You also may revoke your proxy by sending a notice of revocation to our Chief Financial Officer, which must be received by our Chief Financial Officer prior to the Meeting. Attending the Meeting will not cause your previously granted proxy to be revoked unless you specifically so request. However, if your shares are held in Street Name by your broker, bank or another nominee, you must contact your broker, bank or other nominee to confirm the procedures for changing your vote and/or revoking your proxy. What is the proxy card? The proxy card enables you to appoint each of Michael Klein, our Chief Executive Officer, President and Chairman, and Jay Taragin, our Chief Financial Officer, or failing them, the duly appointed chairman of the Meeting, as your representatives at the Meeting.

This way, your shares will be voted whether or not you attend the Meeting. Even if you plan to attend the Meeting, it is strongly recommended that you complete and return your proxy card before the Meeting date in case your plans change. What happens if I do not indicate how to vote my proxy? If you sign your proxy card without providing further instructions, your Ordinary Shares will be voted “FOR” the Auditor Ratification Proposal, in accordance with the recommendation of our Board as described below. If the Meeting is adjourned, Mr. Klein and Mr. Taragin, or failing them, the duly appointed chairman of the Meeting, can vote the shares on the new Meeting date as well, unless you have properly revoked your proxy instructions, as described elsewhere herein. What should I do if I receive more than one set of voting materials for the Meeting? You may receive more than one set of voting materials for the Meeting, including multiple copies of this Proxy Statement and multiple proxy cards or voting instruction cards. For example, if you hold your shares in more than one brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold shares. If you are a Shareholder of Record and your shares are registered in more than one name, you will receive more than one
