REGISTERED PUBLIC ACCOUNTING FIRM
The Audit Committee has appointed PricewaterhouseCoopers LLP (PwC) as our independent registered public accounting firm to audit the Companys consolidated financial statements for the fiscal year ending December 31, 2009. PwC, or its predecessor firms, has served as our independent accountants since our initial public offering in 1993. We are asking shareholders to ratify the appointment of PwC as our independent registered public accounting firm at the annual meeting. Representatives of PwC are expected to attend the meeting. They will have an opportunity to make a statement if they desire to do so, and will be available to respond to shareholders questions.
The ratification of PwC is not required by our bylaws or other organizational documents, but we are submitting the selection to our shareholders for ratification as a matter of good corporate governance.

The Audit Committee is required to pre-approve all audit and non-audit services provided by the Companys independent public accountants. In addition to separately approved services, the Audit Committees pre-approval policy provides for pre-approval of specifically described audit and non-audit services and related fee levels on an annual basis. The policy authorizes the Committee to delegate to one or more of its members pre-approval authority with respect to permitted services. The Audit Committee reviews the services performed pursuant to its pre-approval policy at its next scheduled quarterly meeting.
