        <footnote id="F1">The reporting persons (&quot;Reporting Persons&quot;) are Westcliff Capital Management, LLC, an investment adviser (&quot;WCM&quot;) and Richard S. Spencer III (&quot;Spencer&quot;), a manager and the majority member of WCM.  Each Reporting Person disclaims membership in a group with any non-reporting person within the meaning of Rule 13d-5(b)(i) and Rule 16a-1(a)(1) under the Exchange Act.</footnote>
        <footnote id="F2">This amount includes securities owned directly in various accounts managed by WCM.  These include investment limited partnerships of which WCM is the general partner and investment adviser and separately managed accounts in which neither WCM nor Spencer has any ownership or other economic interest other than entitlement to investment advisory compensation.  Spencer and WCM disclaim beneficial ownership of any securities except to the extent of their respective pecuniary interests.</footnote>
        <footnote id="F3">This is a voluntary filing.  As of April 1, 2005 certain securities were transferred from one account managed by WCM to other accounts managed by WCM.  This event did not result in any change in WCM's or Spencer's pecuniary interest in any securities reflected in the Tables.</footnote>
        <footnote id="F4">Some accounts pay WCM performance-based compensation; others pay only asset-based compensation.  WCM may, in the future, become entitled to performance-based compensation from one or more of the accounts that currently pay only asset-based compensation.  WCM and Spencer specifically disclaim any beneficial interest in securities held by accounts that do not pay performance-based compensation and in securities held by accounts that do pay performance-based compensation except to the extent WCM receives such compensation under circumstances in which that receipt does not qualify for the exclusion in Rule 16a-1(a)(2)(ii)(C)(1) and (2).</footnote>
