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

The tender offers for all of the Notes remain open and are scheduled to expire at 12:00 midnight, New York City time on Thursday, May 24, 2007, unless extended or earlier terminated (the "Expiration Date"). Holders of Notes who tender their Notes after the Early Consent Date specified in the relevant tender offer and consent solicitation document, but before the Expiration Date, will be eligible to receive the Total Consideration less the early consent payment of $30.00.

The following table sets forth the pricing terms for the convertible U.S. debt securities due 2023 of the issuer subject to the tender offers and consent solicitations (the "2023 Convertible Notes"):

The purchase price for each $1,000 principal amount of 2023 Convertible Notes (the "2023 Convertible Notes Purchase Price") is the sum of:

For purposes of this calculation, "Weighted Average Price" means the arithmetic average of the daily volume-weighted average price of Tyco's common shares, par value $.20 per share, for the ten trading days prior to and including May 22, 2007. The daily volume-weighted average equals the daily volume-weighted average price for Tyco's common shares on the New York Stock Exchange during the period beginning at 9:30:01 a.m., New York City time (or such other time as is the official open of trading at the New York Stock Exchange) and ending at 4:00:00 p.m., New York City time (or such other time as is the official close of trading at the New York Stock Exchange) as reported by Bloomberg Financial Services through its "Volume at Price" function. The Weighted Average Price and the variable cash component of the purchase price are rounded to the nearest whole cent.

Holders of the 2023 Convertible Notes must tender their 2023 Convertible Notes and deliver their consents by 12:00 midnight, New York City time, on May 24, 2007, unless such date is extended or earlier terminated, to be eligible to receive the 2023 Convertible Notes Purchase Price.
