Schedule 3
QUALIFICATIONS
| 1. | This Opinion is subject to the following qualifications: |
| 1.1 | In this opinion 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, and in absence of a contractual arrangement, or an obligation pursuant to the Articles, to the contrary, 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 circumstances in which a court may be prepared to pierce or lift the corporate veil). |
| 1.2 | The register of members of a Cayman Islands company provides prima facie evidence of the legal ownership of registered shares in a company. No purported creation or transfer of legal title to Ordinary Shares is effective until the register of members is updated accordingly. However, an entry in the register of members may be subject to rectification (for example, in the case of fraud or manifest error). |
| 1.3 | Any issue of Ordinary Shares that takes place after the commencement of the winding up of the Company is void unless consented to by the liquidator (in the case of a voluntary winding up of the Company) or the courts of the Cayman Islands (in the case of a court-supervised winding up of the Company). |
| 1.4 | 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 within the time frame prescribed by law. |
