The total consideration for each $1,000 principal amount of U.S. Notes (the “Total Consideration”) will equal the present value of the remaining interest and principal payments on such U.S. Notes, calculated as set forth in the relevant tender offer and consent solicitation document, based on a yield to maturity of the U.S. Treasury reference security (the “UST Reference Security”) for such U.S. Notes (the “Reference Yield”) plus the fixed spread indicated in the table above.

The Dealer Managers will calculate the Reference Yield in accordance with standard market practice based on the bid-side price of the UST Reference Security for such Notes as displayed on the relevant Bloomberg pages as of 2:00 p.m., New York City time, two business days prior to the Expiration Date. Tyco expects to publicly announce the pricing information for the tender offers via subsequent press release.
