        <footnote id="F3">Dividends credited to the reporting person's Deferred Stock Unit (DSU) account will be credited in DSU's based on the average of the high and the low sale price of Tyco common stock on the dividend date. Distribution under the Plan will first occur upon (i) 30 days following termination of the grantee's employment with the Company (except in the event of Termination for Cause), or (ii) a Change in Control.  Upon such date of termination or Change in Control, as the case may be, the Company shall issue to the grantee the number of shares of Tyco common stock equal to the aggregate number of vested DSUs credited to the grantee.</footnote>
