(1) Assumes that the full amount of the notes held by the selling holder is
being offered for registration hereunder.

(2) Because the selling holders may, pursuant to the prospectus, offer all or
some portion of the notes and shares they presently hold or, with respect
to shares, have the right to acquire upon conversion of such notes, we
cannot predict the amount or percentage of the notes and shares that will
be held by the selling holder upon termination of any such sales. In

addition, the selling holders identified above may have sold, transferred
or otherwise disposed of all or a portion of their notes and shares since
the date on which they provided the information regarding their notes and
shares in transactions exempt from the registration requirements of the
Securities Act. See "Plan of Distribution." The selling holders may sell
all, part or none of the notes or shares listed in the table. The amounts
listed in the table assume that each selling holder sells all of its
convertible notes and/or shares of common stock underlying such notes.

(3) Assumes that the full amount of the notes held by the selling holder is
converted into shares of common stock at the conversion price and offered
hereunder by such selling holder.

(4) The conversion price and the number of shares issuable upon conversion of
the notes are subject to adjustment under certain circumstances. See
"Description of Notes--Conversion of Notes." Section 15.3 of the indenture
governing the convertible notes provides that if any fractional shares of
common stock are issuable upon conversion of the notes, Holdings may either
pay cash in lieu of such fractional shares or round up the number of shares
issuable upon conversion. The number of shares reported in the table
assumes that Holdings rounds up the number of shares issued upon
conversion. We expressly reserve the right to pay cash in lieu of
fractional shares, and any decision as to whether pay cash or round up for
fractional shares will be made at the time the notes are surrendered for
conversion.
