Redemption and Exchange of Rights
At any time prior to the time that a person becomes an Acquiring Person, the Company may redeem the Rights in whole, but not in part, at a price of U.S. $0.001 per Right (the Redemption Price). The redemption of the Rights may be made effective at such time, on such basis and with such conditions as the Board in its sole discretion may establish. Immediately upon the action of the Board electing to redeem the Rights, the Company shall make announcement thereof, and upon such action, the right to exercise the Rights will terminate and the only right of the holders of Rights will be to receive the Redemption Price.
At any time after a person becomes an Acquiring Person and prior to the earlier of one of the events described in the last sentence of the previous paragraph or the acquisition by such Acquiring Person of 50% or more of the outstanding Ordinary Shares, the Board may exchange the Rights (other than Rights owned by an Acquiring Person, which will become void), in whole or in part, at an exchange ratio of one Ordinary Share, and of other securities, cash or other assets deemed to have the same value as one Ordinary Share, per Right, subject to adjustment.
Until the Rights are exercised or exchanged for Ordinary Shares, the holders thereof, as such, will have no rights as shareholders of the Company beyond those as an existing shareholder, including, without limitation, the right to vote or to receive dividends.
