As a result, Mr. Englander may be deemed to have shared voting control and investment discretion over securities deemed to be beneficially owned by Millennium Management.

Note: Integrated Holding Group, L.P., a Delaware limited partnership ("Integrated Holding Group"), is a non-managing member of Millenco. As a non-managing member, Integrated Holding Group has no investment or voting control over Millenco or its securities positions.

(b) Percent of Class:

Millennium Management and Mr. Englander may be deemed to be the beneficial owners of 2.1% of the Company’s Ordinary Shares (see Item 4(a) above). The calculation of the foregoing percentage is on the basis of 14,191,294 Ordinary Shares outstanding as of March 31, 2007, as reported by the Company on its Form 6-K, dated June 7, 2007.
