Opinion

Based upon the foregoing and subject to the qualifications set out below and having regard to such legal considerations as we deem relevant, we are of the opinion that the Common Shares to be issued by the Company have been duly and validly authorised, and when issued, sold and paid for in accordance with the Plan, the Resolutions and the Minutes and when appropriate entries have been made in the register of members of the Company in respect thereof will be legally and validly issued and will be fully paid and non-assessable.

Qualifications

This opinion is subject to the following qualification and limitation that under the Companies Law (2007 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 (2007 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).
