Based upon the examinations and assumptions stated herein and upon such searches as we have conducted 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 the Cayman Islands, we give the following opinions in relation to the matters set out below.

1. The Company is an exempted company duly incorporated with limited liability, validly existing under the laws of the Cayman Islands and is in good standing with the Registrar of Companies in the Cayman Islands.

2. The authorised share capital of the Company is currently US$50,000 divided into 500,000,000 Ordinary Shares and there will be no change to the authorised share capital upon the commencement of the trading of the Ordinary Shares on the Nasdaq stock exchange.

3. Subject to and upon the execution by Board of Directors of the Company of the Draft Resolutions, the Ordinary Shares, as contemplated by the Registration Statement, will be duly authorised by all necessary corporate action of the Company, and upon the issue of the Ordinary Shares (by the entry of the name of the registered owner thereof in the Register of Members of the Company confirming that such Ordinary Shares have been issued and credited as fully paid), delivery and payment therefor by the purchaser in accordance with the Amended Memorandum and Articles of Association (as defined in Schedule 1) and in the manner contemplated by the Registration Statement, the Ordinary Shares will be validly issued, fully paid and non-assessable (meaning that no additional sums may be levied in respect of such Ordinary Shares on the holder thereof by the Company).

4. Subject to and upon the execution by Board of Directors of the Company of the Draft Resolutions, the Warrant Shares, to be issued upon exercise of the Public Warrants as contemplated by the Warrant Documents (as defined in Schedule 1), will be duly authorised by all necessary corporate action of the Company and upon the issue of such Warrant Shares (by the entry of the name of the registered owner thereof in the Register of Members of the Company confirming that such Warrant Shares have been issued and credited as fully paid), delivery and exercise of the Public Warrants in accordance with and in the manner contemplated by the Registration Statement and the Warrant Documents, such Warrant Shares will be validly issued, fully paid and non-assessable (meaning that no additional sums may be levied in respect of such Warrant Shares on the holder thereof by the Company).

5. The execution, delivery and performance of the Warrant Documents to which the Company is a party have been authorised by and on behalf of the Company and, once such Warrant Documents have been executed and unconditionally delivered by the Company, such documents, will be duly executed and delivered on behalf of the Company and will constitute the legal, valid and binding obligations of the Company enforceable in accordance with their terms.

We hereby consent to the use of this opinion in, and the filing hereof as an exhibit to, the Registration Statement and to the reference to our firm under the heading “Legal Matters” and elsewhere in the prospectus included in the Registration Statement. In giving such consent, we do not thereby admit that we come within the category of persons whose consent is required under Section 7 of the U.S. Securities Act of 1933, as amended, or the Rules and Regulations of the Commission thereunder.

SCHEDULE 3

QUALIFICATIONS

1. The term “enforceable” and its cognates as used in this opinion means that the obligations assumed by any party under the Documents are of a type which the courts of the Cayman Islands (the “Courts” and each a “Court”) enforce. This does not mean that those obligations will necessarily be enforced in all circumstances in accordance with their terms. In particular:

(a) enforcement of obligations and the priority of obligations may be limited by bankruptcy, insolvency, liquidation, restructuring, reorganisation, readjustment of debts or moratorium and other laws of general application relating to or affecting the rights of creditors or by prescription or lapse of time;

(b) enforcement may be limited by general principles of equity and, in particular, the availability of certain equitable remedies such as injunction or specific performance of an obligation may be limited where a Court considers damages to be an adequate remedy;

(c) claims may become barred under statutes of limitation or may be or become subject to defences of set-off, counterclaim, estoppel and similar defences;

(d) where obligations are to be performed in a jurisdiction outside the Cayman Islands, they may not be enforceable in the Cayman Islands to the extent that performance would be illegal under the laws of, or contrary to the public policy of, that jurisdiction;

(e) a judgment of a Court may be required to be made in Cayman Islands dollars;

(f) to the extent that any provision of the Documents is adjudicated to be penal in nature, it will not be enforceable in the Courts; in particular, the enforceability of any provision of the Documents that is adjudicated to constitute a secondary obligation which imposes a detriment on the contract-breaker out of all proportion to any legitimate interest of the innocent party in the enforcement of the primary obligation may be limited;

(g) to the extent that the performance of any obligation arising under the Documents would be fraudulent or contrary to public policy, it will not be enforceable in the Courts;

(h) in the case of an insolvent liquidation of the Company, its liabilities are required to be translated into the functional currency of the Company (being the currency of the primary economic environment in which it operated as at the commencement of the liquidation) at the exchange rates prevailing on the date of commencement of the voluntary liquidation or the day on which the winding up order is made (as the case may be);

WALKERS Page 9

(i) a Court will not necessarily award costs in litigation in accordance with contractual provisions in this regard; and

(j) the effectiveness of terms in the Documents excusing any party from a liability or duty otherwise owed or indemnifying that party from the consequences of incurring such liability or breaching such duty shall be construed in accordance with, and shall be limited by, applicable law, including generally applicable rules and principles of common law and equity.

2. Our opinion as to good standing is based solely upon receipt of the Certificate of Good Standing issued by the Registrar. The Company shall be deemed to be in good standing under section 200A of the Companies Act (as amended) of the Cayman Islands (the “Companies Act”) on the date of issue of the certificate if all fees and penalties under the Companies Act have been paid and the Registrar has no knowledge that the Company is in default under the Companies Act.

3. We express no opinion upon any provisions in the Memorandum and Articles of Association, the Amended Memorandum and Articles of Association or any document which contains a reference to any law or statute that is not a Cayman Islands law or statute.
