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 Common Shares to be offered and sold by the Company as contemplated by the Form S-1 have been duly and validly authorised, and when issued and paid for in accordance with the terms of the underwriting agreement referred to in the Form S-1 and registered in the register of members (shareholders), such Common Shares will be legally issued, fully paid and non-assessable.

QUALIFICATIONS

This opinion is subject to the following qualification and limitation that under the Companies Law (2004 Revision) of the Cayman Islands, the register of members of a Cayman Islands company is by statute regarded as prima facie evidence of any matters which the Companies Law (2004 Revision) directs or authorises to be inserted therein. A third party interest in the shares in question would not appear. An entry in the register of members may yield to a court order for rectification (for example, in the event of fraud or manifest error).

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 the subject of this opinion.

In the giving our consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act or the Rules and Regulations of the Commission thereunder.

Yours faithfully
