(1)
The principal amount of notes shown to be beneficially owned and offered by the selling holders identified in this prospectus supplement, when added to the aggregate principal amount of notes shown to be beneficially owned and offered by the selling holders identified in all prior prospectus supplements and our prospectus dated November 24, 2000, may be in excess of the total principal amount of notes registered. This excess results from sales or transfers of all or a portion of the notes held by such previously identified selling holders in transactions exempt from the registration requirements of the Securities Act of 1933, as amended, after the date on which they provided the information concerning their notes. Thereafter, subsequent purchasers requested registration to sell the notes acquired from and registered on behalf of a prior selling holder. The number of shares of common stock offered is similarly affected.

(2)
The number of shares of common stock shown to be beneficially owned before this offering does not include shares of common stock into which the notes being offered are convertible.

(3)
Assumes conversion of all the holder's notes at a conversion price of $73.935 per share of common stock and resale of all shares of common stock offered hereby.

    Information concerning the selling holders may change from time to time and any changed information will be set forth in supplements or amendments to the prospectus if necessary. In addition, the per share conversion price, and therefore the number of shares of common stock issuable upon conversion of the notes, is subject to adjustment. As a result, the aggregate principal amount of the notes and the number of shares of common stock into which the notes are convertible may increase or decrease.
