Assumptions

The following opinions are given only as to, and based on, circumstances and matters of fact existing and known to us on the date of this opinion letter. These opinions only relate to the laws of the Cayman Islands which are in force on the date of this opinion letter. In giving the following opinions, we have relied (without further verification) upon the completeness and accuracy of the Director’s Certificate and the Certificate of Good Standing. We have also relied upon the following assumptions, which we have not independently verified:

2.1

Copies of documents or drafts of documents provided to us are true and complete copies of, or in the final forms of, the originals.

2.2

The genuineness of all signatures, initials and seals.

2.3

There is nothing under any law (other than the law of the Cayman Islands) which would or might affect the opinions set out below.

2.4

At the time of the exercise of the Warrant into Warrant Shares in accordance with the terms and provisions of the Securities Purchase Agreement (the “Exercise”):

(a)

the laws of the Cayman Islands (including the Companies Act (As Revised) (the “Companies Act”)) will not have changed in such way as to materially impact the Exercise;

(b)

the Company will have sufficient authorised but unallotted and unissued Ordinary Shares, in each case to effect the Exercise in accordance with the terms and provisions of the Warrant and the Companies Act;

(c)

the Company will be able to pay its debts as they fall due in the ordinary course of business immediately following the Exercise;

(d)

the Company will not have been struck off or placed in liquidation;

(e)

the issue price for Ordinary Shares to be issued on the Exercise will not be less than the par value of such Ordinary Shares; and

(f)

the terms and provisions of the Warrant relating to the Exercise will not have been altered, amended or restated.

Opinions

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

3.1

The issue and allotment of the Ordinary Shares have been duly authorised and when allotted, issued and paid for as contemplated in the Registration Statement, the Ordinary Shares will be legally issued and allotted, fully paid and non-assessable. As a matter of Cayman Islands law, a share is only issued when it has been entered in the register of members (shareholders).

3.2

When Warrant Shares are issued upon the Exercise as contemplated in the Registration Statement and entered as fully paid on the register of members (shareholders), such Warrant Shares will be duly issued as fully paid and non-assessable.

Qualifications

In this opinion the phrase “non-assessable” means, with respect to the shares in the Company, that a shareholder shall not, solely by virtue of its status as a shareholder and in absence of a contractual arrangement, to the contrary, be liable for additional assessments or calls on the 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 circumstances in which a court may be prepared to pierce or lift the corporate veil).

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 or otherwise with respect to the commercial terms of the transactions, which are the subject of this opinion.

We hereby consent to the filing of this opinion letter with the Commission as an exhibit to the Company’s Current Report on Form 8-K being filed on the date hereof and incorporated by reference into the Registration Statement and to the reference to our name under the headings “Enforceability of Civil Liabilities” and “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.

Yours faithfully
