ITEM 4.   PURPOSE OF TRANSACTION.
Coincident with the closing under the Securities Purchase Agreement, dated as of October 12, 2009 (the “2009 SPA”), among the Company and the purchasers named therein, all of the Company’s Preference Shares, including those held by the Reporting Persons, were converted into Ordinary Shares on a one-for-one basis. As a result, the rights attributable to the Preference Shares, including the right to elect four members of the board of directors of the Company, were terminated. The investors party to the Securities Purchase Agreement with the Company, dated May 13, 2008 (the “2008 SPA”), which include the Other Shareholders and the Reporting Persons, also agreed to (i) waive any preemptive rights they had with respect to the issuance of units under the 2009 SPA, (ii) the termination of the second tranche contemplated by the 2008 SPA and (iii) the termination of their right of first refusal to purchase up to their pro rata share of any offering by the Company of Ordinary Shares or any other class or series of capital stock, or any other security convertible into or exchangeable for Ordinary Shares or any other class or series of capital stock, and (iv) the termination of their registration rights under the 2008 SPA. As a result of the termination of foregoing rights, the Other Shareholders and the Reporting Persons no longer constitute a “group” within the meaning of Section 13(d)(3) of the Exchange Act.
