(1)  Assumes conversion of all of the holder's debentures at a conversion rate
     of 9.5111 shares of common stock per $1,000 principal amount at maturity
     of the debentures. This conversion rate is subject to adjustment, however,
     as described under "Description of Debentures--Conversion
     Rights--Adjustments to Conversion Rate" beginning on page 22 of the
     prospectus. As a result, the number of shares of common stock issuable
     upon conversion of the debentures may increase or decrease in the future.

(2)  Calculated based on Rule 13d-3(d)(i) of the Exchange Act using 481,958,088
     shares of common stock outstanding as of September 30, 2001. In
     calculating this amount, we treated as outstanding the number of shares of
     common stock issuable upon conversion of all of that particular holder's
     debentures. However, we did not assume the conversion of any other
     holder's debentures.

                            -----------------------

     You should carefully consider the matters discussed under the caption
"Risk Factors" starting on page 11 of the Prospectus.
