----------

(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.


                                       3


(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.

(5)  Deephaven Domestic Convertible Trading Ltd. owned $2,000,000 aggregate
     principal amount of Holdings' 12 1/2% senior discount notes due 2010.

(6)  DIA High Yield Bond Fund owned $2,750,000 aggregate principal amount of
     Holdings' 11 1/4% senior discount notes due 2009.

(7)  Hallmark Master Trust High Yield owned $1,550,000 of Holdings' 11 1/4%
     senior discount notes due 2009.

(8)  Morgan Stanley & Co. Incorporated was the placement agent for the
