SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Exchange Act requires our executive officers and directors, and persons who beneficially own more than 10% of our common stock, to file initial reports of ownership and reports of changes in ownership with the SEC and the New York Stock Exchange (“NYSE”). Executive officers, directors and greater-than-10% beneficial owners are required by SEC rules to furnish us with copies of all Section 16(a) reports they file.

Based solely on our review of these reports and written representations from our executive officers and directors, we believe that all of our executive officers and directors complied with all Section 16(a) filing requirements during 2008, with the exception of Ms. Hooper who made a late filing related to a purchase of stock on the open market.
