4 OPINIONS

Based upon, and subject to, the foregoing assumptions and qualifications, and having regard to such legal considerations as we deem relevant, we are of the opinion that:

4.1 The Company has been duly incorporated as an exempted company with limited liability and is validly existing and in good standing under the laws of the Cayman Islands.

The Registered Shares other than the Warrant Shares have been validly issued, fully paid and non-assessable. The Warrant Shares, once issued by the Company against payment in full of the consideration as set out in the Registration Statement and in accordance with the terms set out in the Registration Statement, such Warrant Shares will be validly issued, fully paid and non-assessable.

4.3 The execution, delivery and performance of the Warrant Document has been authorised by and on behalf of the Company and the Warrant Document has been duly executed and delivered on behalf of the Company and constitutes the legal, valid and binding obligations of the Company enforceable in accordance with its terms.

SCHEDULE 2

Assumptions

We have relied upon the following assumptions, which we have not independently verified:

1 The Documents have been or will be authorised and duly executed and unconditionally delivered by or on behalf of all relevant parties in accordance with all relevant laws (other than, with respect to the Company, the laws of the Cayman Islands);

2 the Documents are, or will be, legal, valid, binding and enforceable against all relevant parties in accordance with their terms under the laws of the State of New York and all other relevant laws (other than, with respect to the Company, the laws of the Cayman Islands);

3 the choice of the laws of the State of New York as the governing law of the Documents has been made in good faith and would be regarded as a valid and binding selection which will be upheld by the courts of the State of New York and any other relevant jurisdiction (other than the Cayman Islands) as a matter of the laws of the State of New York and all other relevant laws (other than the laws of the Cayman Islands);

4 copies of documents, conformed copies or drafts of documents provided to us are true and complete copies of, or in the final forms of, the originals;

5 all signatures, initials and seals are genuine;

6 the capacity, power, authority and legal right of all parties under all relevant laws and regulations (other than, with respect to the Company, the laws of the Cayman Islands) to enter into, execute, unconditionally deliver and perform their respective obligations under the Documents;

7 no invitation has been or will be made by or on behalf of the Company to the public in the Cayman Islands to subscribe for any of the Warrants or the Ordinary Shares;

8 no monies paid to or for the account of any party under the Documents represent or will represent criminal property or terrorist property (as defined in the Proceeds of Crime Act (Revised) and the Terrorism Act (Revised), respectively);

9 there is nothing under any law (other than the laws of the Cayman Islands) which would or might affect the opinions set out below. Specifically, we have made no independent investigation of the laws of the State of New York; and

10 the Company will receive money or money’s worth in consideration for the issue of the Ordinary Shares, and none of the Ordinary Shares were or will be issued for less than par value.

Save as aforesaid we have not been instructed to undertake and have not undertaken any further enquiry or due diligence in relation to the transaction the subject of this opinion.

SCHEDULE 3

Qualifications

The opinions expressed above are subject to the following qualifications:

1 The term “enforceable” as used in this opinion means that the obligations assumed by the Company under the Transaction Documents are of a type which the courts of the Cayman Islands will enforce. It does not mean that those obligations will necessarily be enforced in all circumstances in accordance with their terms. In particular:

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

(b) enforcement may be limited by general principles of equity. For example, equitable remedies such as specific performance may not be available, inter alia, where damages are considered to be an adequate remedy;

(c) some claims may become barred under the 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 that jurisdiction;

2 to maintain the Company in good standing under the laws of the Cayman Islands, annual filing fees must be paid and returns made to the Registrar of Companies within the time frame prescribed by law;

3 under Cayman Islands law, the register of members (shareholders) is prima facie evidence of title to shares and this register would not record a third party interest in such shares. However, there are certain limited circumstances where an application may be made to a Cayman Islands court for a determination on whether the register of members reflects the correct legal position. Further, the Cayman Islands court has the power to order that the register of members maintained by a company should be rectified where it considers that the register of members does not reflect the correct legal position. As far as we are aware, such applications are rarely made in the Cayman Islands and for the purposes of the opinion given in paragraph 3.2, there are no circumstances or matters of fact known to us on the date of this opinion letter which would properly form the basis for an application for an order for rectification of the register of members of the Company, but if such an application were made in respect of the Company’s Ordinary Shares, then the validity of such shares may be subject to re-examination by a Cayman Islands court;

4 except as specifically stated herein, we make no comment with respect to any representations and warranties which may be made by or with respect to the Company in any of the documents or instruments cited in this opinion letter or otherwise with respect to the commercial terms of the transactions the subject of this opinion letter; and

5 in this opinion letter, the phrase “non-assessable” means, with respect to the Ordinary Shares in the Company, that a shareholder shall not, solely by virtue of its status as a shareholder, be liable for additional assessments or calls on the Ordinary Shares by the Company or its creditors (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstance in which a court may be prepared to pierce or lift the corporate veil).
