The information appearing under the heading “Selling Stockholders” beginning on page 3 of the related prospectus, as previously supplemented, is amended and restated in its entirety by the information below.

SELLING STOCKHOLDERS

Our 3⁷/8% Convertible Senior Notes due 2011 (the “notes”) were originally issued by us to and immediately resold by Banc of America Securities LLC and J.P. Morgan Securities, Inc. in transactions exempt from the registration requirements of the Securities Act to persons reasonably believed by the initial purchasers to be “qualified institutional buyers” as defined by Rule 144A under the Securities Act. Selling stockholders, including their transferees, pledgees, donees and successors, may from time to time offer and sell pursuant to this prospectus and any accompanying prospectus supplement any or all of the shares of our common stock that we may issue upon the conversion of the notes.

The table below sets forth the name of each selling stockholder and the number of shares of our common stock that would become beneficially owned by each selling stockholder should we issue our common stock that may be offered pursuant to this prospectus upon conversion of the notes. We have prepared the table below based on information provided to us by or on behalf of the selling stockholders on or prior to June 29, 2007. The selling stockholders may offer all, some or none of the shares of our common stock that we may issue upon the conversion of the notes. Accordingly, we cannot estimate the number of shares of our common stock that will be held by the selling stockholders upon consummation of any of these sales. In addition, the selling stockholders identified below may have acquired, sold, transferred or otherwise disposed of, in transactions exempt from the registration requirements of the Securities Act, all or a portion of their notes or shares of our common stock since the date on which they provided the information regarding their notes.

The number of shares of our common stock issuable upon the conversion of the notes shown in the table below assumes conversion of the full amount of notes held by each selling stockholder at the initial conversion rate of 22.1867 shares of our common stock per $1,000 principal amount of notes and a cash payment in lieu of any fractional share, assuming 10% annual growth in our dividend rate and 25% quarterly growth in the market price of our common stock. Effective June 14, 2007, the conversion rate was adjusted to 22.2736 shares per $1,000 principal amount of notes and is subject to further adjustment in certain events. Accordingly, the number of shares of our common stock issued upon the conversion of the notes may increase or decrease from time to time. The number of shares of our common stock owned by the other selling stockholders or any future transferee from any such holder assumes that they do not beneficially own any shares of common stock other than the common stock that we may issue to them upon the conversion of the notes.

Based upon information provided by the selling stockholders, none of the selling stockholders or their affiliates has, or within the past three years has had, any material relationship with us or any of our predecessors or affiliates.

To the extent any of the selling stockholders identified below are broker-dealers, they may be deemed to be, under interpretations of the staff of the Commission, “underwriters” within the meaning of the Securities Act.

Information about the selling stockholders may change over time. Any changed information will be set forth in supplements to this prospectus, if required.
