        <footnote id="F1">The performance objectives governing 50% of these shares of Restricted Stock have been met, and, accordingly, these shares will now be reported in Table 1 as directly owned shares of Restricted Stock.  The restrictions lapse on 50% (1/2) of the shares on the first anniversary of the date of grant, and, provided the performance objectives for the second 1/2 are met, 50% (1/2) on the second anniversary of the date of grant (7/25/2007).</footnote>
        <footnote id="F2">Each performance based restricted share represents a contingent right to receive one share of CYH common stock.  There are two elements to the lapsing of the restriction; first, the Company must achieve specified targeted amount of earnings per share from continuing operations, and if the performance objective is met, the vesting restrictions will lapse in 1/3 increments on the first, second and third anniversary of the date of grant.</footnote>
