We are lawyers licensed and qualified to practice law in the British Virgin Islands. We have acted as special British Virgin Islands counsel to the Company to provide this legal opinion in connection with the Company's Registration Statement on Form S-1 (File number 333-287114), including all amendments or supplements thereto (“Form S-1”), filed with the Securities and Exchange Commission (the “Commission”) under the United States Securities Act of 1933 (the “Act”), as amended, (the “Registration Statement”) related to the underwritten public offering of (i) 10,000,000 units (the “Units”) in the Company with each Unit consisting of one Class A ordinary share in the Company of no par value (the “Public Shares”), and one-seventh of one right to receive one Ordinary Share (the “Rights”) (ii) up to 1,500,000 Units (the “Over-Allotment Units”) for which the underwriters have been granted an over-allotment option; and a private placement of (i) 330,000 private placement units (“Private Units”) (ii) up to 30,000 private units if the over-allotment option is exercised in full (“Private Over-Allotment Units”) consisting of one Class A ordinary share (“Private Shares”) and one-seventh (1/7) of one right (“Private Right”) and (v) all Public Shares and Private Shares (“Ordinary Shares”) issuable upon conversion of the Rights and the Private Rights included in the Units and the Private Units, and the Over-Allotment Units and the Private Over-Allotment Units.

2	Assumptions

In giving this opinion we have assumed, without further verification, the completeness and accuracy of the Registered Agent’s Certificate and that the information contained in such certificate remains accurate as at the date of this opinion. We have also relied upon the following assumptions, which we have not independently verified:

2.5	There is nothing under any law (other than the law of the British Virgin Islands) which would or might affect the opinions hereinafter appearing. Specifically, we have made no independent investigation of the laws of the State of New York.

5.2	To the filing of this opinion as an exhibit to the Registration Statement.

This opinion is limited to the matters detailed herein and is not to be read as an opinion with respect to any other matter.

Yours faithfully
