This conversion rate is subject to adjustment as described under "Description of Debentures -Conversion Rights - Adjustments to Conversion Rate" in the prospectus. As a result, the amount of common stock issuable upon conversion of the debentures may increase or decrease in the future. |
| (2) | Specific information about these holders will be set forth in supplements or amendments to the prospectus, if required. |
| (3) | The total principal amount of debentures at maturity listed above is more than $165,000,000 because certain of the above-listed selling securityholders may have, without notifying us, transferred debentures or otherwise reduced their position pursuant to transactions exempt from the registration requirements of the Securities Act of 1933, as amended ("Securities Act"). The maximum amount at maturity of debentures that may be sold under the prospectus, as supplemented, will not exceed $165,000,000. |
_________________________
The principal amounts of the debentures provided in the table above are based on information provided to us by the selling securityholders at various dates through August 2, 2004. Since the date on which each selling securityholder provided the information above, such selling securityholder may have sold, transferred or otherwise disposed of all or a portion or its debentures in a transaction exempt from the registration requirements of the Securities Act.
