RE: Crown LNG Holdings Limited (the Company)—Registration under the US Securities Act of 1933, as amended (the Securities Act)

1 Background

1.1 In connection with the draft Registration Statement on Form F-4 (Registration No. 333-) (as amended, the Registration Statement) filed by the Company today with the Securities and Exchange Commission pursuant to the Securities Act), you have asked us to furnish our opinion with regard to the laws of Jersey as to the legality of the securities being registered under the Registration Statement.

1.2 The Registration Statement relates to the registration by the Company under the Securities Act of:

(a) up to an aggregate of 85,428,192 ordinary shares of no par value in the capital of the Company (including 15,333,333 ordinary shares of no par value issuable upon exercise of the Warrants (as defined below)) (the Shares); and

(b) 15,333,333 warrants to purchase Shares (the Warrants),

issuable pursuant to the terms of the Business Combination Agreement (as defined below) and other transaction documents contemplated thereby.

1.3 In this opinion, “non-assessable” means, in relation to a Share, that the consideration for which the Company agreed to issue that Share has been or will be paid in full to the Company, so that no further sum is payable to the Company by any holder of that Share in respect of the purchase price of that Share.
