*   Less than 1%.

(1) Assumes conversion of all of the holder's LYONs at a conversion rate of
    7.7062 shares of common stock per $1,000 principal amount at maturity of the
    LYONs. However, this conversion rate will be subject to adjustment as
    described under "Description of LYONs--Conversion Rights." As a result, the
    amount of common stock issuable upon conversion of the LYONs may increase or
    decrease in the future.

(2) Calculated based on 63,828,321 shares of common stock outstanding as of
    August 30, 2001. In calculating this amount, we treated as outstanding that
    number of shares of common stock issuable upon conversion of all of a
    particular holder's LYONS. However, we did not assume the conversion of any
    other holder's LYONS.

(3) Information about other selling security holders will be set forth in
    prospectus supplements, if required.

(4) Assumes that the holders of LYONS, or any future transferees, pledgees,
    donees or successors of or from any such holder of LYONS, do not
    beneficially own any common stock other than the common stock issuable upon
    conversion of the LYONS at the initial conversion rate.

(5) The figures in this column are based on information supplied to us, as of
    June 21, 2002, by the respective selling security holders named in the
    table. As of that date, these selling security holders had supplied us with
    information indicating that, collectively, they owned more than $567,285,000
    aggregate principal amount at maturity of LYONS (which would be convertible
    into more than 4,371,612 shares of common stock), reflecting, we believe,
    that one or more selling security holders supplied us with information for
    inclusion in the table and then sold their LYONS in transactions exempt from
    the registration requirements of the Securities Act to persons who also
    supplied us with information with respect to the same LYONS. However, since
    this prospectus would not be applicable to any sale of LYONS after they have
    been publicly sold utilizing this prospectus, no more than 567,285,000
    principal amount at maturity of LYONS could be sold utilizing this
    prospectus and, accordingly, the $567,285,000 total in this column has been
    retained and represents the maximum principal amount at maturity of LYONS
    that could be sold hereunder.

    We prepared this table based on the information supplied to us as of
June 21, 2002, by the selling security holders named in the table. The selling
security holders listed in the above table may have sold

                                       6

or transferred, in transactions exempt from the registration requirements of the
Securities Act, some or all of their LYONS since the date on which the
information is presented in the above table. Information about the selling
security holders may change over time. Any changed information supplied to us
will be set forth in future prospectus supplements.

    Because the selling security holders may offer all or some of their LYONS or
the underlying common stock from time to time, we cannot estimate the amount of
the LYONS or the underlying common stock that will be held by the selling
security holders upon the termination of any particular offering. See "Plan of
Distribution."

    INVESTING IN THE LYONS INVOLVES RISKS THAT ARE DESCRIBED IN THE "RISK

    NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES
COMMISSION HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR PASSED UPON THE

CRIMINAL OFFENSE.
