| (1) | Assumes conversion of all of the holders’ debentures at the maximum initial conversion rate of 27.7316 shares per debenture. However, the maximum conversion rate is subject to adjustment as described under “Description of Debentures—Conversion Rights—Conversion Rate Adjustments.” As a result, the amount of common stock issuable upon conversion of the debentures may increase or decrease in the future. |
| (2) | Assumes that all of the debentures and/or all of the common stock into which the debentures are convertible are sold. No selling securityholder will own more than 1% of our outstanding common stock after the offering by such securityholder. | |
| (3) | Information about other selling securityholders will be set forth in an amendment to the registration statement of which this prospectus is a part or in prospectus supplements, as required. | |
| (4) | Assumes that any other holders of debentures, or any future transferees, pledgees, donees or successors of or from any such other holders of debentures, do not beneficially own any common stock other than the common stock issuable upon conversion of the debentures. |
We prepared this table based on the information supplied to us by the selling securityholders
named in the table. The selling securityholders listed in the above table may have sold or
transferred, in transactions exempt from the registration requirements of the Securities Act, some
or all of their debentures since the date on which the information is presented in the above table.
Information about the selling securityholders may change over time. Any changed information will be
set forth in prospectus supplements and/or amendments to the registration statement of which the
prospectus, as supplemented by this prospectus supplement, is a part.
Because the selling securityholders may offer all or some of their debentures or the
underlying common stock from time to time, we cannot estimate the amount of the debentures or the
underlying common stock that will be held by the selling securityholders upon the termination of
any particular offering. See the section of the prospectus captioned “Plan of Distribution.”
None of the named selling securityholders nor any of their affiliates, officers, directors or
principal equity holders has held any position or office or has had any material relationship with
us within the past three years.
The date of this prospectus supplement is October 13, 2006
