SELLING STOCKHOLDERS

        We originally issued the 3.25% Convertible Notes in a transaction exempt from the registration requirements of the Securities Act. Selling stockholders, including their transferees, pledgees or donees or their successors (all of whom may be selling stockholders), may from time to time offer and sell pursuant to this prospectus any or all of the Class C common stock into which the 3.25% Convertible Notes are convertible or otherwise issuable on account of the notes. When we refer to the "selling stockholders" in this prospectus, we mean those persons listed in the table below, as well as their transferees, pledges or donees or their successors.

        The table below sets forth the name of each selling stockholder, the number of shares of our Class C common stock issued or issuable upon conversion of the 3.25% Convertible Notes or otherwise issuable to the selling stockholder on account of the 3.25% Convertible Notes that may be offered pursuant to this prospectus. Unless set forth below, none of the selling stockholders has had within the past three years any material relationship with us or any of our predecessors or affiliates. The information is based on information provided by or on behalf of the selling stockholders to us in a selling stockholder questionnaire and is as of the date specified by the selling stockholders in such questionnaires. The selling stockholders may offer all, some or none of the Class C common stock into which the 3.25% Convertible Notes are convertible, if and when converted, as well as any other shares of our common stock issuable on account of the 3.25% Convertible Notes to the selling stockholders. We have assumed for purposes of the table below that the selling stockholders will sell all of their Class C common stock issuable upon conversion or otherwise on account of the notes pursuant to this prospectus and that any other shares of Class C common stock beneficially owned by the selling stockholders will continue to beneficially owned by them. In addition, the selling stockholders identified below may have sold, transferred or otherwise disposed of all or a portion of their 3.25% Convertible Notes since the date on which they provided the information regarding their 3.25% Convertible Notes in transactions exempt from the registration requirements of the Securities Act.

(1)
Information regarding the selling stockholders may change from time to time. Any such changed information will be set forth in supplements to this prospectus if required.

(2)
Assumes for each $1,000 in principal amount of notes a maximum of 45.4545 shares of Class C common stock could be received upon conversion or otherwise on account of the notes. The conversion rate is subject to adjustment as described in the indenture. As a result, the number of shares of common stock issuable upon conversion of the notes may increase or decrease in the future. Excludes fractional shares. Holders will receive a cash adjustment for any fractional share amount resulting from the conversion of the notes.

(3)
Based on an estimate of 62,784,250 shares of Class C common stock outstanding as of June 17, 2016. In calculating this amount for each holder, we treated as outstanding the number of shares of Class C common stock issuable on account of all of that holder's notes, but we did not assume conversion of any other holder's notes.

        Information concerning the selling stockholders may change from time to time and any changed information will be set forth in supplements to this prospectus if and when necessary. Similarly, holders of 3.25% Convertible Notes not identified in this prospectus as selling stockholders may be identified, and corresponding information regarding an offer of Class C common stock by them included, in supplements to this prospectus if and when necessary.

        In addition, the conversion price, and therefore, the number of shares of common stock issuable upon conversion of the notes, is subject to adjustment in certain circumstances. Accordingly, the aggregate principal amount of notes and the number of shares of common stock into which the notes are convertible may increase or decrease. The conversion rate for the 3.25% Convertible Notes initially equals 36.3636 shares of common stock per $1,000 in principal amount of 3.25% Convertible Notes. The conversion rate is subject to adjustment upon the occurrence of certain specified events but will not be adjusted for accrued and unpaid interest. The indenture governing the 3.25% Convertible Notes provides, among other things, that the conversion rate will be adjusted:

S-4


        In addition, upon the occurrence of a make-whole fundamental change (as defined in the indenture), we will, in certain circumstances, increase the conversion rate by a number of additional shares for a holder that elects to convert its 3.25% Convertible Notes in connection with such make-whole fundamental change. A "make-whole fundamental change" includes:

        Notwithstanding the foregoing, in no event will the conversion rate be increased in excess of 45.4545 shares per $1,000 principal amount of 3.25% Convertible Notes as a result of a "make-whole fundamental change."
