Audit Committee Charter

The purpose of the Audit Committee is to provide assistance to the Board in fulfilling the Board’s responsibilities to the Corporation and its shareholders relating to the accounting and financial reporting process and the audit of the Corporation’s financial statements. To that end, the Audit Committee will oversee management’s processes and activities relating to:

• maintaining the reliability and integrity of the Corporation’s accounting policies, financial reporting practices and financial statements;
• the independent auditor’s qualifications and independence;
• the performance of the Corporation’s internal audit function and independent auditor; and
• confirming compliance with U.K. and U.S. Federal laws and regulations, and the requirements of any stock exchange or quotation system on which the Corporation’s securities may be listed.

The Audit Committee will prepare the report required by the rules of the Securities and Exchange Commission (the “Commission”) to be included in the Corporation’s annual proxy statement.

The Audit Committee will consist of no fewer than three members. The Audit Committee will be composed of directors who satisfy the independence, experience and financial expertise requirements set forth in the Corporate Governance Rules of The NASDAQ Stock Market, Inc., Section 10A of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), including the rules and regulations promulgated thereunder, and all other applicable legal and regulatory requirements. In addition, at least one member of the Audit Committee will have past employment experience in finance or accounting, requisite professional certification in accounting, or other comparable experience or background which results in the individual’s financial sophistication, including a current or past position as a chief executive or financial officer or other senior officer with financial oversight responsibilities. The Board may, in its discretion, determine that one or more members of the Audit Committee are “financial experts” as defined by the Commission.

The members of the Audit Committee will be appointed, and may from time to time be removed, by the Board. The Board will take into account any recommendations of the Nominating and Corporate Governance Committee in making such appointments.

The Audit Committee will meet on a regular basis, but no less frequently than four times per year, and shall hold special meetings as required. Periodically the Audit Committee will meet with management, the internal auditors (or other personnel responsible for the internal audit) and the independent auditor in separate executive sessions in furtherance of its purposes.

Meetings of the Audit Committee may be called by or at the request of the Board, the Chairperson of the Audit Committee, any two members of the Audit Committee or the Chief Executive Officer. Notice of a meeting of the Audit Committee stating the place, day and hour of the meeting shall be given to each member of the Audit Committee at least one day prior thereto by mail, personal delivery or by telephone, telegraph, electronically transmitted facsimile or other form of wire or wireless communication. The method of notice need not be the same to each member of the Audit Committee.

In furtherance of the purposes set forth above, the Audit Committee will perform the functions and responsibilities described in this Charter as appropriate and will have all powers of the Board necessary or desirable to perform such functions and responsibilities as may be delegated to a committee of the Board under English law. Notwithstanding the enumeration of specific functions and responsibilities herein, the Audit Committee believes that its policies and procedures should remain flexible, in order to best respond to changing circumstances and conditions in fulfilling its responsibilities to the Corporation and its shareholders. The Audit Committee will by resolution establish its own rules and regulations for all meetings. In the absence of such rules and regulations, the provisions of the Corporation’s articles of association generally applicable to committees of the Board will apply.

The Audit Committee will have sole authority to appoint or replace the independent auditor (subject, if applicable, to shareholder approval). The Audit Committee will be directly responsible for the oversight of the work of the independent auditor (including resolution of disagreements between management and the independent auditor regarding financial reporting) for the purpose of preparing or issuing an audit report or related work or performing other audit, review or attest services. The independent auditor will report directly to the Audit Committee.

All auditing services and permitted non-audit services (including the fees and terms thereof) to be performed for the Corporation by its independent auditor must be approved by the Audit Committee in advance, subject to the de minimus exceptions for non-audit services described in Section 10A(i)(l)(B) of the Exchange Act which are approved by the Audit Committee prior to the completion of the audit. The Audit Committee may form and delegate authority to subcommittees consisting of one or more members or may delegate authority to one or more members, including the authority to grant preapprovals of audit and permitted non-audit services, provided that all decisions to grant preapprovals pursuant to such delegated authority will be presented to the entire Audit Committee at its next scheduled meeting.

The Audit Committee will have the authority, to the extent it deems necessary or appropriate to carry out its functions and responsibilities, to retain independent legal, accounting or other advisors. The Corporation will provide for appropriate funding, as determined by the Audit Committee, for the payment of compensation to the independent auditor for the purpose of rendering or issuing an audit report or related work or performing other audit, review or attest services and to any advisors employed by the Audit Committee.

The Audit Committee will make regular reports to the Board. The Audit Committee will review and reassess the adequacy of this Charter annually and recommend any proposed changes to the Board for approval. The Audit Committee will periodically review the Audit Committee’s own performance.

In addition, the Audit Committee will:
