held on December 8, 2020 (the "Resolutions") certified by the Assistant Secretary of the Company on December 31, 2020 and such other documents and made such enquiries as to questions of law as we have deemed necessary in order to render the opinion set forth below.

passed at one or more duly convened, constituted and quorate meetings, or by unanimous written resolutions, remain in full force and effect and have not been, and will not be, rescinded or amended, (e) that the Company will issue the Securities in furtherance of its objects as set out in its memorandum of association, (f) that the Constitutional Documents will not be amended in any manner that would affect the opinions expressed herein, (g) that there is no provision of the law of any jurisdiction, other than Bermuda, which would have any implication in relation to the opinions expressed herein, (h) that the Company will have sufficient authorised capital to effect the issue of any of the Equity Securities or other Securities convertible, exchangeable, exercisable or consisting of any Equity Securities at the time of issuance, whether as a principal issue or on the conversion, exchange or exercise of any Securities, (i) that the Company's shares will be listed on the New York Stock Exchange or another appointed stock exchange, as defined in the Companies Act 1981, as amended (the "Companies Act"), and the consent to the issue and free transfer of the Securities given by the Bermuda Monetary Authority as of June 1, 2005 will not have been revoked or amended at the time of issuance of any Securities, (j) that the form and terms of any and all Securities (including, without limitation, the designation, powers, preferences, rights, qualifications, limitations and restrictions of Preference Shares), the issuance and sale thereof by the Company, and the Company’s incurrence and performance of its obligations thereunder or in respect thereof (including, without limitation, its obligations under any related agreement, indenture or supplement thereto) in accordance with the terms thereof will not violate the Constitutional Documents nor any applicable law, regulation, order or decree in Bermuda, (k) that all necessary corporate action will be taken to authorise and approve any issuance of Securities (including, if Preference Shares are to be issued, all necessary corporate action to establish one or more series of Preference Shares and fix the designation, powers, preferences, rights, qualifications, limitations and restrictions thereof), the terms of the offering thereof and related matters, and that the applicable definitive purchase, underwriting or similar agreement and, if Debt Securities are to be issued, the applicable indenture and any applicable supplements thereto, will be duly approved, executed and delivered by or on behalf of the Company and all other parties thereto, (l) that the applicable purchase, underwriting or similar agreement, any Debt Security, any indenture and any supplement thereto and any other agreement or other document relating to any Security will be valid and binding in accordance with its terms pursuant to its governing law; (m) that the issuance and sale of and payment for the Securities will be in accordance with the applicable purchase, underwriting or similar agreement duly approved by the Board of Directors, the Registration Statement (including the prospectus set forth therein and any applicable supplement thereto) and, if Debt Securities are to be issued, the applicable indenture and any applicable supplements thereto, (n) that, upon the issue of any Equity Securities, the Company will receive consideration for the full issue price thereof which shall be equal to at least the par value thereof, (o) that the Company will comply, to the extent applicable, with the requirements of Part III of the Companies Act entitled "Prospectuses and Public Offers", and (p) the capacity, power and authority of all parties other than the Company to enter into and perform their obligations under any and all documents entered into by such parties in connection with the issuance of the Securities, and the due execution and delivery thereof by each party thereto.

1.The Company is duly incorporated and existing under the laws of Bermuda in good standing (meaning solely that it has not failed to make any filing with any Bermuda governmental authority or to pay any Bermuda government fee or tax which would make it liable to be struck off the Register of Companies and thereby cease to exist under the laws of Bermuda).

2.Upon the due issuance of Class A Common Shares and/or Preference Shares, Depositary Shares or any Warrants or Units consisting, in whole or in part, of any Common Shares and/or Preference Shares, and payment of the consideration therefor, such Common Shares and/or Preference Shares, including those underlying any Depositary Shares or forming a part of any Unit, will be validly issued, fully paid and non-assessable (which term means when used herein that no further sums are required to be paid by the holders thereof in connection with the issue of such shares).
