        <footnote id="F3">Defered Stock Units (DSUs) were issued under the Tyco International Ltd. (the Company) 2004 Stock and Incentive Plan (the Plan) at a DSU value based on the average price of Tyco common stock for the 60-days prior to the grant.  The DSUs are immediately vested upon grant.  Dividends will be credited in DSUs to the grantee's account 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 service as a member of the Board of Directors of 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>
