COMPANY PROPOSAL

TO APPROVE THE INCREASE IN THE COMPANY’S AUTHORISED SHARE CAPITAL

The authorised share capital of the Company is US$6,875,000 consisting of 137,500,000 common shares, par value US$0.05 each of which 112,278,065 common shares are in issue. The Company has approximately 12,528,610 million authorised common shares reserved for issuance in connection with its Convertible Bond and the balance of its authorised and unissued shares reserved for issuance in connection with share options granted pursuant to the Company’s Stock Option Plan. The Company therefore does not have any authorised but unissued share capital available. On May 21, 2020, the Company placed 46,153,846 new depositary shares, representing the beneficial interests in the same number of the Company’s underlying common shares, equal to $2,307,692.30 share capital divided into 46,153,846 common shares of US$0.05 par value each. Settlement of this offering is pending and requires us to obtain an authorisation to increase the share capital of the Company in order to settle this offering. The shares were offered to raise funds for general corporate purposes and will be used to strengthen the Company’s working capital. At the Meeting the Board will ask the Shareholders to approve the increase of the Company’s authorised share capital from US$6,875,000 divided into 137,500,000 common shares of US$0.05 par value each to US$9,182,692.30 divided into 183,653,846 common shares of US$0.05 par value each by the authorisation of an additional 46,153,846 common shares of US$0.05 par value each. The increase will result in authorised share capital of US$9,182,692.30 comprising 183,653,846 common shares of US$0.05 per value each.

The equity raise referenced above has not been and will not be registered under the US Securities Act of 1933 and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements of the US Securities Act of 1933.
