 a general authority from our shareholders to enable our Company to purchase its shares in the markets. Further, the Company believes it is important to promote equality between shareholders, regardless of the exchange on which the shares they hold trade. The Board of Directors would only repurchase shares if it believes it is in the best interests of the Company and its shareholders, taking into account the Company’s overall financial position. The Board of Directors has no immediate plans to repurchase any shares pursuant to this mandate, and we are not asking shareholders to approve a specific repurchase of shares.

The Board of Directors recommends shareholder approval of a Repurchase Mandate of up to 10% of the total number of issued ordinary shares of the Company (excluding treasury shares) as of the date of the Annual Meeting. If approved by shareholders, the Repurchase Mandate will remain in force until the next annual general meeting, unless otherwise earlier revised or revoked by shareholders at a general meeting.

#### Vote Required
Approval of Proposal 14 requires the favorable vote of a simple majority of the votes cast by the shareholders entitled to vote who are present in person, virtually, or by proxy at the Annual Meeting. Broker non-votes and abstentions with respect to Proposal 14 will not be treated as votes cast for this purpose and, therefore, will not affect the outcome of the vote.

THE APPROVAL OF A MANDATE TO REPURCHASE UP TO 10% OF THE TOTAL NUMBER
OF ISSUED ORDINARY SHARES OF THE COMPANY (EXCLUDING TREASURY SHARES)
AS OF THE DATE OF THE ANNUAL MEETING.
