Dear Company

AIR GLOBAL PLC (THE "COMPANY")

We act as Jersey legal counsel to the Company with respect to the business combination (the "Transaction") involving the Company pursuant to a business combination agreement dated 7 November 2025 (the "Business Combination Agreement").

We have been asked to provide this legal opinion to you with regard to the laws of Jersey in relation to the Registration Statement on Form F-1 (the "F1 Registration Statement") being filed with the Securities and Exchange Commission in relation to the Company's registration under the US Securities Act of 1933, as amended (the "Securities Act") of up to 154,623,867 ordinary shares with a par value of US$0.0001 per share (the "Shares") in connection with the Business Combination Agreement.

For the purposes of giving this opinion, we have examined and relied upon the originals, copies or translations of the documents listed in Schedule 1 (the "Documents").

In giving this opinion we have relied upon the assumptions set out in Schedule 2, which we have not independently verified.

We are Jersey lawyers and express no opinion as to any laws other than the laws of Jersey in force and as interpreted at the date of this opinion. We have not, for the purposes of this opinion, made any investigation of the laws, rules or regulations of any other jurisdiction. Except as explicitly stated herein, we express no opinion in relation to any representation or warranty contained in the Documents nor upon matters of fact or the commercial terms of the transactions contemplated by the Documents.

Based upon the foregoing examinations and assumptions and having regard to legal considerations which we consider relevant, and subject to the qualifications set out in Schedule 3, and under the laws of Jersey, we give the following opinions in relation to the matters set out below.

In this opinion, the term "non-assessable" means, in respect of a Share, that the consideration for which the Company has agreed to issue that Share has been received in full to the Company, such that no further or additional sum is payable to the Company or owed by the holder of that Share in respect of the issue price of that Share.

OPINION

As a matter of Jersey law, and on the basis of and subject to the assumptions and qualifications set out herein, we are of the opinion that, the Shares have been validly issued, are fully paid and non-assessable.

SCHEDULE 3

QUALIFICATIONS

The obligations of the Company under, or in respect of, the Shares will be subject to any law from time to time in force relating to bankruptcy, insolvency, liquidation, reorganization or administration or any other law or legal procedure affecting generally the enforcement of creditors' rights.

Our opinion is subject to any matter of fact that has not been disclosed to us.

The register of members of a Jersey company is prima facie evidence of any matters which are by the CJL directed or authorized to be inserted in it. The CJL requires that the register of members of a Jersey company includes, among other things, the name and address of every member and, where he or she is a member because he or she holds shares in the company, the number of shares held by the member and, in the case of shares which are not fully paid, the amount remaining unpaid on each share.
